Volkswagen Crafter sill repair welding when this Volkswagen Crafter arrived at our workshop, it was clear the sill had suffered significant damage. Years of wear, exposure to the elements, and underlying corrosion had weakened a critical structural area of the vehicle. Left untreated, this type of damage can compromise both safety and longevity.
At Kinmel Campers, we specialise in restoring vans to a factory-standard finish, ensuring not only visual improvement but also structural integrity that lasts.
Assessing the Damage
The first stage in any repair like this is a full inspection. In this case, the sill showed:
- Severe rust penetration
- Distorted and weakened metal
- Previous wear compromising structure
- Internal corrosion spreading along seams
This isn’t just cosmetic damage — the sill is a load-bearing structural component. If left untreated, it can lead to further deterioration across the chassis.
Preparing the Area
Before any welding work could begin, the damaged section needed to be properly prepared.
We started by:
- Removing all rusted and weakened metal
- Grinding back to clean, solid material
- Exposing the full extent of the corrosion
- Cleaning surrounding areas to prevent contamination
This stage is critical. Cutting corners here results in poor weld quality and future failure — something we never compromise on.
Rebuilding the Structure
Once the damaged metal was removed, the next step was to rebuild the sill using a precision prefab repair section.
To ensure a perfect fit:
- The surrounding metal was reshaped back to its original profile
- Alignment was carefully adjusted
- The repair panel was test-fitted multiple times
This ensures the repair integrates seamlessly — not just visually, but structurally.
Welding the Sill
With everything aligned, we moved on to welding.
Our approach focuses on:
- Strong, consistent weld penetration
- Maintaining original structural strength
- Avoiding heat distortion
- Creating a clean, durable finish
Each weld is carefully placed to replicate factory strength while ensuring long-term durability.
This isn’t quick patchwork — it’s proper structural restoration.
Finishing & Protection
Once the welding was complete, the sill was:
- Fully dressed and smoothed
- Checked for strength and consistency
- Prepared for protection
Although the customer requested a more minimal finish, we never send out exposed bare metal.
To protect the repair, we applied:
- Anti-corrosion treatment
- Protective coating
- Sealing to prevent moisture ingress
This ensures the repair lasts and prevents the same issue from returning.
Why Proper Sill Repair Matters
A lot of van repairs on the market focus purely on appearance. The problem is — cosmetic fixes don’t solve structural issues.
A properly repaired sill:
- Restores structural integrity
- Improves safety
- Prevents further corrosion spread
- Maintains vehicle value
Done incorrectly, it can lead to:
- MOT failures
- Increased repair costs later
- Structural weakness
That’s why we always approach these jobs with a long-term mindset.
The Result
The finished repair brought this Volkswagen Crafter sill back to life:
✔ Structurally sound
✔ Clean, professional finish
✔ Protected against future corrosion
✔ Built to last
Most importantly, the repair blends seamlessly into the vehicle — exactly how it should be.
Looking After Your Van
If you’re starting to notice:
- Bubbling paint
- Rust along the sill
- Soft or weakened metal
It’s best to act early.
Catching these issues sooner:
- Reduces repair costs
- Prevents structural damage
- Keeps your van on the road longer
