Deck Replacement in Windham, Maine

Census estimates count about 8,700 housing units in Windham, with a median year built of 1985. Roughly 27 percent of homes were built in 2000 or later, and about 21 percent between 1960 and 1979, while only about 12 percent predate 1940. About 85 percent of occupied homes are owner-occupied and roughly 79 percent of units are single-family detached. Around 780 units are held for seasonal use. The town's 2017 comprehensive plan notes that many once-seasonal camps around the lakes are now lived in year-round, still reached by old gravel roads built for summer use. It also records that Windham's population held near 2,000 from 1830 to 1940, so most of today's houses belong to the decades of growth that followed.

Windham's Code Enforcement department, at 8 School Road, administers the town's land use, building, plumbing and electrical codes, and permits are applied for through the town's online portal. Decks are structural work, so check permit needs there before building one. Properties within 250 feet of Sebago Lake, Little Sebago, Highland Lake, the Presumpscot or the Pleasant River fall under shoreland zoning, which the town administers and which limits building near the water. Windham adopted a historic preservation ordinance in 1989, but its 2017 plan says no local historic district boundaries were ever put in place.

Windham sits inland, so salt spray is not the main enemy here; snow, cold and lake wind are. Homes on Sebago Lake near Jordan Bay face a long reach of open water, and the lake region is known for sudden weather changes in every season. Houses on Little Sebago, Highland Lake and the town's smaller ponds sit among trees that keep walls shaded and damp. The Portland Jetport, the nearest long-record weather station, averages about 69 inches of snow a year on 1991 to 2020 normals, with January lows near 16 degrees. Frequent thaws and refreezes through the winter push water into siding laps, roof edges and deck framing.

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
