Before the First Freeze

RV Winterization and Dewinterization

Upstate winters are mild until they aren't. One hard freeze can split a water line or crack a water heater tank or pump. We winterize at your driveway or storage lot, so you don't have to tow the rig anywhere.

When to Winterize Here

The first frost in South Carolina typically arrives in late October, earlier in the higher Upstate terrain. Greenville and Spartanburg average more than 40 days a year with freezing temperatures. If your rig is going into storage, book before the first cold snap, not after it.

Winterization, $250

  • Drain fresh, gray, and black tanks and the water heater
  • Blow out all water lines
  • Water heater bypass
  • RV antifreeze through every faucet, shower, and toilet, and into the drain traps
  • Appliance prep
  • Full systems check, so you know about problems before spring

Dewinterization, $175

We flush the antifreeze, put the water heater back in service, check for leaks under pressure, and confirm every system is safe and working before your first trip.

Have a generator? Ask about generator service at the same visit. A generator that sits all winter with old fuel is one of the most common spring no-start problems.
