Portland Stone Cleaning – Slough

Project Details

Lady Elizabeth House is a Nursing Home located in Slough.The Portland Stone was covered in a green hue.


Bell Group Ltd



The building was in need of cleaning and restoring to its former glory – without causing any damage to the Portland Stone.


Portland Stone is quite soft and therefore the only way to clean safely is by using super heated steam

Using a DOFF system was the answer as the Doff system super heats the water to 150 degrees C

By steam cleaning the facade we acheived astonishing results

By carefully using this proven method (English Heritage ONLY approve DOFF made by Stonehealth) the Portland Stone was revealed as new once again.

What our Clients Think

See all testimonials
  • From my initial contact with Purple Rhino to the finish, their work was very professionally carried out. Their team arrived on the arranged date and completed the work to a very high standard. Also, at very short notice, they managed to carry out a large cleaning schedule over a weekend in order for the school to look it’s best for a visit by RIBA judges. This was safely completed while various areas were in use. Definitely a five star service and I would recommend this company.
