Basement & Crawl Space Insulation in Hutchinson, KS

Basement and crawl space insulation fixes cold floors and drafts that come from below. Many Hutchinson-area homes have basements, and nearly all have a rim joist, the wood band sitting on top of the foundation wall, that leaks air at every seam. In winter, cold air pours in there; in summer, warm humid air does.

Rim joists

Closed-cell foam seals and insulates the rim in one step. HomeGuide puts a rim joist foam job at about $2,000 to $2,500. It is one of the most noticeable upgrades for the money.

Basement walls

Poured and block foundation walls carry ground temperature into the basement. Closed-cell foam on the inside face insulates and slows vapor, and goes on before framing if you are finishing the space.

Crawl spaces

Crawl spaces under additions or older homes can be insulated at the walls with closed-cell foam, sealed at the rim and covered with a ground vapor barrier. HomeGuide lists encapsulation at $3 to $10 per square foot.

Water first

Foam is not waterproofing. If a basement leaks, grading, gutters or drainage need to be fixed first. We check before quoting.

Finishing a basement

If you plan to finish the basement, insulate the rim and walls before framing. We explain what covering the foam needs.

Older foundations

Older homes in Hutchinson and the railroad towns may have stone, brick or early block foundations. We check for loose mortar and water first. On a dry, sound wall, closed-cell foam follows the uneven surface.

Cold floors over garages

Rooms built over attached garages often have cold floors. Closed-cell foam in the garage ceiling fixes that and seals out fumes.

Ask each insulation company for linear feet of rim and square feet of wall, with foam thickness and price.
