Tampa Heights sits between the river and downtown, and its early twentieth-century wood-frame homes are among the oldest housing the company works in. Water heaters here are frequently squeezed under a stair, into a rear porch enclosure or behind a kitchen wall, which changes both the diagnosis and the removal route.
Wood-frame construction also means a slow leak does not behave like it would on a block wall. Water travels along joists and shows up somewhere other than the heater, so tracing a stain back to the unit is part of the visit rather than an assumption.
Access is the other factor. Replacing a tank in a hallway closet means protecting floors, planning the turn at the door and having enough hands for the weight. None of that is unusual; it just needs to be planned before the old unit is disconnected.
Alley access matters here. Several blocks were laid out with service lanes behind the houses, which makes bringing equipment in and taking a failed tank out far easier than the narrow front doors suggest. Where there is no alley, the route through the house is planned in advance and floors are protected before anything heavy moves.
