DIY Motorhome & Caravan Repairs with Cost Breakdowns

Tackling these repairs yourself not only cuts costs but also gives you confidence on the road, knowing you can handle minor problems without calling in a professional.

Below, we’ll walk through some of the most common caravan DIY repairs, complete with step-by-step instructions and cost breakdowns.

Changing a Flat Tyre

Nothing puts a stop to a trip quite like a flat tyre, but the good news is that changing one is a straightforward job. If you’ve ever changed a car tyre, the process is much the same. Even if you haven’t, this is one of the most useful DIY skills any caravan owner can learn. Here’s how to do it.

What You’ll Need

  • Spare tyre ($150–$300)
  • Wheel brace ($30–$50)
  • Caravan jack ($50–$150)
  • Chocks ($20–$40)

Steps to Change a Flat Tyre

  1. Park safely: Pull over on level ground, apply the handbrake, and chock the opposite wheel from the one you’re going to change.
  2. Loosen the wheel nuts: Use a wheel brace to loosen (but not remove) the nuts on the flat tyre.
  3. Jack up the caravan: Position the jack under the recommended jacking point and lift the caravan until the tyre is off the ground.
  4. Remove the wheel nuts and tyre: Take off the nuts completely and remove the flat tyre.
  5. Fit the spare: Align the spare tyre with the wheel hub and secure it with the nuts.
  6. Lower the caravan: Slowly bring the caravan back down and fully tighten the wheel nuts.
  7. Check the tyre pressure: Make sure the spare is inflated to the correct PSI before hitting the road.

DIY Cost Estimate: $250–$540 for the initial cost of the tools and spare tyre.

Workshop Cost: $50–$100 in labour per tyre change, plus the cost of the tyre itself.

Caravan electrical systems aren’t complicated, but when something stops working, a blown fuse is often the cause. If a light, fridge, or power outlet suddenly goes dead, checking and replacing the fuse is an easy fix. Here’s what you need to do.

  • Replacement fuses ($5–$15 for a pack)
  • Fuse puller or needle-nose pliers ($10–$20)

Steps to Replace a Blown Fuse:

  1. Turn off power: To be safe, disconnect the caravan from mains power.
  2. Locate the fuse box: Usually found in a cupboard or under the bed.

  4. Remove the old fuse: Use a fuse puller or pliers to pull it out.
  5. Insert the new fuse: Match the correct amp rating and push it into place.

DIY Cost Estimate: $15–$35

Most small leaks can be sealed up with basic tools in under an hour.

What You’ll Need

  • Silicone sealant ($10–$30)
  • Adjustable spanner ($20–$40)
  • Teflon tape ($5–$10)

Steps to Fix a Leak:

  1. Identify the leak: Check under the sink, around taps, or at pipe connections to find where the leak is coming from/
  2. Turn off the water supply: Turn off the water supply to prevent any mess while you’re working.
  3. Tighten fittings: Use an adjustable spanner to secure loose connections.
  4. Apply Teflon tape: Wrap around thread connections to create a better seal.

  6. Test for leaks: Turn the water back on and check for any remaining drips.
