Find the extent of the corrosion
A small visible hole can be part of a larger weakened area. A durable repair needs sound metal around the damage, so we inspect the affected section and surrounding structure before recommending work.
Rust can extend under paint, seam sealer or protective coating. Its full extent may only become clear during preparation. Access around fuel lines, wiring and trim also affects what is practical; we discuss additional findings before proceeding.
Inspection before a welding quote
Inspection before quotation
Corrosion can extend beyond the visible hole. We inspect the surrounding material and agree the preparation, welding and finishing work before starting.
See live prices →Exhaust and MOT-related work
We can assess suitable exhaust welding and corrosion repairs identified during an MOT or inspection. The repair method depends on the location and material condition. We explain when replacement makes more sense than a patch.
Repair first, protect afterwards
Where welding is appropriate, we agree the area, preparation and finishing work. Underseal or other protection may be suitable after the repair and correct surface preparation.
We explain the treatment proposed and any neighbouring corrosion to monitor. If the wider structure is extensively corroded, we discuss whether a local repair is a sensible option for the car.
Frequently asked questions
Can you repair a hole in a sill?
We can assess it. The location and extent of corrosion determine the repair needed.
Do you apply underseal?
We can discuss suitable protection after assessing the underside and any repairs required.
Can every corroded area be welded?
No. Material condition, access and the structure involved can limit what is appropriate. We advise after inspection.
