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 New Plymouth, Idaho is a battle against an intense high-desert sun, a wide annual temperature swing, and a housing stock dominated by old wood siding — and winning it depends almost entirely on preparation. New Plymouth was platted in 1896 as an irrigation colony, the Plymouth Society of Chicago and William E. Smythe arranging a horseshoe of two streets around a mile-long Boulevard park. The homes ringing that horseshoe and dotting the surrounding farm acreage are largely wood-sided: colony-era farmhouses with original lap and shiplap siding carrying a century of coatings, mid-century ranches in wood or early manufactured siding, and a modest minority of newer builds. At roughly 2,257 feet of elevation in an open river valley, these exteriors take punishing UV exposure, freeze-thaw cycling, wind-driven grit from surrounding agricultural land, and the moisture stress of irrigated farm ground. With a 2020 Census population of 1,494 in a community where homes are kept for generations and their condition is noticed, exterior painting here is genuine envelope protection, not curb-appeal cosmetics. Iron Crest Remodel (Iron Crest Remodeling Group LLC, Idaho RCE-6681702) approaches New Plymouth exteriors with preparation-first discipline and, on pre-1978 homes, the EPA RRP lead-safe practices that exterior scraping and sanding legally require.
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.
New Plymouth 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 New Plymouth:
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.
New Plymouth's housing is older and more layered than the suburban Treasure Valley: a 1896 colony-era and pre-1940 farmhouse core, a deep 1950s–1970s ranch layer, and a modest post-2000 subdivision minority. Most homes sit over vented crawlspaces.
Original colony and early-twentieth-century farmhouses around The Boulevard. Plaster-and-lath interiors, original wood siding and single-pane sash, galvanized supply lines, undersized electrical service, and crawlspace subfloors. Pre-1978 lead-paint and pre-1980 asbestos handling required.
Ranches and ramblers built as irrigated agriculture matured. Sound framing, aging copper plumbing, marginal panels, single-pane or early aluminum windows, thin insulation, and closed floor plans. Pre-1978/1980 environmental rules still apply.
Post-2000 builds such as Harvest Creek. Modern PEX plumbing, adequate electrical, and builder-grade finishes on tighter lots. No environmental-testing requirements.
Material selection affects the look, durability, and cost of your exterior painting. Here are the most popular options we install in New Plymouth:
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

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 New Plymouth:
| 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. |
New Plymouth range: $4,500–$9,000 – $28,000–$60,000
Most New Plymouth projects: $11,000–$26,000
New Plymouth exterior painting costs are governed by siding condition, prep extent, and lead-safe requirements rather than by paint grade. The low range covers a smaller newer or well-maintained home with sound siding needing wash, minor prep, and two coats. The high range covers a large colony-era farmhouse with extensive scraping, wood repair, full re-caulking, multiple stories, detailed trim, and complete EPA RRP lead-safe containment and disposal. The average band reflects the typical New Plymouth job: a wood-sided mid-century ranch or moderate older home requiring substantial surface preparation — scraping, sanding, spot-priming bare wood, rot repair, caulking — plus lead-safe practices on pre-1978 surfaces, and a UV-durable coating system. The dominant local cost drivers are preparation labor on old, sun-degraded wood siding (the single largest variable), mandatory EPA RRP containment and disposal on pre-1978 homes, and the multi-elevation full-sun exposure that demands premium coatings and meticulous south- and west-facing prep. Quick wash-and-spray jobs on sound newer homes are not the typical New Plymouth project; prep-heavy restoration of old wood siding is.
The final cost of your exterior painting in New Plymouth 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 New Plymouth homeowners:
The signature New Plymouth exterior project: a pre-1940 wood-sided farmhouse on or near the Boulevard with a century of coatings, widespread checking and peeling, localized rot at end grain and near grade, and lead-based paint. Scope is preparation-led — lead-safe containment, scraping and sanding to sound substrate, wood repair and replacement of failed boards, end-grain and bare-wood priming, full re-caulking, and a UV-durable two-coat system, with HEPA cleanup and compliant disposal throughout. The visible result is a transformed historic home; the durability lives in the prep that DIY and low-bid crews skip.
New Plymouth's 1950s–1970s ranches in wood or early manufactured siding typically need a full repaint addressing sun-faded, chalked south and west elevations, checked siding, failed caulk, and minor rot. Scope includes pressure washing, scraping and sanding failed areas, spot-priming, caulk replacement, and a UV-resistant finish system, with lead-safe practices on pre-1978 homes. South and west elevations get the most intensive prep because that is where New Plymouth's sun does its damage first.
A recurring New Plymouth pattern: a home whose north and east sides are sound while the south and west elevations have failed years early under full valley sun — chalking, peeling, and exposed gray wood. Scope concentrates restoration on the failed elevations — aggressive scraping, sanding, priming exposed wood, repair — then coats the whole home for uniformity. Addressing only the failed sides while color-matching the whole envelope is a cost-effective, locally specific approach.
New Plymouth's agricultural properties carry shops, barns, and outbuildings that benefit from protective coating against the same UV and moisture stress as the house. Scope ranges from wood-siding restoration on older structures to industrial-grade coating systems on metal shops, with preparation matched to the substrate. Maintaining these structures' envelopes protects significant property value on working farm parcels.
Post-2000 Harvest Creek and similar homes — typically fiber-cement or modern manufactured siding — need straightforward maintenance recoating: wash, minor prep, caulk touch-up, and two coats of a UV-durable system before the original builder finish degrades. No lead, minimal substrate repair, predictable scope. The key local value is recoating on a UV-driven schedule before failure rather than after.
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.

The 1896 colony heart: two horseshoe streets around the mile-long Boulevard park with original irrigation ditches. Predominantly colony-era and pre-1940 wood-sided farmhouses on generous original acre tracts; strong period character and a protected streetscape.
Common projects in The Boulevard / Historic Horseshoe Core:
Grid streets around and behind the horseshoe filled with 1950s–1970s ranches and ramblers built as the irrigated farm economy matured. Sound framing, aging copper and marginal panels, closed floor plans, on municipal water and sewer.
Common projects in Mid-Century Ranch Streets (In-Town):
Working farm and ranch acreage surrounding the town, outside city limits and under Payette County jurisdiction. Homes range from century-old farmsteads to modern custom builds, typically on private wells and septic systems.
Common projects in Agricultural Fringe / Rural Acreage:
Post-2000 subdivision pockets representing New Plymouth's modern housing minority. Modern PEX plumbing, adequate panels, and builder-grade finishes on tighter lots; no environmental-testing requirements.
Common projects in Harvest Creek / Newer Subdivisions:
Every New Plymouth 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 New Plymouth exterior painting projects:
New Plymouth and Payette County home values have appreciated well above their historic norms; local market median list prices reached roughly $485,000 with an average around $449,000 in early 2026 (Redfin), against a longer-run median home value near $277,500. Inventory is limited in a small market with homes selling in roughly 70 days. With trading up locally often impractical, long-tenure, multi-generational families predominantly renovate to keep — making durable, do-it-once work the local standard and a strong resale signal in a closely-watched market.
Avoid these common pitfalls New Plymouth homeowners encounter with exterior painting projects:
Better approach: New Plymouth's UV-degraded wood siding must be scraped to sound substrate, with bare and end-grain wood primed, rot repaired, and joints re-caulked before topcoat. Coating over unprepared old siding traps failure beneath fresh paint and peels within a few years in this climate. Preparation, not paint brand, determines coating life here.
Better approach: Most older New Plymouth exteriors have lead paint, and uncontrolled scraping contaminates soil and air illegally. Lead-safe exterior work requires ground containment, controlled removal, HEPA practices, and compliant disposal. This is mandatory federal practice on pre-1978 homes and must be in the scope, not skipped.
Better approach: Lesser coatings chalk and fade on New Plymouth's south and west elevations within a few years. A premium UV- and fade-resistant 100% acrylic system with elastomeric flexibility to track wood movement is the baseline here. The coating-grade premium is small against the labor cost of an early redo.
Better approach: Cold-snap frost during cure and peak-summer heat flashing on sun-loaded elevations both compromise the finish. Schedule within the valley's spring-to-fall window and sequence sun-exposed elevations for favorable conditions. Timing is part of durability in this climate, not an afterthought.
Better approach: New Plymouth's wide thermal cycling defeats low-grade caulk within a season or two, and failed caulk is the moisture entry point that causes peeling and rot. Specify a high-grade elastomeric exterior sealant at all joints, trim, and penetrations. It is a minor material cost protecting the entire system.
New Plymouth's open valley setting at elevation delivers intense ultraviolet exposure, and south and west elevations take the brunt of it for the full day with little tree cover on most properties. UV breaks down coatings, so those sides chalk, fade, and peel years ahead of the shaded north and east elevations. The durable approach is heavier preparation on the sun-exposed sides — full scraping and priming of degraded wood — and a premium UV-resistant coating system, then coating the whole home for uniformity. Recoating on a UV-driven schedule before failure is far cheaper than restoring rotted siding after.
Yes. Most pre-1978 New Plymouth homes — the Boulevard core and many ranches — have lead-based exterior paint, and scraping or sanding it is regulated under the EPA RRP rule with stringent exterior requirements: ground containment, controlled removal, HEPA practices, and compliant disposal to prevent soil contamination. We perform lead-safe-compliant exterior work as standard practice on pre-1978 homes. Uncontrolled DIY exterior scraping on these homes is both illegal and an environmental and health hazard.
It depends almost entirely on preparation and coating quality, not luck. A properly prepped wood-sided home — scraped to sound substrate, bare and end-grain wood primed, rot repaired, re-caulked with elastomeric sealant, and finished with a premium UV-resistant acrylic system — performs well even under New Plymouth's harsh valley sun, with sun-exposed elevations the limiting factor. A low-prep job over chalked, checked old siding can fail in just a few years here. The investment is in preparation; that is what buys longevity in this climate.
The high-desert climate constrains the window to roughly spring through fall, avoiding winter and shoulder-season frost risk during cure and managing peak-summer heat so coatings on sun-loaded elevations do not flash. We schedule around the valley's favorable window and sequence sun-exposed elevations for the conditions that let the coating bond and cure properly. Timing is part of durability here, not just convenience.
On New Plymouth's agricultural properties it is often worthwhile. Shops, barns, and outbuildings face the same UV and moisture stress as the house and represent significant property value worth protecting. We match the system to the substrate — wood-siding restoration on older structures, industrial-grade coatings on metal shops. Coordinating outbuilding work with the house repaint is efficient and protects the whole property's envelope on one schedule.
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.
