Redish Motorsport. Bristol. Anyone used them recently?
Discussion
Considering an underbody inspection of my E39 M5 with Redish.
Anyone out there with recent experience of them for this type of work?
I know there's a fixed price for the inspection but what is their general pricing for work beyond that ie. the actual cutting out of corrosion, welding in new metal and making good?
Any idea of their hourly rate for this rust remediation work?

Can't comment on that particular sort of work but they took my F10 M5 in September, gave it a preventative rod bearing change as well as remediating a number of general service / wear and tear items and I have to say they were absolutely meticulous in everything they did. They are approx 100 miles away from me but I won't take the car anywhere else in the future.
They've been very responsive to my initial inquiry with voice messages from James at Redish (via WhatsApp) outlining what's involved in the inspection. Seemed very knowledgeable and enthusiastic. All good so far.
I know rust remediation work is individual to each car but does anyone have experience of their pricing for this sort of work?
So that I can get a feel for costs, would be good to get some pricing feedback from someone who, say, at the 'deep end', has had both sills, jacking points replaced and a general underbody de-scale carried.
Also at the other end of the spectrum, perhaps some indication from a customer who had less invasive cutting out/replacing of just the ends of the sill and nothing more.
I have to say, the YouTube videos are somewhat terrifying. Here's the latest (there are others!):-
Pretty sure mine is nowhere near as bad but can't be certain until the plastic sill covers and wheel arch liners are removed.

My E39 530i Sport is going down on the 23rd for it's inspection and quote for the rear jacking points to be repaired, when I spoke to James about estimated costs he said that the red M5 on YouTube was in the £5-8K mark for the owner to get the work done.
Easier to swallow if your doing the work on an M5, not so much on a non-M car.

Many thanks. That's a very useful benchmark.Easier to swallow if your doing the work on an M5, not so much on a non-M car.

Agree with everything thats been said to date except this one, sorry.
Covered good friends car in underseal and scratches, the reply when raised was "these things happen"
Weld tech or Redish?Covered good friends car in underseal and scratches, the reply when raised was "these things happen"
Their attention to detail, and commitment to quality is exceptional.

For my E39 M5 in 2018 I used a friend of a friend who is a professional restorer in Kent. I had sills, jacking points and rear arches done with new metal and painted for less than £1k. PM me if you'd like the contact.
Thanks for this. I need same work on 2002 e39 M5. Is your friend still doing this sill rebuild work and if so how do I contact them. Please many thanks Since this thread popped up again it might be useful to others to relay my eventual experience of getting the sills and jacking points issues resolved.
The rot hadn't extended as far as feared in my case but metal close to all 4 jacking points was all removed and new stuff let in. Some sections of the lower sills were also replaced. Those long plastic covers hid a surprising amount of corroded metal which was all removed.
I supplied the welder with some galvanised repair panels which were canabalised and made the job easier and gave a more OE look to the repairs. The panels were of thicker gauge galvanised metal (1mm thick instead of 0.8mm) and came from these people in Denmark: https://shop.klokkerholm.com/da/0065012
The fuel tank had to come out too for safety reasons but also because it's really difficult to effect a proper repair to metal very close to the tank. (See photo below). I've seen a couple of examples of work done in this area on other cars with the tank in situ, and rust compromised metal was either left in place or crudely plated over. The finished welds were also really untidy there too no doubt due to access being limited by the presence of the tank.
(Above) The fuel tank normally sits hard up against where the ragged edge of corrosion is, close to the exposed jacking point in the pic. All of that rotten metal was cut out and replaced. I find it hard to believe this sort of work can be done properly, and safely, with the tank in place.
(Above) Quite tidy work.
(Above) New metal on the nearside front. The nearside rear sill area also required work.
Total cost for welding work on both sills/rocker areas (in the summer of 2025) was £4k.

First class company, helpful, knowledgeable and would have no problem recommending them. They did rod bearings, vanos rebuild and major service two years ago on a z4mr and I was so impressed that I went back last week for a couple of other bits and a minor service.
I live in Belfast, so not just around the corner for me, but well worth it.
Thanks James and Simon.
