The Right System for Your Siding
Every siding fails differently in Sumas weather. Pick yours — the prep, primer, and coating change with it.
Cedar & Wood Siding
Sumas's classic — and its most demanding. Cedar moves with moisture, so the system has to breathe: oil or acrylic primer on bare wood, then two coats of 100% acrylic that flex through freeze-thaw.
What Exterior Painting Costs in Sumas
Sumas repaints run $5,000–$15,000, and where repair work remains from the flood years we itemize it separately so you can phase the spending. New siding from a rebuild usually just needs the right primer and product; older survivors need more prep first.
Either way the estimate is free and written, one line at a time.
Coatings Chosen for Sumas's Weather
Foothill rain and valley damp is what kills paint around Sumas, so it's what we spec against. That means 100% acrylic systems that breathe and flex through freeze-thaw, and elastomeric where hairline cracking calls for it.
Sumas homes that took water in the 2021 flood taught everyone here what trapped moisture does to a wall. Paint that cannot breathe peels from the inside out. A breathable acrylic system over dry, primed siding is how a repaint in this valley reaches ten years instead of three.
Prep Is Everything on Older Cedar Siding
Most of what we paint near Sumas is border-town homes, many rebuilt since the 2021 flood, and a lot of it predates 1978. That means lead-safe scraping and sanding from an EPA-certified firm, moss and mildew killed at the source, and bare wood spot-primed before color.
Houses rebuilt since the flood mostly need a clean surface and a careful moisture reading before any primer goes on. The older stock near the border crossing needs the opposite: patient scraping through decades of layers. Either way, the paint waits until the wood is ready.
Timing Around Whatcom County Weather
Dry siding and 50°F+ is the rule, which makes late spring through early fall the season in Sumas. Daily forecast checks decide which wall gets painted when.
The Sumas valley holds its damp later into spring than the coast does, so we trust the moisture meter over the calendar. Book early and you get a July slot when the siding is genuinely dry.

Border Town on the Flats: A Short History of Sumas
Nooksack people lived on this ground for thousands of years before Robert Johnson, the first permanent settler, arrived in 1872. The name Sumas means land without trees, or big flat opening, and it fits: the town sits on a broad floodplain that drains north to the Fraser.
Sumas City incorporated on June 18, 1891 as a railroad hub, and for a while it supplied the Mount Baker gold rush. The Sumas Roundup rodeo drew crowds in the early 1900s. Today the 24-hour port of entry at the north end of State Route 9 connects the town to Abbotsford, British Columbia, right across the line.
Water is the recurring story. Floods have been recorded since settlement, the November 1990 flood did millions in damage, and on November 15, 2021 about 85 percent of the homes in town were damaged and hundreds of people had to be rescued. Sumas has rebuilt a lot since, and we have painted a good share of it.
Outside, Sumas gets some of the county's hardest winters, and freeze-thaw cracks cheap paint. We wash, prime bare wood, seal, and use premium coatings so the siding sheds water instead of holding it.
