"These guys were great. I had both my attic insulation upgraded, but also my home's crawlspace re-insulated. They were very respectful of my space, explained everything they were doing and answered all of my questions. They are a hard working customer oriented team. I would not hesitated to recommend this company to anyone."

"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."

"We have worked with many different contractors over the years and have been turned off of construction in general. None of our previous projects have ever gone smooth. The opposite can be said about home genius Exteriors! Joe was in communication with us throughout the project and made sure any issues and concerns we had were addressed immediately. This has been a really good experience and I highly recommend home genius Exteriors."

"I was dreading this work being done due to the anticipated mess since we had a drywall removed to have insulation blown into our attic. The process went fairly quickly. We also had drywall that was cut in our walls to have old insulation removed and new to be blown in. The crew did a lovely job of making the cuts so getting our drywall fixed afterwards was much more simple. All said and done, it wasn't nearly as unpleasant as I had feared. Highly recommend AGL Spray Foam."

"This company has made me feel safe and secure. I was unaware that 14 windows in my house did not lock. Now I can go to sleep with peace of mind. The salesman showed me everything and was thorough every step of the way. The install manager answered all my questions and the crew knocked it out the park and they are complete horses. Thank you so much victory."

FAQs for insulation service projects in Penns Grove, NJ

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
