"I can’t say enough nice things about Jersey State Insulation. Sebastian and his crew are absolutely amazing. They work very hard and are very conscientious of your home. When they did the insulation on my home they were very careful when moving things around and cleaning up after the job was done. Sebastian is very friendly and made every effort to explain everything and make sure I was happy with the work being done. I met with other insulation companies, but none seemed nearly as competent as Jersey State. The others wanted to charge me a lot more for something I didnt think I needed. The others though my problem was only the attic. Sebastian inspected the attic and said there was nothing it needed. Other contractors didn’t even want to attempt blow-in insulation, but Sebastian and his crew did it and the result is fantastic"

"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!"

"We couldn't be more pleased with Acorn's services. We had insulation blown in from the outside, as well as our attic done, and we feel a huge difference. The team that came to our house to do our insulation, Nate, Rajan and TJ, was the best! They were incredibly friendly, polite, and most importantly - thorough, both in the job that they did and also in tidying up. We can't say enough good things!"

FAQs for insulation service projects in Lake Hopatcong, 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.
