Home Insulation

Simple repairs mean significant savings

Two quartersIf you can stack two quarters between your doors and doorframes, it's like having a hole to the outside in your living room wall. Similar gaps throughout your home all can add up to the equivalent of leaving a window open year-round. A well-insulated home doesn't just keep you warmer in the winter. It will help keep you cooler in the summer, too.

You may qualify for rebates of 20 percent of your project cost (up to $1,400) if you heat with electricity and employ a contractor to upgrade your insulation.

The benefits of insulation

  • Reduced heat loss
  • A cost-effective way to lower your energy bills
  • Ensures home safety—in addition to installing insulation, contractors check your energy systems to make sure they’re working properly
  • Improved home durability, by keeping outside elements out and reducing moisture
