If damage is done, it’s irreversible. If you remove the
surface of stone or break then you can’t get it back. If
there are any doubts over the credibility of machinery
and operatives, then contact us.”
Mr Crowe, who founded Gloucestershire-based Stonehealth
in 1989, said education was key to ensuring that buildings
continued to be properly treated.
“
Our intention is to make architects, surveyors and other
specifiers – including conservation officers – aware
of people working with something different to what’s
been specified or approved. Any queries on whether
the contractors and machines are genuine should be
directed to us. We know where our machines are and the
personnel who are trained to use them.
With specialist knowledge of the industry, our products have
been proven to effectively clean masonry without damage.
“
“
We place great emphasis on training the contractors who
use our equipment, as well as ensuring that our machines
are properly specified.
The Stonehealth DOFF and TORC systems have been used on
some of Britain’s most iconic landmarks, such as Westminster
Abbey, Tower of London and Canterbury Cathedral.
Our reputation has been earned over decades of
innovation and care for our industry and we won’t
tolerate abuse of it, or the risk of unsatisfactory results from
impostors harming the likelihood of our products being
specified again.”
DOFF is a steam based stone
cleaning system. It is unlike any
other steam system and can
achieve temperatures of 150°C
at the nozzle end. The operator is
able to vary the temperature and
pressure to remove many types
of paint or biological matter.
To help ensure that only bona fide contractors are considered
and awarded contracts, Stonehealth has set up its Approved
Rosette Contractors Scheme.
Approved contractors must meet stringent criteria including:
full training in use of Stonehealth equipment, reviewed every
year; use of only genuine Stonehealth parts and materials;
annual inspection and servicing of machinery by Stonehealth;
provision of at least two customer testimonials per year to
maintain Rosette status.
