What gets built

Excavation, septic,
houses on top.

Eight kinds of job, from a driveway cut to a finished house, across southern Maine, the New Hampshire Lakes Region and the Seacoast. Most of them end up on the same contract, because on a building job the ground and the structure have to agree with each other.

Pick the one you came for.

Each of these can be bought on its own. They can also be bought together, which is usually cheaper and always simpler, because the seam between the ground and the building is where a schedule slips.

Septic systems

Design through installation in York County and the New Hampshire towns next to it. Maine design starts at $700 and conventional work starts at $18,000. The system type comes from the site evaluation, not from a guess at the road.
