Deck builders in Snellville, GA

The median home in Snellville was built around 1993. A deck built with a house of that age is now about 33 years old — the stage where first-generation pressure-treated decks commonly need major repair or replacement.

Decks built before 2004 were very likely made with CCA-treated lumber, which was phased out of most residential uses at the end of 2003. That doesn't make an existing deck unsafe, but old boards shouldn't be burned, and demolition debris should be disposed of according to local rules.

That makes Snellville's housing 3 years older than Gwinnett County as a whole, where the median home was built in 1996. Statewide, the median Georgia home was built in 1992. Among the 43 covered Georgia communities with Census data, Snellville ranks #18 for oldest housing. In these ZIP codes, 1% of homes were built before 1960, 17% between 1960 and 1979, 44% between 1980 and 1999, and 37% since 2000 — the single largest group dates to the 1980s.

The nearest NOAA climate station with 1991–2020 normals is Atlanta Peachtree AP, about 16 miles away. It records an average of 49 days a year with a low at or below 32°F — relatively few freezing nights. On roughly 47 of those days the temperature climbs back above freezing, so water in wood, soil and gaps between boards repeatedly freezes and thaws.

Frost is less severe in Snellville than in northern states, but footings still have to meet the local frost-depth requirement, and freeze-thaw cycles are enough to work loose nails and open checks in unsealed wood.

Snellville sees about 56.3 inches of precipitation a year, with measurable rain or snow (0.1 inch or more) on about 80 days. Good drainage between boards, clean gaps and a ledger that is properly flashed keep that water from rotting the frame.

Summers are hot: average summer highs are near 88°F, with about 53 days a year reaching 90°F or more. Surface temperature is a real consideration — lighter board colors, shade from the house or a pergola, and heat-mitigating composite lines are worth comparing.

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

Snellville has about 30,500 housing units across its covered ZIP codes. 90% are single-family detached homes, 2% are attached homes such as townhouses and rowhouses, and about 7% are in buildings with two or more units. Roughly 81% of occupied homes are owner-occupied.

Detached single-family homes dominate in Snellville, so most decks are backyard decks attached to the rear of the house. That gives more freedom on size, layout and stairs, and makes a well-planned deck one of the most-used rooms of the home.

• Replacement and major repair: about 18,162 homes (60%) 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 3,633 homes (12%) 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.
• Retrofit decks on older homes: about 1,012 homes (3%) predate 1970. Here the priority is confirming that add-on decks are properly attached — or rebuilding them freestanding — before any cosmetic work.

Snellville's milder winters — about 49 freezing nights a year — allow construction through most of the year. Peak summer heat (around 53 days at 90°F+) is the hardest time to apply stain or work in full sun, so many projects are scheduled for spring and fall.

For Snellville, GA, 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.
