Exterior paint is your home’s raincoat. In western Oregon, where siding and trim stay damp for much of the year, it works harder than almost anywhere in the country. The question most homeowners ask is simple: how often does it need to be redone? The honest answer is that it depends, and this guide explains what it depends on and how to tell when your house is due.
A realistic timeline
A quality exterior paint job on well-prepared surfaces commonly lasts somewhere in the range of seven to ten years, and sometimes longer on protected walls. In the Pacific Northwest, expect the shaded north and west sides, and surfaces that stay wet, to wear out sooner than sunny, sheltered ones. Preparation and the quality of the paint matter as much as the calendar. A rushed job on damp or dirty siding can start to fail in a few years, while a carefully prepped job often outlasts expectations.
What affects how long paint lasts
Several things set the clock. Surface preparation comes first: cleaning, scraping, sanding, priming bare wood and replacing failed caulk. Material matters, since wood, fiber cement and trim take paint differently. Exposure matters, with sun, rain, tree cover and sprinklers all shortening or extending the life of the finish. Color matters too, because very dark colors absorb more heat and can fade faster in direct sun. Finally, the product and application count, including the number of coats and the drying time between them.
Signs it is time to repaint
Look for peeling, bubbling or flaking paint, chalky residue that rubs off on your hand, fading or uneven color, cracked or missing caulk around windows, doors and trim, bare or gray wood, and mildew or algae that returns quickly after cleaning. Hairline cracks in the paint film at joints are an early warning, because they let moisture in behind the surface.
Why waiting can cost more
Paint is cheaper than carpentry. Once moisture gets behind failing paint, wood can swell, soften and rot, and then the job becomes siding and trim repair before any painting begins. Repainting a little early is often less expensive than repainting late, because there is less rot to repair and fewer coats are needed to restore the surface. If you already see soft spots, our dry rot repair service can fix them before the new paint goes on.
The best time of year to paint in Oregon
Paint needs dry surfaces and mild temperatures to cure properly. In the Willamette Valley that usually means the stretch from late spring through early fall, when rain is least likely and surfaces dry quickly. Booking early helps you get on the schedule, since the good weather window is also the busiest. Surfaces should be dry before painting, which is why we pressure-wash the day before and let the exterior dry.
Older homes and lead-safe practices
If your home was built before 1978, the existing paint may contain lead, and disturbing it requires certified, lead-safe work practices under federal rules. Salexx is an EPA Lead-Safe Certified Firm, which means we contain dust and clean up the way those rules require. If you are planning a DIY project on an older house, it is worth learning those rules first.
What a good paint job includes
A thorough exterior repaint starts with washing, then scraping and sanding loose paint, repairing damaged trim, priming bare spots, removing failed caulk and replacing it with a durable product, and finishing with a two-coat system. We use Sherwin-Williams products and look at your light, roof color and neighborhood when helping you choose colors. Our exterior painting service covers homes, fences, decks, sheds and other buildings across Newberg, Sherwood and the Portland metro, and it pairs well with siding projects when the surface needs more than paint.
