Weatherization Checklist: Locations and Measures to Consider

Checklist

Would you leave a door wide open in the middle of winter with your gas heater or pellet boiler working overtime to keep your family warm? That’s what many homeowners are doing if they don’t properly weatherize their home.

The average American home leaks an amount of air equal to a four-foot hole in an exterior wall – mostly through spaces around windows and doors and through the walls in its attic and crawl spaces.

To minimize those leaks (something you should definitely do), you will need to weatherize; while it may take some time, money, and effort, it’s actually one of the best energy efficiency investments you can make for your Finger Lakes-area home (right up there with installing high efficiency heating equipment).

Weatherizing: What to do and where to do it

Use this list as a reference of the many places to check for air leaks – if you want a more accurate assessment of your home’s problem areas, consider investing in an energy audit from a reputable contractor.

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
