How to Caulk and Seal Around Windows and Doors

By: Allen Lyle

Gaps around windows let heated and cooled air escape and increase your energy bills.

  • Fill small cracks and gaps with caulking.
  • Fill larger cracks with foam backer rod of the appropriate size by pushing it into the gap with a putty knife, then apply caulking on top of it.
  • Still larger gaps and holes can be filled using aerosol cans of expandable foam. After the foam has cured, trim it flush, and stain or paint it to match the house.
