Siding Replacement in Cape Elizabeth, Maine

On this headland the south and east walls wear out first. Salt-laden wind drives rain behind lap joints and around window casings, and paint on older clapboard fails in the same bands every few years. Around 40 percent of the town's homes were built before 1960, so many walls carry original sheathing under two or three generations of cladding, and a full tear-off is the only way to see whether that sheathing, the corner boards and the sills are still sound before new siding goes on.

A whole-house replacement is also the moment to add a proper water-resistive barrier, flash every window and door head, and choose a material suited to how close the house is to the water. On a Shore Acres or Two Lights lot within sight of the ocean, fasteners, trim and flashing should be rated for coastal exposure. Because the Code Enforcement Office does not require a permit to replace siding, the homeowner is responsible for insisting on that detailing; an owner of Cardinal Exteriors measures the house and puts the scope in a fixed-price written proposal.

The Census Bureau's 2020-2024 American Community Survey estimates about 3,980 housing units in Cape Elizabeth, and roughly 90 percent of them are single-family detached houses. About 88 percent of occupied homes are owner-occupied. The estimated median year built is 1967. Close to 40 percent of the stock predates 1960, including about one in five homes built before 1940, and another quarter went up between 1960 and 1979. Only around 7 percent was built in 2000 or later, so most houses here are old enough to have outlived at least one roof and one round of siding. The older layer includes summer houses from the late nineteenth century, when Portland architect John Calvin Stevens designed Shingle Style cottages along the Casco Bay shore. The survey also counts roughly 210 seasonal units, homes that may sit closed through the winter.

Cape Elizabeth has almost no shelter from the sea. The land faces open ocean to the east and south, so wind off the Gulf of Maine arrives with salt spray and nothing to break it, and nor'easters push rain sideways into siding joints, window heads and roof edges. Portland, just to the north, averages about 69 inches of snow a year, with large swings between winters, and storms that bring a foot or more are a regular part of the season. The ocean moderates temperatures near the shore, which means more winter days that hover around freezing and more freeze-thaw cycles on shingles, flashing and deck footings. Fog and damp air keep north-facing walls and shaded roofs wet longer than inland houses see.

Permits run through the Cape Elizabeth Code Enforcement Office, 320 Ocean House Road, which has accepted building applications online since May 2025. Its FAQ states that a building permit is required to construct, structurally alter or enlarge a structure, and that no permit is required to replace siding or roofing. A new deck needs a building permit. The town's Shoreland Performance Overlay District covers land within 250 feet of tidal waters, Great Pond and the Spurwink River, with a 75-foot setback for new structures from most water bodies. Resource protection permits go through the Planning Office, and work in a mapped flood zone needs a Flood Hazard Permit.

Siding replacement is more than new cladding. The old siding comes off, the sheathing underneath is inspected and repaired where it has gone soft, a new weather-resistive barrier and flashing go on around every opening, and the new siding and trim are installed as one system. In Maine, where wind-driven rain, freeze-thaw cycles and long winters test every seam, the layers you never see decide how long the wall lasts.

• An owner walks the house, measures every wall, and notes rot, past leaks, and how many layers of old siding are on it.
• Old siding and trim are stripped to the sheathing, and damaged boards are cut out and replaced before anything new goes on.
• A house wrap or other weather-resistive barrier is lapped shingle-style, with flashing tape and head flashing at windows and doors.
• New corner boards, window and door casing, and frieze trim go up, then the siding itself, fastened to the manufacturer's spacing.
• Debris is hauled away, magnetic sweeps pick up nails, and the job is walked with you before the last crew leaves.

• Clapboards or shingles that are cupped, split, or soft when pressed
• Paint that peels within a few seasons of being painted
• Stains, mold, or bubbling paint on interior walls after storms
• Dated aluminum, asbestos-cement or 1970s metal siding you want gone
• Rooms that feel drafty along exterior walls

• Wall area and how many stories need staging or lifts
• How many layers of old siding come off, and whether any need special handling
• Sheathing repairs found once the old siding is off
• The siding material chosen: vinyl, fiber cement, cedar or composite
• Trim detail: corner boards, window casing, frieze boards and brackets
• Whether windows or the roof are replaced in the same visit
