Canyon County, Idaho
Crawl space repair in Caldwell
Caldwell is the Canyon County seat, with older homes around downtown and the College of Idaho and newer neighborhoods growing out from there. Indian Creek runs through downtown, and the Boise River runs along the north side of town.
In the older homes, the problems tend to be age: original insulation, little or no barrier. In the newer ones, it’s more often water.
What we run into in Caldwell
Original insulation
Old batts that have sagged, fallen, or been taken over by mice.
Low ground near water
Homes near Indian Creek or toward the river can see higher groundwater in summer.
Landlord jobs
Rental properties that need a straight scope, photos, and the work done without a lot of back and forth.
A recent Caldwell job
[A real Caldwell job: neighborhood, what you found, what you did, one photo]Why it’s dry in March and wet in August.
From roughly April to October the canals run full for irrigation. In parts of Caldwell, that pushes the water table up, and it comes into the crawl space from underneath, not through the walls.
Exact dates vary by irrigation district and by year. So does how much it affects a given street.
What that means for you: a crawl space that looks fine at a spring inspection can have standing water by midsummer. If you put a new barrier down without handling that, the water ends up trapped under the plastic.
If yours is wet in summer and dry in winter, it’s probably groundwater, not a leak. That’s the first thing we check. Water removal and sump pumps
What we do in Caldwell
Selling a Caldwell home and the inspector flagged the crawl space? Here’s how home-sale repairs work.
Water removal and sump pumps
Pump it out, find where it comes from, and give it a permanent way out.
Call when: Standing water, wet dirt, or a pump that runs all summer.
Vapor barrier replacement
Pull the old plastic, fix what’s under it, and put down a barrier that’s sealed and fastened.
Call when: Torn, thin, or missing plastic, or an inspector’s note about the barrier.
Crawl space encapsulation
Sealed liner on the ground and walls, vents closed, and the air dried.
Call when: Repeat moisture, ductwork in the crawl space, or you want it done once.
Mold remediation
Clean and treat the framing, then fix whatever kept it wet.
Call when: Dark staining or growth on joists and subfloor, or a musty smell.
Crawl space insulation
New insulation under the floor or on the walls, with old, wet, or damaged insulation pulled out first.
Call when: Cold floors, no insulation at all, or batts hanging down, wet, or torn up by rodents.
