Deck builders in Bucks County, PA

Bucks County has about 257,260 homes, with a median construction year of 1975 (the Pennsylvania median is 1965). Within our covered ZIP codes — about 163,841 homes — the median is 1980, 5 years newer than the county overall.

Homes in the covered parts of Bucks County have a median construction year of 1980, so a deck original to a typical house would now be about 46 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.

Oldest housing: Buckingham (1938), Lumberville (1938) and Point Pleasant (1938). In these communities, expect retrofit decks on older houses and aging decks that need structural inspection, ledger and flashing upgrades, or replacement. Newest housing: Furlong (2002), Jamison (1992) and Warrington (1989). Here, projects lean toward enlarging builder-installed decks, adding stairs and railings, and upgrading to low-maintenance boards.

The nearest NOAA climate station with 1991–2020 normals is Doylestown AP, about 2 miles away. It records an average of 106 days a year with a low at or below 32°F — a substantial freezing season. On roughly 85 of those days the temperature climbs back above freezing, so water in wood, soil and gaps between boards repeatedly freezes and thaws.

For Bucks County, 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.

Snowfall is light — about 13.4 inches in an average year at Lambertville — so occasional ice is a bigger concern than snow load. Textured boards and good drainage on stairs help on icy mornings.

Bucks County sees about 47.7 inches of precipitation a year, with measurable rain or snow (0.1 inch or more) on about 78 days. Good drainage between boards, clean gaps and a ledger that is properly flashed keep that water from rotting the frame.

Average summer highs reach about 83°F, and around 20 days a year top 90°F. On a deck with full afternoon sun, dark composite can get uncomfortable on those days, so test samples in the sun before choosing a color.

• Replacement and major repair: about 111,325 homes (43%) 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.
• Retrofit decks on older homes: about 106,889 homes (42%) predate 1970. Here the priority is confirming that add-on decks are properly attached — or rebuilding them freestanding — before any cosmetic work.
• Upgrades and expansions: about 14,574 homes (6%) 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.

63% of Bucks County's homes are detached single-family houses and 16% are townhouses or other attached homes; 78% of occupied homes are owner-occupied. The sizable townhouse share means many elevated rear decks where re-staining is awkward, which tilts the value toward composite or PVC.

Pennsylvania's Uniform Construction Code applies statewide and is enforced by municipalities or third-party agencies they designate. Contact your township or borough. Before work starts, confirm with the building department for your exact address whether a permit is required, what drawings and inspections it involves, and whether an HOA must approve the design.
