Deck Building in Gorham, Maine

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.

A new deck starts below ground. Footings have to reach below the frost line so the deck does not heave, the ledger that ties the deck to the house has to be flashed so it never rots the rim, and the framing has to carry snow as well as people. On top of that structure goes the part you see: composite and PVC boards, pressure-treated lumber or cedar, with railings, stairs and landings. Cardinal Exteriors builds new decks and full replacements only; it does not take on deck repairs or staining.

• An owner visits, looks at the yard and the house, and talks through size, layout, stairs and material.
• Permits are pulled where the town requires them.
• Footings are dug or set below frost; posts, beams and joists are framed to span and load.
• The ledger is flashed and fastened with structural fasteners, or the deck is built freestanding.
• Decking, railings, stairs and landings go on, with hidden or face fasteners to suit the boards.

• You want outdoor living space where there is none
• An existing deck is too small or poorly laid out for how you use it
• A new door, addition or view calls for a deck to reach it

• Deck size, height and shape
• Decking material: composite, PVC, pressure-treated or cedar
• Railing style and stair runs
• Footing type and site conditions: ledge, slope, access
• Permits and any shoreland or setback requirements
