- Inspect the crawl space. Block or other solid crawl-space walls usually have openings that allow frigid air to flow through. Choose plywood, tin or other solid materials to cover openings. Secure them with wooden or metal stakes driven into the ground in front of them. Caulk cracks around faucet openings and all basement windows.
- Choose pipe insulation. Even 1/4 inch of newspaper wrapped around pipes provides some degree of insulation.
- Insulate both hot and cold water pipes in the crawl space. Make sure no part of the pipe is left exposed. Use duct or other recommended tape to cover seams where insulation pieces join.
- While inside the crawl space, check for areas where light is shining through. Caulk or cover these areas.
Things You Will Need
- Plywood or tin
- Metal or wooden stakes
- Pipe insulation
- Duct tape
- Box cutter or knife
- Many insulation products, such as foam pipe sleeves and heat tape, sell out quickly when freezing temperatures are predicted--so shop well before that time.
- If possible, have a helper who can hold a flashlight while you insulate pipes, or wear a hardhat with a light attached.
- Knee pads are a good investment when crawling into lower crawl spaces.
