Exterior Trim Painting in Boise, ID

Sharp Lines That Hold Up Through Idaho's Seasons

Your trim does more than frame your windows and doors. Gaps at caulk joints let moisture in, peeling fascia boards signal paint failure, and sun-bleached window casings can drag down your whole exterior even when the siding looks fine. Five Star Painting of Boise handles exterior trim painting for homes across Boise and the Treasure Valley, using products formulated for Idaho's wide temperature range and high UV load. Every project is backed by the Neighborly Done Right Promise® and comes with a flat-rate estimate before work begins. Check out our Boise painting page to see our full exterior service lineup.

What Goes Into Exterior Trim Painting Done Right


Exterior trim includes more surfaces than most people realize: window casings and sills, door frames and surrounds, fascia boards along your roofline, soffits under your eaves, corner boards, belly bands, garage door trim, and any exterior decorative molding. Boise homes built during the 1980s and 1990s construction boom often used finger-jointed pine for trim. That material gaps at the joints as Idaho's dry summer air pulls moisture from the wood, and once those gaps open, water gets in during winter rain and snowmelt.

Good prep takes more time than painting itself. We scrape and sand all loose or flaking areas down to a firm surface, then caulk every gap with exterior-grade paintable caulk. We pay special attention to the joint between window casings and siding, since Boise's December-to-March freeze-thaw cycle cracks caulk lines and pulls paint apart at that junction. Prime any bare wood with an oil-based or shellac primer before applying the finish coat.

Brush application is the right method for trim. Rolling leaves excess texture and makes it hard to keep window and door edges clean. Apply two finish coats after the prep and primer are fully cured, with adequate dry time between coats. During Boise's summer heat, we avoid painting in direct afternoon sun above 90 degrees because paint skins over before it bonds properly.

Most exterior trim performs best with 100% acrylic latex in a semi-gloss or satin sheen. Semi-gloss reflects UV better than flat finishes and holds up to cleaning without scrubbing off the surface. For door frames and window surrounds with heavy daily contact, a urethane-fortified trim enamel adds the film hardness you need without yellowing. Sheen and color choices get discussed before the estimate is finalized.

Why Choose Five Star Painting of Boise

Our painters work in Boise year-round and know how this climate affects exterior coatings. Temperatures swing well over 70 degrees between a January cold snap and a July heat wave, and that range beats up paint systems hard. We choose products formulated for those conditions, schedule work to avoid temperatures that compromise adhesion, and provide a complete line-item estimate so you can see exactly where the price comes from before anything starts.

Five Star Painting of Boise serves the entire Treasure Valley, including Meridian, Eagle, Nampa, Caldwell, Kuna, Star, Garden City, and Middleton. Every project is covered by the Neighborly Done Right Promise®. If the work isn't right, we come back and correct it. Our painters are background-checked, uniformed, and leave the job site clean at the end of each workday. Flat-rate pricing means the estimate and the invoice match.

Color consultation is available before painting starts, since trim colors read differently outdoors than on a paint chip. Your painter can walk you through how sheen levels and color values read in Boise's bright outdoor light before you commit.

    Picking Harmonious Wall Color and Floor Combinations

    While we can all appreciate a beautifully decorated room, what really ties it all together is the combination of colors that work in harmony to create the perfect look and feel. One aspect of achieving the right color combination that is sometimes overlooked is choosing the perfect wall color to suit your flooring, which can affect the overall aesthetic of your space.

    Ultimately, selecting the right wall color to compliment your floor will depend on the style of the room, its purpose and function, and your existing furniture and décor.

    Thankfully, the experts at your local Five Star Painting can help you narrow down the options to choose the best floor and wall color combination for your space.

    The Right Way to Remove Ceiling Water Stains and Restore Your Home

    Ceiling water stains often appear as unsightly brown or yellowish marks that detract from the overall aesthetics of a room. These stains are typically caused by water leaks or excessive moisture, and if left untreated, they can lead to further damage and even mold growth.

    Fortunately, there are several methods for effective ceiling water stain removal to restore their beauty.

    Can You Paint Pressure-Treated Wood?

    Although you can paint pressure-treated wood, stain will usually adhere better than paint does. The primary reason is that the preservatives in pressure-treated wood make it harder for the paint to bond to the wooden surface. But don’t worry, it’s still possible to paint your deck or fence if you take the proper precautions.

    Keep in mind that wood that has been pressure-treated needs to be completely dry so it can absorb the paint or stain.

    For a long-lasting and great-looking finish, first evaluate the wood’s moisture content, then apply the correct stain or primer and paint.
