One of the most common questions we get from Seattle-area homeowners is: how long will this last? It's a fair question — exterior painting is a significant investment, and the Pacific Northwest climate is uniquely challenging.
The Honest Answer: 7-10 Years with Quality Work
A properly done exterior paint job using premium materials should last 7-10 years in Western Washington — sometimes longer on protected surfaces, sometimes shorter on heavily exposed areas.
What Shortens Paint Life in Washington
Moisture is the #1 enemy. The Pacific Northwest gets 38+ inches of rain annually in the Seattle area, with the real damage often coming from moisture cycling — wet and dry cycles that cause wood to expand and contract, stressing the paint film.
Prep quality is the single biggest factor in longevity. Paint over a dirty, chalky, or poorly primed surface and it will fail early regardless of paint quality. We spend 40-60% of every exterior job on prep.
Signs It's Time to Repaint
Peeling, bubbling, or flaking paint. Chalking — white residue on your hand when you touch the siding. Fading or discoloration, especially on south-facing walls. Caulk cracking around windows and trim.
