"We got a couple of estimates to spray the cellar sills where the house meets the foundation. We chose Foamcoinc because of the knowledge of the person that came and gave us an estimate...I think his name was Dave. He had some good ideas on how to spray and seal under the bay windows, left samples of the foam with us, and some more information. I thought that was great so I could make a more informed decision. Not to mention the 'R' value of the foam he would use was much higher than the other company's and he price matched the other company's price in his estimate! They showed up about a half hour early, which was slightly inconvenient. Thank goodness my husband was home since I just got out of the shower when the doorbell rang. They came in and went right to work. They did everything they said they were going to do and a bit more than expected. The thickness of the spray insulation was thicker than they specified and they were neat and clean! A great experience! Try them out for yourself! I will be calling them for when I am ready to do the attic."

"We had a freezing bedroom in our house as well as a freezing entry way. Turns out it was above the garage with zero insulation. Mike came out and from the start understood what was creating the issue. Not only he is highly knowledgeable about home construction in general, he was an absolute pleasure to work with and hilarious! The team at Acorn was able to schedule us in 2 days before Christmas. If you were in the North East around Christmas 2022, you experienced that deep freeze that came through. If you want to know if your home was insulated right, nothing like freezing temps to show you. Acorn did a thorough and professional job and installed blown and fiberglass insulation. Our room was toasty with no indication of how cold it was outside. I cannot thank them enough!"

"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."

"The job was very well done. Gustavo and his crew were EXCELLENT. Dealing with the project Manager Taylor was EXCELLENT. One of a kind company. A unique feature that was used for installation was the inclusion of BOTH Sanford insulation and housewrap. I have not had another contractor offer me both of those. It’s always either one or the other. Home Genius is backed by the better business bureau and is a James Hardie certified installer for those looking for one."

FAQs for insulation service projects in Caldwell, 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.
