Undersealing & Welding in Plymouth, Devon

Underseal Rust Proofing in Plymouth

I've been undersealing in Plymouth for over 17 years.


Although nothing can completely prevent rust, I can underseal your car at my Plymouth garage, to slow down rust corrosion.

Waxoyl underseal helps to preserve the condition of your vehicle.

It can be re-applied as often as needed,, which is generally every 3-5 years, depending on use and weather conditions.


I clean the underside of your vehicle, using high pressure sprays, to remove dirt and loose rust. It then allowed to dry. 

I wire brush where necessary to further remove flaking rust.


Rust prevention treatment is applied under pressure.

This can be injected under high pressure, into body panels. The mist spray and high pressure allows it to reach many inaccessible areas.


Not everybody wants, or can afford, a high-cost treatment.

So my treatment options are tailored to suit your needs.


My price starts from £125+vat for underside only.


Vehicles are best left with me for one full working day, and then overnight, to allow the waxoyl treatment to harden, and the smell to disperse.

If this is not possible, you can collect your vehicle as late as possible, on the same day.


Do not powerwash, hot wash or jet-wash waxoyl after it's been applied. 


Due to safety requirements, customers cannot stay in the workshop while the vehicle is undersealed. I have a waiting room and you are welcome to arrange to see it on the ramp afterwards, whenever possible.

Welding Repairs in Plymouth

We carry out welding repairs to cars and vans at our Plymouth garage.

If the underbody of a car or van is rusted and corroded, it can weaken the structure of the vehicle. It may fail an MOT.

We assess the welding repairs needed and advise you on this.

We use the appropriate gauge steel sheet, custom or pre-fabricated repair parts to weld high quality repairs. 


We can then underseal to prolong the life of your vehicle.
