"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

"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."

"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.

"Excellent! I am very pleased with the work they have done. The team were prompt, thorough, and displayed professionalism. They went above and beyond the call of duty. They finished the job clean and fair. I put a dehumidifier when completed, and the result up to now? - dry basement, musty odor gone! I am one happy and satisfied customer, i would hire them again, and would recommend them to anyone."

"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!"

"Vincent arrived early for the quote which impressed me. We reviewed the project and he advised a price on the spot (which surprised me). I asked a lot of questions about timing and what was/was not included. I liked that there would be a project manager to oversee the project so signed the contract even though it was a lot more than I had expected. Paul, the Director of Projects, was assigned to my project which I thought would be a good thing. When Paul came out for the pre-production meeting, his estimate on the length of the project was different than Vincent's estimate. There were also questions about what was/was not included in the scope of work even though I thought we had clarified everything. Paragon did agree to cover the items agreed to by Vincent even though it was not in the contract. I appreciated that. Paul came out for the first morning of the project. When he left, I asked how often he would come by. He said he tries to come by every day during a project. Plus, there were multiple projects going on in my town so it sounded like he would be in the area. Needless to say, he came for the rough inspections and then did not come back for over a week. When he did come back, he realized that the team had not tented/tarped my room and my bedroom was covered in dust and dirt. He apologized and sent someone to clean my bedroom. I mentioned that he would have known about the issue if he had come by daily as mentioned. His reply was that he saw pictures every day. I explained that was not the same as coming by the actual site. The guy who did the work in my bathroom was good but I felt that I had to follow up on a lot of things. Since Paul was not around, I felt like I had to make sure he knew what was happening day to day. When they finished the plumbing, I had to have them come back twice due to leaks. They installed my medicine cabinet incorrectly and had to come back and fix it (it was not anchored on the wall). When they were "finished", I had to send an email with photos of a lot of little issues (dings in the wall, poor paint job, open edges where they did not caulk). They came back again to fix those items although now one section of a wall looks very odd (they sanded it and it has a different texture than the rest of the walls). At this point, I think I might hire someone else to come out and fix the wall/paint. I literally do not have it in me to go through another round of fixes. I had a few rough conversations with Paul about the project. During one of these conversations, he said "You have asked me the same question 4 times. If you keep asking me, you will keep getting the same answer." Not the response that I expected. He explained to me that "This is what happens in production." Funny enough - I work in manufacturing and production so did not appreciate that comment (although it has been the source of many, many jokes in my office). I explained that if he had done a better job pre-production (reviewing materials, reviewing construction expectations, etc.), we would not have had the issues during production. I also explained that I was asking questions because his answers were vague and not helpful. I got the impression he either didn't have the time to properly explain things to me or didn't think I could understand what was happening. One other point, because the guy who did the work in my apartment walked to my apartment, he didn't carry supplies. He ended up using my vacuum to vacuum up the dirt/caulk/etc and put the vacuum back. When I went to use my vacuum, it was filthy (absolutely covered in dust). When I picked it up, grout and white dust fell out. I asked him to clean it which he did - but it's still dirty. I will probably throw it away and buy a new. While I think Paul is qualified, I think he has too much on his plate. He told me that there are currently 30 projects going on. If he is going to be the Director of Projects, he should direct the team. If he is going to be a project manager, he should do that and be on site at the projects."

"They did the entire basement (complete perimeter "french drain", 2 sump pumps, etc). Al and his crew were phenomenal. Professional, clean (which is something for this type of work), and responsible. His crew came to work, knocking out everything in less than 2 days. I like to do things correctly and only once. While he was not the cheapest, his name says it all - it was done the RIGHT WAY. His services were second to none including the expert advice. The only company I will ever use and he is the only establishment you should consider."

Insulation questions, answered by experts

When planning an insulation service, account for the cold winters and humid summers in Flemington. Place vapor retarders on the warm-in-winter side of your walls to prevent condensation. If you live in the historic district, exterior modifications require special review. Address any outdated knob-and-tube wiring before adding insulation, as covering these wires violates NJ electrical codes and creates severe fire hazards.

Helpful?

Schedule your insulation service during late spring or early fall to avoid extreme Flemington winter temperatures that ruin spray foam performance. File for permits well in advance to prevent work stoppages during required inspections. Enroll in state energy rebate programs before the work begins to secure your incentives. Always verify that your local professional holds a valid NJ home improvement registration.

Helpful?

Before starting an insulation service, check with the local construction office to see if your project requires a permit. New Jersey enforces strict energy codes, so ensure your materials meet the required R-values for this climate zone. For older Flemington homes, test for asbestos before disturbing legacy materials. Schedule a home energy audit to identify existing gaps and prevent mid-project surprises.

Helpful?

A proper insulation service provides immediate comfort during sub-zero winters and scorching summers. You experience instant reductions in heating fuel consumption and qualify for state rebates. Over time, proper air sealing protects older Flemington structures from freeze-thaw moisture damage and prevents destructive winter ice dams. Energy efficiency upgrades also increase your property value and help meet NJ greenhouse gas reduction targets.

Helpful?

An insulation service drastically changes your home airflow. Tightening your home envelope reduces natural ventilation, requiring mechanical ventilation to maintain NJ indoor air quality standards. Upgraded insulation also reduces heating loads, meaning your current Flemington HVAC system will become oversized. Schedule a combustion safety test to prevent backdrafting risks with gas appliances, and ensure attic insulation never blocks your soffit vents.
