"⭐⭐⭐⭐⭐ Excellent Work by Sebastian – Jersey State Insulations We recently had insulation work completed by Jersey State Insulations, and Sebastian and his team did an outstanding job. From the beginning, Sebastian was professional, knowledgeable, and very easy to work with. He took the time to explain the process, recommended the right insulation for our space, and made sure everything was properly sealed and installed. The workmanship was clean, efficient, and done with great attention to detail. No shortcuts — just solid, quality work. Sebastian was punctual, respectful of our home, and left the area clean after the job was finished. We’ve already noticed an improvement in comfort. I highly recommend Sebastian and Jersey State Insulations to anyone looking for reliable and professional insulation services."

"Although I am pleased with the company & service provided overall (spray foam insulation), I was disappointed to find 17 bags of old insulation had been left in my yard! I was told it would be would hauled away when the job was complete. When I contacted the company, Dave advised it would be picked up...I'm still waiting ?"

"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."

"The insulation was added to the attic in a timely fashion. We are looking into insulating our walls with foam in the future and would definitely use Home Insulation Experts for this."

"Howard Falkow was incredibly helpful and responsive from the beginning.  He walked us through the analysis of the energy leaks in the house and outlined several options to help us save on our energy bill.  Rather than immediately pitch us on the most expensive option, he gave us an objective cost/benefit analysis as to which package would result in the best energy savings per cost.  
Howard was very responsive over email as well as on the phone and he and his staff were always friendly, professional, and very accomadating when it came to scheduling. 
Howard and NY Metro Insulation provide an excellent service for anyone who is looking to make their home more energy efficient.  They are honest, professional, and perform high quality work (we noticed results immediately after the work was performed) and I would recommend them very highly to anyone in the area.

"We had been living in our house for 5 years and although the kitchen was a new addition, every winter my wife & I had noticed how noticeably the temperature differentiated especially after the winter of 2014/15.  And because it was a dirt floor with some wood and old construction debris strewn about.  I was not so keen on staying down there.  In doing my own investigation there was some piping and insulation under floor.
So when investigating estimates we called a number of "green" companies.  Out of the three companies that came, only Frank Petrullo with Eco Green Solutions, noticed the mold and a water leak coming from fridge line.  He took the time to show me where the water was coming, how mold had proliferated on the wood floor joists and beams.  The dirt floor was somewhat moist and light was visible from outside along foundation rim contributing to the mold and moisture in crawl space.  He explained each of our options and detailed the steps in sections of each estimate.
We opted to have a plumber fix the water leak, then franks crew came in, cleaned up the mold, then layed down the crawl space membrane, finally insulating floor & rim joist.  All in under two days.  The crew showed up on time, left the open sections of the house clean, and we immediately noticed a difference in kitchen and rest of house.  Walking around bare foot in kitchen is more comfortable, the kitchen is less noisy, and house humidity is maintained.

FAQs for insulation service projects in Sussex, 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.
