Sealing cracks, gaps, leaks and adding insulation can save up to 20% on home heating and cooling costs.
• Add weather stripping around windows and doors to reduce drafts.
• Use caulking and sealants to seal around ducts, plumbing and any other openings in walls, floors and ceilings to reduce air leakage.
• Seal larger gaps that cannot be covered with caulk with expanding foam.
• Have your heating and cooling ducts professionally sealed to save up to $120 in coastal areas and up to $190 inland per year.
This you might have a leaky seal? Hold a lit incense stick next to the suspected area (plumbing or ceiling fixtures, attic hatches, windows, etc.). If the smoke stream travels horizontally, you found the leak. Weather stripping and caulk can help seal you in and the hot air out!
