Exterior Painting Cost in Boise

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 a porch floor paint rated for foot traffic. This is the most demanding exterior project type in Boise, and the most rewarding — done properly, the difference shows on the sunny elevations years later, which is where a shortcut job gives itself away first.

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. Cedar decks are common in Boise's newer neighborhoods, and the maintenance interval here is shorter than the same wood products need in wetter, cloudier markets because the controlling variable is sun rather than rain.

A 2008-built southeast Boise home preparing for sale, 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 most cost-effective exterior project for a Bench home whose body coating still has life in it. 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.
