"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."

"My experience with everyone was excellent. It started with an energy assessment followed up with spray foam insulation throughout my home. Good customer service and follow-up. All was explained thoroughly throughout the process and they welcomed my questions. I highly recommend this service."

"Anthony and his team did an incredible job insulating our full gut remodel in Fairfield. He took the time to put together a foam package that made the most of our budget. The crew was polite, neat and efficient. They took great care to cover finished surfaces before spraying and did a thorough clean up so we could jump right into sheet-rocking. Highly recommended for quality of work, constant communication and value!"

"I contacted Fausto from Tigasi Insulation to discuss a project in my basement. He arrived on time, and from the beginning, I could tell that he was a professional who takes pride in his work. At the end of the job, Fausto personally asked me to inspect the work that had been completed. I was very impressed with the quality of his work and the excellent job he did. I highly recommend Fausto and Tigasi Insulation to anyone looking for professional and reliable service. Thank you, Fausto, for the great work!"

"Their crews for the demo and both the waterproofing and renovation were great: on time, cleaned up, beautiful work. The estimator/salesman Tarn did a fabulous job in working within our budget without any high-pressure sales tactics, and was so patient with all my questions. I had first considered using a different contractor to do the renovation, but in the end, even if it might have been a bit more expensive, they made the waterproofing to renovation process seamless and hassle-free."

FAQs for insulation service projects in Katonah, NY

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.
