"Wonderful outcome on me and my neighbor's roof. All in all I am impressed with the quality of material and the process of installation. Our experience with the very kind salesman was interesting in the best way possible. We've learned so much from him. While watching the crew work vigorously we learned a lot from them too. Our project manager Taylor gave us a final walkthrough to make sure we ended on a great note, which we did. Home Genius treated us well."

"the insulation they recommended saved me about 5000kw a year. the amount of money i am saving is far more the insulation payment on my Eversource bill. No money cost to me out of pocket and my electric bill dropped quite a bit. best move i ever did."

"I had a variety of small handyman projects - replacing doorknobs, patching holes, fixing molding, etc. the guys were very polite, professional, and knowledgeable. They took off their shoes to enter the hose, and did a great job, and kept me informed the whole time. I would definitely recommend them and hire them again!"

"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 Old Greenwich, 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.
