If your home is one of the 26 million built over a crawlspace, it could be costing you money. Vented crawlspaces let in moisture, causing damp and increasing energy bills. Crawlspace encapsulation solves the problem.
Lots of older homes – and up to 20% of new ones – were built over a crawlspace. It was once thought important to vent them, so these types of homes always had an air vent included. Newer scientific understanding has shown this assumption to be false.
Rather than improving air quality, they worsen it by letting in the damp. This has led more authorities to mandate crawlspace encapsulation in their states.
Vented Crawlspaces and Health Risks
Vented crawlspaces cause mold. Mold spores can be breathed in, where they irritate the lungs and trigger asthma, allergies and pneumonia. Babies are at special risk and, in rare cases, reported to have stopped breathing due to household mold.
Vents also allow more insects and even rats into the home. Dropping particles are inhaled, introducing e-Coli bacteria that can cause stomach bugs.
External pollution from traffic fumes can also enter the home through a crawlspace vent.
Vented Crawlspaces and Bills
Cold air that comes through the vent makes the floors in the home feel chilly. In the warmer months, the circulation of hot air makes the whole house harder to air condition. Both factors make a house with a crawlspace more expensive to heat and keep cool.
Residents with a crawlspace spend at least $28 more on their monthly electric bill.
Encapsulation is the Answer
Crawlspace services here in Indianapolis can encapsulate (seal off) the space to prevent moisture and unwanted guests from getting in. This is done by assessing the area, treating for damp and mold, adding waterproof coverings to the floor and adding an airtight cover to the vent.
A HVAC system can then be put in to reduce humidity and provide heat and cooling. If this isn’t possible, you can place a dehumidifier instead.
Crawlspaces make millions of U.S homes damp, and they affect indoor air quality. Getting the space encapsulated can improve health and lower bills at the same time.
