Who is an excavation contractor in southern Maine and York County?
Langone Site Services is an excavation contractor based in West Newfield, Maine. We work southern Maine and York County, including towns like Sanford, Alfred, Limerick, Shapleigh, Acton, Waterboro, Newfield, the Kennebunks, and Wells.

No. The excavators, dozers and dump trucks belong to the company, which means a job is not held up waiting on a rental or on another contractor to finish with a machine.
Do you also install septic and do site work?

Land clearing, bulk earthmoving, stump removal, rock removal, cut and fill, and final grade. We also handle foundations and drainage, road and driveway work, utility trenching, and municipal and road work.
Who does the site work?
The crew that starts the site work finishes it. The excavators, dozers, dump trucks and operators belong to the company, so your schedule does not depend on a rental yard or another contractor's calendar.
Do you do driveways, roads, and utility trenching?
Yes. That includes new driveway cuts, road grading, culvert installation, and base material prep. Utility work covers trenching for water, sewer, power, and fiber, plus water line installs, sewer lateral hookups, electric trenching, and underground utility boring. We coordinate with the local providers.
Do you take municipal or commercial site work?
Yes. We do municipal and road work, and commercial site work for subdivisions, commercial lots, and industrial pads. That also covers retention ponds, swales, and stormwater. Ask about the insurance certificate on file, and ask whether a specific project can be bonded. Limits and bond amounts aren't published.
Can you build the house or ADU after the site work?
Yes. Turn-key ADUs and custom homes, with the site work included in the same contract rather than quoted separately. ADU models start at $147,000. Custom homes start at $325 per sq ft, land extra.
How much does an ADU cost in Maine or New Hampshire?
Langone Site Services publishes 10 turn-key ADU models from $147,000 to $388,000, built in southern Maine, the NH Lakes Region, and the NH Seacoast. The Bean is $147,000 for 384 sq ft. The Wakefield is $216,000 for 525 sq ft. The Newfield is $196,000 for 600 sq ft. The Summit is $235,000 for 654 sq ft. The Bentley is $278,000 for 750 sq ft with an attached garage. The Shapleigh is $252,000 for 800 sq ft. The Spruce is $290,000 for 882 sq ft. The Washington is $305,000 for 896 sq ft. Ella's Retreat is $321,000 for 981 sq ft. The Ossipee is $388,000 for 1,049 sq ft with a 2-car garage. Ella's Retreat and The Ossipee need a town that allows that size. On a standard lot, site prep, foundation, utilities, septic hookup, and finish are included. Site conditions and town tap fees can change the number. Custom homes are a separate product and start at $325 per sq ft, land extra. Call (978) 987-0089 for a number against your own lot.
Are ADUs legal in Maine and New Hampshire?
Yes. Maine LD 2003 still requires towns to allow at least one ADU on a lot with a single-family, two- or three-unit home. LD 1829 (signed June 20, 2025) and LD 2173 (signed April 16, 2026) add density rules and limit fire-sprinkler mandates on buildings with two or fewer dwelling units. Maine's ADU rules took effect for towns on January 1, 2024 where the selectmen can amend the ordinance on their own, and July 1, 2024 everywhere else, and some towns are still catching up. New Hampshire HB 577 (effective July 1, 2025) requires one ADU by right in single-family districts, and the town must permit a detached unit and bars a maximum size below 750 sq ft. Setbacks, septic, and shoreland still apply. We read your town's ordinance on the consult.
How long does an ADU take?
We don't publish a fixed completion promise. Permits, utilities, and the lot decide the schedule. Ask for a timeline on your site.
Who does the excavation and septic work?
Site work and septic are part of the build rather than a separate contract to arrange. Conventional septic in Maine starts at $18,000. Maine design starts at $700. Plumbing and electrical are scheduled and managed as part of the build, so you are not chasing trades.
What towns do you serve?

If your town isn't on the service-area page, call and we'll say yes or no.
Do you build ADUs in the NH Lakes Region and on the NH Seacoast?
Yes. We build turn-key ADUs in the NH Lakes Region, including Meredith, Gilford, Wolfeboro, Ossipee, Alton, and Laconia, and on the NH Seacoast, including Portsmouth, Exeter, Hampton, Rochester, Dover, and Durham. The same 10-model catalog applies. Call (978) 987-0089 if you want to check a specific town.

Do you build custom homes in West Newfield and nearby towns?
Yes. We build new and custom homes in West Newfield and nearby towns across southern Maine, the NH Lakes Region, and the NH Seacoast. New and custom homes start at $325 per sq ft and go up from there. Land isn't included. Site work and the house sit under one contract. We don't publish a four-tier price table.
Do you build on a fixed price or on cost-plus?
Both, depending on how settled the design is. When the plan and the specification are defined well enough to price properly, we give a fixed price and we carry the risk if it costs more than we expected. A fully custom house, where the selections move outside the brands and finishes we work with as standard, is usually built on cost-plus: you pay the documented cost of labour, materials, and subcontractors plus a builder's fee, either a fixed amount or an agreed percentage of cost, settled in writing before work starts. Cost-plus is open-book, so you see the invoices behind every line, and you don't pay for contingency that was never used. The trade-off is that the final number isn't known on the day you sign, which is why we set a detailed budget, allowances for undecided selections, a written change-order process, and regular cost reporting at the start.
How much does a custom home cost per square foot?
New and custom homes start at $325 per sq ft. Land is extra. We don't publish a four-tier price table. Ask us for a number on your lot and plan.
Do you build new homes in the NH Lakes Region and on the NH Seacoast?
Yes. We build new and custom homes in the NH Lakes Region, including Meredith, Gilford, Wolfeboro, Ossipee, Alton, and Laconia, and on the NH Seacoast, including Portsmouth, Exeter, Hampton, Rochester, Dover, and Durham. The starting price is the same: $325 per sq ft, land extra. Call (978) 987-0089 to check a town.
What does Langone handle on a custom home?
Land review before you buy, excavation, drainage and erosion controls, foundation and utilities, the full home build or a major addition, and garage and studio buildings, all on a single contract.
