What's Included in an RV Spring Start-Up Service in Ontario

A proper spring start-up covers the plumbing system, battery and electrical, propane appliances, tires and brakes, exterior body condition, and a full roof and seal inspection. In Ontario, this matters more than it does in milder climates, because your RV just spent several months dealing with freezing temperatures, and sometimes real snow load, while sitting completely still.

Here's what a thorough spring service actually involves, system by system, and why skipping steps in any one of them causes problems that tend to surface later in the season rather than immediately.

De-Winterizing the Plumbing

Antifreeze gets flushed from the water lines, and the system gets pressure tested for leaks before you're relying on it at a campsite. This is the step people are most tempted to rush, and it's also the one where a missed crack turns into a soaked cabinet three weeks into the season, often somewhere you won't notice right away.

A thorough de-winterization, part of our plumbing system maintenance and repairs, includes checking the water heater bypass valve position, running water through every fixture to confirm nothing is blocked or leaking, and checking the low point drains to make sure they're properly sealed after being open all winter.

Battery and Electrical Check

Batteries lose charge over winter storage, sometimes more than owners expect, especially if there wasn't a maintainer connected. A technician tests capacity, checks terminal connections for corrosion (more common after a winter near roads that get heavily salted), and confirms the charging system is functioning properly before you're depending on it away from shore power.

This step also covers checking the converter and inverter if your RV has one, since these components can develop faults during long periods of disuse that aren't obvious until you're actually trying to run appliances off battery power.

Propane System and Appliance Testing

Furnace, water heater, stove, and fridge all get tested on propane during a proper spring service. Ontario winters are long enough that appliances sitting unused for four or five months sometimes need more than a quick restart to run properly again.

This includes checking for consistent ignition, confirming the furnace cycles correctly and produces steady heat as part of our HVAC system services, and testing that the fridge actually reaches and holds a safe temperature rather than just running without cooling effectively. A fridge that runs but doesn't cool is a common enough spring issue that it's worth specifically confirming rather than assuming it's fine because the compressor sounds normal.

Tire and Brake Inspection

Tires lose pressure and can develop flat spots from sitting in one position for months. Our tire and brake services check covers pressure, looking for cracking or dry rot on the sidewalls (which shows up more in units that sat outside through the winter), and confirming there's no uneven wear that developed before storage.

Brakes get checked for corrosion buildup on the rotors and calipers, which is more common in Ontario than in drier climates due to road salt exposure carried into wheel wells over the winter driving season before storage. A brake system that wasn't used for months can also develop surface rust on the rotors, which usually clears up after the first few stops but is worth a visual check regardless.

Roof and Seal Inspection

This is the step that prevents the most expensive repairs down the line, and it's also the one that's easiest to skip because it's not visible from ground level. Winter is hard on roof seals. Freeze-thaw cycles crack caulking and sealant that looked fine in the fall, and a small gap you can't see without actually getting on the roof can let water in all summer without anyone noticing until there's visible interior damage.

A thorough inspection covers all roof penetrations (vents, air conditioner mounts, antenna bases), the edge seals around the entire roofline, and the condition of the roof membrane itself for any cracking or soft spots that indicate water has already gotten underneath.

Exterior Body and Undercarriage Check

Beyond the roof, a full spring service should include a look at the exterior siding, door and window seals, and the undercarriage for any damage or corrosion that developed over winter storage. Road salt exposure from the drive to and from the storage facility, combined with months of moisture, can accelerate corrosion on metal components underneath the unit in ways that aren't obvious just walking around the outside.

Slide-Out and Awning Function Check

Slides that haven't moved in months sometimes need lubrication or a minor adjustment before they'll operate smoothly again. This is normal and usually a quick fix if caught during a proper inspection rather than discovered mid-trip when you're trying to set up at a campsite.

Awnings get the same treatment, checking that the mechanism extends and retracts evenly, the fabric hasn't developed mildew or damage from any moisture that got in during storage, and the arms move freely without catching.

Safety Equipment Check

A spring service should also include testing smoke detectors, carbon monoxide detectors, and propane leak detectors, along with confirming the fire extinguisher is charged and within its service date. These get overlooked constantly because they're not systems you actively use, but they're exactly the kind of thing you want confirmed working before you're relying on them away from home.

Fluid Levels and Engine Check (Motorized Units)

For Class A and Class C motorhomes, spring service also covers checking engine oil, coolant, transmission fluid, and washer fluid levels, along with a general look at belts and hoses for any cracking that developed over winter storage. This is in addition to, not instead of, the seasonal oil change if your unit is due for one based on mileage or time since the last change.

Basic Package vs. Full Spring Service

Some shops offer a stripped-down "de-winterization only" package that covers just the plumbing flush and pressure test, leaving everything else for the owner to check themselves or address separately. A full spring service covers all the systems above in a single visit.

The basic package costs less upfront but shifts the risk of missing something back onto you. Given how much can go wrong after a Canadian winter sitting in storage, most owners find the full service worth the difference in price, particularly for anything involving the roof and propane systems, which are harder to inspect properly without the right tools and access.

Why This Matters More in Ontario Specifically

Compare this to an RV stored in a warm climate year-round. That unit isn't dealing with freeze cycles, isn't exposed to the same road salt, and generally needs a much lighter spring check, sometimes little more than a general once-over. Ontario RVs go through considerably more over a winter (see our RV winter storage tips for the other half of this process), so the start-up service needs to actually cover more ground, not less, which is part of why generic American spring checklists tend to undersell what's actually needed here.

Many owners pair their spring start-up with a full pre-trip inspection before their first outing of the season, especially after a long winter in storage.

Our FAQ page covers a few other common questions worth a quick read too.

Keeping Records for Warranty and Resale

Beyond the immediate benefit of a properly serviced RV, keeping documentation of your spring service matters for two reasons worth mentioning. If a component fails later in the season and you need to make a warranty claim, having a record showing the RV was properly inspected in spring supports your case that the issue wasn't caused by neglect. And if you ever sell the unit, a documented service history, especially consistent spring start-ups, is exactly the kind of paper trail a buyer wants to see before trusting a used motorhome or trailer.

What You Can Check Yourself Before Drop-Off

A few things are worth doing before your appointment, both to save time and to give the technician useful information:

• Note any issues you noticed before storing the RV last fall, even small ones
• Check that you know where the water heater bypass valve is, since some shops will ask
• Take a quick look at tire condition so you can flag anything unusual right away
• Mention if the RV sat outside versus in a heated or unheated indoor space, since this affects what the technician expects to find

FAQ

How long does a spring start-up service take?

Most units take a few hours for a standard inspection and de-winterization. If something needs repair, a cracked line or a failed seal, for example, it may take longer depending on parts availability.

Can I do my own spring start-up?

Some of it, sure, especially the basics like checking fluid levels or tire pressure. Pressure testing plumbing properly, inspecting the roof from a safe vantage point, and checking propane appliances are worth having a technician handle, both for safety and to catch what's easy to miss from ground level.

When should I book my spring service?

As early as you can, ideally before the seasonal rush. Request your spring service appointment here.

Do I need a full spring service if I only used my RV a couple of times last year?

Yes. Low usage doesn't reduce the impact of winter storage on seals, batteries, and plumbing. The systems age based on time and exposure, not just how often the RV was driven.

What's the most commonly missed item in a basic spring check?

Roof and seal inspection, mainly because it requires actually getting on the roof rather than just checking systems from inside or underneath the unit.

Is a battery replacement usually needed every spring?

Not every year, but it's common enough that most shops check capacity as a matter of course. A battery that's a few years old and wasn't maintained over winter is a frequent spring replacement.

Does a full spring service include a road test?

For motorized units, yes, typically a short test drive to confirm brakes, steering, and engine performance feel correct before you're relying on it for a longer trip.

What if my RV was stored outside all winter versus in an indoor facility?

Units stored outside generally need a more thorough check, particularly for roof and seal condition, since they've been exposed to snow load, ice, and temperature swings more directly than an indoor-stored unit.

Should I winterize again if I get an unexpected cold snap after de-winterizing?

If a hard freeze is forecast after you've already de-winterized, it's worth taking precautions like running a bit of heat inside the unit or protecting exposed plumbing, rather than assuming the risk has passed for the season.

How soon before my first trip should I schedule spring service?

At least a few weeks ahead if possible, so there's time to order parts if something unexpected turns up during the inspection, rather than discovering an issue the day before you're planning to leave.
