"We had a great result using them.  I originally called because of an issue in a room with a bay window - it was very cold in the window, as though they didn't insulate properly underneath.  They offered to come in and do the energy audit.  Their recommendations were reasonable, and included a fix for the bay window insulation issue.  There was no "hard sell".  Their estimated savings for implementing the improvements were $1700 / year.  We had the option to finance and roll the costs into our PSEG LI bill, or pay up front (and get a small additional discount).
I've recommended them to others, who have had similar positive results.

"We have a building and it is so old that it never had insulation in the walls. The winters were very uncomfortable because of the cold that would come thru the walls. Sound from the apartment above carried like the person above was right next to you. I called Ecorite and made an appointment with Danielle to have an estimate. Uri was on time and took measurements then gave us a written estimate. Big wow for us since most of the time we are given a verbal one that keeps changing until a contract is written. We told Uri our issues and he made suggestions. He explained the products and how they use them. Closed and open cell materials and what walls they need to go on. Next was the actual installation. We had to make some changes and Danielle made sure the contract was updated and I approved the changes. She made sure everything ran smoothly. When the workers were on their way Danielle made sure I knew it. When the Kenneth and Lucas (the workers) arrived they were on time and greeted us then introduced themselves. They were friendly and pleasant and they made us feel comfortable with their knowledge of the product, and respectful of our home. They instructed us on how to reduce or eliminate any incontinence to the other tenants of the building. During the installation they worked non-stop, until they broke for lunch. After lunch break they were in a hurry to get back to work. There was no slowness here; if I had to use a word I would use quick€. After the job was done they cleaned up and took out the trash (which for us is a big thing). The entire job was a pleasant experience. I will be calling back for the next apartment. If not for Homeadvisor I would not have found such a good company. We are very happy."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"We just had a roof done by home genius exteriors. We started with Justine at our door setting up an appointment for someone to tell us about the process. The next day Dan came and explained how the company works. He even crawled around our attic to show us the damage. Within 2 days our roof was in the process of being installed. Zach the project manager stopped by 3 times during that day to see how the work was being done. What a professional company. Everyone that we spoke to or met was very professional and friendly,. I would highly recommend this company for installing a roof."

"This company was extremely reliable and worked very fast to get the job done. We used them to renovate an apartment for rent and they were honest with their prices and even suggested options to save us money. We would definitely utilize them in the future and recommend them. I wish I had taken before and after pictures to show what a great job they did. Also, we were really impressed that the contractor sent us pictures and contacted us every time they completed anything."

FAQs for insulation service projects in Roslyn Heights, 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.
