"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."

"Anthony Nastasi, hired by me to rebuild our decaying bay window, did a terrific job. When he came out to survey our prospective job, he listened closely to what we wanted, took notes, did measurements, and made suggestions. Later that day he sent my a proposal, detailing the materials and total cost of the project. Ultimately, the final cost was only about $300 more as additional material was needed. Mr. Nastasi worked a full day each day he was here. He also was honest and direct - he told me when he would arrive in morning, and he did. He told me when he had to complete another job so he might have to leave early or miss a day. Many Subs aren't professional enough to simply tell the truth. He always did. I am extremely happy with the quality of the work he did, the time frame in which he completed the job and, most importantly, how it looks. I would unequivocally recommend Anthony Nastasi to anyone.

"My bathroom remodeling experience was unexpectedly pleasant, and I owe a great deal of gratitude to the guys from Score Construction. I had a rough idea going in of what I wanted my mother's new bathroom to look like, but it was mostly just conjecture and hand-waving, needless to note I'm the type of guy who needs a gal that's mechanically inclined, because I'm far from it. Before starting the project, I had three contractors come and take a look at the bathroom (I also had two contractors who could only give me quotes over the phone, they were cheaper than the quotes I received in person, and I think it's very obvious why). They were all very professional in their conduct, but what set SCORE apart from the rest was their willingness to hear me out. I drew diagrams of what I wanted the bathroom to look like, and SCORE (in particular Janusz, though his partner was commendable as well) took the time to analyze my thoughts line by line. For my wishes that were feasible, they explained exactly how they would accomplish it, and for some of my ideas that were either too expensive or impossible considering the layout of the bathroom, they suggested revisions that were in line with the overall design (her bathroom is roughly 100 sq ft, so there was ample space for design). My only complaint about the other contractors was that they did not respect my ideas enough, not that they were rude in any way, but it felt to me as if the design was already established according to their desires, and it was me that was going to have to come around to their way of thinking. Admittedly, I have no design experience, but this is my project and my money so I figured that the hired hands should be a little understanding when it comes to my wishes. The guys at SCORE were more than understanding, and it showed itself in the final product. Once all the preliminaries were settled, the actual construction began and it was completed in two weeks. They adjusted their work schedule around my availability (if I was free and let them work straight w/o any days off I imagine it would have been done much sooner). They did a very professional job, and I'm very glad to have had such an easygoing remodeling experience. Mum's happy, so I'm happy. -Ali"

"Armor Insulation and More was timely, courteous, and efficient throughout the entire process. The owner went out of his way to make sure that I understood exactly the services I was to be receiving, and his team was nothing but respectful and left the house as clean as it was when they arrived. I would feel more than comfortable recommending them to family and friends."

FAQs for insulation service projects in Lawrence Township, 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.
