Leaks in walls, window sills, and doors are all easy escape routes for cold air in the summer and warm air in winter to swap space with the air outside. According to the laws of thermodynamic, heat will always move from a place of higher energy to a lower energy space (hot to cold), robbing you of the comfort your home should otherwise have. Before that first heat wave in the summer or the below zero days of winter hit, take the time to double-check your home for potential leaks and drafts. To find air leaks, we start by walking through every room of your house and taking note of any obvious sources. Areas we check for air leaks include…
Window Sill Leaks
Over time, the sunlight erodes the synthetic sealing of weather strips around your window sills. The chill of winter followed by the warming of summer can cause the stripping around a sill to crack or break. We will make a visual inspection of the sill and look for damaged wood, weather stripping, or cracked glass around the edges. We will check to see if all weatherstripping and caulking have been applied properly and are in good condition. If we can rattle a window or see daylight around a window, you have air leakage.
Door Jamb Leaks
We will check for air leaks, and replace old door weatherstripping with new. Foam-type tape has an adhesive backing; it’s inexpensive and easy to install. If it comes loose, it’s best to reinforce it with staples. We check exterior trim for any gaps between the trim and your door frames, and the trim and your siding. We will advise you when you need to caulk gaps with an exterior latex caulk.
Seal Door Bottoms
If a draft comes in at the bottom, we will check the condition of the threshold gasket. We will advise you when to replace worn gaskets. If we can see daylight under the door, we will advise you to install a new threshold with a taller gasket. Or, we will advise you to install a weather-resistant door sweep designed for exterior doors. Door sweeps attach directly to the door and are easy to install.
It’s a good idea, especially after a storm, to examine your home from the outside. Walk around the full exterior of your home and look for damage to vents, exhausts, siding, and the roof. If there’s a dent, missing shingle, or crack, you may find a hole as well. On the outside of your house, inspect all areas where two different building materials meet, including exterior corner, outdoor water faucets, where the siding and chimneys meet and the ares where the foundation and the bottom of exterior brick or siding meet. Take pictures to show us of problem areas.
Testing for Drafts
There’s one other method we use to test for leaks in your home, a smoke test!
- Close all exterior windows and doors in the home, leaving internal doors open
- Shut off the central air and any ceiling fans.
- Light an incense stick and watch the smoke. If it moves sideways, it’s following an air current in the room.
- Follow the smoke trail and see if it leads to a gap or an exit.
- Use this method around windows, doors, and vents to find tiny gaps and leaks.
