Insulation and Weatherization
Weatherize your home and start seeing savings
Poor insulation, drafty windows, unsealed doors—all of these things not only cause your home to leak heat, but also money.
Fortunately, there are multiple ways to improve your home’s energy efficiency, many of which are relatively inexpensive. You’ll enjoy a more comfortable home and reduce your energy bills at the same time.
Tips for weatherizing your home
Air leaks are the biggest energy wasters in the home. The good news is that it doesn’t cost much to seal them. Caulk, weather strip, and/or insulate around:
- Entrance doors
- Electrical outlets and switch plates on exterior walls
- Bathroom and kitchen exhaust fans
- Exterior hose connections, such as dryer exhausts
- Areas where ductwork, electrical wiring, or plumbing extends through floors, ceilings, or exterior walls
- Warm-air registers and water-heater and furnace flues
- New and replacement windows, or existing windows with cracked caulk
