Deck Replacement in Gorham, Maine

A large share of Gorham's decks were built along with the town's 1980s, 1990s and early-2000s houses, and pressure-treated decks of that age are at or past the end of their service life. Warning signs include soft or cracked boards, wobbly railings, stairs that pull away from the frame, posts that have heaved on shallow footings, and a ledger nailed to the house without flashing, which lets water rot the band joist behind it. Many of those decks were also built to older rules on guard height, baluster spacing and ledger attachment.

Cardinal does not repair or patch decks; it takes the old deck down and builds a new one from the footings up. That means new footings below frost, a flashed and bolted ledger or a freestanding frame, new joists and beams, and code-compliant stairs and guards. The replacement is permitted through Gorham's Building Permit for Minor Projects, and a shoreland permit applies near the rivers. The new deck can be composite, PVC, pressure-treated or cedar, with a fixed-price written proposal from one of the owners.

Gorham counts about 6,800 housing units in the 2020 to 2024 Census estimates, with a median year built of 1988. Roughly a third of homes, about 33 percent, were built in 2000 or later, and about 29 percent date from the 1980s and 1990s, so most of the town's houses are under 45 years old. The older layer is substantial: about 14 percent of homes predate 1940 and about 21 percent predate 1960, including the wooden 19th-century houses of the Gorham Village historic district. Another 17 percent or so went up between 1960 and 1979. About 80 percent of homes are single-family detached and about 82 percent of occupied homes are owner-occupied. The estimates show essentially no seasonal housing, so nearly every house here is lived in year-round.

Permits in Gorham are handled by the Code Division of the town's Community Development department, and applications are now filed online through the SmartGov system. The town lists a Building Permit for Minor Projects that covers decks, sheds and pools, so a new deck or a deck replacement is permitted before construction; ask the Code Division whether a roofing, siding or window job needs one. Lots along the Presumpscot and other rivers fall under shoreland zoning and need a Shoreland Zoning Permit for work in that zone. Gorham also has a Historic Preservation Commission, which issues Historic Preservation Certificates for designated historic properties and districts.

Gorham is an inland town, about 200 feet above sea level, drained by the Presumpscot, Stroudwater and Little rivers, and out of reach of the salt spray that wears on coastal houses. What it does get is a full southern Maine winter. The Portland International Jetport, the nearest long-term weather station, averages close to 69 inches of snow a year, with seasons ranging from far lighter to far heavier. Nor'easters bring high winds and storms that often exceed a foot of snow, and roofs carry that load for weeks at a time. Spring and fall bring repeated freezing and thawing, which drives water into siding joints, window sills and roof edges, and heaves deck footings that were set too shallow.

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
