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"

THE START Turning Your Home Green, the insulation specialist, is a family business dedicated to making your living space a more comfortable, eco-friendly environment. My father started a residential renovation company in New Jersey 35 years ago. Over the years, almost every house he entered was inadequately insulated. He evaluated the living space and provided a solution to correct the problem.
"I DO NOT RECOMMEND! He was late to my appointment and very unprofessional upon arrival. He gave me an official estimate and when it was time to perform the work he backed out and told me he could not do it for the price quoted."

Servicing NJ/PA/DE At Master Attic, our goal is to provide you with the highest quality materials and workmanship at an affordable price. We are a team of licensed, trained professionals with 20+ years of experience in insulation and rodent solutions. May it be rodent proofing, insulation removal, insulation installation, sanitizing, moisture barrier, radiant barrier, air duct repair replacement, or crawlspace cleaning, we have you covered. Do you hear noises in the attic? Smell something in the crawl space!? Schedule an appointment today, and have one of our technicians come out to assess the area and provide a free detailed estimate for the project.
"Contacted Master Attic via Angi and Alex, the technician came to evaluate our attic and crawl space (2 separate spaces in our house). We heard critter noises and our upstairs was hot in the summer. The insulation was original to the ~30 year old house, so we know it's about time to get it done. Alex checked both spaces and showed us photos of problem areas. We have an estimate and Alex explained the details of the work involved. The team came within the week (we lucked out to take the spot of a cancellation), and everything was done as expected. There was a lot of work to remove old insulations, vacuum all debris, sanitize the space, seal all air gaps, install baffles, rodent proof, and install new insulation. The work was completed in around 6 hours, the spaces are now clean and tidy - quite unbelievable given how they were before. We went for the heavier insulation which is reflected in the project cost."

FAQs for insulation service projects in Dover, NJ
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
