Weatherizing your home by updating old windows and insulation can make your home more efficient and comfortable.

If your house was built before 1988, and you have electric heat, there's a good chance these simple upgrades could save you money for years to come.  

We Offer:

We Cover Up To:

    • 50% of the cost to insulate ceilings, floors and walls.
    • 25% of the cost to replace inefficient windows.
    • 100% of the cost (up to $450) to test and seal your home duct system. 

In addition, Our Grant Program may help eligible income-qualified customers cover most of the cost of new windows and insulation.

How Much Does Weatherizing Cost?
Costs vary for each home. The approximate cost to weatherize an average 1,300 square foot home is about $2,800 after applying our window and insulation rebates. With our available 7-year, 0% interest loan, the average monthly payment is $35 per month. 

Manufacturer Rebates
Manufacturer rebates can be applied to lower costs even further. Ask your contractor about other rebates that might be available for your project.
