Consider adding home weatherization to your summer to-do list. Typically considered during winter months, weatherizing your home provides comfort and energy savings year-round. It’s important during the summer months when air systems work overtime.
According to energystar.gov, a home with insufficient insulation and air leaks wastes more than 20% of the energy used to heat or cool it. Fortunately, most weatherization projects are easy to 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 tiny cracks and gaps around the frame. Do a quick visual inspection. If you can see any daylight around the frame or the windows rattle easily, you likely have air leaks. Also, check for any small cracks around the frame.
If you suspect you have leaky windows and plan to apply new caulk, be sure to remove the old caulk and clean the area well 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. If you have leftover caulk, use it to seal those areas.
Another effective but simple weatherization project is installing weatherstripping around exterior doors. The most common types of weatherstripping are V-channel, felt, and foam tape. To choose the best type for your home, consider temperature fluctuations and weather exposure. Most homeowners opt for felt or foam tape. Both options are easy to install but will 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. Door sweeps are available in aluminum, plastic, vinyl, and felt options.
Weatherstripping can also be installed around windows, typically to the sides of a double-hung or sliding window or around the window sash.
If you’re unsure how to install weatherstripping or apply caulk, check out trusted websites like Lowes.com or energy.gov for step-by-step instructions and video tutorials.
Another way to improve comfort in your home is by adding insulation. While this is a more costly project and requires a professional’s help, it’s an effective way to decrease heat flow, which impacts energy use in winter and summer months. Older homes may need additional insulation to either replace older materials or meet newer efficiency standards. Contact a qualified installation specialist if you suspect your home’s insulation levels are inadequate.
In addition to saving energy, air sealing can help you 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.
