"We moved into our house in the winter and found out that the 70 year old insulation was quite deteriorated and moldy in the fall. We decided to have the old insulation removed so that we could cut down on heating bills and get rid of the smell. I contacted several companies and interacted with Joe from Good Life as the salesperson. He was kind enough to come to our house twice as the scope of the project changed. Both times, he drafted the proposal right at the end of the visit. His professionalism and the quoted price convinced us to go with Good Life Energy Savers. On day 1, the first crew came to remove the old insulation from the attic and used open cell spray foam to insulate the basement rim joists. On day 2, a second crew came to apply blown-in fiberglass insulation in the attic. Please note that the material they use is not irritant at all. Both crews worked really hard and cleaned up very well after they were done. I was especially impressed with the job 1st crew did to remove the old insulation from the slopes on a cathedral ceiling. My only minor complaint is regarding the patch in the ceiling at the end of the job. The guys used paper tape and there were bubbles all around. I guess they were very tired at the end of the day. Initially, I was planning to paint the room myself to cover the patch. But after removing the paper tape (due to bubbles) and using fiber mesh tape and joint compound, I figured I wouldn't be able to smooth the edges of the patch perfectly and hired a professional. Overall, it is a great company that provides quality job at a reasonable price. With the new insulation, the furnace runs much less frequently and I am pretty sure the job will pay for itself very in a few years."

"Our house was suffering for many years from poor insulation, leaks through doors, windows and vents, and drafts everywhere. I was tired of seeing my wife wear a scarf in our family room while she was watching TV. We bought a propane gas log for our fireplace, but that did not eliminate the drafts, and when we turned it off, the temperature quickly dropped. We decided to do something about it. I had received a mailing from a big company who claimed they specialized in making homes more comfortable. A salesman came to my house, but I was surprised to see he had no interest in checking my doors, windows, or AC vents for leaks, even after I mentioned that I knew my doors and some windows where allowing drafts. Instead, I quickly realized that all his company did was install insulation. To his credit, he did go into my main house attic, the attic over my family room, and the basement. He was in my house for four hours, but half of that was purely "selling" In the end, he quoted me a price of $10,300 for the entire job. I did not have anywhere near that amount of money to spend, and so I scoured the internet for local companies who did similar work. I found several and selected Eco Energy Guard, mostly because of their website and my gut feeling that I would get an honest assessment and a fair shake. Bill Brown, the owner, came a couple of days later to do an energy assessment, was in my house for about two hours, and gave me a quote ONE-QUARTER of what the other guys quote was. The huge discrepancy in price was primarily due to Bills approach to making the house more comfortable. For example, whereas the first guy wanted to remove all of our current insulation and REPLACE it with his own, Bill wanted to ADD additional insulation to what he saw as perfectly adequate existing insulation. The first guy wanted to spray foam along the entire basement rim, whereas Bill wanted to spray foam only in the one area where there actually was a leak. Bill also was interested in sealing leaks that caused heat to escape, none of which the first guy was interested in addressing. For example, one of the big leaks was through a door that connected the family room with the garage. He found cold air coming in through an air conditioning duct. He saw that hot air was escaping through the vents of a whole house fan. And he found cold air entering our bathroom because the window had serious leaks and because the clothes dryer vent on the outside of the house was faulty and stuck in an open position. Bills cost included all of these fixes and was still 75% less costly than the first guy. Besides the great price, I also had great confidence in his ability to do a great job, especially because he would actually be on the job. A week later, Bill came and did all of the work he had promised. It has been a week since the work was done, and I can say with certainty that there are no longer drafts where there had been before, especially in the family room which had resembled a wind tunnel. I have noticed that when the furnace kicks on and heats the house, that heat is retained. If I put the propane log on in my fireplace, I only need to keep it on for 30 minutes, then I can shut it off because the heat is retained in that room. In summary, I will say that Bill offered a solution that included only what I needed, and his price was fantastic. In a few months, I plan on having him install a solar fan in my attic so that my AC wonâ  t have to work as hard keeping the house cool. Thank you, Bill."

"They were very professional, took care of helping me get the home energy audit and the rebates for attic and wall insulation. Also improved attic ventilation installing soffit vents and baffles. We got three estimates and they were a very good price, but the service is what sold us."

"Perfect wall LLC service was amazing! They went over the job with me and explained everything and taught me a thing or 2 about insulation. After the job I went to look at the results and it was exactly how he explained it! They use measuring templates you can see the actual depth of the insulation in all parts of the attic which was awesome. The vent out the exterior wall was so perfect I couldn?t even find it unless I really looked. Everything came out perfect they took the time to clean up very well also which my wife was very happy about! 10/10 would use again."

FAQs for spray foam insulation projects in Hartford, CT

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
