A quality exterior paint job on the Eastside should last 7-10 years. But "should" and "will" depend entirely on whether you maintain it. The Pacific Northwest's moisture cycling, moss growth, UV exposure, and freeze-thaw cycles are constantly attacking your paint. Simple annual maintenance can extend your paint job's life by 3-5 years — which at $5,000-$10,000 per repaint, represents significant savings.
Annual Spring Inspection (30 Minutes)
Every spring, walk your home's exterior with a critical eye. Check these five areas:
1. Caulk joints. Look at every seam around windows, doors, trim, and any penetration through the siding. Cracked, missing, or pulling-away caulk is an active water infiltration point. Repairing a $2 tube of caulk now prevents a $2,000 rot repair later.
2. Paint condition. Look for chalking (white powder when you rub the surface), peeling, cracking, or bubbling. Early-stage issues can be touched up. Advanced failure means a full repaint is coming soon.
3. Moss and algae. North-facing walls and areas under tree cover in Lynnwood, Bothell, and Lake Forest Park are prime targets. Moss holds moisture against the paint surface and accelerates degradation. Remove it promptly.
4. Gutters and downspouts. Overflowing gutters dump water directly onto painted siding and trim. Keep them clean and properly directed away from the house.
5. Vegetation contact. Trim back any bushes, trees, or vines touching painted surfaces. Plant contact traps moisture, promotes mildew, and physically abrades the paint film.
Annual Wash (One Afternoon)
Wash your home's exterior once a year. A garden hose with a car wash soap solution and a soft brush is sufficient — you don't need a pressure washer for maintenance washing. This removes dirt, pollen, spider webs, and early-stage mildew before they become embedded in the paint.
For areas with visible mildew or algae, use a solution of 1 part bleach to 3 parts water. Apply, let sit 10 minutes, and rinse thoroughly.
Touch-Up Protocol
When you find small areas of peeling or bare wood during your inspection, address them immediately. Scrape the loose paint, sand the edges smooth, apply primer to bare wood, and touch up with matching paint. Keep leftover paint from your last project stored in a cool, dry place with the lid sealed tight — it's good for 2-5 years.
A $20 touch-up today prevents a $5,000 section repaint tomorrow.
When Maintenance Isn't Enough
If your inspection reveals widespread chalking, cracking across multiple elevations, significant peeling, or rot in more than a few spots, it's time for a full repaint. Our exterior paint longevity guide covers the full timeline and signs to watch for.
