Siding rarely fails overnight. Learn the paint-failure patterns, the awl test, and the specific spots where East Bay houses start rotting long before anyone notices.
Wood does not fail all at once. It gives you two or three seasons of warning, usually in places nobody looks: the back side of a fascia board, the bottom two inches of a corner trim, the shingle course right under a leaking gutter. Catch it there and it is a carpentry afternoon plus paint. Miss it and it becomes siding replacement, framing repair, and a much longer conversation. These are the signs we look for on East Bay houses.
Read the way the paint is failing
Different failures point at different causes. Alligatoring, that deep cracked pattern like reptile skin, usually means many old oil layers that have gone brittle, and in a pre-1978 house those layers often contain lead, so they get contained and wet-scraped rather than sanded dry. Blistering with bare wood underneath means water is pushing from behind. Peeling in clean sheets points to adhesion, often a coat applied over chalk or damp wood. Rust bleeding from nail heads means fasteners are wet more often than dry.
The awl test tells you what your eyes cannot
Take a small awl or a screwdriver and press it into suspect wood at a shallow angle. Sound wood resists and the tip barely marks it. If the point sinks a quarter inch with light pressure, the fiber is already gone and paint will not bring it back. We probe the usual suspects: sill noses, the bottom of casing where it meets the sill, butt joints in horizontal siding, rake and fascia ends, and anywhere a downspout splashes.
Warning signs worth acting on this year
- Caulk lines that have pulled away from one side of a joint, leaving a visible dark gap at window casings, corner boards, or siding butt joints.
- A moisture meter reading above eighteen percent on siding that has been dry for a week, which means water is arriving from somewhere other than the sky.
- Cupped, curled, or split shingles, especially on south and west walls where heat drives the movement hardest.
- Dark staining or soft, spongy wood behind gutters and at the ends of fascia boards, usually the first place a house rots.
Restoration is carpentry before it is paint. We cut out failed sections and let in new stock, use epoxy consolidant and filler where a profile is worth saving, prime every face and edge of new wood including the back before it goes up, and bed it in fresh sealant. None of that matters if the water source stays. Gutters, flashing, a kickout at the roof-wall intersection, grade against the foundation, and sprinklers hitting the siding all get fixed first.
The difference between restoration and replacement is usually a couple of rainy seasons. If you have seen any of these signs, get eyes on it before winter. Liquid-Culture does wood restoration and repair alongside exterior painting, so the carpentry and the coating are handled by the same crew and nothing falls between them.
