Insulation questions, answered by experts

Spray foam has superior sealing properties, moisture resistance, and soundproofing capabilities compared to traditional insulation.

If you’re a savvy DIYer around the house, own the basic tools, and have enough time on your hands, you can definitely install fiberglass insulation yourself. Doing the work yourself will certainly keep overall insulation costs down. However, if you’re not confident in your handy skills around the house, call in a professional.

Insulation prevents heat transfer, which keeps your home cool in summer and warm in winter. Regulating the temperature in your home is not only more comfortable for you, but will lower your heating and cooling bills—it’s a win-win. Make sure to determine the correct amount of insulation to ensure it is enough for your home and climate.

Costs depend on the type of insulation, area to be covered, and labor, generally ranging from $1 to $4 per square foot.

Ductwork insulation in the crawl space is a simple add-on if you are hiring someone to insulate the entire crawl space already. Separately, it is only a few hours of work. The investment is nothing compared to the return since uninsulated ducts can lose up to 30% of their heating and cooling efficiency.
