Home Size and Number of Stories
high impactThe 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.

Surface Preparation Requirements
high impactHomes 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.

Siding Material

!!
Number of Colors and Trim Details

!!
Height and Access Challenges

Wood Rot Repair

The specific type of exterior painting project affects the budget significantly. Here are the most common project types in Nampa:
Full Exterior House Painting
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.
Trim, Fascia, and Soffit Painting
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.
Deck and Fence Staining
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.
Front Door and Garage Door Painting
High-impact refresh of entry and garage doors. Includes sanding, priming, and spray or brush application of durable exterior paint in your chosen color.
Exterior Staining (Wood Siding and Cedar)
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.
Nampa is Canyon County's largest city and one of the most diverse housing markets in the Treasure Valley. The city has homes dating from the early 1900s through brand-new construction, creating a wide range of remodeling opportunities. Nampa homeowners tend to prioritize practical, value-driven upgrades — functional kitchens, updated bathrooms, improved energy efficiency, and added living space. The lower median home price compared to Ada County cities means Nampa homeowners are often more budget-conscious, but they still want quality work that improves daily life and holds up over time. Canyon County's permit process is straightforward, and Nampa's Building Department is responsive to residential projects.
Nampa has the most diverse housing stock in Canyon County, spanning from early 1900s farmhouses and bungalows to brand-new subdivision homes. This diversity means every project has unique structural and system considerations.
Pre-1950 (Downtown, older neighborhoods)
Bungalows, farmhouses, and early-century homes with plaster walls, hardwood floors, and older plumbing and electrical systems. These homes need system upgrades alongside cosmetic updates.
1960s–1980s (Northwest Nampa, established neighborhoods)
Ranch homes and split-levels with original tile, carpet, and basic finishes. Plumbing is copper or early PEX. Electrical may need panel upgrades for modern kitchen and bathroom demands.
1990s–2010s (South Nampa, newer subdivisions)
Builder-grade subdivision homes with standard finishes. Similar to Meridian's housing stock — ready for finish upgrades as the homes age.
2015–present
New construction with modern systems and open floor plans. Homeowners upgrade finishes 3-5 years after purchase.
Nampa shares the Treasure Valley's semi-arid climate. Canyon County locations may be slightly warmer in summer and experience more wind than Ada County locations closer to the foothills.
Summer Heat
Nampa tends to run 2-3°F warmer than central Boise in summer. HVAC sizing and window quality matter for comfort and energy costs.
Agricultural Dust
Proximity to active farmland means more dust exposure for exterior surfaces. Durable, cleanable exterior finishes are preferred.
Freeze-Thaw
Same frost-depth and freeze-thaw considerations as Boise for foundations, exterior tile, and plumbing in exterior walls.

How long does exterior paint last in Boise?
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.
What is the best time of year to paint a house exterior in Idaho?
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.
How much does it cost to paint a house exterior in Boise?
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.
Do I need to power wash before painting?
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.
Can you paint fiber cement (HardiePlank) siding?
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.
Should I repaint or reside my home?
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.
How many coats of paint do you apply?
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.
Do you repair wood rot before painting?
Yes. We identify all rot during the prep phase and repair or replace damaged wood before any paint is applied. Painting over rot without repair leads to continued deterioration and premature paint failure.
