Deck builders in Lutherville Timonium, MD

Homes in Lutherville Timonium have a median construction year of 1976, so a deck original to a typical house would now be about 50 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 Lutherville Timonium's housing 3 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, Lutherville Timonium ranks #37 for oldest housing. In this ZIP code, 25% of homes were built before 1960, 29% between 1960 and 1979, 33% between 1980 and 1999, and 13% since 2000 — the single largest group dates to the 1950s.

The nearest NOAA climate station with 1991–2020 normals is Cylburn, about 6 miles away. It records an average of 92 days a year with a low at or below 32°F — a moderate number of freezing nights. On roughly 80 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 Lutherville Timonium 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.

Lutherville Timonium 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 18 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.
