Air sealing your home is a way to reduce your heating and cooling costs, preserve a building, and create a healthier environment. Many people know that adding a weather seal or weather stripping around doors and windows is a common way to reduce air leakage. However, you can take some other measures to reduce the amount of air leaking out of your house.
1. Test Your Home for Air tightness
One of the best things you can do is have a professional visit and test your home for air tightness. They will identify any air leaks and what you need to address to seal your home.
2. Seal Around Pipes and Wires
It is always a good idea to caulk around pipes and wires that go through walls, floors, or ceilings. This includes caulking around plumbing, air ducts, and electrical wires.
3. Seal Around Your Outlets and Switch Plates
You can find foam gaskets designed to fit under your outlet covers and switch plates. These will reduce the amount of air that leaks out through these surfaces.
4. Inspect Your Insulation
Periodically check your insulation for holes. If you find any, be sure to fill them with spray foam insulation. You should also make sure that there are no cracks in the outside wall of your home. This prevents water from entering and getting the insulation wet. Once it is wet, it is likely to get moldy and deteriorate quicker.
5. Cover or Replace Single-Pane Windows
On historic homes, you should consider covering single-pane windows with storm windows. If you can, you should consider replacing them with double-pane windows. This will reduce the amount of air that escapes through your windows.
There are many ways you can make your home airtight. Some of the easiest ways to do this involve simple things you can purchase at your local hardware store or online. They are often something that DIYers can do on the weekends.
