One of the surest causes of frozen water lines under your house is open crawlspace vent holes also known as building vents. You may have to cut through drywall to fully expose the pipe and be able to apply insulation. Foundation vents are designed to improve the airflow under a house helping to maintain healthy humidity levels and air quality in your crawl spaces. Up in the attic clean the ceiling surface around each fixture slit the cover to accommodate the electrical cable and place the cover over the fixture.

Start by cutting away the caulking around the vent on the siding with a utility knife remove any screws and unclamp the duct leading to the dryer. Now it will be safe to heap insulation onto that spot. The vent will have a nail line marked on it. Apply the sealant around the cable and along the edge of the cover where it rests on the ceiling.

Secure the insulation with hvac duct tape. Track the exhaust pipe from your dryer until it leaves the house. You can buy special ridge cap shingles for laminated shingles like we show here or cut your own ridge cap from three tab shingles the shingle packaging will have directions. Cover the pipe in two to three inches of fiberglass insulation.

Slide the old vent out of the wall slip in the new one and reattach it to the duct. Step 1 wrap pipe in insulation.
