Crawl Space Insulation
Lower Bills, Warmer Floors, More Comfortable Home
Old or damaged crawl space insulation is silently draining your energy budget and making your home uncomfortable. We replace it with high-performance insulation built for the Pacific Northwest — with results you'll feel immediately.
What Is Crawl Space Insulation — and Why Does It Matter?
Crawl space insulation is the thermal barrier installed between the cold ground under your home and the living space above it. When properly installed, it keeps warm air inside during winter and cool air inside during summer — directly improving energy efficiency and comfort.
Over time, crawl space insulation can become damaged by moisture, pest activity, or simply age. Wet or compressed insulation loses most of its effectiveness and can actually trap moisture against your floor joists — accelerating rot and mold growth.
At House Crawlers, we don't just add new insulation on top of old. We remove the damaged material, inspect for underlying issues, and install the right insulation for your crawl space — correctly, from scratch.

Common Questions About Insulation
-
Common signs: cold floors with the heat running, unreasonably high heating bills, sagging or fallen batts in the crawl space, musty odors, or evidence of pest activity in the insulation.
-
We typically install R-19 to R-30 in crawl spaces, depending on floor joist depth and energy performance goals. We'll recommend the right R-value during your inspection.
-
Sometimes — but if your vapor barrier is damaged or missing, replacing it first is essential. Installing new insulation over a failing barrier wastes the investment.
-
Most insulation jobs are completed in 1 to 2 days, including removal of the old material.
-
Yes. We back our installation with a workmanship warranty, plus the manufacturer's warranty on the insulation material.
