"Very easy to work with. The owner himself came out to give me an estimate. Mark completed the actual insulation. He was quick and he did a great job cleaning up the area after doing the spray insulation. Highly recommend!"

"Stephen and his team did a fabulous job of insulating a space behind a bedroom wall and adjacent bathroom wall that was completely uninsulated. We suffered through two cold winters that heaters couldn't solve in these rooms. Stephen evaluated the project efficiently and then oversaw the work. It was performed beautifully by the team and they cleaned up before leaving. Everything was immaculate. Most impressed with this company and this project manager."

"The insulation was fast. They did a good job cleaning up. They quickly resolved a problem that occurred. The sales man Seth was super nice and took time to answer my questions. Ami from the office was very good at communicating with me throughout the process."

"We are finishing our basement. We put up framing, insulation and paneling only to discover we had a condensation problem. We contacted a locally well known water damage and restoration company. After waiting two weeks, they called to tell us they were not interested in working with us. During these few weeks, we tore down the paneling and insulation.  We contacted Superior Insulation after noticing their great reviews here on Angie's List. We talked to Rick who gave us an idea of what the solution was and set up an appointment to view the problem area. Once he saw the problem area, he decided on a slightly different solution. Contract signed 3/18/15. Work completed  by Rick and Jim 3/30/15. They were very professional, thorough and nice to deal with. We are very happy with what they did.

"These guys were great. They insulated my attic efficiently, and they discovered a wall between my garage and bedroom literally had no insulation. They were able to fix that quickly for a very reasonable cost. I like that they show you before and after videos!"

Insulation questions, answered by experts

When hiring a Hanover insulation contractor, prioritize those with experience in local building codes and climate conditions. Confirm they carry proper insurance and hold certifications for the materials they use. Ask about their familiarity with older or historic homes, and request local references. Be wary of contractors demanding full payment upfront or using aggressive sales tactics. For winter projects, schedule early to secure your preferred timeline.

Helpful?

In Hanover’s climate, spray foam is excellent for sealing air leaks and boosting energy efficiency. Blown-in cellulose is ideal for attics and resists moisture, while fiberglass batts work well for standard wall cavities. Installing vapor barriers is important to manage humidity, and rigid foam boards are particularly effective in older basements. Radiant barriers can also help reduce cooling loads during Hanover’s warmer months.

Helpful?

Upgrading insulation in Hanover directly improves your home’s comfort by keeping indoor temperatures consistent during both hot summers and cold winters. Effective insulation reduces drafts, helps control indoor humidity, and minimizes outside noise—especially useful if you live near busy roads. You’ll likely notice lower energy bills and less strain on your HVAC system, making your home quieter, healthier, and easier to maintain year-round.

Helpful?

Insulation in Hanover provides immediate benefits like improved comfort, reduced allergens, and lower utility bills. Over time, you’ll enjoy increased property value, protection from rising energy costs, and a longer lifespan for your heating and cooling equipment. Quality insulation also helps prevent moisture issues and ice dams, supporting a healthier indoor environment and reducing your household’s environmental impact.

Helpful?

In Hanover, attic insulation projects typically take one to four days, while whole-house retrofits may require three to seven days. Basement or crawl space insulation is usually completed within one to four days. Factors like weather, home age, and permit approval can influence timelines, especially for historic homes or during winter. Planning ahead helps avoid delays and ensures a smooth project from start to finish.
