Deck builders in Upper Falls, MD

Homes in Upper Falls have a median construction year of 1977, so a deck original to a typical house would now be about 49 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 Upper Falls's housing 4 years newer than Baltimore County as a whole, where the median home was built in 1973. Statewide, the median Maryland home was built in 1979. Among the 128 covered Maryland communities with Census data, Upper Falls ranks #41 for oldest housing. In this ZIP code, 37% of homes were built before 1960, 18% between 1960 and 1979, 45% between 1980 and 1999, and 0% since 2000 — the single largest group dates to the 1990s.

The nearest NOAA climate station with 1991–2020 normals is Aberdeen Phillips Fld, about 13 miles away. It records an average of 83 days a year with a low at or below 32°F — a moderate number of freezing nights. On roughly 73 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 Upper Falls 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.

Upper Falls sees about 51.1 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.

Average summer highs reach about 84°F, and around 26 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.

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

Detached single-family homes dominate in Upper Falls, 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.

For a deck project near Upper Falls, that county mix means you are as likely to be dealing with an aging deck that needs structural inspection before any resurfacing as with a new build. Ask your contractor to confirm the age and construction of your specific deck rather than relying on area averages.

• Replacement and major repair: about 41 homes (63%) 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 24 homes (37%) predate 1970. Here the priority is confirming that add-on decks are properly attached — or rebuilding them freestanding — before any cosmetic work.
