Surface Preparation – Nationwide
Your Trusted Cleaning and Surface Preparation Experts
Greenleaf Contractors Ltd was formed in 2000, initially as a ‘Farrow System’ franchise.
We specialise in surface preparation and cleaning services with a low pressure damp abrasive cleaning system “Sand Jetting”, but also offer traditional sand (grit) blasting aka sandblasting, pressure washing, High Pressure (500bar) and Ultra High Pressure (2500+ bar) water blasting, chemical cleaning and Superheated steam cleaning services – sometimes known as DOFF™. We also offer post blast cleaning services such as priming and painting including on-site Galvanising, and products such as Moisture Curing Urethanes, and stone and brick sealing using Silane and Anti Graffiti products.
If you are looking for a local or nationwide contractor specialising in surface preparation including blast and sand blasting services, pressure washing, chemical stripping and steam cleaning we can help. We cover a wide geographic area with daily access to the whole of Yorkshire, Lincolnshire, Nottinghamshire and Derbyshire, regularly working in northern cities and towns such as Leeds, Bradford, Newcastle, Sheffield, Hull, York & Lincoln.
But the nature of the Industry means that it is entirely normal for us to need to travel to do work, and in recent years we have also travelled as far as Edinburgh, Anglesey, Newbury, Southampton, Somerset, London and Kent. We spent quite a lot time during Covid commuting to Bolton (all the hotels being closed)!
Surface Preparation and Cleaning
Specialising in techniques such as sandblasting, high-pressure water jetting, chemical cleaning, and superheated steam cleaning, Greenleaf Contractors offers comprehensive solutions for preparing and maintaining various surfaces.
Post-Blast Finishing
Providing services like priming, painting, on-site galvanising, and protective coatings to ensure surfaces are well-finished and protected against environmental factors.
Specialist Equipment Services and Training
Offering machine sourcing, parts, maintenance, and tailored training courses for specialised cleaning equipment, alongside equipment hire to support ongoing operations.
Expertise in Surface Preparation and Specialist Equipment Solutions
As members of the Ashrose Group nationwide coverage can be arranged. In 2002, along with three other ex-franchisees, we split with the ‘Farrow System’ and formed the Ashrose Group, a co-operative of companies offering similar low pressure sand jet cleaning services across the United Kingdom.
Since the placing of Farrow System Ltd in Administration on 22nd January 2008 we have been contacted by a number of users and suppliers looking for a source and outlet for Machines & Parts. We can find parts, second hand machines, and can price similar machines as well. We also provide advice and training in the art of setting up and using these machines. We can run specialist training courses in Farrow System machines, either at our premises, at yours, or even on site – this can be tailored to suit the applications you have for your machine. It is even possible to hire a replacement machine from us to keep you going while your machine is under the doctor!
While we specialise in damp sand blasting, which we tend to describe as ‘sand jetting’ and other sand or grit blasting applications there are applications where other techniques might be more suitable, not only will we admit this (!) but where possible we will try to find you an alternative and solve your challenge.
Expanding and Innovating: Advanced Cleaning and Protective Solutions
In recent years we have started to provide Dry Ice Blasting services, but then have moved onto High Pressure (to 500bar) Water Jet Cleaning, and from that onto Ultra High Pressure (2500bar) Water jet cleaning – typically using this to remove playground markings – which makes up a significant amount of our work – particularly during the school holidays; Even more recently with regular specifications of DOFF system cleaning within Listed Building Specifications we too have started to offer medium pressure superheated steam jetting to match this requirement.
In 2002 we started to use Zinga as a suitable primer for slurry blasted steel, this product provides a similar (or improved) protection as Hot Dip Galvanising effectively allowing On Site Galvanising. In early 2004 Greenleaf Contractors was approved as a Zinga UK Applicator.
A few years later and we discovered the delights of Moisture Curing Urethane primers and paints – just what we had been looking for as a complement to Zinga and to damp, slurry blasted steel. Trident Coatings are our supplier of choice. These paints are particularly suited to Blasting and painting in the United Kingdom – coping with foggy days where the humidity is high, bright sunny days, and indeed the depths of winter – we first used Moisture Curing Urethanes for a set of farm buildings with snow all around.
More recently we’ve done a lot more superheated steam cleaning of surfaces, which is very heavily promoted by Conservation Officers who like to specify Stonehealth’s DOFF (TM) system, although we use a machine made by Thermatech. And lately we have started to have enquiries for the removal of spray foam insulation from customer’s lofts when they find they can’t get a mortgage (or their buyer’s can’t get a mortgage) with the stuff in place.
Since the formation of the Ashrose Group, there has been some diversification, and additional services are now offered by Greenleaf Contractors and more details can be found within this, our Company Specific, website.
