Crawl space repair in Middleton
Middleton sits along the Boise River between Star and Caldwell. The old town core is small, and most of the growth has been new subdivisions on the farmland around it.
Much of that ground is low and close to the river, so seasonal groundwater is the first thing we look for under a Middleton house.
What we run into in Middleton
Low ground, high water
Homes on lower ground toward the river can see the water table come up in summer.
Sump pumps that can’t keep up
Undersized pumps or bad discharge lines that send the water right back toward the house.
New-build barriers
Thin plastic that was laid loose and never sealed to the walls.
A recent Middleton job
[A real Middleton 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 Middleton, 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 Middleton
Selling a Middleton 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.
