Composite & PVC Decks 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.

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.

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.

Composite and PVC decking do not need staining, do not splinter, and resist rot, which is why they have become the default for new decks in Maine. Composite boards blend wood fiber and plastic under a protective cap; PVC boards are all synthetic and lighter. The North Deering farmhouse on this site got a rebuilt deck with AZEK composite decking. The framing underneath is still wood, so it is built to last as long as the boards on top.

• Layout, size and board color are chosen with the owner at the estimate visit.
• Footings and framing are built to code, with joist spacing that suits the board manufacturer's span rules.
• Joist tape or flashing protects the tops of joists and the ledger.
• Boards go down with hidden fasteners or color-matched screws and the expansion gaps the product requires.
• Matching railings, stair treads, fascia and landings finish the deck.

• You are done staining and sealing a wood deck every year or two
• The deck is in shade or near water where wood stays damp
• You want a deck that stays barefoot-friendly with no splinters

• Composite versus PVC, and the product line
• Deck size, height and shape
• Railing system and stairs
• Hidden-fastener versus face-screw installation
• Footing and framing conditions
