Home Insulation

Simple repairs could mean significant savings

If 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 helps keep you cooler in the summer too.

You may qualify for a rebate of 20% 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

The benefits of a well-insulated home are numerous! Proper insulation:

  • Reduces heat loss.
  • Is 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.
  • Improves home durability by keeping outside elements out and reducing moisture.
