Mobile RV winterizing.
Before the first freeze.

Book before the first hard overnight freeze. Across Southern Ontario that usually means mid-October to early November, but a single -4 °C night is enough to split a water line, so if a cold snap is in the forecast and the RV still has water in it, winterize now rather than waiting for a date on the calendar.

It depends on the unit — a single-axle travel trailer with one water heater is quick, while a fifth wheel with a washer hookup, outdoor kitchen and ice maker takes longer and needs more antifreeze. You get a written quote before we start, and because we come to you there is no towing cost and no storage-yard drop-off.

Yes — that's the whole point of a mobile service. We work at your home, your seasonal site, your campground or your storage lot anywhere in our Southern Ontario service area. The RV does not have to move and you do not have to be there the whole time, as long as we can get access to it.

Compressed air pushes most of the water out of the lines, but low spots, traps and valve bodies can still hold enough water to crack a fitting. Non-toxic RV antifreeze fills what air can't clear and protects P-traps and the toilet valve. We do both: blow out first, then circulate antifreeze through every fixture until it runs pink.

Fresh, grey and black tanks drained and flushed, low-point drains opened, water heater drained and bypassed (and the anode inspected), lines blown out with regulated air, non-toxic RV antifreeze pumped through every hot and cold fixture including the outdoor shower and toilet, P-traps protected, water filters removed, pump winterized, and a walkaround of seals, vents and the battery before we leave.

You need to keep it charged, not necessarily remove it. A lead-acid battery left to self-discharge in the cold can freeze and be destroyed. We disconnect the parasitic draws, check the state of charge and either set it up on a maintainer or pull it for indoor storage. Lithium batteries have different rules — they must not be charged below freezing — and we'll set yours up accordingly.

Not with the plumbing in use — once the system is full of antifreeze the RV is stored, not camped in. If you want to camp through the winter, tell us and we'll look at heated hose, tank heaters, skirting and underbelly insulation instead so you can run water safely in the cold.

Water expands as it freezes and splits whatever contains it — PEX lines, fittings, the water pump head, the water heater tank, the toilet valve. The damage rarely shows until spring, when you pressurize the system and water sprays inside the walls and floor. Repairs routinely cost many times what winterizing does, and the water damage that follows can cost more again.

Once overnight lows stay reliably above freezing — usually April in Southern Ontario. De-winterizing means flushing all the antifreeze out, re-installing the water heater bypass and filters, sanitizing the fresh water system with a bleach solution and rinsing it, then pressurizing and leak-testing every fixture. We book de-winterizing visits in the spring and can pair it with a pre-season safety check.

Yes, and it's the best time to do it. A seam that only weeps in summer rain becomes a freeze-thaw problem all winter under snow load. We walk the roof, check sealant around vents, skylights, the AC gasket and the front and rear caps, and flag anything that should be resealed before the snow comes.

Most travel trailers and fifth wheels take about an hour to an hour and a half. Motorhomes and units with washers, ice makers, outdoor kitchens or dual water heaters take longer. We'll tell you the expected window when you book.

Yes — travel trailers, fifth wheels, truck campers, Class A, B and C motorhomes and toy haulers. Motorhomes have extra items such as the chassis, generator and sometimes a second water heater, and those are included in the walkthrough.
