"I recently hired Sebastian and his company to install new fiberglass insulation and Densepack in my attic. I found them to be extremely professional. They did the work as quoted, cleaned up after they were done and took all the trash away. I would highly recommend them."

"We had a freezing bedroom in our house as well as a freezing entry way. Turns out it was above the garage with zero insulation. Mike came out and from the start understood what was creating the issue. Not only he is highly knowledgeable about home construction in general, he was an absolute pleasure to work with and hilarious! The team at Acorn was able to schedule us in 2 days before Christmas. If you were in the North East around Christmas 2022, you experienced that deep freeze that came through. If you want to know if your home was insulated right, nothing like freezing temps to show you. Acorn did a thorough and professional job and installed blown and fiberglass insulation. Our room was toasty with no indication of how cold it was outside. I cannot thank them enough!"

"Howard Falkow was incredibly helpful and responsive from the beginning.  He walked us through the analysis of the energy leaks in the house and outlined several options to help us save on our energy bill.  Rather than immediately pitch us on the most expensive option, he gave us an objective cost/benefit analysis as to which package would result in the best energy savings per cost.  
Howard was very responsive over email as well as on the phone and he and his staff were always friendly, professional, and very accomadating when it came to scheduling. 
Howard and NY Metro Insulation provide an excellent service for anyone who is looking to make their home more energy efficient.  They are honest, professional, and perform high quality work (we noticed results immediately after the work was performed) and I would recommend them very highly to anyone in the area.

"We had been living in our house for 5 years and although the kitchen was a new addition, every winter my wife & I had noticed how noticeably the temperature differentiated especially after the winter of 2014/15.  And because it was a dirt floor with some wood and old construction debris strewn about.  I was not so keen on staying down there.  In doing my own investigation there was some piping and insulation under floor.
So when investigating estimates we called a number of "green" companies.  Out of the three companies that came, only Frank Petrullo with Eco Green Solutions, noticed the mold and a water leak coming from fridge line.  He took the time to show me where the water was coming, how mold had proliferated on the wood floor joists and beams.  The dirt floor was somewhat moist and light was visible from outside along foundation rim contributing to the mold and moisture in crawl space.  He explained each of our options and detailed the steps in sections of each estimate.
We opted to have a plumber fix the water leak, then franks crew came in, cleaned up the mold, then layed down the crawl space membrane, finally insulating floor & rim joist.  All in under two days.  The crew showed up on time, left the open sections of the house clean, and we immediately noticed a difference in kitchen and rest of house.  Walking around bare foot in kitchen is more comfortable, the kitchen is less noisy, and house humidity is maintained.

"Joe did a great job on this, our dining room was a add on to connect the original home and the garage and had no insulation and boy in the winter it was unusable as well as the kitchen basically (the best part of the house). Joe came and drilled small holes in the attic floor that they sealed up later to allow for blowing in the insulation. And they cleaned up well. we have a 20 month old but there was nothing left over for the baby to put in her mouth. Joe is great! Our dining room is toasty and the kids can play in there year-round Plus they are were less than half of the expensive "efficiency" guys PSEG sent over. Those providers wanted to charge $10,000+ for basically the same job."

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

"They arrived on time. They offered assistance with moving the furniture out of their work area. The workers made sure to cover the floors and all the furniture before they began their work. The work was completed in two days as predicted. They forgot to include one of the entryways ceilings In the contract. I mentioned this to the worker and after a phone call to Ari they proceeded to do the work. Although I would have liked to see Ari at some point during the insulation process, I believe the work was done well. We will wait for this coming winter to give our final verdict.

"Mike came and did a thorough inspection of my crawlspace which was once home to a family of raccoons. CleanSpace came and cleaned and disposed of all of the soiled insulation and sanitized the space before installing new and better insulation . The work was done quickly and as described, I would recommend them for anyone in a similar situation!"

"I LOVE my new deck! The composite material is so much better than the wood I used to have. It washes clean so easily and maintains a fresh look. My salesman from Paragon was very professional, courteous, and knowledgeable. He was very friendly and answered all of the questions I had and did not rush me. He explained everything in detail. I told them I had a very quickly approaching deadline and they purchased all the materials and had my deck done within two weeks of meeting them for the first time. I was so happy that they were able to meet my needs even in their busiest season. Thank you Paragon!! :)"

Insulation questions, answered by experts

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

A DIY blown-in insulation project in a typical attic should take you no more than a week to complete. Experienced homeowners can blow an entire attic in one or two days.

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”
