Because your crawl space has air vents and is in contact with the ground, it is exposed to outside elements. This could cause pipes in your crawl space to freeze during even a brief cold spell. It is important to take precautionary steps to protect your crawl space before temperatures dive. If not, you could end up with burst pipes.
Some of the most common quick fixes are incorrect and simply do not work. These fixes include closing the air vents, letting your faucets trickle, or wrapping vents and pipes. There are many reasons why these fixes do not work:
- Closing air vents can cause moisture buildup leading to possible mold and wood rot.
- Leaving the faucet running during a hard freeze can cause water buildup in pipes causing them to crack, split or become completely blocked off.
- Wrapping pipes and vents can be a bad idea. The condensation that comes with a humid climate can get trapped under the insulation and cause mold to grow.
The best solution is to insulate your crawl space to help maintain a consistent temperature in your crawl space. This reduces the likelihood of freezing pipes or condensation buildup and can help maintain a comfortable temperature inside your home.
