Weatherizing – An Inexpensive Way to Save Energy and Money
Would you leave a window open in the middle of winter with your furnace or boiler cranking? That’s basically what you’re doing if you don’t weatherize your home.
That’s right: the average American home leaks an amount of air equal to a four-foot hole in an exterior wall through spaces around windows and doors, and through the walls in its attic and crawl spaces.
That’s why weatherization is one of the best bang-for-the-buck investments you can make in your home – especially when it’s done in combination with installing high-efficiency heating and cooling equipment.
Weatherization Checklist: Locations and measures to consider
Use this list as a reference of the many places to check for air leaks around your home (an energy audit would give you a more detailed analysis – contact us to learn more).
Exterior windows and doors
Check for and repair/replace loose panes and broken glass.
Caulk around windows and doors frames.
Weather strip and install door sweeps on exterior doors.
Seal windows with weather stripping or rope caulk.
Attic
Install foam weather stripping around attic door edges.
If you have a chimney, seal around it with a high temp sealant and metal flashing.
Caulk around plumbing vents that pass through that attic floor and ceiling.
Seal gaps between the attic and living spaces with expandable foam or insulation.
Basement
Seal gaps between the attic and living spaces with expandable foam or insulation.
Seal and insulate accessible ductwork.
Caulk around basement windows and external-facing doors.
Seal holes and gaps around foundation walls using caulk or foam sealant.
Living spaces
Install foam gaskets behind electrical plate covers on exterior walls.
Seal cracks and gaps where floors meet exterior walls.
If you have a wood-burning fireplace, close the damper when it’s not in use.
Outdoors
Use caulk and expandable foam to seal gaps around penetrations through the home’s exterior shell, including HVAC, plumbing, electrical and water lines.
Caulk around all door and window frames.
Make sure your dryer vent cover works; if not, replace it.
Seal gaps where building materials meet, such as between brick and siding.
