Job sizes

Minor

A single quick task, like blowing out and adding antifreeze to the water lines on a small travel trailer, or a simple de-winterize and flush.

Standard

A full winterize or de-winterize on an average rig, covering water lines, pump, water heater bypass, low point drains, and traps, often with a basic once-over.

Major

A larger motorhome or a rig with an ice maker, washer, second bathroom, or added plumbing, plus a full seasonal inspection of roof, seals, tires, and batteries.

Replacement

Repair work after a freeze, such as replacing cracked pipes, fittings, a burst pump, or a split water heater tank, priced as a repair on top of the service.

Final pricing comes from the on-call provider after on-site assessment, with a written estimate before any work starts.

What to expect

✓A good pro uses RV-safe, non-toxic antifreeze rather than automotive antifreeze, which is toxic and not made for drinking water lines.
✓They bypass the water heater before adding antifreeze, which protects the tank and keeps you from wasting gallons of antifreeze.
✓They drain the low point lines, water heater, and holding tanks and open the faucets so trapped water cannot freeze and split a pipe.
✓On de-winterize they flush the system and sanitize the fresh water tank so the water is safe to drink again.
✓They will tell you honestly whether your rig needs winterizing based on how long it will sit and the weather, instead of upselling work you do not need.
✓A thorough tech checks for existing leaks and cracks while the system is drained, so small problems get caught before the next cold snap.

Look for general liability insurance, RVIA or RVDA training or an RVTI-trained technician, and manufacturer or appliance certifications for water heaters, furnaces, and LP systems. Mobile techs should be comfortable working on your specific rig type, whether a travel trailer, fifth wheel, or motorhome.

Common questions

Does an RV really need winterizing in South Texas?

South Texas is mild most of the year, but the Coastal Bend still gets hard freezes and cold snaps. Even a few hours below freezing can crack a water line or pump. If the rig will sit unused during a cold stretch, or you are heading back north, protecting the water lines is cheap insurance against an expensive repair.

What is the difference between winterizing and de-winterizing?

Winterizing means draining the water system and adding RV-safe antifreeze so nothing freezes and cracks while the rig sits. De-winterizing is the spring step: flushing that antifreeze out, sanitizing the fresh water tank, and checking for leaks so the water is safe to use again.

Can a pro come to my RV park or lot instead of me driving somewhere?

Yes. Many RV techs are mobile and come to your site at the park, storage lot, or driveway. This is handy for Winter Texans who are already set up and do not want to break camp. Ask if they cover your park and if there is a trip charge for your area.

What should I ask a pro before they start?

Ask if they use RV-safe (non-toxic) antifreeze, whether they bypass the water heater so you do not waste antifreeze, and whether they drain the low point lines and traps. Also ask if they check the water heater, holding tanks, and any ice maker or washer you have.

How long does winterizing take?

A basic winterize or de-winterize usually takes about one to two hours, depending on the size of the rig and how much plumbing it has. A full seasonal check that also covers the roof, seals, tires, and batteries takes longer.

What happens if my pipes already froze and cracked?

A tech can pressure test the system to find the cracks, then replace the damaged pipes, fittings, pump, or water heater. Catching it early keeps the repair smaller. If you had a freeze, it is worth a full check because more than one spot can be damaged.

Do I need to be there for the service?

Often you do not, as long as the tech has access to the rig and knows where the keys and hookups are. Many owners have it done while they are away or before they arrive for the season. Confirm access and payment details ahead of time.

Can the same visit include a general seasonal check?

Yes. Many owners bundle winterizing with a seasonal look over the roof and seals, tire pressure and age, battery condition, and slide-out lubrication. It is a good time to catch small issues before they turn into leaks or breakdowns.
