Serving
Maine & NH.
We provide full-package ADU builds and excavation services across southern Maine, the NH Lakes Region, and the NH Seacoast — all within about an hour of our Newfield, Maine headquarters.
Our Service Radius
Langone Site Services is strategically located in West Newfield — on the Maine/NH line — letting us rapidly deploy equipment and crews across southern Maine, the Lakes Region, and the NH Seacoast.
Fast Deployment
We own our excavation fleet, so site prep starts the week we mobilize.
Local Expertise
We know the local soil conditions, zoning laws, and permitting requirements for every town we serve.
