James Hardie Fiber Cement Siding in Kennebunkport, Maine

Census estimates put Kennebunkport's median home built around 1982, with about 13 percent of the housing predating 1940 and roughly 29 percent predating 1960, on a year-round population of well under 4,000 that swells considerably each summer. The town's defining houses are the early-1900s shingle-style cottages of the Cape Arundel Summer Colony, running from Chick's Creek toward Walker's Point, built as grand seasonal retreats rather than year-round homes. Cape Porpoise, the town's working fishing harbor, holds a more modest mix of older cottages and captain's houses, while Goose Rocks Beach and the town's inland areas add a range of newer, more ordinary coastal homes built through the second half of the 20th century.

Kennebunkport's whole coastline, from Cape Arundel to Cape Porpoise Harbor and Goose Rocks Beach, takes weather directly off the Atlantic: nor'easters bring storm surge and wind-driven rain, and salt air corrodes fasteners, flashing and metal roofing faster here than it does even a short distance inland. Winters bring the usual Maine freeze-thaw cycling, and the shingle-style summer cottages, many built with lighter framing meant for warm-weather use, need special attention to insulation and moisture control if an owner uses the house through a Maine winter. Coastal wind load also matters more here than in most of this service area, given how exposed Cape Arundel and Cape Porpoise are to open ocean.

Building permits in Kennebunkport go through the Planning and Development Department's Code Enforcement Office at Town Hall on Elm Street. With a population under Maine's 4,000-resident threshold, Kennebunkport is not required to enforce the statewide Maine Uniform Building and Energy Code, though the plumbing and general permitting process still applies to every exterior job here. Because the whole town sits on the coast, the Kennebunkport shoreline falls under Maine's Mandatory Shoreland Zoning Act, and the town maintains a separate Flood Hazard Development Permit for construction in shoreland and flood-zone areas, plus added review inside the Cape Arundel Summer Colony Historic District.

Fiber cement is a mix of cement, sand and cellulose fiber pressed into planks, shingles and panels. It does not rot, insects do not eat it, it will not burn, and factory-applied finishes hold color far longer than site-painted wood. It is heavier and more exacting to install than vinyl, which is exactly why installation quality shows. The Back Cove home on this site was re-sided with a complete James Hardie package of wood-grain plank.

• Walls are stripped, repaired and wrapped, with flashing at every opening and roof-to-wall joint.

• Trim, caulk lines and touch-up are finished so the pre-finished color stays uniform.
