Unlock Comfort & Savings
Weatherizing your home provides energy savings and comfort year-round, especially during summer months when your air conditioner is working overtime.
A home with insufficient insulation and air leaks wastes more than 20% of the energy used to heat or cool the home, according to energystar.gov. Fortunately, most weatherization projects are DIY and can be completed in a day.
The simplest and most cost-effective weatherization strategies include air sealing around windows and exterior doors.
If you have older windows, odds are you have air escaping through cracks and gaps around the frame. If you can see daylight around the frame or if the windows rattle easily, you likely have air leaks. Also, check for small cracks around the frame that may not be visible with sunlight.
If you suspect you have leaky windows and plan to apply new caulk, be sure to remove the old caulk and clean the area before application. Caulking materials vary in strength and properties, but you’ll likely need a half-cartridge per window.
Silicone caulk is a popular choice and can also be used to seal joints between bathroom and kitchen fixtures.
Another effective but simple weatherization project is installing weatherstripping around exterior doors. The most common types of weatherstripping options are V-channel, felt, and foam tape.
Choose the best for your home by considering temperature fluctuations and weather exposure. Most homeowners opt for felt or foam tape. Both are easy to install but need to be replaced every couple of years, depending on wear and tear. Weatherstripping should be installed around the top and sides of the door.
If you see daylight around the bottom of an exterior door, consider installing a door sweep in addition to weatherstripping.
Weatherstripping can also be installed around windows.
Another way to improve comfort in your home is with insulation. While this is a more costly project and requires a professional’s help, it’s an effective way to decrease heat flow.
Older homes may need additional insulation to replace older materials or meet newer efficiency standards. Contact a qualified installation specialist if you suspect insulation levels are inadequate.
The best way to identify air leaks in your home is a blower door test. A blower door test helps determine how airtight your home is and identify air leaks.
In addition to saving energy, air sealing can help avoid moisture control issues, improve indoor air quality, and extend the life of your heating and cooling system. Weatherize your home to unlock year-round comfort and savings on monthly energy costs.
