"Lomont and his team were great to work with, simply professional, knowledgeable and so accommodating. I hired him based upon an energy audit we had done by another company. He basically "cleaned up their mess" since they did not do a thorough report in order for us to get our energy rebate etc. He went above and beyond the scope of what we hired him to do, always with a friendly greeting and smile. He reached out to the appropriate agency to push to get the credits we were due and did work that should have been done by the energy audit company. I highly recommend Lomont."

"The crew worked quickly and efficiently to replace and upgrade the fiberglass batts in our basement and crawl space. I’m pleased with the outcome. (I put in even more wire supports afterwards — to secure the insulation between the joists — but that’s just my OCD.) It was a relatively small job for this company and I thought the cost was fair."

FAQs for spray foam insulation projects in Derby, CT

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.

It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.

Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
