When Is the Right Time to Paint Your Exterior in Portland and the surrounding area?
Posted on February 5, 2026
If you live in or near Portland, you already know the weather has a personality. Long, wet winters. Mild springs. Dry, golden summers that feel endless. And then—just when you get comfortable—rain again.
All of that matters a lot when it comes to exterior painting.
So how do you know when it’s actually time to repaint your home’s exterior in Portland? Let’s break it down—weather, warning signs, and timing that actually works in the Pacific Northwest.
1. PNW Weather Sets the Rules
Exterior paint doesn’t just need to look good—it needs time to cure. In our climate, moisture is the biggest factor working against you.
Ideal painting conditions:
- Dry weather (no rain for at least 24 hours after washing your home)
- Temperatures between 40°F and 85°F
- Low humidity (or at least not actively raining… which we’ll take as a win)
That’s why late spring through early fall—roughly May to September—is prime exterior painting season in Portland. Summer is king here, especially July and August, when rain finally gives us a break.
Painting outside of this window is possible, but it’s riskier. Moisture can cause paint to blister, peel, or fail prematurely. CertaPro Painters’ experts will consult with you about your home’s specific characteristics to balance the weather with your timing needs.
2. Signs It’s Time to Repaint (Even If You’d Rather Not)
Sometimes the calendar matters less than what your house is telling you. Watch for these common exterior red flags:
Peeling or Bubbling Paint
This is often caused by trapped moisture—very common in our damp climate. Once you see this, the paint has already failed.
Fading or Chalky Color
Overcast skies don’t prevent UV damage. If color looks washed out or leaves residue on your hand, the protective layer is breaking down.
Cracked Caulk or Exposed Wood
When paint stops sealing properly, moisture can get into siding and trim. Around Portland, that’s how rot starts.
Mold or Mildew Growth
Green or black streaks on siding aren’t just cosmetic. They’re a sign moisture is sticking around longer than it should.
If you’re seeing one or more of these, it’s probably time—regardless of whether you just painted “a few years ago.”
3. How Often Do Portland Homes Need Repainting?
Because of rain and humidity, exteriors around here usually need repainting more often than homes in drier climates.
Typical timelines:
- Wood siding: every 5–7 years
- Fiber cement (Hardie): 8–10 years
- Stucco or masonry: 10+ years (with maintenance)
South- and west-facing sides often fail first due to sun exposure, even here in the PNW.
4. The Best Time to Schedule (Hint: Don’t Wait Too Long)
Most homeowners aim for summer—and so do painting contractors. If you wait until June to start calling, you may already be late.
Smart move:
- Start planning in early spring
- Schedule painting for the earliest weather window that works for your home
- Lock in dates before everyone else realizes the rain has stopped
Bonus: spring inspections can catch small issues before they turn into expensive repairs.
5. Why Timing Matters More Here Than You Think
A properly timed paint job:
- Lasts longer
- Protects against moisture damage
- Prevents wood rot and siding failure
- Saves money long-term
A poorly timed one? You’ll be repainting again sooner than you’d like—and our winters are unforgiving to bad paint jobs.
Bottom Line
If you live in Gresham, Portland, Beaverton, Lake Oswego, Hillsboro, or the surrounding communities, exterior painting is all about working with the weather, not against it. Late spring through summer is ideal, but the real signal is the condition of your home. If paint is peeling, fading, or letting moisture in, it’s time—rain or shine.
If you want help deciding this year or next, or which areas need attention first, the experts at CertaPro Painters can help you think it through. Portland houses have their quirks—we’re happy to get into them.
