What We Do
Insulation Services
We specialize in retrofitting existing homes — bringing your insulation up to modern standards with minimal disruption.
Closed-Cell Spray Foam
Our primary specialty. Closed-cell spray foam is the highest-performing insulation available — it seals air leaks, adds structural rigidity, and delivers superior R-value per inch. Ideal for attics, crawl spaces, rim joists, and hard-to-reach areas in existing homes.

Open-Cell Spray Foam
A flexible, cost-effective spray foam option ideal for interior walls, attic rafters, and sound dampening. Open-cell foam expands to fill every cavity, providing excellent air sealing and thermal performance at a lower cost per square foot.

Blown-In Attic Insulation
We blow cellulose insulation into attics to bring them up to optimal R-value quickly and with minimal disruption. Cellulose is eco-friendly, fire-resistant, and fills every gap for consistent coverage.

Attic Air Sealing
Before insulating, we seal attic bypasses — gaps around pipes, wires, and framing — to stop conditioned air from escaping. Air sealing multiplies the effectiveness of any insulation upgrade.

Crawl Space Insulation
Cold floors and moisture problems often start below. We insulate crawl spaces with closed-cell spray foam to eliminate drafts, block moisture, and improve comfort throughout the home.

Exterior Wall Insulation
We blow cellulose into existing exterior walls without major demolition — a cost-effective way to dramatically improve your home's thermal envelope and reduce drafts.

What Our Customers Say
Riggs Langdon

"Hugo and the whole team did a phenomenal job. They came in and did exactly what they said they were going to at the agreed price. They were efficient and more importantly kind. Highly recommend them"

"During a renovation project of a 1950's colonial house....Hugo and his crew blew insulation into my plaster walls. Where the walls were opened up they used spray foam, and spray foamed the attic and basement rim joist. My house is energy efficient and comfortable. I deferred to Hugo for his expertise and was beyond pleased at the end result. I continue to refer Hugo and New York Energy to anyone that asks about insulation. Highly recommend!!"

"The guys did closed cell foam in my crawl space, and dense packed cellulose around the house. They're super clean and efficient - the house used 30% less oil from one winter to the next, I haven't even done the roof yet! More savings to come. Highly rec this improvement to your home. Check out my before and afters."

"I can say that the result of having my attic insulated by NYEC was obviously worth it. We use less heating oil and our house is more cozy/attic is more accessible all year. What I would like to really express is how smooth and easy the process was. Hugo answered any and all questions I had and his crew were very professional. Would recommend to anyone who is on the fence about getting their home spray foam insulated."

"While replacing a deck, we noticed the fiberglass insulation on an adjoining addition was falling down. As we were getting ready to close up the only access to this area we needed someone to come out fast. Despite their busy schedule, they came out on a Sunday to knock this small job out for us so we could close up the deck. Very happy with the job and speed."
