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.
Bargain paint over thin prep can fail in three years here. A proper system honestly applied runs 8–12 years on siding and 5–7 on the sunniest trim.
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.
Prep is the invisible half of the job. It's also the half that decides whether the visible half lasts.
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.
Winter and early-spring estimates get first pick of summer dates. Late callers get what's left.

What Our Customers Say
"Hilltop was outstanding to work with - Daniel was incredibly responsive, they did our interior walls and kitchen cabinet painting project on time (actually it was done early) and on budget, the quality of the work was excellent, and the places where we had requests for little fixes were taken care of literally the next day."
"We had a great experience with Hilltop painting! They do an excellent job preparing the house by cleaning, sanding and caulking wherever needed. A special shout-out to Mat, who was detail oriented and wanted to make sure we were happy with the results!"
"Hilltop and Andres team was top notch. They were professional, efficient and walked us through the process day by day. We had eight different colors in the interior of our home and they transformed it within a week and had a quick quote to finish turn around."
