Deck Replacement in Long Island, Maine

On houses this old, the deck is almost always a later addition, and many older pressure-treated decks are now reaching the end of their life. The warning signs are consistent: ledgers bolted to the house without flashing, which rots the rim behind them; posts on blocks or shallow footings that move with frost; nails and hangers corroded by salt air; and railings too low or too open for current code. When the structure itself is failing, patching boards only hides the problem.

Cardinal replaces decks from the footings up and does not do repairs, patching or staining. The old deck comes off, the house wall behind the ledger is opened and repaired where needed, and the new deck is built with flashing, frost-depth footings and hardware rated for salt exposure. Long Island's permit application covers replacement work, and because an attached deck is part of the principal structure, a larger replacement has to fit within shoreland setbacks and lot-coverage limits. The old decking leaves the island in the debris container the permit requires.

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.

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.

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.

When an old deck is soft, wobbly or pulling away from the house, a full replacement is treated as a new build: the old deck comes off, the footings and framing are built new, and the new surface, railings and stairs go on. That is the only way to deal with hidden rot at the ledger and frost-heaved footings, and it is how Cardinal Exteriors approaches it. It lets you change the size, shape and material at the same time.

• The existing deck is removed and disposed of, and the house wall behind the ledger is inspected.
• Rotted rim or sheathing behind the old ledger is repaired and the wall is flashed.
• New footings go below frost; new posts, beams and joists are framed.
• New decking, railings, stairs and landings are installed in the material you choose.
• Permits are pulled where required and the site is cleaned up.

• Soft or spongy boards and joists
• A ledger pulling away from the house or rust-streaked fasteners
• Posts that have heaved, leaned or rotted at the base
• Railings that wobble or are lower than today's code expects

• Removal and disposal of the old deck
• Repairs to the house wall behind the ledger
• New size, height and shape
• Decking and railing materials
• Footing type and site access
