The most expensive repairs we do every March were preventable every November. Winterization is us taking the freeze's side of the argument seriously.
A hot tub survives a Tri-Cities winter two ways: running, with freeze protection healthy — or properly shut down, with every line blown dry and antifreeze in the traps. The disasters live in between: the half-drained tub, the 'we'll deal with it after the holidays' tub, the tub whose freeze protection died with its circ pump in October and nobody knew.

We do both ends of the season. In fall, a full shutdown or a verified low-temperature hold; in spring, a start-up that checks what the cold did before the first soak — seals, unions, freeze-sensitive fittings, and the chemistry rebuilt from flat.
Full shutdown: drain, lines blown out, antifreeze placed, cover secured against wind.
Freeze-protection check: circ pump health, sensor sanity, and what happens at your tub when the power blips.
Call before refilling. Filling a freeze-damaged tub finds every crack at once, indoors and out.
Fill, pressure-watch, chemistry from scratch, heat-up test — surprises found before soak night.
Real faults, real fixes — the paperwork version, minus the addresses.
The tub sat half-drained through a freeze. The February winterization would have cost a tenth of the repair.
Lines were blown out and antifreeze set in November. Filled, balanced, heated — done in an hour.
