Home Weatherization

Sealing doors and windows, winter-proofing your pipes to prevent freezing and making sure you have proper insulation can save you headaches and avoid unnecessary expenses. 

Weatherizing your home is a simple and sensible way to reduce your bills.

Insulation Works

Acting as a shield for your home, insulation blocks the loss of heat in the winter and keeps your home cooler in the summer. Did you know that insulation comes with a rating? The higher the rating, or ‘R-Value’ the insulation has, the more effective it will be. We recommend choosing insulation that has the maximum rating for your climate zone.

ENERGY STAR® estimates you can save up to 20% on heating and cooling costs just by insulating and sealing your home against air leaks alone.

Types of Insulation

  • Attic: The easiest location to add insulation is in the attic. This is recommended if your home was built prior to 1980, if you experience excessively high energy bills, or you’re uncomfortably cold or hot during winter and summer.
  • Floor: Believe it or not, heat loss can occur through the floor of your home, where crawl spaces or basements can allow a substantial amount of warm cozy air to escape at a rapid pace.
  • Windows: ENERGY STAR®-qualified windows, including those with low-e coating, double panes, and vinyl or fiberglass frames, lend to ways that you can insulate your home, saving energy and money in the long run. Look for windows with the lowest U-value, as these are the most efficient.

Increase Your Efficiency
