Posted: November 20, 2017

You wouldn’t leave your window open in the middle of winter, would you? You could be doing just that if you don’t take steps to weatherize your Seacoast-area home.

The average amount of air that leaks through spaces in the exterior shell of an American home is about equal to what would leave the house through a four-square foot hole in the wall. Talk about throwing money out the window!

That’s why weatherizing your home is such a no-brainer investment – especially when it’s done in conjunction with installing high-efficiency heating equipment.

What to weatherize in your southern Maine or New Hampshire home

Not sure where to begin your weatherization journey? Here’s a guide to some of the potential trouble spots in and around your home.

Around windows and doors

  • Repair/replace loose panes and broken glass
  • Seal around window and door frames with caulk
  • Install weather stripping and door sweeps on exterior doors

In the attic

  • Install weather stripping around attic door edges.
  • Seal around the chimney with metal flashing and temperature-resistant sealer.
  • Caulk around plumbing intrusions that pass through the attic floor and ceiling.
  • Insulate walls and voids between the attic and living spaces.

In the basement

  • Insulate walls and voids between the attic and living spaces.
  • Seal and insulate accessible ductwork.
  • Seal around window and door frames with caulk.
  • Seal gaps around foundation walls using foam sealant.

In your living spaces

  • Install foam gaskets behind switch plates on exterior walls.
  • Seal gaps where floors meet exterior walls.
  • If you have a fireplace, close the damper or flue when not in use.

Exterior measures

  • Use caulk and expandable foam to seal the home’s exterior shell, including extrusions for HVAC, plumbing, electrical and water lines.
  • Seal around door and window frames.
  • Check your dryer vent cover; if it doesn’t work, replace it.
  • Seal gaps where building materials meet, such as between brick and siding.
