"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"

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

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills. 

Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.
