Frequently Asked Questions

Weatherizing your home involves making physical home improvements-such as insulation and air sealing-to reduce energy costs, improve comfort, and resolve issues such as ice dams, moisture, mold, cold spots and drafts. Improvements often focus on basement and attic areas.

Your first step is to identify and hire a specialized contractor who will perform an energy audit to assess your home’s current energy efficiency and identify the best energy-saving opportunities for your home and budget.  You may do this on your own or go through the NHSaves rebate process.  Energy audits through NHSaves cost $100.  When you hire a contractor on your own, the cost is determined by the contractor. and will vary. 

Every home is different. Costs typically range from under $5,000 to over $12,000, with average energy savings of 20 to 25%. Alternatively, you might try some "do-it-yourself" energy efficiency improvements or invest in a deep energy retrofit to reduce energy use by 50% or more.

Rebates up to $4,000 (eligibility based on fuel use per square foot) are available from NHSaves on a first-come-first-serve basis. If interested, apply immediately. Weatherize Hanover and our associated contractors are available to all homeowners whether they participate in the rebate program or not.
