"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."

"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."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Newtown, 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.
