Siding Repair & Rot Restoration · Bellingham, WA
A soft spot on a Bellingham wall is rarely just siding — bay weather pushes water behind failed boards, and the rot spreads in the framing where you can't see it. We open the wall, restore the structure, and rebuild the exterior so it stays fixed.

Wind-driven rain off Bellingham Bay doesn't fall on walls — it's pushed into them, sideways, through every failed seam, cracked board, and unsealed penetration. Once water is behind the siding it can't dry out, and the sheathing and framing start to rot silently. Shaded lots from Sehome to Lake Whatcom compound it: moss holds moisture against joints year-round.
That's why painting over a soft spot, caulking a gap, or swapping one board usually fails within a couple of winters — the water source and the rotten structure are still there. Real rot restoration means opening the wall to sound material, rebuilding the framing and sheathing, correcting the flashing detail that let water in, and only then re-siding the patch.
And when the damage is limited, a repair is genuinely the right call — we do them all the time, and we'll tell you when it's enough. When rot shows on multiple elevations of an older home, we'll show you the photos and the math on why a full re-side costs less than chasing failures wall by wall.
We find the true extent of the rot — it's always bigger than the visible spot — and document it before quoting.
Siding and sheathing come off until we reach solid wood. No sealing rot inside the wall.
Framing and sheathing restored, then the flashing or barrier failure that let water in gets corrected — the part quick fixes skip.
New siding matched to your existing profile and color so the repair doesn't show from the street.
Matching your existing siding profile is part of the job — lap reveals, shingle patterns, and trim details blended so the repair doesn't announce itself from the street.
No good-better-best games — every project gets the full scope, spelled out line by line in your bid.

Verified Google review"Working with Siding Vault for our small exterior siding repair was a great experience. Michael was extremely responsive before, during, and after the job was done. The crew took advantage of good weather and put in extra hours to complete the job in one day (vs 2 as estimated). Minor additional items were found by the crew and repaired without adders. I would highly recommend Michael and his crew if you need siding repairs done."
Verified Google review"Michael is so great with communication, and I appreciate him being able to explain any concern I had. Oscar, the on-site manager, makes sure everything gets done correctly every step of the way. My house looks so adorable, and I get compliments from my neighbors saying it looks so nice. I would recommend them for their fair prices and good work. The photos of my before and after are on the Siding Vault website."
