When it’s time for crawl space insulation Tacoma residents have many companies ready to carry out this essential job. But just why is insulating your crawl space so important anyway? You’ll find you lose a lot of cool air and heat through the floor if you don’t insulate; this of course can waste energy and lead to higher energy bills. Insulation also means you’ll notice fewer cold spots and drafts in the rooms immediately above your crawl space. Insulating the space under your home can also help to keep bad moisture out; without insulating it, the space can attract moisture, dirt and dust, which can affect anyone with allergies or asthma in your home. As far as the cost of insulating this often overlooked space, expect to pay between $800 and several thousand dollars, depending on its size and the quality of materials used.
