Most of Hilliard was built during the suburban expansion of the 1990s and early 2000s, which means a large share of the city's homes are now 15 to 35 years old. Original decks from that era were almost always built with pressure-treated lumber, and those structures are now entering the period where serious problems appear. Central Ohio's freeze-thaw cycle hits from November through March - temperatures drop below freezing, moisture soaks into deck boards and framing, then temperatures rise and that moisture expands. Board fibers split, post bases rot where they are close to grade, and ledger connections loosen where flashing was not done correctly the first time. Homes in Hilliard's subdivisions built before 2005 often had ledger boards attached without proper waterproofing behind them, which is one of the most consistent repair issues we see in this part of Franklin County.

Hilliard sits on the same clay-heavy soils that cover most of central Ohio. Clay holds water instead of draining it, and the moisture level in that soil changes significantly between wet springs and dry summers. Those moisture swings cause the ground to swell and shrink, and footings that were not set to the correct depth below the frost line move with it. A post that has shifted even slightly out of plumb puts lateral stress on the ledger connection and the beam bearing points - the stress that leads to structural failure on older decks. The city's permit office requires footings to meet the Ohio residential building code frost depth, and we set every footing to those specifications regardless of how the original builder handled it.

Hilliard is a city of about 37,000 people in western Franklin County, sitting just west of Columbus along I-270. It grew quickly during the suburban expansion of the 1990s and 2000s as families moved out of the city looking for more space, newer construction, and strong schools. The result is a city that is largely made up of owner-occupied single-family homes - Colonial and traditional two-story styles dominate the subdivisions that spread out from the city's core. Most of those homes sit on lots of roughly a quarter acre, with attached two-car garages, concrete driveways, and fenced backyards. The Hilliard City Schools system is one of the primary reasons families choose to buy here and stay, which creates a community of long-term homeowners who invest in their properties.

The original downtown core - known as Old Hilliard - sits along Main Street and has a noticeably different character from the surrounding subdivisions. Older homes here were built in the early to mid-1900s and have wood clapboard siding, smaller lots, and construction details that differ from the newer builds elsewhere in the city. Neighboring Dublin to the north and Grove City to the south share similar housing vintages and climate conditions, so homeowners throughout this part of the Columbus metro deal with the same deck and fence maintenance cycle.
