Dry Rot & Water Damage Repair in the Treasure Valley
Stop the rot behind your siding
When siding starts failing, the real damage is often behind it: rotted sheathing, soft framing, crumbling trim, and decayed substrate caused by water that got past failed flashing, cracked caulk, or a worn-out weather barrier. Dry rot and water-damage repair fixes the structure, not just the surface — because new siding over wet, rotted wood fails just as fast as the old.
We open up the affected areas, trace the water to its source, and remove all rotted sheathing, framing, and trim back to sound, dry material. Then we re-establish proper flashing and drainage and install a fresh weather barrier before re-siding over a substrate that's actually capable of holding the new cladding. Skipping the source is the most common reason rot comes back.
Finding the true extent matters as much as the repair itself. Water travels, and rot is frequently wider than it looks from outside — concentrated around windows, at the base of walls, behind gutters, and at deck-to-wall connections. We probe, follow the moisture path, and document what we find before we commit to a scope, so there are no buried surprises.
This is the right service when you've got soft or spongy walls, persistent peeling paint, dark staining, a musty smell, or siding that flexes when pressed. We won't cover rot to make a wall look fixed; we'll show you what's there and repair it so the problem doesn't return.

Our process
How we handle dry rot & water damage repair
- 01
Moisture inspection
We probe for soft spots and trace the water path to find every affected area and the actual source of the intrusion — not just where the staining shows.
- 02
Open & remove rot
Siding comes off the affected zones and we remove all rotted sheathing, framing, and trim down to sound, dry material.
- 03
Correct the source
We fix the flashing, drainage, or sealing failure that let water in, because repairing rot without correcting the cause just resets the clock.
- 04
Rebuild structure & barrier
We replace damaged sheathing and framing, re-establish proper drainage, and install a fresh, correctly lapped weather-resistive barrier.
- 05
Re-side & finish
New siding goes back over the sound, dry wall, matched to the surrounding material, and we finish and clean the area.
In the Treasure Valley
Built for local homes & weather
Idaho's freeze-thaw cycle is hard on failed caulk and flashing — water gets into an open joint, freezes, and works it wider, so hidden rot around windows and at the bottoms of walls is common on older valley homes. The dry valley air can also mask it: there's no constant humidity to make staining obvious, so rot can advance quietly behind good-looking siding until a wall goes soft.
On HOA properties, the re-side portion of a rot repair still has to match approved color and profile, and we'll match as closely as the existing material allows. The structural repair itself is about getting the wall sound and dry.
Structural and substrate repair can fall under permit and inspection requirements depending on scope and jurisdiction. When the work reaches framing repair, we coordinate anything that needs to be inspected so it's documented properly.
Dry Rot & Water Damage Repair FAQs
How do I know if I have rot behind my siding?
Soft or spongy spots, peeling or bubbling paint, dark staining, a musty smell, siding that flexes when pressed, or trim that crumbles are common signs. In our dry climate it can advance quietly without obvious surface clues, so a probe-and-inspect visit is the way to confirm.
Will you find all the damage?
We trace the moisture path and open up affected areas to find the full extent, and we document what we find. Rot is often wider than it looks from outside because water travels, so we'd rather show you the true picture before repairing than discover more mid-job.
Can you just side over the rot?
No — and we won't. Covering rotted, wet substrate just hides a structural problem and the new siding fails over it. The rot has to be removed back to sound material and the moisture source corrected, or you're paying twice.
How do you stop it from coming back?
By fixing the cause, not just the symptom — correcting the failed flashing, drainage, or sealing that let water in, then rebuilding with a fresh, properly lapped weather barrier. Rot that returns almost always means the source was never addressed, which is exactly the step we don't skip.
What drives the cost?
How far the rot extends, how much sheathing and framing need replacing, access and height, the source repair, and the re-side scope are the main factors. Because much of it is only visible once siding is off, we inspect and document before quoting and flag the possibility of finding more.
