"I got several estimates from several providers. The pricing seemed just ok with those other providers but something seemed off. Good Life came in and made sure that I was getting the correct amount of insulation (where the other service providers had under estimated) and helped me to get into a loan through the utility company for the cost of the insulation. Good life is a qualifying contractor for this and it saved me a lot of out of pocket expense. They came in and did what they had to do. They were professional and made sure the work was done well."

"Ecofoam insulated my attic with closed-cell spray foam and the results came out great. The space feels completely sealed and much more comfortable already. Sevi and the team were very professional, easy to work with, and kept me updated throughout the whole process. I would highly recommend EcoFoam for anyone looking for quality insulation work."

"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."

"It has been 3 years since I installed a full perimeter water proofing system from CT Basement Systems. I waited 3 years to see how the system held up over time before offering this review. Bottom line, after years of having constant water in my basement, the system has done what it promised to do. My basement has remained dry for the most part. Immediately after having the system installed, we identified a few spots where there were penetrations through my basement wall where water was coming in and overshooting the perimeter system. All but one of these spots have been fixed. There remains one last trouble spot which is where the flue pipe for my furnace comes through the wall that water still seeps through but only under the most serious (hurricane type flooding) water conditions. It is not something that we would have expected the system to prevent as water follows the flue pipe past the system and onto the floor. We will be addressing it to finally have a dry basement once and for all. I understood immediately what the system would and would not fix. Of all the contractors I spoke with CT Basement Systems was the only one who was up front and honest about how their system would work, what it would fix and what it would not fix. This was one of the reasons I finally went with them, low pressure, up front honest sales. To all those other basement system companies sales people who tried to convince me my house was going to collapse if I put in any other system but theirs, take note. My house is still standing. The installation was messy and noisy (as promised) but it was all done in a day, and they left it neat and clean (expect for all the dust) and professional looking. After 3 years, not a single drop of water has made it past the perimeter drain channel. I did need to replace a float switch on one of the sump pumps (I have the triple safe pump) but that is the reason i went with the triple safe pump system. What I realized is that all these basement systems are the same idea. Create some type of channel to create a path for the water to drain to a collection point. It then gets pumped out. All of these systems from all the different companies are the same idea and all try to convince you that theirs is unique and better. I personally feel they are all the same as they all work. What is critical is the pump system. It was basement system's triple safe pump concept more than anything that convinced me to go with them. With all the others, a single pump failure would have caused a flood. So read their informative book carefully and listen to their sales people and ask questions. So long as you understand what the system will and will not do I don't think you will be disappointed."

FAQs for insulation service projects in Lakeside, 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.
