"⭐⭐⭐⭐⭐ 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."

Metro NY Insulation is a green focused, cellulose insulation contractor that works with homeowners to help them save money on their heating and cooling costs. By sealing the home to prevent drafts from allowing heated (or cooled) air from escaping, home works more efficiently and uses less energy. We are accredited by the Building Performance Institute (BPI) for Building Envelope and Building Analyst to view the whole building as a system and allow it to breathe properly while still retaining the heat in the winter and the conditioned air in the summer. Proper ventilation and insulation leads to a healthier home, with fewer mold issues and less likelihood of developing ice dams in the winter. We do more than just add insulation, we do full scale weatherization to keep you and your home healthy. \n\nWe also do interior wall soundproofing to reduce noise transfer from room to room.\n\nWe use only 100% Borate infused National Fiber Cel-Pak so you won't have to worry about the toxic off-gasing or ammonia smell from inferior insulation used by other companies.\nAll employees are trained and trusted. NO SUBCONTRACTORS. Free in-home assessment. Costs are determined by the scope of the job - we do everything to the BPI specifications. \nWe do more than just insulate - WE WEATHERIZE!!!

Insulation questions, answered by experts

It improves energy efficiency, reduces noise, enhances indoor comfort, and prevents drafts by filling wall cavities.

Insulating your home's exterior walls can realize up to a 20% reduction in your monthly energy bills. This means that regardless of how much the project costs, it can begin to pay you back immediately. Additionally, adding spray foam and other high-end materials can increase the selling value of the property.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.
