Crawlspace Pipe Insulation

Protect pipes from freezing and save hot-water energy with properly sized, sealed insulation designed for crawlspace conditions.

Signs You Need Crawlspace Pipe Insulation

Cold snaps in SW Washington can expose under-insulated pipes to risk. Proper insulation avoids burst lines and improves hot-water efficiency.

Risk of burst pipes in extreme cold

Pipe insulation protects against bursting, reducing costly repairs and water damage.

Condensation forming on cold water pipes

Pipe insulation reduces condensation, helping prevent moisture damage and mold growth.

Bare or uninsulated pipes in the crawlspace

Pipe insulation increases energy efficiency by keeping water in pipes warmer.

Step 1

Assessment of pipe runs

Step 2

Cut, fit, and wrap pipes with fiberglass

Step 3

Maintain access to valves and cleanouts

We match thickness to pipe diameter and exposure; thicker insulation for lines near vents/exterior walls.
It reduces heat loss in the lines, so water stays hotter between uses—often improving perceived wait times.
We insulate around, not over, operable valves to preserve access and function.
On cold lines, insulation helps reduce sweating in humid conditions.
Some jurisdictions require certain piping to be insulated; we'll advise based on your home.
