"⭐⭐⭐⭐⭐ 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."

"Can I give them a 10 for value for the money? Dave, the owner, was great. Unbeatable price and they did a great job. I'm actually shocked by what a difference it makes. My house had no insulation in the walls and the furnace ran constantly. Now when I touch the walls, instead of being ice cold, they are room temperature, and the furnace barely runs."

"Acorn offered a professional and friendly survey, answering all of my questions and giving me their clear strategy to solve my problem. They came and left in one day, as planned. My AC turns off more often now, rather than having to stay on all day. I suspect this is due to my attic now being better insulated."

"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."

"RetroFoam of Michigan deserves more than five stars. The representative who gave me an estimate was prompt and professional. The office staff who called to tell me installers were ahead of schedule was kind and courteous as I answered during a busy day at work. The crew who came to insulate my garage was extraordinary. They made sure my garage was left clean. They even mopped the garage floor before they left! The crew leader explained the process of insulating with foam and exactly how the holes in my walls would be patched before the team left. I am an educator of 30 years and a licensed builder. I've remodeled and flipped homes and have rental units. I'm used to swinging a hammer alongside others. This company is made up of hard-working people who charge a fair price and do exceptional work. I have advice for those that run the company - take care of your installation crews! They are exceptional! If you've read this far and are interested in having your house/garage insulated give them a call now. You will be happy you did. Now...I'm looking forward to enjoying a warm man-cave garage on cold nights!"

"We couldn't be more pleased with Acorn's services. We had insulation blown in from the outside, as well as our attic done, and we feel a huge difference. The team that came to our house to do our insulation, Nate, Rajan and TJ, was the best! They were incredibly friendly, polite, and most importantly - thorough, both in the job that they did and also in tidying up. We can't say enough good things!"

"I have only glowing things to say about our experience using Home Genius Exteriors. From the thorough initial estimate and comprehensive inspection of the worksite and what the job would entail to the final bit of blown-in insulation, our multi-team project was completed to our satisfaction in a timely and professional manner. In the course of four days, we had a new roof, new trim, new gutters, and new insulation. Each part of the project required a different team. Each crew finished their task within the projected timeframe. Home Genius coordinated everything, including ordering and delivering the materials and arranging for the delivery and removal of the dumpster. Thanks to our Project Coordinator Ivan, every step in the process went smoothly. He arranged for workers to be at our home on consecutive days: we did not have any time in between steps waiting for availability of the next team. Ivan kept us informed of progress at every step of the way."

"I highly recommend this company for any type of insulation work. The salesman gave a very thorough presentation on all the available options for me, along with a rough estimate at the end of the meeting. I went with the option of removing & installing new rolled insulation (R30). The crew arrived on the scheduled installation date and got right to work. Sealed off everything properly, removed the old insulation, cleaned & cleared out the space, and then installed the new insulation. It was all completed in about 4 hours. I was very impressed."

Insulation questions, answered by experts

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.

A radiant barrier is a form of insulation topped with a reflective material designed to keep homes cool during hotter months. It is generally considered worth the investment if you live in a hot, sunny climate, as the cost can be recouped over time through lower energy bills. Installation costs typically range from $0.10 to $1 per square foot. After installation, homeowners in warm climates may save between $7 and $15 per month, potentially reducing their electric bill by 5% to 10%. The exact savings will vary depending on your location and the type of barrier chosen.

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

There are two reasons why cellulose insulation repels rodents (and insects). First, the insulation has been treated with boric acid, which is a natural pest-repellent. In addition, the loose-fill style of cellulose creates less-than-ideal conditions for mice and other rodents to nest and burrow, helping to keep them at bay.
