Cleaning render and stone on exterior of buildings using DOFF

Solution

An exclusion or warning zone will be set up around the area of work using cones; tape and warning signs will be posted in any area where a hosepipe crosses a walkway, to warn of a potential trip hazard.
Assess the situation prior to commencing work. Ensure that there is no danger to the public – cordon off areas if required.
Ensure that the poles will not come into contact with any electric cables or overhead power lines.
Ensure that any falling residue water does not create a danger of slipping. You must use De – Ionised water when using water fed poles.
Poles are extended at ground level sufficient to reach the high level windows or building fabric.
Poles over 15 metres overall length require x2 operatives to extend the pole to the correct height to avoid manual handling issues.

Only Stonehealth approved operator to use the Doff equipment.
All areas that are cleaned using the DOFF will involve a small amount of water pooling nearby.
Safety signs and barrier tape MUST be used to safely cordon off your work areas.
Steam cleaning at extremely low pressure – 50 BAR MAX with water flow of only up to 5 litres per minute will completely remove all organic matter and atmospheric pollution, from the surface of the area cleaned. We will also apply under controlled conditions a SoftWash solution to help prevent re growth occurring (this product is comparable to a biocide, and in our opinion works much better)

What our Clients Think


See all testimonials
  • As always, Purple Rhino have carried out the ultimate K-Rend, render cleaning to this extremely large apartment block in Margate. The through coloured render was extremely dirty but now thanks to the render cleaning team at Purple Rhino the buildings K Render looks like new.

    We have worked with Purple Rhino K-Rend Render Cleaning specialists for more than 5 years and are always delighted with the service and excellent results from the whole team.

  • “Purple Rhino first sent us through an informative booklet about Industrial building cleaning in March 2013, I invited them down to survey our six storey building in Crawley, West Sussex known as The Atrium, they agreed to carry out a test sample FREE of charge and without obligation. The test results were extremely positive and it was agreed that the whole building façade and glass restoration service was needed to make the building look presentable once again. The works took them just over three weeks, and they gained access by using the building’s own cradle system and the use of Access Platforms, with minimal disruption to our staff and neighbours, the building now looks extremely good as it did when constructed. We will be using Purple Rhino for an agreed scheduled cleaning service to keep the building looking pristine at all times”
