How much of the air in your home comes from your crawl space?

 How much of the air you breathe in your home comes from your crawl space? - Image 1

Have you ever considered what’s in the air you breathe in your home? While it’s weird to think about, but for homeowners in the Pacific Northwest, it should be top of mind.

Approximately 50% of air on the first floor of your home comes from your crawl space. That means any mold, unwanted odors, or whatever stray vermin may bring in to your crawl space is seeping into the air and parts of your home where your family spends quality time together.

How your crawl space affects your home

When warm air rises and leaks out of the upper levels of your home, new air replaces what has escaped, and that air comes from the lowest parts of a house.

If your crawl space has substantial water or if outdoor air comes in through vents, then your crawl space is prone to high humidity which will inevitably travel through the upper levels of your home. Mold growth also typically starts in your crawl space.

In short, your crawl space impacts the amount of humidity, condensation, and mold that could be seeping into your home.

How to solve your crawl space problems

Before you can resolve any problems with your air quality, you need to know if you have an issue! The only way to know what’s happening in your crawl space is to venture down there and check it out for yourself. Understandably, not many homeowners want to investigate a dirty, smelly crawl space, and if they do, they might not know what to look for.

Fortunately, you can gain peace of mind about your crawl space and home air quality with the help of TerraFirma. By setting up an appointment, an experienced and local System Design Specialist will come to your home and provide you with a free inspection of your crawl space. On that same day, you’ll receive a report from the System Design Specialist that will detail what they discovered in your crawl space, and what they recommend you should do to help improve your home’s air quality.
