Deck builders in Quincy, MA

The median home in Quincy dates to about 1958, roughly 68 years ago. Most homes from that era were built without a deck; the decks you see now were usually added in later decades, sometimes by previous owners with little documentation.

That history matters: retrofit decks are where missing ledger flashing, undersized footings and nailed-rather-than-bolted connections are most common. Before resurfacing or extending an add-on deck, it is worth confirming how it was framed and attached.

That makes Quincy's housing 6 years older than Norfolk County as a whole, where the median home was built in 1964. Statewide, the median Massachusetts home was built in 1964. Among the 113 covered Massachusetts communities with Census data, Quincy ranks #50 for oldest housing. In these ZIP codes, 52% of homes were built before 1960, 17% between 1960 and 1979, 14% between 1980 and 1999, and 17% since 2000 — the single largest group dates to the before 1940.

The nearest NOAA climate station with 1991–2020 normals is Hingham, about 5 miles away. It records an average of 115 days a year with a low at or below 32°F — a substantial freezing season. On roughly 94 of those days the temperature climbs back above freezing, so water in wood, soil and gaps between boards repeatedly freezes and thaws.

For Quincy, that means footings must bear below the locally required frost depth to avoid heaving, and wood surfaces should be kept sealed so absorbed water doesn't split boards over winter. Synthetic decking tolerates freeze-thaw well but still needs the manufacturer's expansion gaps.

Snow is a major factor: the Hingham station averages about 50.9 inches a year. Framing has to carry snow load, stairs need a plan for winter use, and snow removal should be done with plastic-bladed shovels and ice-melt products the decking manufacturer allows.

Quincy sees about 52.3 inches of precipitation a year, with measurable rain or snow (0.1 inch or more) on about 84 days. Good drainage between boards, clean gaps and a ledger that is properly flashed keep that water from rotting the frame.

Summer heat is mild by comparison — average summer highs near 81°F and only about 13 days a year at 90°F or above — so board color can be chosen mostly on looks.

Other Quincy factors: older homes often suit traditional wood or a wood-look composite. On Quincy's many older homes, a wood-look capped composite or a stained cedar deck usually suits the architecture better than high-gloss boards.

Quincy has about 48,045 housing units across its covered ZIP codes. 33% are single-family detached homes, 5% are attached homes such as townhouses and rowhouses, and about 62% are in buildings with two or more units. Roughly 45% of occupied homes are owner-occupied.

Because so much of the housing in Quincy is multi-unit, a meaningful number of decks and balconies are governed by condominium or building associations. For single-family homes and townhouses here, check whether any association rules apply before you design.

Because fewer than half of homes here are owner-occupied, rental property owners make up a share of deck decisions here; durable, low-maintenance materials often make sense for them.

• Retrofit decks on older homes: about 27,899 homes (58%) predate 1970. Here the priority is confirming that add-on decks are properly attached — or rebuilding them freestanding — before any cosmetic work.
• Replacement and major repair: about 11,884 homes (25%) were built between 1970 and 1999, the age group whose original or early add-on decks are most likely to have worn-out framing, connectors and boards.
• Upgrades and expansions: about 5,210 homes (11%) were built since 2010. Their decks are usually sound but small or builder-grade, so enlarging the deck, adding stairs and switching to composite or upgraded railings are common.

Quincy has a defined building season. Spring and early fall offer the most comfortable working weather; winter is a good time to settle the design and apply for permits. Stains and sealers generally need dry weather and moderate temperatures, so plan wood finishing for late spring or early fall.

For Quincy, MA, ask the permit office whether your deck needs a permit based on its size, height and attachment to the house, which drawings and inspections are required.
