Frequently Asked Questions About Insulation in Gilmanton

Get answers to common questions about insulation services in Gilmanton, New Hampshire.

1What are the most important insulation upgrades for my older Gilmanton home to handle our cold winters?

For Gilmanton's cold climate (Zone 6), the most impactful upgrades are typically air sealing the attic and adding dense-pack cellulose or spray foam insulation in the walls and attic floor. Older homes here often have little to no wall insulation and significant drafts. Prioritizing the attic is key, as heat loss there is greatest, and it also helps prevent ice dams, a common issue in our region due to snow accumulation and temperature swings.

2How does the timing of insulation work in New Hampshire affect my project and its cost?

The best time for exterior work (like adding rigid foam to foundations) is late spring through early fall to avoid frozen ground and precipitation. However, attic and interior work can be done year-round. Scheduling during the contractor's slower periods (typically late winter or early spring) can sometimes lead to better pricing and availability. Avoid the peak fall rush when everyone is preparing for winter.

3Are there any local Gilmanton or New Hampshire regulations or rebates for insulation projects?

While Gilmanton follows the State of New Hampshire Building Code, there are no unique local ordinances for residential insulation. Importantly, you should check with the NH Public Utilities Commission for current rebates offered through the NHSaves program, which provides significant financial incentives for energy efficiency upgrades like insulation. Your local contractor should be well-versed in these state-wide programs.

4What should I look for when choosing an insulation contractor in the Lakes Region area?

Choose a contractor experienced with New Hampshire's climate and the specific challenges of older homes common in Gilmanton. They should be licensed and insured in NH and preferably offer a free, detailed energy assessment. Look for strong local references and ask if they are a certified installer for the NHSaves program, as this ensures they understand proper protocols to maximize your home's performance and your potential rebates.

5Is adding insulation to my basement or crawlspace really necessary, and what type is best here?

Yes, insulating your foundation is critical in our climate to reduce cold floors, prevent pipes from freezing, and lower heating costs. For unventilated crawlspaces and basements, installing rigid foam insulation boards or closed-cell spray foam on the foundation walls is the recommended method. This approach, rather than insulating the floor above, helps keep the space above the frost line warmer and protects against moisture from the soil, a common consideration in New Hampshire.
