Spray Foam Insulation Near Brewster, NY
If you're searching for spray foam insulation near me in the Hudson Valley, you're talking to us. Liquid Green is headquartered in Brewster — 473 Rt 164, right off I-84, a mile from the Brewster Metro-North station. Our crews leave the shop every morning and spray homes and commercial buildings across Putnam, Dutchess, and northern Westchester counties.
Being local means faster quotes, faster response, and crews who know the housing stock, the building codes, and the climate. The Hudson Valley sits in IECC climate zone 5 (with pockets of zone 4 and 6), so we size every job to meet or exceed the local R-value requirements — which have only gotten stricter with the 2020 IECC update.

What We Install in This Territory
Our Hudson Valley crews run the full residential and commercial spray foam catalog:
Residential — the bread and butter
- Attic encapsulation — open cell over the floor deck, or closed cell on the underside of the roof deck. Most common Hudson Valley job. Stops ice dams, kills the stack effect, brings attics inside the conditioned envelope.
- Rim joists — the #1 air-leakage location in most homes. Closed cell, ~3" thick. Knocks 10-15% off heating bills by itself.
- Cathedral ceilings and bonus rooms — spray between rafters where conventional batts leave gaps and air leaks.
- Basement walls — closed cell against poured concrete or block, with a thermal and moisture break. Code-compliant for habitable basement conversions.
- Crawl spaces — encapsulated with closed cell on the walls, vapor barrier on the floor. Turns a vented crawl into a conditioned one.
- Whole-home retrofits — exterior wall injection (we open the siding or drill through the sheathing) for older homes without wall insulation.
Commercial
- Metal building and pole barn insulation (the dominant commercial ask in our territory)
- Warehouse and agricultural structure insulation
- New-construction residential subdivisions — we contract directly with builders
- Commercial retrofits and tenant fit-outs
For commercial, our commercial guide covers the differences from residential work in more depth.
Why Hudson Valley Homeowners and Builders Choose Liquid Green
Local crews. Same training, same equipment, same standards on every job. Open cell and closed cell from the same chemical systems other top-tier operators use. Class 1 fire rating on every install. Quotes that show up when we say they will.
We also know the local housing stock. Pre-war colonials in Poughkeepsie. Capes and ranches from the 60s-80s throughout Putnam County. New-construction subdivisions in Yorktown and Somers. Brownstones and Victorians in Beacon. Each housing type has its own insulation challenges, and we've worked on all of them.
What Spray Foam Insulation Costs in the Hudson Valley
Per-square-foot pricing in our territory runs in line with the broader tri-state market. New-construction open cell typically prices at the lower end; retrofit closed cell in existing walls or rim joists prices higher because of the prep work. For the detailed pricing breakdown, see our cost per square foot guide.
The right way to get a real number is a quote. We come out, measure the assemblies you want sprayed, and give you a written estimate. Most quotes are scheduled within 48 hours of your call.

Local Building Codes & Climate
Hudson Valley homes fall under the New York State Residential Code, which adopts the 2020 IECC. Climate zone 5 (with some 4 and 6 pockets) drives the following minimum R-values for spray foam:
- Attic — R-49 to R-60 (zone 5); R-60 in zone 6
- Wood-frame wall — R-20 to R-30 cavity + continuous, depending on zone
- Floor over unconditioned space — R-30
- Basement wall — R-15 continuous for habitable basements
- Crawl space wall — R-15 continuous, plus vapor barrier on the floor
These are the floors. We typically recommend hitting slightly above the code minimum to capture the air-sealing bonus that makes spray foam worth the premium in the first place. R-value explained covers the science.
