"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.

"Zaza seal did a blown in insulation project for one of my bathrooms, yesterday. They were punctual, highly professional, and left the area where they did the work looking like it had never been touched, which was great. They cleaned up well, afterwards. The supervisor on the job, Anderson, could not have been nicer or more responsive to my questions."

"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."

"Danny and the crew did a great job on my attic insulation. I look forward to hiring them for my next project which is having blown in insulation for the walls of my home. They where clean and thorough. I will also recommend them to my Co-workers."

Insulation questions, answered by experts

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

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.

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.
