As someone with a long, proven, record working on the repair and restoration of historic masonry, I have been working with Stonehealth Ltd from the time that they first launched the Jos system into the UK during the 1980’s. Since then I have seen the introduction of the Doff and the Torc systems (which superseded Jos). The company’s experience and knowledge of masonry cleaning, in particular brickwork, has been most useful to myself and the many clients I have had occasion to refer them to. Whilst Stonehealth Ltd do not carry out contractual work they will arrange for supervised trials, produce reports, and assist architects and other specifiers with preparing masonry cleaning specifications. I have no hesitation in recommending this reliable professional organisation who have high standards and an impeccable reputation.
THE DOFF SYSTEM EFFECTIVELY REMOVES:
Paint Coatings | Certain Types of Graffiti | Bird or Vermin Fouling | Algae, Moss, Fungi | Other Biological Matter
