Each season in New England brings with it a unique set of challenges when it comes to the comfort and energy efficiency of your home. While it’s important to stay on top of seasonal changes, like sealing drafty windows with heat-shrink plastic, there are ways to save money year round by weatherproofing – regardless of the current season. We’ve rounded up 10 of the best tips to start you on your way.

  1. Put an insulating blanket around your water heater. Always check the manufacturer’s manual first, as some newer models should not be wrapped.
  2. If you have a fireplace, close the damper when it’s not in use. Try not to use the fireplace and central heating system at the same time.
  3. Close and lock windows when heating or cooling your home. Install shades, awnings, or sun screens on south- and west-facing windows to block summer light. In winter, open shades on sunny days to help warm rooms.
  4. If they aren’t already, insulate ceilings to R-49 standards. Proper insulation is just as important for keeping your house cool in the summer as it is for keeping it warm in the winter. Click here for insulation R-values and what they mean.
  5. Caulk windows, doors, and anywhere air leaks in or out. Don’t caulk around your water heater and furnace exhaust pipes.
  6. Weather-strip around windows and doors. Wrap heating and cooling ducts with duct wrap or mastic sealant.
  7. Replace old windows with new high-performance windows.
  8. Look to common areas, like ductwork; fireplace flues; kitchen and dryer vents; plumbing fixtures; pipes and wires; gaps between floors, walls, and ceilings; crawl spaces; doors and windows; and attic openings for potential air leaks.
  9. Keep your roof in good repair, and replace any cracked or curled shingles before the rain or snow arrives.
  10. Keep gutters and downspouts free of debris to prevent the accumulation of water around the foundation of your home.
