"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."

"Great. Jeff quoted our specs, & did an in-house visit. He reviewed the entire project. He made sure Our expecting were realistic, before going on. Everything was clear, & got a competitive price.. We have noisy upstairs neighbors in Condo yelling & loud TV, RADIO,MUSIC & the project helped reduce it by 30-65%. It is hard to be specific without decipel meaning equipment. The cellulose bags say 60%, however Jeff pointed out expect 35%- that honesty, eventhough we got better. If you do a similar job, make sure you understand IMPACT noise, which is not what this project can do. So we are not disappointed, & got what we asked for. The noise was reduced, but not eliminated. This will keep us in a holding spot, in that we might not have to move for now, as moving is very expensive. This kind of improved our quality of life. Our contractor Juan & Dillon were Professional, respectful of our home & exceeded all posted reviews. "Was money paid or were services performed?*-bad question!"

"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."

"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. "

"We live in Gainesville, FL and are on Gainesville Regional Utilities. We were working on getting solar panels around the time GRU was lowering the limited coverage. Our paperwork was done and submitted to EnLight Energy before the April 2024 deadline. Fast forward. We start getting our electric bills, they were lower, so we didn't think to much about it. After a few months with the same price, much more than we estimated, we questioned it. We got ahold of GRU we discovered EnLight Energey FAILED to submit by the deadline even though they PROMISED us it was submitted in time. We contacted EnLight about this and of course they blame GRU and said no, they're lying, we submitted it on time. We're now halfway through December 2025, over a year later and they still haven't done ANYTHING. They are trying to avoid fixing their mistake that is going to cost us quite a bit over the years because THEY missed the deadline. We've given them a lot of time and a lot of chances, would NOT recommend."

FAQs for batt, rolled or reflective insulation install or upgrade projects in New Fairfield, CT

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
