From full house repaints to deck staining and trim refreshes — we deliver lasting, weather-resistant results with premium coatings and meticulous surface preparation.
Exterior painting in Boise is a battle against two unrelenting forces: ultraviolet radiation and temperature extremes. With more than 300 sunny days per year and summer temperatures regularly reaching 100–105°F, Boise's south- and west-facing exterior surfaces endure UV exposure that would be extraordinary in most American cities, causing inferior paint systems to chalk, fade, and crack within three to five years. The freeze-thaw cycles of Boise winters — swinging from the mid-teens in January to the mid-60s in March — place additional stress on painted wood and composite surfaces, opening micro-cracks where moisture can intrude before the next UV summer accelerates the damage. Iron Crest Remodel has developed an exterior painting system specifically calibrated to Boise's climate: the right products, the right prep, and a painting season strategy that delivers results built to outlast the conditions.
Protect and transform your home's exterior with professional painting and staining built to withstand Idaho weather.

Exterior painting protects your home from Idaho's intense UV exposure, freeze-thaw cycles, wind-driven rain, and seasonal temperature swings that range from below zero in January to over 100 degrees in July. Professional exterior painting goes far beyond rolling paint on siding — it includes power washing, scraping loose paint, sanding rough surfaces, caulking gaps and joints, priming bare wood, and applying two coats of premium exterior paint rated for the Treasure Valley's demanding climate. The quality of prep work determines how long an exterior paint job lasts; cutting corners on preparation is the number one reason exterior paint fails prematurely. A properly prepped and painted exterior should last 8-12 years in the Boise climate when using quality products and correct application techniques.
Boise homeowners pursue exterior painting for a variety of reasons. Here are the most common situations we see:
Not every exterior painting project is the same. Here are the most common project types we complete in Boise:

Complete painting of all exterior surfaces including siding, trim, fascia, soffits, eaves, and window frames. Includes power washing, scraping, caulking, priming, and two coats of premium exterior paint.

Targeted painting of exterior trim elements that show wear faster than siding. Includes scraping, sanding, priming, and two coats of durable semi-gloss or satin paint.

Cleaning, sanding, and staining wood decks and fences with penetrating or film-forming stain. Includes proper surface preparation, which is critical for stain adhesion and longevity in Boise's sun and moisture conditions.

High-impact refresh of entry and garage doors. Includes sanding, priming, and spray or brush application of durable exterior paint in your chosen color.

Application of semi-transparent or solid-body stain to wood siding, cedar accents, log elements, or timber features. Staining preserves the natural wood grain while providing UV and moisture protection.

Boise has over a century of residential construction, from 1900s Craftsman homes in the North End to 2020s new construction in West Boise and Southeast Boise. This diversity means remodeling contractors encounter a wide range of structural systems, plumbing types, electrical standards, and finish materials.
Craftsman bungalows, Tudor revivals, and foursquare homes with plaster walls, old-growth fir floors, knob-and-tube wiring (in some), galvanized plumbing, and brick or stone foundations. Remodeling these homes requires sensitivity to historic character while updating systems.
Post-war ranch homes and split-levels with hardwood floors, original tile bathrooms, copper plumbing, and 100-amp electrical panels. These homes often need kitchen and bathroom updates, electrical upgrades, and insulation improvements.
Subdivision homes with drywall, builder-grade cabinets, laminate countertops, carpet throughout, and basic builder fixtures. Most plumbing is copper or early PEX. These are the most common candidates for kitchen and bathroom remodels.
Modern construction with PEX plumbing, 200-amp panels, energy-efficient windows, and open floor plans. Remodeling in these homes typically focuses on upgrading builder-grade finishes rather than updating systems.

Material selection affects the look, durability, and cost of your exterior painting. Here are the most popular options we install in Boise:

A premium 100% acrylic exterior paint with exceptional durability, color retention, and mildew resistance. Self-priming on previously painted surfaces. Rated for extreme weather exposure.
Best for: Siding and large exterior surfaces that need maximum weather resistance

A top-tier exterior paint with ColorLock technology for fade resistance. Excellent adhesion and flexibility that resists cracking in temperature extremes. Low-VOC formula.
Best for: South- and west-facing walls that receive intense Boise sun exposure

A high-performance deck and fence stain available in semi-transparent and solid formulas. Provides UV protection, water resistance, and mildew resistance for horizontal wood surfaces.
Best for: Wood decks, fences, pergolas, and horizontal wood surfaces

Premium exterior caulking that remains flexible in Idaho's temperature extremes. Paintable, waterproof, and designed for long-term adhesion to wood, fiber cement, and vinyl surfaces.
Best for: Trim joints, window frames, siding gaps, and penetration sealing

Oil-based or shellac-based primers for blocking stains, tannin bleed on cedar, and ensuring adhesion on bare or weathered wood. Critical for long-lasting exterior paint adhesion.
Best for: Bare wood, cedar trim, stain-blocking, and tannin-prone surfaces

Here is how a typical exterior painting project works from first contact to final walkthrough:
We inspect all exterior surfaces — siding, trim, fascia, soffits, windows, doors, and any wood elements. We identify areas of peeling, cracking, rot, caulk failure, and substrate damage. You receive a detailed written estimate with specific prep and painting scope.
We help you select exterior colors that complement your roof, stone, landscaping, and neighborhood aesthetic. We recommend specific paint products rated for Idaho's climate and apply large test samples on the home so you can evaluate colors in natural light.
All exterior surfaces are power washed to remove dirt, mildew, chalking paint, and debris. Loose and peeling paint is scraped and sanded. Gaps, cracks, and joints are caulked. Bare wood and stained areas are spot-primed. This phase takes as long or longer than the actual painting.
Windows, doors, light fixtures, house numbers, downspouts, and landscaping are carefully masked and protected. Drop cloths cover walkways, driveways, and plantings near the work area.
Bare wood and repaired areas receive primer. Two coats of premium exterior paint are applied — by brush, roller, and airless sprayer as appropriate for each surface. Siding, trim, and detail elements are each painted with the proper technique and sheen.
Window frames, door frames, shutters, and decorative elements receive careful detail painting. All edges, corners, and transitions are inspected and touched up for clean, consistent results.
All masking is removed, overspray is cleaned, landscaping protection is cleared, and we conduct a walk-around inspection with you to verify coverage, color accuracy, and finish quality on every surface.
Here is what to expect for project duration when planning a exterior painting in Boise:
| Phase | Duration | Details |
|---|---|---|
| Assessment and Estimate | 1–3 days | Full exterior inspection, surface condition documentation, color consultation, and detailed written estimate. |
| Color Selection and Scheduling | 1–2 weeks | Final color selections, large-area test samples on the home, and project scheduling. Exterior painting in Boise is best scheduled between April and October for optimal conditions. |
| Power Washing and Prep | 1–3 days | Power washing, scraping, sanding, caulking, and priming. Extensive prep on older homes with significant paint failure may take longer. |
| Priming and Painting | 3–7 days | Primer application on bare surfaces, followed by two coats of exterior paint on all siding, trim, fascia, and detail elements. Weather-dependent scheduling may affect timing. |
| Detail Work and Touch-Ups | 1–2 days | Window trim, door frames, shutters, and decorative elements receive final detail painting. All edges and transitions are inspected and corrected. |
| Final Inspection and Cleanup | 1 day | Remove all masking, clean overspray, clear landscaping protection, and conduct a walk-around inspection with the homeowner. |
Boise range: $2,800 – $18,000
Most Boise projects: $6,500
Exterior painting costs in Boise are driven upward by the local climate demands — the UV and temperature stress conditions that define Boise require premium paint systems (typically $75–$100 per gallon for suitable products) and thorough prep work that cannot be shortcut. Labor rates for experienced exterior painters in Ada County run $50–$70 per hour, reflecting both general market wage growth and the specialized knowledge required to work on Boise's diverse housing stock. The wide range from low to high reflects genuine project diversity: a simple single-story 1,500-square-foot ranch on the Bench with T1-11 siding in good condition is a fundamentally different project from a two-story 3,000-square-foot North End Craftsman with original wood siding, multiple dormers, and detailed trim work. Projects involving wood rot repair, lead paint prep, full stripping of failing previous coatings, or masonry primer on stucco surfaces all add cost. The average of $6,500 reflects the most common project type in Boise: a two-story, 2,200-square-foot home with horizontal lap siding in fair-to-good condition requiring full prep, prime, and two topcoats.
The final cost of your exterior painting in Boise depends on several factors. Here are the biggest cost drivers:
The total exterior surface area is the primary cost driver. A two-story home has significantly more paintable surface and requires ladder or scaffold access, which increases labor time and cost.
Homes with extensive peeling, cracking, or deteriorated paint require much more prep work — scraping, sanding, caulking, and priming — which can represent 40-60% of total project labor.
Wood lap siding, cedar shingles, fiber cement (HardiePlank), stucco, and vinyl each require different prep techniques, products, and application methods. Some materials require more coats or specialized primers.
A single siding color with matching trim is the most efficient. Multiple body colors, contrasting trim, detailed millwork, and decorative elements require additional masking, cutting in, and paint changes.
Tall peaks, steep rooflines, second-story soffits, and areas requiring scaffolding or lift equipment add labor time and equipment costs.
Damaged or rotted trim, fascia, or siding discovered during prep needs to be repaired or replaced before painting. Rot repair costs vary from minor patching to full board replacement.
These are the real-world projects we see most often from Boise homeowners:
A 1,900-square-foot 1920s Craftsman with original fir lap siding, detailed trim, and a deep front porch with decorative columns. The prep process begins with a thorough soft-wash power washing to remove mildew, dust, and chalked paint residue, followed by a two-week drying period before any paint is applied. All soft wood is treated with wood hardener, loose paint is scraped to bare wood, and bare areas are spot-primed with an oil-based primer. All nail holes and cracks are filled with exterior spackle, all trim-to-siding joints are re-caulked with 50-year paintable caulk, and all previously painted surfaces are lightly sanded for adhesion. The topcoat system uses Sherwin-Williams Duration Exterior in a body color, trim color, and porch floor paint specifically selected for UV resistance. This is the most demanding exterior project type in Boise, and the most rewarding — a properly painted North End Craftsman holds its value and its appearance for 8 to 12 years.
A 1990-built stucco-finish home in west Boise with hairline thermal cracking throughout the south and west elevations — the predictable result of 30-plus years of Boise's temperature cycling. The prep process involves power washing, allowing full drying, and then applying an elastomeric bridging primer to the cracked areas before topcoating with an elastomeric or high-elasticity exterior paint. Standard exterior latex paints are not appropriate for stucco in Boise because they cannot bridge the thermal cracks that will re-open with each season; elastomeric products are formulated specifically to flex across these cracks and maintain a waterproof film. Color selection for stucco in Boise should favor lighter tones on south and west exposures to minimize heat absorption and thermal stress.
A 2019-built Harris Ranch home with a rear cedar deck and cedar horizontal fence that have weathered through five Boise summers without any protective coating, resulting in gray oxidation, UV checking, and early surface checking in the wood. The prep process involves pressure washing, deck brightener application, and a full dry cycle before staining. A semi-transparent penetrating stain (Defy Extreme or TWP 1500 series) is applied by brush and back-rolled to ensure full penetration into the open wood grain. This is one of the most requested project types in Boise's newer neighborhoods, where cedar decks are nearly universal and homeowners are realizing that Boise's UV intensity requires much more frequent maintenance than the same wood products in the Pacific Northwest.
A 2008-built southeast Boise home preparing for sale at $575,000 with original builder-applied exterior paint that has chalked, faded significantly on the south and west elevations, and begun to show cracking around windows and at corner boards. The project scope includes full power washing, caulk inspection and replacement at all joints and penetrations, spot priming of any bare areas, and two coats of Sherwin-Williams Duration Exterior in a freshened version of the original color scheme — keeping the home recognizable to neighbors while presenting a visibly refreshed curb appeal. This is the most common exterior painting scenario in southeast Boise, where the 2005–2015 build vintage means original paint systems are reaching the end of their useful life in volume.
A 1965 Bench bungalow where the body paint is in acceptable condition but the trim, window frames, garage door, and front door have peeled and faded to the point of hurting curb appeal. A targeted refresh of just the trim and accent elements — rather than a full repaint — is often the highest-ROI exterior project for Bench homes at the $300,000–$400,000 price point. The trim areas are scraped, sanded, primed, and topcoated in Benjamin Moore Aura Exterior, with the front door receiving a full prep-sand-prime-topcoat treatment in a bold accent color (iron red, deep navy, or forest green are popular in this neighborhood) that transforms the home's street presence at a fraction of the cost of a full repaint.

Solution: We scrape all loose paint to a firm edge, sand transitions smooth, apply bonding primer, and build up new paint film from a solid substrate — ensuring long-term adhesion.
Solution: We use premium exterior paints with UV-resistant pigments and fade-resistant technology specifically rated for high-altitude, high-UV environments like the Treasure Valley.
Solution: We remove failed caulk, clean the joints, and apply premium flexible exterior caulk that can handle Idaho's temperature range from -10°F to 110°F without cracking or separating.
Solution: Power washing removes existing mildew, and premium exterior paints with built-in mildewcide prevent regrowth. Proper surface preparation ensures the mildew-resistant coating adheres properly.
Solution: We identify and repair or replace rotted wood before painting. Minor rot can be treated with wood hardener and filled with exterior wood filler; significant rot requires board replacement.

Boise has a semi-arid, four-season climate with hot, dry summers (90-105°F), cold winters (15-35°F), and low annual precipitation. This climate directly affects material choices, construction scheduling, and long-term durability of remodeling work.
Exterior materials must handle dramatic temperature swings. Windows need strong thermal performance. Interior comfort depends on insulation quality and HVAC sizing.
Wood materials can dry, shrink, and crack. Hardwood floors may develop gaps in winter. Bathroom ventilation is still critical because bathrooms create localized high-humidity environments.
Exterior tile, concrete, and masonry must handle freezing and thawing without cracking. Foundation work has specific frost-depth requirements in the Boise area.
Exterior paint, siding, and stain fade faster under constant UV. South-facing and west-facing surfaces require UV-resistant materials and more frequent maintenance.
Foundation and exterior work is best scheduled March through November. Interior remodeling can happen year-round. Winter concrete pours require special cold-weather precautions.
Boise's most historic and walkable neighborhood, with tree-lined streets, Craftsman bungalows, Tudor revivals, and mid-century homes dating from 1900 to 1960. The North End Historic District adds design review requirements for exterior work.
Common projects in North End:
A mix of established 1970s-1990s homes and newer master-planned developments like Harris Ranch. Homes range from mid-century ranch-style to modern custom builds with foothills views.
Common projects in Southeast Boise / Harris Ranch:
An elevated neighborhood south of downtown with a mix of post-war homes from the 1940s-1970s and newer infill construction. Known for its views and access to the Greenbelt.
Common projects in Boise Bench:
A large area with subdivisions spanning from the 1980s through the 2010s. Many homes are builder-grade with standard finishes that homeowners upgrade as the homes age.
Common projects in West Boise:
Every Boise neighborhood has different housing stock, homeowner priorities, and project considerations. Here is what exterior painting looks like in each area:

Here are the design trends we see most often in Boise exterior painting projects:
Boise's housing market has appreciated significantly over the past decade, with median home values rising from approximately $180,000 in 2015 to over $450,000 in recent years. This appreciation makes remodeling an increasingly attractive investment — homeowners can invest $30,000-80,000 in a kitchen or bathroom remodel and see it reflected in their property value. The competitive market also means that updated, well-maintained homes sell faster and for higher prices than comparable homes with outdated finishes.

Avoid these common pitfalls Boise homeowners encounter with exterior painting projects:
Better approach: In Boise's generally low-humidity environment, homeowners and contractors often assume that siding dries quickly after power washing and can be painted within a day or two. This is a dangerous assumption for wood siding in particular — while the surface may feel dry to the touch within 24 hours, moisture deep in the wood fibers can persist for 4 to 7 days, and paint applied over moisture-laden wood will peel within one to two seasons as the trapped moisture works its way out. Iron Crest always allows a minimum of 3 business days between power washing and primer application on wood siding, extending to 5 to 7 days if the washing was particularly deep or if there are known areas of previous moisture intrusion.
Better approach: Interior paints lack the UV stabilizers, fungicides, and elasticity additives required for exterior performance, and will typically fail — fading, chalking, cracking — within one to two Boise summers when applied outdoors. The cost savings compared to a proper exterior product are entirely consumed by accelerated repainting costs. Even on protected surfaces like a covered porch ceiling or a north-facing garage wall that rarely sees direct sun, the moisture exposure and temperature cycling of exterior conditions require exterior-rated products. There are no legitimate exceptions to this rule for permanent exterior surfaces in Boise.
Better approach: Caulk failure at window perimeters, corner board joints, and trim-to-siding gaps is one of the most common sources of moisture intrusion and subsequent paint failure in Boise homes. Boise's extreme temperature cycling — from 15°F to 105°F annually — stresses caulk joints beyond the elasticity limits of most standard caulk products within 5 to 10 years. Before any exterior repainting project, every caulk joint on the home should be inspected; failed, cracked, or separated caulk should be fully removed and replaced with a high-quality paintable caulk with a 50-year warranty before any topcoat is applied. Adding new paint over failed caulk is cosmetic only — the moisture intrusion continues and will drive paint failure at that joint within one to two seasons.
Better approach: Dark exterior colors — charcoal, black, deep navy, dark forest green — have become fashionable in Boise's design market, and they can look stunning on the right home. However, dark colors on south and west exposures in Boise absorb dramatically more solar heat than lighter alternatives, driving surface temperatures to 140°F–160°F on peak summer days. These temperatures accelerate paint binder breakdown, cause thermal cycling stress in wood substrates, and can in extreme cases cause wood movement that opens seams and caulk joints prematurely. If you choose a dark body color for your Boise home, specify a heat-reflective formulation, accept a shorter repainting interval (potentially 5 to 7 years versus 8 to 10 for lighter colors), and ensure the prep and product quality is at its highest to maximize longevity.
Better approach: Boise's 2,730-foot elevation and 300-plus sunny days create UV exposure levels that invalidate the performance expectations of standard exterior paint products designed for lower-elevation, cloudier markets. A contractor who recommends a mid-grade exterior paint because "it's good enough for this area" is not accounting for the real performance data of exterior paint systems in Boise's climate. Ask any contractor bidding your exterior project specifically which products they're proposing and why those products are appropriate for Boise's UV conditions. If the answer is a mid-grade product like Sherwin-Williams SuperPaint or Benjamin Moore Regal Select without a specific justification, it's a sign the contractor is optimizing for their margin rather than your home's protection.
On a typical Boise home with wood siding and a quality paint system (Sherwin-Williams Duration or Benjamin Moore Aura), south- and west-facing elevations typically need repainting every 6 to 9 years, while north- and east-facing elevations can go 10 to 12 years between repaints. Budget paint products on south exposures may show significant fading, chalking, and cracking within 3 to 5 years under Boise's UV intensity. Stucco homes with elastomeric coatings often achieve 10-plus-year intervals between repaints. The most reliable indicator that repainting is needed: run your hand across the surface and check whether it comes away with a chalky white residue — this chalking is the paint binder breaking down and is a sign the protective film is near the end of its life.
From a purely practical standpoint, lighter and medium-toned colors perform better on Boise's south and west exposures because they reflect more solar radiation, resulting in lower surface temperatures and reduced thermal cycling stress on the paint film. Very dark colors — charcoal, black, deep navy — can reach surface temperatures of 140°F to 160°F on south-facing Boise walls in July, which accelerates paint breakdown and can cause substrate damage in extreme cases. That said, dark colors are achievable in Boise with the right product selection: Sherwin-Williams Emerald Exterior includes a heat-reflective formulation in dark colors that significantly reduces solar heat gain. The current Boise design market favors warm greiges and creamy whites for body colors, with deep charcoal, iron black, or soft black as trim accents — a combination that provides strong curb appeal while keeping the large surface areas (body) in lighter, more UV-resilient tones.
Yes — thorough preparation of wood siding on a North End home is the most important determinant of how long the new paint job will last. The prep sequence for original wood siding in good condition: soft-wash power washing, allow minimum 2–3 days to dry fully (wet wood will cause paint adhesion failure), scrape all loose paint to a firm edge, sand rough areas, fill all holes and cracks with exterior spackle, re-caulk all trim joints and penetrations with 50-year paintable caulk, spot-prime all bare wood with oil-based primer, and lightly scuff all previously painted surfaces for adhesion. For siding with significant deterioration — soft spots, deep UV checking, widespread delamination of old paint layers — the prep process is more involved and may include wood hardener application, board replacement, and potentially a full-surface prime coat before topcoating. Shortcuts in prep on North End wood siding are always more expensive in the long run than doing it properly the first time.
Stucco repainting in Boise is technically within the DIY range for experienced homeowners willing to invest in the right materials and techniques, but the most common DIY mistake — applying standard latex paint over thermally cracked stucco without elastomeric primer — results in a finish that looks good for one to two years and then shows the same cracking pattern even more prominently as the paint tears across the re-opened cracks. The professional approach uses elastomeric primer formulated to bridge cracks up to 1/16 inch wide, followed by an elastomeric or high-solids acrylic topcoat that moves with the stucco through Boise's thermal cycles. If you choose to DIY, budget for Sherwin-Williams Loxon elastomeric primer and either their Conflex or Elastomeric coating — the materials are more expensive than standard exterior products but the performance difference in Boise's climate is substantial.
The optimal exterior painting window in Boise runs from late April through mid-October, with May, June, September, and early October representing the best combination of temperature range, lower UV peak intensity, and reduced wind. July and August are the busiest painting months and are perfectly acceptable temperature-wise, but the extreme afternoon heat requires scheduling application on south and west surfaces for morning hours. Avoid exterior painting during Boise's winter months (November through March) — not because rain is a major risk, as Boise averages less than 12 inches of precipitation annually, but because nighttime temperatures regularly drop below the minimum application temperature for latex paints, and moisture condensation on cold surfaces prevents proper adhesion even when daytime conditions seem acceptable. The ideal conditions for exterior painting in Boise: air temperature 55°F–85°F, surface temperature below 100°F, no rain in the 24-hour forecast, and relative humidity between 30 and 70 percent.
A properly prepped and painted exterior using premium products should last 8-12 years in the Boise area. South- and west-facing walls may show wear sooner due to intense UV exposure. Quality surface preparation is the single biggest factor in paint longevity.
The ideal window for exterior painting in Boise is May through September, when temperatures are consistently above 50°F, humidity is low, and rain is infrequent. Early spring and late fall are possible but require careful weather monitoring.
A full exterior repaint for a typical single-story home in the Treasure Valley runs $4,000-8,000. Two-story homes typically cost $7,000-14,000. Costs vary based on home size, surface condition, prep requirements, and paint quality.
Yes. Power washing removes dirt, mildew, chalking paint, and debris that would prevent new paint from adhering properly. We power wash all exterior surfaces before scraping, sanding, and priming.
Yes. Fiber cement siding accepts paint very well and is one of the best substrates for exterior painting. We use 100% acrylic exterior paint that bonds to the cementitious surface and provides long-lasting color and protection.
If your siding is structurally sound and the surface condition allows for proper prep, repainting is significantly more cost-effective than residing. If siding is rotted, warped, or damaged beyond repair, replacement may be the better long-term investment.
We apply two coats of premium exterior paint over properly prepped and primed surfaces. Bare wood areas receive a coat of primer plus two finish coats. Two coats ensure proper mil thickness, UV protection, and long-term durability.
