Cracked, bubbling, or rotting siding in western Washington usually means water is already getting behind it. Here are the signs to check.
Siding fails slowly and quietly. By the time it is visibly falling apart, water has usually been getting behind it for a season or two. Here is what to look for before that happens.
Paint bubbling in the same spots after repainting is not a paint problem. It usually means moisture is pushing through from behind the siding. Repainting over it buys one season at most.
Press firmly on the siding in a few places, especially near the bottom of walls and under windows. Softness, sponginess, or a hollow crunch means rot has started. Once rot reaches the sheathing behind, the repair gets significantly more expensive.
Small cracks are common with age and not always urgent. Warping, buckling, or gaps that open wider each year mean the material has lost structural integrity and is letting water in.
In our climate, siding that touches or nearly touches soil absorbs moisture constantly and rots from the bottom up. It also invites termites and carpenter ants. This is one of the most common defects we find on older Everett homes.
Moss and mildew happen in the Northwest and are not automatically a problem. But dark staining that returns quickly after cleaning, or fungus growing on the siding itself, suggests the material is staying wet.
Failing siding often means failing weather barrier behind it. If the house feels draftier or heating costs have crept up without another explanation, the building envelope may be compromised.
Stains on interior walls or ceilings near exterior walls, especially after heavy rain, mean water is already making it through. This moves from "maintenance" into "repair it now" territory.
If you find one or two of these signs, get it looked at before winter. Siding that is repaired in October costs far less than sheathing and framing that has to be replaced in February.
A proper inspection looks behind the siding, not just at it. Anyone who quotes a full re-side without checking for rot behind the existing material is guessing.
Fiber cement lasts 30 to 50 years, engineered wood 20 to 30 with maintenance, vinyl 20 to 30. Installation quality matters more than the material's rated lifespan.
Often yes. If damage is localized, replacing a section is much cheaper than a full re-side. If the damage is widespread or behind most of the wall, partial repair is throwing money at a bigger problem.
Not fully, but it is one of the higher-return exterior projects and it prevents much more expensive rot repair.
