"⭐⭐⭐⭐⭐ Excellent Work by Sebastian – Jersey State Insulations We recently had insulation work completed by Jersey State Insulations, and Sebastian and his team did an outstanding job. From the beginning, Sebastian was professional, knowledgeable, and very easy to work with. He took the time to explain the process, recommended the right insulation for our space, and made sure everything was properly sealed and installed. The workmanship was clean, efficient, and done with great attention to detail. No shortcuts — just solid, quality work. Sebastian was punctual, respectful of our home, and left the area clean after the job was finished. We’ve already noticed an improvement in comfort. I highly recommend Sebastian and Jersey State Insulations to anyone looking for reliable and professional insulation services."

"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!"

"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."

"They were fabulous. We could not have been happier with the work. They were so efficient and did such a great job. They cleaned up after themselves. They did an awesome job. I would recommend them to anyone!

We got 3 estimates to insulate approx 2500 sq ft of attic and install insulation in foundation crawl space. Howard from Metro gave us estimate of $4500 for 15" of cellulose insulation for the attic..that was twice the amount of insulation from the lowest estimate ( 7" + crawlspace $3000), but didn't include crawlspace. Highest estimate was approx $6,000 for 12"+ crawlspace. Howard from Metro said we would be better off with more insulation in attic and over garage then with less and insulation in crawlspace. He brought in at no cost to us, someone to do infrared scan of house for energy leakage. How was found to be tight but he recommended to better seal front door (I did myself). We went with Howard, crew showed up on time, did what they had to, very polite, clean. Oh...almost forgot...he also installed two ducts from bathroom exhaust fans that were vented into attic (no charge)...I was having that section of roof redone in spring and roofers attached vents in roof to ducts (went very smooth).  I would highly recommend Metro."

"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."

"Mark Group was great to work with, very knowledgeable, professional and responsive. We really got the sense that they were experts, and felt the most comfortable with their proposal and recommendations. Our 1950 ranch-style home developed significant mold in the attic, requiring a new roof/ventilation, mold removal and, as a final step, new insulation. Mark Group was very helpful in advising us about potential considerations with roof replacement in addition to the energy/insulation component they were focused on. The team did a terrific job, were very respectful of our home and property and completed the work in a single day.

Insulation questions, answered by experts

Selling a house with spray foam insulation can be challenging due to concerns about improper installation or its compatibility with the home's structure. If not applied correctly, spray foam can cause issues such as moisture buildup, cracking, or damage to wiring and plumbing. If the insulation didn't cure correctly, there are also flammability concerns. Removing or repairing this type of insulation can pose risks as well.

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise.
