How Often Should You Repaint a House in Western Washington?
The short answer: exterior paint lasts seven to ten years in the Puget Sound region — but that number assumes maintenance. Washing the house every two years to kill moss and mildew, and catching split caulking before water gets behind it, is the difference between the top and bottom of that range. Poor prep on the original job shortens it dramatically.
Everyone knows the Pacific Northwest is hard on houses. What's less obvious is which part of the weather does the damage, and how much control a homeowner actually has over it. After 30 years of painting in this region, here's how I explain it.
Moss and mildew, not rain
The instinct is to blame rain. I don't:
The moss and the mildew is what really deteriorates the house the most. And then just poor prep — if somebody else does it and doesn't prep it well, that moisture is going to get in the home. That's going to be what's going to have issues with the paint.
Moisture matters, but as a delivery mechanism for biological growth and as something that gets behind the paint through gaps that should have been sealed. The rain itself, hitting cured paint on a well-prepped wall, is not what wears a house out.
Which is why my single strongest maintenance recommendation isn't about paint at all.
Wash the house every two years
We really recommend our customers have us come out to do a pressure washing at least every two years.
Not a rinse — a bleach wash system that actually kills the mold and mildew rather than relocating it. And the wash is only half the value. The other half is that somebody knowledgeable is walking your entire exterior at close range on a regular schedule:
While they're doing that, they will scan all the water intrusion areas, all their caulking joints and everything, to make sure that there's no areas of rot or caulking that's split that needs to get replaced.
This matters more than the paint job itself:
Those items are going to give so many years — not just for the paint on the exterior of it, but to make sure that there's no water that comes into the home that damages the home in a large way.
Split caulking around a window is a fifteen-minute fix if you catch it. It's rot repair if you don't. The most common problem I find on Tacoma and Federal Way homes is exactly this: rotted wood from deferred maintenance, traced back to bad caulking and missing flashing. The full season-by-season plan is in our exterior paint maintenance calendar.
The midpoint touch-up that buys you years
There's a maintenance move most homeowners never hear about. Around the halfway point of the paint's life, one or two walls are usually much worse than the rest — the ones taking the weather.
At that halfway point, we can come in — usually we'll have one or two really, really worn walls from the weather — and do a quick repaint of a couple walls, so they can get a little bit more life out of their home.
Repainting two walls is a fraction of the cost of repainting a house, and it can push a full repaint out by years. Whether anyone offers you this depends entirely on whether your painter is thinking about your house or about their next full-house sale.
Sun matters more than salt water
Homeowners near the water in Gig Harbor tend to assume salt air is their main enemy. It's a factor, but I rank something else higher:
The salt water will affect it. A bigger part, I think, is just exposure to sun.
The two exposures fail in opposite directions:
- Heavy shade → more moisture retention, and more mold and moss growth.
- Heavy sun → the paint dries out faster, and the color goes. That sun just beating on that paint — the colors that they pick matter. Certain pigments in your paint will fade faster than others.
That last point has a practical consequence at color-selection time. If you're choosing a deep or saturated color for a wall that takes direct afternoon sun, the pigment you pick and the product grade you pick determine how it looks in year six. For deep base colors we move up to Sherwin-Williams Emerald specifically so the color doesn't fade out.
When better paint is the wrong choice
Here's the piece of experience that separates someone who's painted for 30 years from someone reading a product label. Premium paint is not automatically the right answer:
Older houses, sometimes you don't want to use the best quality — because it can actually bite too much into the paint and actually take it off. Lesser quality paints are sometimes better, because they can breathe better.
A hundred-year-old house with brand-new siding gets the high-end product. That same house with its original siding, where old paint is being lead-prepped or encapsulated, needs something that will let the assembly breathe and won't attack what's underneath it.
It all depends on which home we're doing.
If a contractor quotes you their most expensive paint for every house regardless of what the house is, that's not a premium service. It's a product they sell.
Can you paint in winter here?
Mostly, yes — which surprises people.
As long as it's above 35 degrees, we can paint, and it's not raining. A lot of the paint stores have updated and they've got new formulas of paint that you can paint pretty much right before it rains. It's going to rain an hour after — I could paint a home, and then an hour later it rains, and the paint's going to be just fine.
Modern exterior formulas have largely solved the narrow-window problem that used to make Northwest exterior painting a summer-only proposition. Staining is more weather-sensitive and gets scheduled more carefully.
Practically, this means you have more scheduling flexibility than you probably assume, and you aren't necessarily competing with every other homeowner for the same eight-week window.
What a full exterior job actually involves
The seven-to-ten-year number assumes the job was done properly the first time. Here's what "properly" looks like on our exterior painting jobs:
- Preparation by the homeowner — personal effects moved away from the house, and trees and shrubs cut back from the walls.
- Wash with a bleach system that kills mold and mildew, then a full rinse.
- Scrape all loose paint once the house is dry.
- Caulking audit — anything split or shrunk gets cut out and reapplied.
- Water-intrusion check at every door, window, and corner board.
- Surface leveling — on older homes with many layers of paint, a peel-bonding primer and sanding at the joints so the finish looks right.
- Oil primer on all bare wood.
- Mask lights and windows; remove what comes down.
- Spray the body of the house.
- De-mask and hand-brush all trim.
- Accent colors last — doors, garage doors, bump-outs.
- Final walkthrough with the homeowner, then a one-year labor warranty.
Steps two through seven are where the seven-to-ten years is won or lost. They're also, conveniently, the steps that are easiest to skip and hardest for a homeowner to audit after the fact.
Prep is our big thing, because prep is the base of all that we do.
What cheap exterior jobs skip
The corners most commonly cut, in order:
- Rinsing instead of bleach-washing. It might clean some of the mold and mildew off the home, but it can leave some — where then it just gets embedded between the layers of paint. You've now sealed a living organism under your new finish.
- Not enough caulking. The direct cause of the water intrusion that causes the rot.
- Less prep generally. Someone can quickly come in and not do as much prep and just paint a home. And it might look nice, but there's going to be areas that are going to be seen.
- Lower-grade paint.
The through-line: all four are invisible on the day the crew leaves. They surface in year two or three, well after final payment. How to choose a painting company covers the questions that expose them before you sign.
Frequently asked questions
How long does exterior paint last in Western Washington?
Seven to ten years with good maintenance. Without it, meaningfully less — poor prep on the original job is the fastest way to the short end of that range.
How often should I pressure wash my house?
Every two years. Use a bleach-based wash that kills mold and mildew rather than a plain rinse, and treat it as an inspection opportunity for caulking and rot.
Does living near the water in Gig Harbor mean I need to repaint more often?
Salt air is a factor, but sun exposure generally does more. Shaded walls fight moisture and moss; sun-facing walls fade and dry out. Both are manageable with regular washing and the right product for the exposure.
Can you paint a house in the winter in Washington?
Yes, as long as it's above 35 degrees and not actively raining. Current exterior paint formulas tolerate rain shortly after application, which opens up far more of the calendar than most homeowners expect.
Is expensive paint always better?
No. On older homes with original siding, a premium product can bond too aggressively and pull off what's underneath, and a more breathable mid-grade paint performs better. The right product depends on the house.
What's the most common exterior problem you find on Tacoma homes?
Rotted wood from deferred maintenance — usually the result of failed caulking or missing flashing that let water in over several years.
