Deck builders in Burlington, MA

Homes in Burlington have a median construction year of 1972, so a deck original to a typical house would now be about 54 years old — beyond the point where wood framing, fasteners and flashing can be assumed sound.

Many decks from the 1970s and 1980s were built before today's detailed deck provisions appeared in model codes. Common issues on decks of this age include corroded hangers, posts set directly in soil and ledger boards fastened with nails. Replacement is often the better value than repeated repairs.

That makes Burlington's housing 10 years newer than Middlesex County as a whole, where the median home was built in 1962. Statewide, the median Massachusetts home was built in 1964. Among the 113 covered Massachusetts communities with Census data, Burlington ranks #87 for oldest housing. In this ZIP code, 30% of homes were built before 1960, 32% between 1960 and 1979, 14% between 1980 and 1999, and 24% since 2000 — the single largest group dates to the 1950s.

The nearest NOAA climate station with 1991–2020 normals is Reading, about 4 miles away. It records an average of 134 days a year with a low at or below 32°F — a substantial freezing season. On roughly 107 of those days the temperature climbs back above freezing, so water in wood, soil and gaps between boards repeatedly freezes and thaws.

For Burlington, 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 Reading station averages about 63.5 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.

Burlington sees about 50 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 12 days a year at 90°F or above — so board color can be chosen mostly on looks.

Budget, upkeep tolerance and sun exposure on your particular lot still decide the final choice between these options.

Burlington has about 10,371 housing units across its covered ZIP code. 71% are single-family detached homes, 3% are attached homes such as townhouses and rowhouses, and about 26% are in buildings with two or more units. Roughly 74% of occupied homes are owner-occupied.

The mix of detached homes and attached or multi-unit housing in Burlington means deck projects range from large backyard decks to compact rear decks on narrow lots. Lot size, neighbors' sightlines and any association rules shape the right design.

• Retrofit decks on older homes: about 4,902 homes (47%) 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 2,991 homes (29%) 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 1,568 homes (15%) 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.

Burlington 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 Burlington, 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. Statewide code background for Massachusetts is on our state page; local rules change, so the building department remains the authority.
