"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."

"They showed up exactly when they said they would. They were efficient, neat and made sure to send me pictures in the various stages of execution. And they cleaned up better than when they found the area. I would highly recommend them. I wish he did more than insulation because he would be my go-to guy for all house related needs."

Insulation FAQs, answered by experts

Yes, crawl space insulation is worth it if installed correctly. Installing insulation in your crawl space will improve the air quality, help stabilize your home's temperature, lower your energy bills, and prevent pests from entering your home. Though you’ll pay more to install insulation initially, the savings you get from installing insulation can help offset those initial costs over time.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

How to dispose of insulation depends on a few factors, including the condition of the material. While you can simply bag up and throw away many kinds of insulation, some municipalities offer recycling, so it's worth checking with yours. If there are contaminants such as asbestos in your insulation, abatement and specialized disposal are often necessary.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

Hanging a thick blanket over your windows will help to keep the heat inside, but only a little. Covering the glass will also prevent the sunlight from getting in, which might actually decrease the efficiency of your window overall. If you get to the point where you’re hanging blankets over your window to keep warm, call in an expert to seal around your windows to prevent warm air from escaping. They may also recommend replacing old windows that aren’t as insulative as newer window technology. Sealing a window isn’t terribly expensive and can make a big difference.
