Vinyl Siding Installation in Long Island, Maine

Census estimates count about 423 housing units, and the median year built is 1938. About 66 percent of units predate 1940, and about 68 percent predate 1960. Almost nothing was built between 1960 and 1979, only around 3 percent, and about 15 percent went up in 2000 or later. Roughly 95 percent of units are single-family detached houses, and about 88 percent of year-round households own their home. Seasonal use dominates: about 307 units, nearly three-quarters of the stock, are held for seasonal or occasional use. The town's comprehensive plan counts about 50 homes converted from year-round to summer-only use over a recent 25-year stretch and describes many summer houses as unheated or poorly heated. Many trace back to the summer-cottage boom of the 1890s and 1900s.

Long Island lies about six miles out from Portland along Hussey Sound, a main passage into the inner bay. Wind reaches it from every direction, and the town's comprehensive plan notes that the first settlers built on the south side of the island to shelter from northerly winter winds. Portland International Jetport, the nearest long-term station, averages about 69 inches of snow a season under the 1991 to 2020 normals. A January 2022 winter storm badly damaged the wave break, floats and pilings at Mariner's Wharf, and the plan lists sea level rise, stronger storms and upkeep of the island's bluffs among the town's concerns.

The Code Enforcement Officer meets by appointment through the Town Clerk. The town's building permit application covers new structures, additions, alterations, replacements and repairs, and it must include a scaled site plan and proof that a construction debris container has been delivered to be barged off the island. Every job gets at least three inspections: foundation, framing and final. Height is capped at 35 feet, and several zones limit structures to 15 percent of the lot. In the shoreland zone, new structures sit at least 75 feet from the upland edge of a coastal wetland, and the permit form warns that shoreland work may also need a Maine DEP permit.

Premium vinyl siding is the fastest way to a tight, low-maintenance exterior. Today's thicker panels come in clapboard, Dutch lap, board-and-batten and shake profiles and in colors that were not possible a generation ago. The projects shown on this site include CertainTeed Monogram vinyl siding, used to replace rotting wood clapboards and 1970s metal siding on Portland homes. Vinyl moves with temperature, so how it is hung matters as much as which panel you pick.

• Old siding is removed and the wall is checked for soft sheathing and past leaks.
• House wrap and flashing go on first, with extra care around windows, doors and roof-to-wall joints.
• Starter strip, J-channel and corner posts are set straight and level so every course lines up.
• Panels are nailed in the center of the slots and left loose enough to expand and contract through a Maine winter and summer.
• Trim is wrapped or replaced with low-maintenance millwork so there is nothing left to paint.

• You are tired of repainting wood clapboards every few years
• The existing vinyl is faded, cracked, or loose after wind storms
• The budget needs a whole-house result rather than one premium wall
• You want an insulated panel to take the edge off drafty walls

• Panel grade and thickness, and whether it is insulated
• Profile: clapboard, Dutch lap, board-and-batten or shake
• Amount of trim, soffit and fascia wrapped or replaced
• Tear-off and sheathing repairs
• House height and access
