Save Energy by Fixing Basement Air Leaks

Your energy bills can be high for a number of reasons; maybe your thermostat needs reset, you need a new air filter, or you just need a maintenance visit. But there is one more issue that most homeowners don't think about. 

Basements can be a constant source of heat or cold air loss in both the summer and winter months, especially in older homes. If you have cracks or leaks in your basement, your HVAC system has to work harder to keep you comfortable, raising your energy bills.

Find the Leaks Locating air leaks can be a challenge, so the best way to find them is to hire a professional to conduct an energy audit. However, if you feel up to the task, check around the floor joists, foundation walls, ceiling, and insulation for obvious holes and cracks. Small cracks can be filled with caulking; for larger cracks or gaps in the insulation, use a spray foam.

The most important part of the basement to insulate are the sections of the wall that sit above ground level. They are often pure concrete, which is not a good material for insulation. The exposure to the outside air allows a good amount of air to seep-in or escape.
