This experience enables us to choose the most effective and gentle method needed to complete any given project cost effectively, with no damage to the substrate.

Therma Tech System
For the gentle removal of Flexible Paints, Graffiti, Algae, Moss and more
The ThermaTech System is unique in achieving temperatures up to 150 degrees at the nozzle end - making it a 'superheated water system'. Designed and developed to effectively remove paint, biological matter and general dirt and grime without causing harm or shock to the substrate.
What can ThermaTech be used for?
The steam/superheated water will remove paint, moss, algae, fungi and other biological matter and will also kill off spores. This means there's then no need to use a chemical biocide during the removal process or as a protection against further biological activity.
How does it work?
ThermaTech cleans stonework and masonry using high-temperature steam. Whilst the temperature in the system is high, the pressure on the surface being cleaned is very gentle and the volume of water is low. The surface is therefore not saturated and will be dry within minutes.
With absolutly 0% surface damage.
We recommend the ThermaTech for use on surfaces such as brick, stone, concrete, tiled (glazed and encaustic), wood, faience and terracotta. It is a useful sterilisation tool for kitchens, toilets, swimming pools, hospitals and factories.
History highlights include the 13th century Mappa Mundi, the oldest surviving map of the world and a fascinating social document of the time. The Cathedral dominates its area with intricate stonework dating back to the 11th century. The Victorian art gallery and museum is another fascinating piece of architecture, with exhibits to match and the smaller, but very interesting Black and White House Museum gives a snapshot of city life going back to Jacobean time.
All around the town centre, there are examples of fine and fascinating buildings and areas like the Butter Market that is now surrounded by modern shops and offices, but stands proudly for the City's history.
With historic buildings in and around the town, some national monuments, some still in use, owned privately or by the local council, we often find ourselves called on in the Hereford area to ensure that when the grime from traffic, bird fouling, general day to day soiling or even graffiti is removed from a treasured building, there is no damage to the often delicate stonework beneath.
From removal of old paint for a domestic redecoration project, or the intricate cleaning of stone work in a cathedral using the poultice method, you will find that wherever you are in Hereford or Herefordshire, you will get a quick response, highly competitive quotation and thorough cleaning from DJ Cooper.
