How To Insulate Pipes in a Crawlspace

Inspecting insulation on a residential crawlspace water pipe.

There are a lot of things that we associate with winter from snow angels and skiing to the holiday season. But there are some things that we also associate with winter that we’d rather not think of, like clearing snow off our vehicles every day… or freezing pipes bursting in our crawlspace. Freezing water pipes can make your plumbing useless at the least, and can result in a burst pipe at worst, leaving your crawlspace wet or even flooded. The best way to prevent any wintery complications with your crawlspace piping is with preparation. Let’s dive into how you can be ready for the next winter with proper water pipe crawlspace insulation and other preparation methods:

1. Insulate Your Pipes Against Exposure

Outdoor air during the winter can be blisteringly cold. Whether your pipes are outside the house or inside a leaky crawlspace, you’ll want your pipes to be protected against exterior winter temperatures and that accompanying wind chill. Use materials such as pipe-wraps and form pipe sleeves to cover your pipes and protect them. By insulating your water pipes, you will help lower the chances of them freezing and/or bursting.

2. Insulate Any Pipe Gaps and Openings in Your Crawlspace

Any cracks or openings in your crawlspace that allow for exterior air to flow in should be sealed. The cold winter air can quickly cool the air in your crawlspace and freeze the water pipes within. By sealing the cracks with caulk, you can keep the cold air out while keeping the warm air in.

You should also address any air gaps around your water pipes. Gaps where the pipes exit through your exterior wall, should be addressed. Insulate those pipe gaps with expanding foam to help insulate the pipes and prevent cold outside air from freezing the water pipes. It will also prevent those outside air from coming into your crawlspace to affect the water pipes within.

3. Sealing Your Crawlspace

Along with checking for cracks and opening to the exterior, it is important to seal the rest of your crawlspace to help maintain warm temperatures and to keep more of that cold air out. Consider covering your crawlspace with foam pieces that can cover the walls as well as the floors. Keep those foam pieces in place with tape or another fastener, so that they stay in place.

4. Use Heating Tapes

Another solution to keeping your water pipes warm is to use heating tapes, but this should be installed by a professional expert to ensure your safety and a proper installation.

5. Keep the Heat on and Keep the Temperature Consistent

There may be times where you may think about letting the temperature drop in your house to save on the heating bills. But whether you’re doing it because you’re taking a trip, or because a certain part of the day has a different temperature, it’s better to keep your home temperatures steady. Been maintaining a consistent internal temperature, your pipes will keep flowing and there will be less chance of a temperature change causing your pipes to freeze and burst.

Preparation is Key and Saves You Trouble!
