If your home has a crawl space and it isn’t properly insulated, it could be costing you money each month. A space that isn’t insulated properly means that the outside air is entering your home, and your air conditioner and heating unit are working harder than they need to be. An uninsulated space also means that the quality of the air in your home is lower than it should be. And you may be encouraging mice and other pests if your crawl space isn’t properly insulated; once they are in that space it’s easier than you might think for them to get inside your home. Expect to pay between around $1,800 and $4,000 to properly insulate the space. If you need crawl space insulation Tacoma contractors are able to carry out this essential work, to ensure better air quality and lower energy bills.
