When to use this page

Many homes in this area — especially older homes and seasonal properties — benefit from insulation upgrades, air sealing, and moisture control. Poor insulation and air leaks make homes uncomfortable year-round and drive up heating and cooling costs.

Cold rooms or uneven temperatures
Drafts around windows, doors, or floors
High heating or cooling costs
Ice dams forming on the roof
Moisture or dampness in basement or crawl space
