Dry Rot & Water Damage Repair in Nampa, ID
Canyon County's hub, where agricultural roots meet fast growth
Nampa's century-deep housing mix means rot shows up in different forms block by block — original wood lap on early-1900s downtown homes, aging hardboard and T1-11 across the Midland and Karcher subdivision belt, and worn trim everywhere in between. Canyon County's dry wind and field dust pack into failed caulk joints and tired window weatherstripping, and once water gets past them the arid air keeps the decay quiet until the framing goes soft. Iron Crest Exteriors probes for the soft spots, follows the moisture to where it's actually entering, and cuts rotted sheathing and framing back to sound wood before correcting the flashing and re-establishing the weather barrier. Patching over wet substrate only buys a season, and we'd rather fix it once.

Our process
How dry rot & water damage repair works in Nampa
- 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.
Every Nampa job includes pulling any permit Canyon County requires and a full clean-up — we leave your home tight, weather-sealed, and looking sharp.
Working in Nampa
Canyon County's hub, where agricultural roots meet fast growth
Nampa is the largest city in Canyon County and the metro's second-largest overall, with deep agricultural roots, an older downtown, and farm ground stretching toward Lake Lowell. The housing stock spans a full century — early 1900s downtown homes with original wood siding, mid-century ranches with hardboard and aluminum, sprawling 1980s–1990s subdivisions, and newer construction filling in on the edges.
Nampa's wide range of housing vintages means siding and window conditions vary dramatically block to block — pre-1980 homes may still carry original wood siding and aluminum windows, while 1990s subdivisions are now into vinyl replacement age. Dry Canyon County winds, blowing field dust, and hot, exposed summers accelerate wear on any exterior that isn't properly sealed and maintained.

Dry Rot & Water Damage Repair in Nampa — FAQs
My older Nampa home near downtown has crumbling trim — is the wall behind it rotted too?
Crumbling trim is often the warning sign, not the whole problem. On Nampa's early-1900s downtown homes, deteriorated trim usually means water has been getting past it for a while, and the sheathing and framing directly behind frequently show decay once we open the area up. Dust-packed caulk joints common on Canyon County's windy valley floor make that intrusion worse. We start by probing behind the failing trim, trace where the water is entering, and repair back to sound material rather than just replacing the trim and trapping the moisture.
Which parts of Nampa do you serve?
All of them — from downtown Nampa to Karcher and throughout Canyon County. We'll come to your Nampa home for a free estimate.
Do you work outside Nampa, too?
We do — along with Nampa, we regularly handle dry rot & water damage repair in nearby Caldwell, Meridian, Middleton, Kuna and across the wider Treasure Valley. If you're near Lake Lowell, you're well inside our service area.
What's the site like after the work is done in Nampa?
Spotless. We finish every Nampa project by clearing out old materials and debris, so your Canyon County property is left clean and protected.
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.
