What about the gaps around electrical and plumbing penetrations between my crawl space and living space?

Posted by

Thanks for your question! There is little room for shortcuts in crawl spaces. Unfortunately, many people don’t think about the space much, but it really does matter to the overall health and comfort of your home. When it comes to crawl spaces, you’re right to sweat the small stuff. Attention to these seemingly small details can help you avoid big headaches later. Don’t ignore the gaps around electrical and plumbing penetrations between your crawl space and living space… seal them.

Why seal the gaps around plumbing and electrical penetrations between your crawl space and living space?

Ultimately, the comfort level of your home will depend on your ability to manage air flow. You want to have some control over how air is directed as well as where it stays, and where it goes. Closing gaps is an important home climate management strategy. When you take the time to seal around electrical and plumbing penetrations you will effectively prevent air from moving into the wall or living space from the crawl space. That means you won’t have to contend with outside air temperature working against whatever inside air temperature you are trying to maintain.

Seal gaps for more comfort and reduce heating/cooling costs.

Drafts caused by gaps force your heating and cooling system to work harder. That means higher environmental impact as well as higher energy costs. You will save more and protect the environment more overtime by making the initial investment to seal the gaps. You’ll be more comfortable, too. Unwanted air flow can dramatically impact temperature in your home living space. Seal gaps to avoid temperatures that are too hot or cold.
