"I wished if it were be able for me to give this company more than 5 stars for my review. Right after I realized that we have Raccoon residence in my attic I sent an email at midnight to Attic Fanatics. I got a call at 8 from Coby who said someone will come within a hour. Mike Bruer showed up on time and did a thorough inspection. He advised me that the Raccoon may have been in my attic for awhile. I decided to replace all insulation. He provided me a reasonable quote which I accepted right at the spot. He also helped me to file a claim with my homeowner insurance company. On the very next business day there was a crew of 5 people showed up on time. They are very professional and did a neat job. Being a picky person like me I am totally satisfied of their work. They sealed the openings to prevent the Raccoon from return. After they left I found out there is one Raccoon was still in the attic so they came back right away and chased it out then resealed the soffit vents with heavy gauge mesh. Great job!"

"I called PEC floors, based on their positive reviews on multiple "review" websites. I needed them tio do an epoxy/flake floor topping on my Brooklyn basement floor which was just old raw concrete. Their communication, Jonathan especially, was excellent, throughout the job. Even when unexpected problems in timing occurred, there was excellent communication from Shay. The issue was resolved and work was completed as originally scheduled. Their price was what I considered fair and the work was done on time, on budget and in a professional manner. The basement looks great. The color flake we chose was called "Cabin Fever", 2020 appropriate, LOL. Pics included. Thank you PEC."

FAQs for attic insulation installation projects in Mahwah, NJ

The best attic insulation depends on where you live, the project stage, and your budget. New builds often benefit from structural insulated panels for top-tier efficiency, while homes in very warm regions can see big cooling savings with reflective insulation. Blown-in, loose-fill, and spray foam all excel at filling odd spaces in finished attics. Talk with a certified local pro to match the material to your climate, space, and wallet.

You’ll only need a licensed electrician if the project calls for moving existing wiring or adding new fixtures. For straightforward insulation jobs, your insulation installer can work around current cables. That said, never start insulating until a pro has checked any questionable wiring. If you suspect damaged or outdated circuits, book an electrician first to keep the project—and your home—safe and code-compliant.

Without air sealing, even the best insulation can underperform. Gaps let heated or cooled air leak out, forcing your HVAC system to work harder and driving up energy bills. Sealing those cracks before adding insulation locks in conditioned air, keeps moisture at bay, and helps the new material hit its full R-value. Ask your insulation pro to tackle sealing first so you enjoy consistent comfort and lower monthly costs.

Among readily available options, structural insulated panels and rigid foam boards top the charts with R-values that can reach 8.0. They’re ideal for new construction or very cold climates where maximum thermal resistance matters most. If you live in a milder zone, blown-in or loose-fill insulation may deliver plenty of performance at a lower price. Weigh the upfront cost against energy savings—and lean on a local pro’s guidance—to pick the smartest fit.
