A vapor barrier is the best thing for reducing crawlspace moisture and mold remediation, it also reduces energy costs as well as amount of cold air, dust and dirt entering your home. Crawl spaces below your home contain dirt floors which are generally damp. Water may easily access the space, and the added moisture increases the risk of mildew, mold, insects, rust, and rot in your home. Moisture directly impacts the humidity level of your home, making it hotter or cooler than it should be. You may have to run your air conditioner or furnace longer to compensate for these higher humidity levels, leading to your HVAC system or furnace running for too long as it tries to manage the temperature in your home. Sealing your crawl space with a vapor barrier it helps to reduce your energy costs by reducing the time that your air systems are running. Water and moisture can seep through walls and the dirt floor underneath your home. As moisture and humidity increases in a crawl space, the dark and damp environment spreads moisture and promotes the growth of mold and mildew. When you add a crawl space vapor barrier, it deters moisture from entering your home and prevents damage to the structure of your home caused by rotting wood, rusted metal, and damaged drywall. Sealing your crawl space with a vapor barrier allows it to stay dry and keeps the hazardous fumes caused by mold away from your family’s lungs.
To encapsulate a crawlspace we install a vapor barrier which is a 15mm moisture-proof plastic placed throughout the entire crawlspace floor and sealed to the inner walls of the foundation using expanding air seal foam. we then use a nail gun equipped with masonry nails and place wood blocks along the inner wall and nail them in place to ensure a sturdy air tight encapsulation. Once completed we proceed to close off all open-air vents in the crawlspace that were in place to release moisture from the dirt floor under the house. With a vapor barrier in place you no longer need open air crawlspace vents. To close off the vents we use rigid foam which will help mediate the hot and cold air flow from your crawlspace.
Crawlspace Exhaust Fan
We then install a quiet exhaust fan in the crawlspace to efficiently ventilate the crawlspace. This prevents condensation water issues in your home.
