Why clean your crawl space?

While many homeowners do not access their crawl space regularly or use it for storage, what happens in this space can have a large impact on the rest of the home. If you have a vented crawl space, you can count on 40% of the air in your home coming from your crawl space. Anything in that air — including mold spores, odors, and humidity — are all brought up into your home. Cleaning your crawl space will eliminate a highly significant source of allergens in your home, while also creating a healthier environment.

At Clarke Basement Systems, we've seen the absolute worst that crawl spaces can offer -- and we've tackled it all! Here are just a few photos our experts have taken from the field:

What causes a crawl space to affect a home's health and energy efficiency?

The crawl space is out of sight and out of mind for many homeowners, but what happens there can have a huge impact on your home. Here are a few key areas to focus on.

  • Crawl space ventilation: A vented crawl space allows cold air to enter in the winter and humid air to enter in the summer. This air will affect your home's temperature and force your HVAC system to work harder, especially if your ducts are in the crawl space, which in turn will raise heating and cooling costs.
  • Water issues: Outside air in the crawl space also leads to condensation, which brings excess moisture in the crawl space. A crawl space can also be affected by water leaking in through the walls or a dirt floor. Moisture in the crawl space will lead to mold growth, pests, foul odors, and structural damage.
  • Structural damage: The crawl space is full of materials that provide a breeding ground for mold, including the wood joists. If you have sagging or bouncy floors above the crawl space, you could have wood rot or structural damage.

Clean, seal, & insulate your crawl space

Our crawl space liner, energy efficient dehumidifier, and other products will create a healthier, more energy efficient space in your home. Mold, rot, and mildew will be controlled, and rodent and insect infestations will be discouraged. The structural elements of your crawl space will be protected, and our durable, non-organic insulation won't support further mold growth.

Sealing a crawl space also creates dry, usable space that looks great and provides extra storage in the home. Below are just a few pictures of crawl spaces our experts have sealed.
