"The product was well provided and the product was easy to install. I didn’t have to outpunch the old insulation and I could just leave it where it was. The guys were good at what they did. Stinky but beyond that we just let air out for a while but it disappeared in a couple of days. They finished the work in one day. The quality was good and they went beyond what they promised."

"After an extensive process of having different contractors evaluate my home & submit their estimates for the installation of a Bosch tankless boiler/water heater combination unit as well as new baseboard heating, I selected AStar Heating & Cooling. Their staff impressed me from start to finish. Initially, I met Aaron who provided a thorough explanation of how the work would be done, offered other options that I did not know of or considered at the time, and provided a fair estimate that was similar to most of the other contractors. Next, when the time came for the projects to be completed, the technicians, Robert & Trevor, were on point. They always arrived in a timely manner & started working right away. They worked efficiently & quickly to get the projects done in the time frame promised. However, they did not rush, they took pride in their work & made every effort to make sure the work was completed neatly & done properly, as they thoroughly tested out the systems to make sure their were no issues/problems in their setup & performance. They also thoroughly answered my questions about the installation of the new systems as they went about their work. At the end of each workday, they made sure to clean up the job site & were very mindful in not dirtying my new floors by wearing plastic booties whenever they had to walk over them. The Bosch tankless water heater/boiler combination unit has been working without a hitch. I barely notice the difference in the time lag of receiving hot water in comparison to the old 40 gallon tank water heater I previously used. Overall, I highly recommend AStar Heating & Cooling. High quality work done high quality professionals. All of them put my mind at ease on what was a very necessary home improvement project."

"R-Factor Insulation Company does very good work. They insulated my crawl space and did a wonderful job. The owner Mr. Knapp was very professional and came out and gave a free estimate on the work. The job estimate was right on the price with no cost over runs at the completion of the
job. I had other estimates that were much higher on the same work to be done."

"They removed old moldy insulation, sprayed fungicide on the mold and encapsulated a crawl space. Also insulated with foam insulation around the entire basement rim joist, including the crawl space. They were on time and finished before they expected to. During the inspection, when I pointed out bubbles in the foam, they redid that section without question. Zy called after they finished to make sure I was satisfied."

FAQs for insulation service projects in Windham, 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.
