When Stonehealth first started selling the Jos stone cleaning system in the 1980s, the industry was awash with grit blasting, inappropriate chemicals and flooding all in the name of cleaning, yet doing irreparable damage to buildings. Even today these methods are still being used. Stonehealth has always had a different approach.
Are You A Contractor?
Over the past 30+ years, Stonehealth has made further developments, including the introduction of the TORC and DOFF Integra systems, both of which have proven to be more effective than the Jos ever was.
Stonehealth systems have such a valued reputation with Architects, Conservation Officers and other specifiers, that less reputable companies have been known to claim that they have Stonehealth systems or are a ‘Stonehealth Approved Contractor’ in order to win contracts.
To help ensure that only bonafide contractors are considered and awarded contracts, over 6 years ago, we introduced the ‘Stonehealth Rosette Scheme’. Stonehealth does not receive any royalties or commissions from contractors for referrals. When providing referrals, Stonehealth has the responsibility for listing only genuine contractors who will carry out work in a way that meets all the Stonehealth Rosette requirements.
In discussion with Architects, Conservation Officers, specifiers and contractors, the company has been encouraged to tighten up the criteria for eligibility onto this list. The idea of the rosette standard has been enthusiastically supported since its launch in order to outlaw phoney contractors.

Join the Stonehealth
There are no fees to become a Stonehealth Rosette Approved Contractor and the benefits include

We maintain an online directory of ‘Stonehealth Rosette Approved’ contractors.
The directory is searched regularly by architects, conservation officers and customers alike, all of whom are looking to appoint contractors in their local areas to carry out work. The directory is unbiased and search results are based on geographical location (closest contractor to the search area), however, we prioritise contractors in the search results that are ‘Stonehealth Rosette Approved’. Commissions are never paid and referrals are completely FREE.
Rosette Approved contractors also receive 5% OFF EVERYTHING! That includes Stonehealth machine servicing, products and parts.
Contractors are issued with an official Stonehealth Rosette Approved ID card verifying they are fully qualified to operate the machinery as well as verifying the machinery is fully serviced to meet the Stonehealth Rosette standard.
Machines are serviced regularly by a Stonehealth qualified engineer and approved by our lead technical director which certifies that the DOFF/TORC systems are safe and operating to their full potential.
