"⭐⭐⭐⭐⭐ 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 new roof installed on our Victorian house last winter, and the roofer told us that the very old insulation bats in our attic rafters did not allow for a proper vapor barrier, endangering the warranty of the new roof. The roofer referred us to an affiliated company that recommended removing all the old insulation bats and installing new insulation bats in the attic rafters with a proper vapor barrier. That would have been very costly and would done nothing at all to improve our level of insulation. Fortunately, I decided to consult with Acorn before going further, because they have a solid A rating on Angie's List (the 10% AL discount did not hurt either). I was impressed by Mike Sheehan's approach. He carefully measured the space between the old insulation and the rafters and concluded that there was a sufficient vapor barrier there. But he pointed out that the house was seriously under-insulated, as we already knew from our high heating bills. He recommended leaving the old insulation in place, blowing R-49 cellulose insulation into the attic floor, and installing insulation bats in attic crawl spaces that had no insulation. He said that the new insulation bats in the attic crawl spaces located in a semi-finished attic room would make our second-floor den (located directly beneath the semi-finished attic room) much warmer. After 35 years of suffering from the cold drafts in the den, I was skeptical to say the least, but I decided to go ahead with Mike's plan, which was about half as costly as the original roofing company's estimate for a great deal more insulation. The workers came and did the job on the appointed day in May.
We have central ac, and there was some improvement in our energy bill last summer, but nothing too extraordinary. But since Mike had told us that the real gains would come in the heating season, I decided to wait until the next winter to review Acorn in Angie's List. Well, this has been an exceptionally cold late autumn and winter so far in New Jersey, and the results have been truly amazing. For the first time in 35 years, our den is comfortable all the time, and the whole house is comfortable. The energy and cost savings have been dramatic. The heat just doesn't escape upward from the second floor anymore. Here is the most astonishing thing that happened. When the outside temperature got down to about 0 F. a few days ago (unheard of in this area), I heard a strange noise and realized that the central ac had gone on! The thermostat for the ac on the second floor was set to 76 or 77, and because the ground floor is not as tightly sealed now as the second floor, in the extreme cold the disparity between the thermostat for the house heat on the ground floor (set at 70 degrees) and the upstairs heat, normally about 1 or 2 degrees, had increased to 6 or 7 degrees because of the insulation!
In short, we could not be more pleased with the job that Acorn did or the investment that we made in insulation.

"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!"

"Atticare did a thorough evaluation of the home. Because the soffits were in disrepair, there was a pest issue. Atticare did a great job coordinating with the roofers. The old insulation was removed and the area was inspected for pests, cleaned and sanitized. They returned after the repair to make sure all was sealed, and installed the new insulation. They also helped lay down some plywood for some flooring in the space as an extra. Before doing their work, they laid down material to protect the floor and removed everything cleanly. They were efficient with their work and I was pleased with the job they did. The job was priced as quoted with no surprises. Marlon and Luis coordinated the job and were friendly, professional, and experienced."

Insulation questions, answered by experts

Blown-in insulation works, but only for unfinished attics. Also, it isn’t the longest-lasting nor the most effective option. For better options, look into spray foam insulation or natural fiber batts. They typically have a longer lifespan, better heat resistance, and stronger sound-proof abilities. Spray foam insulation costs about $1.25 to $1.50 per square foot, but can go up to more than $4 per square foot. Fiber batt pricing varies depending on the material.

Without a doubt, insulating a garage door is a surefire way to make your home more energy efficient. Not only does insulating your garage door reduce your electric bills, but it also helps protect your valuables inside your garage, all while making for a quieter interior space. 

In regions that drop below 0 degrees Fahrenheit, your car's battery is at risk of malfunctioning in a garage that drops dangerously low. So, homeowners who reside in extremely cold climates can especially benefit from insulating their garages.

The cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.

The amount of insulation you need will vary depending on where you live. Energy Star recommends certain minimum insulation values in different geographic regions. In most cases, however, even adding a little insulation is better than not adding any.

It is usually possible to install insulation yourself, but it’s often better to hire an insulation professional. An experienced insulation pro can determine which type of insulation is best for your space and the R-value get the most value and comfort in your home. Certain types of insulation can cause skin, eye, and lung irritation, and a professional will have the equipment necessary to keep themselves safe and limit the effect on your indoor air quality after the installation. Certain types of insulation—like blown-in and loose-fill insulation—demand a professional for proper functionality and safe installation.
