"Overall, very happy with the service.  Foamco installed foam insulation on two exterior walls and around the exterior sill plates in my basement.  The crew was on time and did a very good job.

"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."

"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."

"If anyone’s dealing with cold spots in their house — we just had our closet spray foam, and it made a huge difference. It was never insulated when we built, and now it’s finally warm. The crew was super professional, very neat, and honestly just a great group of guys. Highly recommend.!"

FAQs for insulation service projects in Mahwah, NJ

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.

It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.

Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
