The conditions

What building on the Seacoast involves

Every region has its own failure modes. Ours come from salt, wind, water and the age of the housing stock.

Coastal wind and salt air

Portsmouth, Rye, Hampton, Kittery, York and Ogunquit sit in a harsher wind and corrosion environment than a house eight miles inland, so near the water we spec stainless fasteners, high-wind nailing patterns and a rainscreen gap behind the cladding. Vinyl serves fine on a sheltered lot in Barrington or Lee; within a mile or two of open water, fiber cement or engineered wood holds up better at a higher cost, and we will tell you which side of that line your house is on.

Old houses, and what is behind the walls

Dover, Portsmouth and South Berwick have some of the oldest housing stock in the country, and behind those walls we routinely find balloon framing, plaster over lath, knob and tube still energized, undersized panels and soft sills. All of it is workable: we probe before quoting, and anything that genuinely cannot be known until demo goes in the contract as a written allowance or exclusion.

Snow, ice dams and freeze-thaw

Roofs here get framed for town-by-town snow loads plus the drift load where a lower roof meets a taller wall, and footings and deck piers go below frost, roughly four feet, or they heave. Ice dams are a heat-loss problem, not a gutter problem: the fix is air sealing and insulation depth, with membrane at the eaves as the backup that keeps water out of your ceiling.

Permits, historic districts and shoreland review

Permits are issued town by town, and a part-time inspector or a planning board that meets once a month can set your start date, so we build that into the schedule up front. Historic district review in Portsmouth, shoreland rules within 250 feet of tidal water and designated rivers, and septic review on bedroom additions all come up here, and knowing which applies to your lot is part of the estimate.

Working across the state line

Kittery is minutes from Dover, but Maine has its own code adoption cycle, permit offices and trade licensing, plus sales tax on building materials that New Hampshire does not charge. The person writing the scope has to know which side of the river the house is on, and ours do.

Home base

Why Dover is the middle of the map

Dover sits at the hinge of this whole area. Route 16 runs north to Rochester and south to Portsmouth, Route 4 runs west through Durham and Madbury, and the bridges to Berwick, South Berwick and Eliot are minutes away.

That geography is the reason the service area looks the way it does. The showroom is a short drive from most of the map, and the towns on the list sit close enough together that getting to a site when something needs a decision does not burn the day in a truck.

See what we build

Don't see your town?

We are a Seacoast and southern Maine builder. If you are in Manchester, Concord, Portland or the Lakes Region, you are outside the radius where we can run a project the way we want to run it.

Just outside the list is a different conversation. In a neighboring town, a little further up Route 16 or up the coast past Wells, a full renovation or a new build can justify the drive; a single-room tile job usually cannot.

Ask about your town

Start with the site visit

Tell us the town and what you are planning. We will walk the property, tell you what the conditions there are going to demand, and put together a scope and a number you can hold us to.
