Jersey State provides insulations such as: closed/open cell insulation, blown in insulation, sound and firestop insulation. We also retrofit houses for green and comfort energy. Family owned and operated. Business experience 15 years plus
"I can’t say enough nice things about Jersey State Insulation. Sebastian and his crew are absolutely amazing. They work very hard and are very conscientious of your home. When they did the insulation on my home they were very careful when moving things around and cleaning up after the job was done. Sebastian is very friendly and made every effort to explain everything and make sure I was happy with the work being done. I met with other insulation companies, but none seemed nearly as competent as Jersey State. The others wanted to charge me a lot more for something I didnt think I needed. The others though my problem was only the attic. Sebastian inspected the attic and said there was nothing it needed. Other contractors didn’t even want to attempt blow-in insulation, but Sebastian and his crew did it and the result is fantastic"

"WORST SERVICE ON THE MARKET. THIS COMPANY LEFT MY GRANDMOTHER $14k in DEBT, after recommending top teir gutters. The gutters were NOT needed. Not only did the company install the gutters poorly, they do not work. They do not work because she needs a roof, not new gutters. This horrible company recommended $14k gutters when a ROOF was needed. Now she will have to take down the gutters, and put up a new roof. KICKER - they fell into her garage door and left it damaged/non-functioning. DO NOT ..... I REPEAT ..... DO NOT USE THIS COMPANY. You can see in the pictures below how gutters should never have been installed on this house. Also can see how they do not work (icicles behind). Imagien $14k for gutters that do not work. RUN from Home Genius. Their response a week later: Ambrose Powell 1:45 PM (53 minutes ago) to Jeff, me, Austin, Victoria Bill, I respect that you are a busy person and that is exactly why I gave you a multitude of options for a scheduled phone call. After you agreed to talk at 9:30am I called you exactly at that time, you did not call me back until 11:50am in which you apologized for missing my call and told me you appreciated with me sticking with it. I too am a busy person and scheduled phone calls with other customers as well as additional meetings when you gave me the agreement of 9:30am. I can call you at 4:30pm if you are available or I can speak directly with your grandmother if you prefer.

Insulation services FAQs
When choosing a professional insulation installer, consider asking these questions to determine the best fit.
Will you address air leaks in my house?
Can you provide an R-value (heat resistance) fact sheet?
What kind of insulation will work best for my home?
How do you handle signs of a water leak?
Are you licensed and insured?
Can you provide customer references?
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.
In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:
High heating and cooling bills
Uncomfortable room temperatures
Ice dams on the edge of your roof
Roof leaks
Cold floors and walls
Freezing pipes
Temperature fluctuations
Visibly low insulation
Noise problems
Pest problems
On average, insulating an attic costs about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:
Blown-in: $1–$4 per square foot
Spray foam: $2–$5 per square foot
Batt: $2–$4 per square foot
Structural insulated panels: $4–$7 per square foot
Loose-fill: $2–$5 per square foot
Reflective: $0.50–$1.50 per square foot
