Greenleaf Contractors Ltd, trading as Ashrose Group (Northern)

Part 1: A Farrow System Franchise.

Greenleaf Contractors Ltd was formed in 2000, initially as a 'Farrow System' franchise

A farrow Rig

Here are three of our first employee's practicing with the machine in Mr Farrow's yard down in Norfolk. We found ourselves with a 'rig' but no towing vehicle, as the 'deal' Nigel Farrow had done with the local Mitsubishi dealer had meant that our brand new L200 in company colours wasn't available for some weeks after we had paid for it!

Part 2: The Ashrose Group

The franchise organisation failed in late 2001 / early 2002. there were a couple of reasons for this, firstly the exclusive territories weren't very exclusive (as Nigel hadn't actually invented the machines, there was nothing he could do to stop our next door neighbours buying and operating one from the actual inventers and builders of the machines). Secondly the 'Farrow Formula' abrasive had actually been banned by the Health and Safety Executive for much of 2001 and Nigel hadn't told us.

Four of the ex-franchiees (those who were on speaking terms with each other) formed the Ashrose Group. (while attempting to sell the machines back to, and get our money back from, Mr Farrow!)

This is that same machine, a few months later, re-signed looking a bit older!

Part 3... Greenleaf and Surfprep

Another year or so went by, and two of the group went their separate ways, our London man Steve, sailed round the world and ended up (presumably) back in New Zealand - we haven't heard of him since. Our North East and North West man Richard bought a very large number of chickens, and started wholesale egg production. This left the remaining pair to continue, and we, as Greenleaf Contractors. set up our own website (this one) - mainly because we couldn't get anyone to contribute pictures, text or money to progress the Ashrose Website.

Our Current Specialities

We now specialise in surface preparation and cleaning services, which include blast cleaning, sand blasting, pressure washing, High Pressure (up to 500 bar) Water Jetting, Ultra High Pressure (to 3000 bar) Water Blasting (UHP), Dry Ice Blasting, chemical cleaning and steam cleaning services. We also offer post blast cleaning services such as priming and painting including on-site Galvanising using Zinga and stone and brick sealing using Silane products.

If you are looking for a contractor then we can help! We cover a wide geographic area including the whole of Yorkshire, Lincolnshire, Nottinghamshire and Derbyshire, regularly working in northern cities and towns such as Leeds, Bradford, Newcastle, Sheffield, Hull, York & Lincoln. In the past years we have also travelled as far as Essex, Edinburgh, London (lots!), Birmingham, Anglesey, Llandudno, and deepest Cornwall;

We at Greenleaf Contractors are a two man operation (although we have been a little bigger in the past) with both of us having had more than 17 years experience of doing the job.


Louis doesn't say much, but just gets on and does the work, and we both believe that we are mainly brought onto building sites to prove that however bad your job is, we do something more unpleasant for a living! Digging out cesspits is the only exception we can think of, although sometimes when hot water pressure washing pigeon poo out of inaccessible places - we can sink that low as well!


Tom (pictured above in his role as 'creature from the pit' - a lovely job in a cellar in Shropshire at Easter 2013) started his career as an Aerodynamicist at British Aerospace, initially as a Graduate Mechanical Engineer and progressing up the organisation to project manage 'one of the most expensive 100gallon fuel tanks in the world' - he thought himself underpaid and undervalued until he started out on his own with a Farrow System Franchise!

He made the mistake of watching the BBC's Tomorrow's World program in February 2000 (actually to see an article on Ejection Seats) - saw Mr Farrow spouting about 'his invention' (standing next to a machine he had bought from a company down the road from him, in green, that he had painted blue and written 'Farrow System' on the side of) - and the rest is history.

This picture is perhaps a warning to others to wear appropriate PPE when dry ice blasting soot from old hot water systems!

On the whole, both of us like the variation that the job offers and sometimes - such as with the bronze war memorials featured higher up this page it is very satisfying!

Certificates / Qualifications

Tom also has an A+ for his Blood Group, a Master's Degree in Mechanical Engineering, and even has an M.B.A. (Master of Business Administration apparently!). When he isn't repairing blast machines, bank accounts, VAT returns, vehicles and trailers, or indeed Websites (for he is the web master), oh, and pricing jobs, he is probably catching up on some well earned sleep!

We are insured for £10million Public Liability and Employer's Liability.

Our Blast Pots (unlike many in the industry!) have pressure test certificates (this is a 2meg file - so ask and we will send!)
