PVC Decking in Boise
100% synthetic cellular PVC decking — zero moisture absorption, zero wood fiber, zero rot. AZEK and TimberTech Advanced PVC installed by Iron Crest Remodel for Boise and Treasure Valley homeowners who want the longest-lasting synthetic deck surface available.
PVC decking is made from 100% synthetic cellular polyvinyl chloride — the same base polymer family used in plumbing pipe, vinyl siding, and window profiles. The defining word is cellular: the board is foamed into a structure of millions of tiny closed cells, then wrapped on all four sides in a protective polymer cap. Unlike capped composite, which blends recycled wood flour with plastic and then caps it, true PVC decking contains zero wood fiber. That single fact drives almost everything else on this page. With no organic content, the board cannot absorb water, cannot feed mold, and cannot rot — not at the surface, not at a cut end, not after two decades of Treasure Valley winters.
The cellular core also makes PVC the lightest synthetic decking on the market. A standard 5.5-inch PVC board runs roughly 1.6 to 1.8 pounds per linear foot, against roughly 2.2 to 2.8 pounds for a comparable capped composite board. Lighter boards put less dead load on the substructure, which matters on elevated decks, on re-decking projects over an older frame, and on long cantilevers. They are also simply easier to handle cleanly on site, which protects the cap during installation.
The four-sided cap is where the engineering lives. It carries the color, the wood-grain embossing, the traction texture, and the UV stabilizers that keep the board from chalking and fading under Idaho sun. Because the cap fully encapsulates the board including the bottom, water has no porous path in even where boards are cut on site — an advantage over older uncapped products and a meaningful one in our freeze-thaw climate. This page covers PVC specifically; if you are weighing it against other surfaces, see our composite decking and wood decking pages, or our overall guide to the best decking material for Boise.
Cap Technology, Traction & Why It Matters Here
The cap is co-extruded onto the cellular core in the same production pass, so it is bonded rather than glued and will not delaminate the way an after-applied film could. Within the cap, titanium-dioxide-based UV packages reflect and stabilize against ultraviolet energy, which is the property that lets manufacturers publish long fade-and-stain warranties. The same cap carries the surface texture — modern PVC lines are wire-brushed, hand-scraped, or low-gloss embossed, and that texture is what provides slip traction when the deck is wet or dusted with the fine Treasure Valley grit that blows in every summer. A non-porous surface that still has real mechanical traction is exactly what you want around a pool: the water beads and runs off instead of soaking in, but the foot still grips.
Leading PVC Decking Brands
AZEK
Widely treated as the premium benchmark in cellular PVC. AZEK pairs a 100% PVC core with a proprietary polymer cap engineered for fade, scratch, and stain resistance, and offers multiple lines spanning price points and grain depth. We recommend confirming current colors and warranty terms on the manufacturer site, since lines and coverage are periodically revised.
TimberTech Advanced PVC
Sister brand to AZEK under the same parent company. The Advanced PVC line shares the same 100% cellular PVC core with a streamlined palette, typically at a modestly lower price. For most Treasure Valley homeowners the practical choice between the two comes down to color and texture preference rather than core moisture performance.
“Synthetic decking” is often discussed as one category, but 100% PVC and capped composite are different materials that behave differently in Idaho. The headline contrast is the core: composite has a wood-flour-and-plastic core under its cap, while PVC has a foamed all-polymer core and no organic content at all. Everything below flows from that.
Weight, Water & Mold
Capped composite is well sealed on its faces, but its core still contains wood flour, and any exposed cut, drilled hole, or factory end leaves a path where a small amount of moisture can reach organic material. Quality capped composites typically absorb only a fraction of a percent of water, which is excellent — but it is not zero. PVC is zero, because there is nothing organic to wet and nothing for mold or mildew to colonize from the inside. For most well-built, well-drained decks that distinction is academic. It stops being academic when the deck is constantly wet, splashed, or unable to dry out, which is precisely where the Treasure Valley’s pool decks, hot-tub surrounds, and low ground-hugging decks live.
Low Substructure Ventilation
A deck only a step or two off the ground cannot breathe underneath. Air does not move, the framing bay stays humid after snowmelt and irrigation, and any decking with organic content dries slowly and works the frame harder. This is the single clearest case where PVC earns its premium in Idaho: it does not care that the underside never dries. We still detail the wood frame for drainage and use ground-contact-rated lumber and corrosion-resistant hardware, because the framing — not the PVC — is the part still exposed to that damp micro-climate.
| Property | 100% PVC Decking | Capped Composite |
|---|---|---|
| Core composition | Foamed all-polymer, no wood | Wood flour + recycled plastic |
| Moisture absorption | Essentially zero | Typically a fraction of 1% |
| Weight (per linear ft) | ~1.6–1.8 lbs (lighter) | ~2.2–2.8 lbs |
| Mold / mildew from within | No — no organic content | Low — wood flour present in core |
| Thermal expansion | Higher — gapping detail critical | Lower — wood flour restrains movement |
| Surface heat in full sun | Often cooler than same-color composite | Warmer; both hot in dark colors |
| Stain resistance | Excellent — non-porous surface | Good — capped but wood-cored |
| Installed cost | Premium tier | Mid-tier synthetic baseline |
| Cost premium | Roughly 15–25% over composite* | Baseline synthetic price |
| Fade / structural warranty | Long limited — verify current terms | Long limited — verify current terms |

When PVC Clearly Leads
PVC pulls decisively ahead of composite in full-moisture and poorly ventilated situations: pool and hot-tub surrounds, lakefront and riverfront decks, low decks close to grade where the underside never dries, and covered outdoor kitchens where grease and wine hit the boards weekly. In those cases the zero moisture absorption is not a marketing line — it is the whole reason to spend the premium. For a standard, well-drained, well-ventilated backyard deck, that advantage is far less relevant, and a good capped composite is often the smarter budget decision.
This is the section most homeowners never read and most failed synthetic decks needed. Of everything that separates a PVC deck that looks perfect at year ten from one that has buckled or pulled open at the butt joints, installation detailing around thermal movement is the biggest single factor — and it matters more in the Treasure Valley than in milder climates.
Why PVC Moves More
In capped composite, the wood flour in the core acts like aggregate in concrete and physically restrains the plastic from moving much. Cellular PVC has no such filler, so for a given temperature change it expands and contracts more than composite. Manufacturer literature commonly describes movement on the order of roughly 1/8 to 1/4 inch over a 16-foot board across a large seasonal swing — but we treat that as an indicative range, not a fixed number, because the real figure depends on the specific product and the actual temperature delta. The point is not the exact fraction; the point is that the movement is real, predictable, and must be designed for.
Why Boise Amplifies It
Treasure Valley decks see an unusually wide temperature band. A winter night can sit well below freezing while a dark board in direct July sun can reach a surface temperature far above the air temperature — the swing a deck board actually experiences over a year here is well over 100 degrees of material temperature. The wider the swing, the more total movement the connection has to absorb, which is why a gap and fastening detail that is fine in a mild coastal climate can fail in Idaho if copied without adjustment.
Gapping to Install Temperature
We size end-to-end gaps from the manufacturer’s gap chart using the actual board temperature at the moment of installation, not a single number. A board set on a 40-degree morning needs a tighter end gap than one set at 95 degrees, because the cold board will grow toward the warm board. Side gaps are set by the fastener system. Material is acclimated on site before final cutting so the boards are at a representative temperature when they are locked in.
Hidden Fasteners That Let Boards Float
Most premium PVC uses a hidden-clip system seated in a side groove that holds the board down while still allowing it to slide as it expands. Where face screws are required — stair nosings, certain perimeter details — they are placed and color-plugged per the manufacturer. Long runs are never rigidly pinned at both ends, which is the classic mistake that turns normal expansion into a visible buckle.
Breaker Boards & Long Runs
On long decks we plan breaker boards — an intentional perpendicular board that splits one long run into two shorter ones — so movement is distributed across multiple controlled joints instead of stacking up at a single butt seam. Breaker boards also let us land board ends on solid blocking and give the deck a deliberate, designed look rather than a random splice.
Picture-Frame & Mitered Borders
Picture-frame borders and mitered corners are beautiful but unforgiving with a high-expansion material: a tight miter set on a cold day can open in summer. We detail border joints, fastening, and substructure blocking specifically for PVC movement so the perimeter still looks crisp across the full Treasure Valley temperature range, not just on install day.
Boise’s high-desert profile — roughly 2,700-foot elevation, a long sunny season, a wide annual temperature band, real winter freeze-thaw cycling, low ambient humidity, and seasonal snow load — sets the conditions a PVC deck has to live in here. Below is how each factor actually interacts with cellular PVC, stated honestly.
Freeze-Thaw Immunity
Freeze-thaw damage works by water entering a porous material, freezing, expanding, and prying the material apart over many cycles. The Treasure Valley delivers a great many freeze-thaw crossings each winter. Because 100% PVC absorbs essentially no water, there is no internal moisture to freeze, so the primary cold-climate degradation mechanism for decking simply does not act on the board. This is PVC’s clearest structural advantage in our climate.
UV at Elevation & Color Choice
Higher elevation means somewhat more ultraviolet energy reaching the deck than at sea level, and Boise gets a long sun season. PVC caps include UV stabilizers and carry long limited fade warranties, but every color lightens slowly over decades and darker tones show heat and weathering changes more than mid-tones. For exposed south- and west-facing Treasure Valley decks we generally steer clients toward mid-range colors that age gracefully, and we ask homeowners to confirm the current fade-warranty terms on the manufacturer site.
Heat Underfoot — Honestly
Same-color PVC often runs cooler underfoot than capped composite because its cellular core carries less dense mass, but we will not pretend any synthetic deck stays cool in full Boise sun — dark boards get hot regardless of material. Color is the dominant lever: a light board can be far cooler than a dark one in the same line. Around pools and bare-foot zones we recommend lighter PVC colors and set realistic expectations rather than overselling.
Snow Load & Snow Removal
PVC’s non-porous surface sheds snowmelt rather than soaking it up, so it does not gain weight or saturate the way wood can. Local ground snow loads are carried by the substructure, which we engineer to code for the project site. For removal, use a plastic or rubber-edged shovel rather than a metal blade that can score the cap, and prefer calcium-chloride or magnesium-chloride ice melt over rock salt, which can leave residue on the surface.
Dry-Climate Dust & Pollen
The Treasure Valley’s dry, windy season deposits fine grit and seasonal pollen on every horizontal surface. On PVC this is purely cosmetic — it rinses off and never feeds mold — but grit left in board gaps can act as an abrasive under foot traffic, so seasonal rinsing and clearing the gaps is the practical maintenance reality here, not sealing or staining.
Wide Annual Temperature Band
The same wide temperature swing that makes thermal-expansion detailing critical is, handled correctly, a non-issue: PVC itself is unbothered by the heat and cold. The risk lives entirely in the connection, not the material, which is why we treat gap charts, float fasteners, and breaker boards as mandatory rather than optional on Treasure Valley PVC decks.
PVC is the highest-performing synthetic deck surface available, but it is not automatically the right choice for every project. Here is a straight assessment, written for Boise and the Treasure Valley specifically rather than a generic brochure.
Where PVC Wins
- Essentially zero moisture absorption — no rot, no internal mold, even at cut ends
- Best synthetic choice for poolside, hot tubs, lakefront, and low decks with poor underside ventilation
- Lightest synthetic board — less dead load, ideal for re-decking an older sound frame
- Non-porous surface resists food, wine, and grease staining on outdoor-kitchen decks
- Immune to freeze-thaw cycling, the main cold-climate decking failure mechanism here
- Long limited structural and fade warranties from the manufacturer (verify current terms)
- Often cooler underfoot than same-color capped composite in direct sun
- Will not splinter, check, or crack like wood; no annual sand-stain-seal cycle
When PVC Is NOT the Right Pick
- Cost: the premium over capped composite can be better spent on deck size or railing quality
- Look: some homeowners find certain PVC boards read more uniform than wood-flour composite or real wood
- Expansion: very long rigid runs demand disciplined detailing; a fighting design may favor composite or wood
- Dark colors still get hot in full Boise sun — PVC reduces, does not eliminate, surface heat
- Deep scratches cannot be sanded out the way they can on real wood
- Fewer brand and color choices than the broad composite market
If any of the right-column points apply to your project, that is a reason to talk it through, not a dealbreaker. We would rather recommend composite or wood when it is the better whole-project decision than upsell PVC by default. Our broader Boise decking material guide walks through that comparison without bias toward any one material.
PVC sits at the top of the synthetic decking price ladder. Installed, it generally runs a meaningful premium over capped composite — commonly cited around 15 to 25% more depending on the product line, the deck design, and site conditions. We quote real numbers only after seeing the project, because access, elevation changes, demolition of an old deck, railing selection, stairs, and substructure condition move the total far more than the board choice alone. We do not publish fabricated brand prices here; the honest answer is a free in-home estimate.
What Actually Drives the Number
The board is only one line on the estimate. The substructure — footings to the local frost line, properly sized and spaced joists, corrosion-resistant hardware — is where code and longevity live, and on a re-deck it is also where surprises hide once the old boards come off. Hidden-fastener systems cost more than face screws but are part of why a PVC deck looks clean for decades. Picture-frame borders, breaker boards, multi-level designs, stairs, and railings each add labor. A simple ground-level rectangle and a multi-level deck with mitered borders are very different projects even at the same square footage.
When the Premium Pays Off — and When It Does Not
The PVC premium is most defensible when the deck is genuinely high-moisture or poorly ventilated: pool and hot-tub surrounds, waterfront properties, low ground-hugging decks, and covered outdoor kitchens. In those cases you are buying the one property composite cannot fully match — zero moisture absorption — and over a long ownership horizon the no-sand, no-stain, no-seal maintenance profile compounds in your favor. The premium is harder to justify on a standard, well-drained, well-ventilated backyard deck for an owner who may move within a few years; there, a quality capped composite usually delivers most of the real-world performance for less. We will tell you which case you are in.

A PVC deck is only as durable as the frame under it and the fasteners holding it together. The boards may outlive the house, but a poorly built or under-ventilated substructure will fail long before the surface does. Here is how we build for the long PVC lifespan the material is capable of.
The Substructure
We build on a code-compliant pressure-treated frame with footings carried to the local frost line, joists sized and spaced for the chosen PVC product and pattern (commonly 16 inches on center for straight runs and tighter for diagonal layouts and wide planks), and corrosion-resistant connectors and fasteners. Even though PVC will not rot, the frame can, so drainage and ventilation under the deck are designed in, not left to chance.
Hidden Fasteners & Breaker Boards
Most premium PVC installs with a hidden-clip system that holds each board while letting it float for thermal movement. Breaker boards split long runs into controlled segments so expansion is distributed, not concentrated. Where face screws are required by the manufacturer for stairs or specific details, we use approved screws with color-matched plugs. All fastening follows the manufacturer’s instructions so the product warranty stays valid.
Lifespan Expectations
Manufacturers project multi-decade service life for cellular PVC, frequently in the 30-to-50-plus-year range, and the freeze-thaw immunity supports that in our climate. We present that as a reasonable expectation under normal use, not a guarantee on any one deck, and we point homeowners to the current written manufacturer warranty for the binding terms.
Real Maintenance in Idaho
No sanding, staining, or sealing — ever. Practical care is soap and water a couple of times a year, rinsing seasonal dust and pollen, clearing grit from board gaps, plastic-edged snow tools in winter, and felt pads under furniture. That is the entire maintenance story, and it is the same whether the deck is one year or twenty years old.
PVC can be used for any deck, but its premium is most clearly earned where moisture, spills, and poor ventilation would punish other materials. These are the Treasure Valley situations where we most often recommend it without hesitation.
Pool & Hot Tub Surrounds
Constant splash-out and standing water are exactly where zero moisture absorption matters. The textured cap still gives wet traction, and a lighter color keeps it more bearable underfoot during a 100-degree Boise afternoon.
Covered Outdoor Kitchens
Grease, wine, marinade, and dropped food are weekly events on a cooking deck. PVC’s non-porous surface lets most of it wipe up, and there is no organic core for a missed spill to feed.
Lakefront & Riverfront Decks
Properties along the Boise River, Lake Lowell, or Lucky Peak deal with humidity, splash, and slow-drying conditions. PVC removes the decking from that equation so attention can go to protecting the frame.
Low Decks With Poor Ventilation
Ground-hugging decks cannot breathe underneath and stay damp after snowmelt and irrigation. PVC tolerates that micro-climate far better than wood or even capped composite, which is one of its strongest Idaho use cases.
Within the cellular PVC category, the major lines differ mainly in color selection, surface texture depth, and available plank widths — not in core moisture performance, which is shared across true 100% PVC products. The notes below describe the general positioning of the common tiers; we ask homeowners to confirm current collections, colors, and warranty terms on the manufacturer site before selecting, since lines are periodically revised.
Entry Premium Tier
Most Popular
Mid-toned wood-grain lines
The most popular tier is the entry point into premium cellular PVC: a realistic multi-tonal wood-grain texture in standard plank widths and common 12-, 16-, and 20-foot lengths. It is the line most Treasure Valley homeowners land on because it balances appearance, price, and the full PVC moisture performance.
For Boise homes we most often see warm mid-brown and golden honey tones selected because they sit well against the earth-tone architecture common across the Treasure Valley and weather gracefully under our long sun season. Confirm exact current color names on the manufacturer site.
Premium Texture Tier
Deepest wood grain
Hand-scraped / wire-brushed look
The premium tier carries the deepest, most realistic embossing — hand-scraped and wire-brushed surface textures meant to read like reclaimed or hand-planed hardwood. This is the line to choose when visual authenticity in raking evening light is the top priority and the budget supports it.
Richer, more complex brown and charcoal-undertone colors dominate this tier, often with a wider plank option. The same thermal-expansion detailing discussed above still applies; deeper texture does not change how the board moves with Treasure Valley temperature swings.
Wide-Plank Tier
Fewer seam lines
Large-deck specialist
Wide-plank lines use a broader board to create a bold, modern look with fewer seam lines, which reads especially well on large decks where reducing the number of joints makes the surface feel more expansive and intentional.
Wider boards typically require tighter joist spacing — often 12 inches on center — for proper support, which is a substructure cost and design factor we account for up front rather than discovering on site.

Common questions Treasure Valley homeowners ask about PVC decking, answered honestly by the Iron Crest Remodel deck team.
How long does PVC decking last in Boise’s climate?
Cellular PVC decking is generally expected to last 30 to 50 or more years in the Treasure Valley with virtually no maintenance, and we treat that as a manufacturer-projected range rather than a guarantee on any one job. Because 100% PVC contains no wood fiber, it cannot absorb moisture, which removes the freeze-thaw damage mechanism that shortens the life of wood and, to a lesser degree, capped composite at Boise’s roughly 2,700-foot elevation. AZEK and TimberTech Advanced PVC publish lifetime limited structural warranties plus fade-and-stain warranties commonly cited at 50 years; verify current warranty terms on the manufacturer site, since coverage and exclusions change. Iron Crest Remodel separately backs our installation with a 5-year workmanship warranty.
What is the real difference between 100% PVC and capped composite?
Capped composite has a wood-flour-and-plastic core wrapped in a polymer shell; 100% (cellular) PVC has no organic core at all. In practice that means PVC absorbs essentially zero moisture while quality capped composite typically absorbs a small fraction of a percent at exposed cuts and ends. PVC is also lighter, around 1.6 to 1.8 pounds per linear foot for a standard 5.5-inch board versus roughly 2.2 to 2.8 pounds for comparable composite, and it has no internal wood for mold to feed on. The trade-off is that PVC moves more with temperature and carries a higher price. For a fully shaded, well-drained backyard deck, capped composite is often the better value; for poolside, low-ventilation, ground-hugging, or constantly wet decks, PVC’s moisture immunity is worth the premium.
Why does PVC decking expand and contract more than composite?
All decking moves with temperature, but unfilled cellular PVC has a higher coefficient of thermal expansion than wood-filled composite, because the wood flour in composite restrains movement the way aggregate restrains concrete. Manufacturer literature commonly cites movement in the range of roughly 1/8 to 1/4 inch over a 16-foot board across a large seasonal temperature swing; the exact figure depends on the product and the temperature delta, so we follow each manufacturer’s published gap chart rather than a single rule. The Treasure Valley sees board surface temperatures swing well over 100 degrees between a January night and a black-colored deck in July sun, which is exactly why end gapping and fastening detail matter so much here.
How do you handle PVC thermal expansion during installation in the Treasure Valley?
We size end-to-end gaps off the manufacturer’s gap chart for the actual board temperature at install time, not a fixed number, because a board installed on a cold morning needs a different gap than one installed at 95 degrees. We let material acclimate on site before cutting, fasten with the system the manufacturer specifies (hidden clips that allow the board to float on the joist, or properly placed face screws where required), and avoid pinning long runs rigidly at both ends. On long boards and picture-frame borders we plan breaker boards and detail the perimeter so seasonal movement is distributed instead of concentrated at one butt joint. Skipping this detail is the most common cause of buckled or end-gapped synthetic decks in our climate.
Does PVC decking get hot in the Boise summer sun?
PVC generally runs cooler underfoot than same-color capped composite in direct sun because its cellular core carries less dense mass than wood-filled composite, but no synthetic deck is cool on a 100-degree Boise afternoon, and dark colors get hot regardless of material. Color choice drives surface temperature far more than the PVC-versus-composite difference: a light board can be dramatically cooler than a dark one in the same product line. If barefoot comfort around a pool matters, we steer Boise clients toward lighter PVC colors and set expectations honestly rather than implying any decking stays cool in full high-desert sun.
How does Boise’s elevation and UV affect PVC color and fade warranties?
Boise sits near 2,700 feet, and higher elevation means modestly more ultraviolet energy reaching the deck than at sea level, so UV stability matters here. AZEK and TimberTech Advanced PVC build UV stabilizers into the cap layer and publish long fade-and-stain warranties (commonly cited around 50 years), but those are limited warranties with conditions, and all colors lighten somewhat over decades. Darker colors show heat and very slow weathering changes more than mid-tones, so for west- and south-facing Treasure Valley decks we usually recommend mid-range colors that age gracefully. Confirm the exact current fade warranty and its exclusions on the manufacturer’s site before you buy.
Is PVC decking worth the extra cost over composite in Boise?
PVC carries a meaningful premium over composite, often roughly 15 to 25% more installed depending on the product and project, and that range is an estimate, not a quote. It is worth it when the deck is genuinely high-moisture or hard to ventilate underneath: pool and hot tub surrounds, low decks close to grade, lakefront and riverfront properties, and covered outdoor kitchens where spills are constant. For a standard, well-drained, well-ventilated backyard deck, a quality capped composite usually delivers most of the performance for less money. We will tell you honestly when composite is the smarter spend rather than upselling PVC by default.
When is PVC NOT the right decking choice?
Three honest cases. First, budget: if the premium over capped composite would force you to shrink the deck or cut railing quality, a good composite is the better whole-project decision. Second, look: some homeowners feel certain PVC boards read slightly more uniform or “manufactured” than a wood-flour composite or real wood; in raking evening light that is a matter of taste worth seeing in person. Third, thermal movement: on very long uninterrupted runs with rigid end conditions, PVC’s greater expansion demands disciplined detailing, and where a design fights that, composite or wood may be simpler to execute well. We walk through all three before you commit.
Can you install PVC decking over an existing deck frame in Boise?
Often yes, if the substructure is sound and meets current code. We check that joists are level, properly spaced for the chosen PVC product (commonly 16 inches on center for straight runs and tighter, often 12 inches, for diagonal patterns or wide planks), and free of rot or insect damage. We also inspect the ledger connection and flashing, footing depth relative to the local frost line, and all hardware for corrosion. If the frame passes, re-decking with PVC instead of a full rebuild typically saves a substantial share of the cost, though the exact savings depend entirely on what the inspection finds.
What substructure and fasteners does PVC decking require?
PVC performs only as well as the frame beneath it. We build on a code-compliant pressure-treated structure with footings to the local frost line, joist spacing matched to the specific PVC product and installation pattern, and corrosion-resistant hardware. Most premium PVC uses a hidden-fastener clip system that grips a side groove and lets each board float for thermal movement; some details and stair nosings require approved face screws with color-matched plugs. Adequate ventilation and drainage under the deck still matter even though PVC itself will not rot, because the wood frame can. Fastener choice and spacing follow the manufacturer’s installation instructions for warranty validity.
What is the difference between AZEK and TimberTech Advanced PVC decking?
AZEK and TimberTech are sister brands under the same parent company, and both Advanced PVC lines use a 100% cellular PVC core with no wood fiber. AZEK is generally positioned as the premium tier with the widest color and texture selection; TimberTech Advanced PVC typically offers a streamlined palette at a modestly lower price while sharing the same core moisture performance. Published structural and fade warranties are similar across both, though specific terms differ by product line and change over time, so check current details on the manufacturer site. For most Treasure Valley homeowners the decision comes down to color, texture preference, and budget rather than core performance.
How do you clean and maintain a PVC deck in the Treasure Valley?
Routine care is soap, water, and a soft brush a couple of times a year, plus rinsing off Boise’s seasonal dust and pollen and clearing leaves from gaps so debris does not trap grit against the cap. For snow, use a plastic or rubber-edged shovel rather than a metal blade that can scratch the surface, and prefer calcium-chloride or magnesium-chloride ice melt over rock salt, which can leave residue. PVC is non-porous so most spills wipe up, but deep scratches cannot be sanded out the way wood can, so felt pads under furniture and care with grills and fire features extend the finish. Always follow the manufacturer’s care guidance to keep the stain warranty intact.
Is PVC decking a good choice for low decks close to the ground in Idaho?
It is one of PVC’s strongest use cases. Low, ground-hugging decks have limited airflow underneath, so any decking with organic content stays damp longer and is more prone to mold and accelerated wear on the frame side. Because 100% PVC absorbs no moisture and has nothing for mold to feed on, it tolerates the damp, poorly ventilated micro-climate of a low deck better than wood or even capped composite. We still build the substructure for drainage and use ground-contact-rated framing and corrosion-resistant hardware, since the wood frame, not the PVC, is the part still at risk near grade.
Does Iron Crest Remodel provide a warranty on PVC deck installation in Boise?
Yes. Iron Crest Remodeling Group LLC, doing business as Iron Crest Remodel, backs our deck installation workmanship with a 5-year warranty that is separate from, and in addition to, the manufacturer’s product warranty on the PVC boards themselves. We are licensed and insured in Idaho under registration RCE-6681702 and provide free in-home estimates. The manufacturer warranty covers the material; our workmanship warranty covers how it is built and fastened. We install to the manufacturer’s published instructions specifically so both warranties stay valid for the homeowner.
