"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."

"I found Score Construction on Home Advisor's website. I was looking for a contractor and needless to say I read reviews for many of the construction firms. Every review I read was terrific for Score Construction and because of that I called, met Janusz Z who is the Owner and was very impressed with his knowledge and professionalism. I started with 2 bathrooms that were necessary to do because of water damage. I was thrilled with the work done, the care of how it was done by the workers that were both professional and respectful. A year later a major renovation for my apartment was considered and I called Score Construction. Not only did the renovation to my apartment turn out fabulous and I'm happy every day that I wake up and see how beautiful it is, but they also did major work to the outside of our building - replacing the cornice, roof repair, pointing of bricks, structurally reinforcing all 16 windows which was no easy task for a 100 year old building, but they got it done. ALL this work again was done professionally and with the utmost of care and the knowledge of how to get the job done is their forte'. Every experience that I have had with Score Construction workers and owner, Janusz Z has been top notch. I recommend Score Construction HIGHLY. You will be extremely happy that you did so."

"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 questions, answered by experts

Sometimes you may be able to leave the bags with your regular trash. However, that’s not always the case. Call your local waste management prior to starting the removal and ask about the proper ways to recycle or dispose of removed insulation. In many cases, your town or municipality has a designated dumpster for building waste.

Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

You can buy pipe insulation materials in your local hardware store or in major home improvement stores. You can also shop for insulation online, where you may be able to more easily buy in bulk. When shopping, make sure you know your pipe's dimensions so you can buy the correct size of pipe insulation materials for your pipes.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).
