Listed and heritage buildings are often built from softer stone, lime mortars and handmade brick that react badly to aggressive cleaning. Get it wrong and the damage is permanent, and potentially a breach of listed building controls.
We start with a survey and trial patches, then build the method around the building: usually low-pressure Thermatech steam cleaning, with other techniques only where they're appropriate and agreed.
Owners of listed buildings will often need listed building consent before exterior cleaning or paint removal. We'll talk you through the method we plan to use so you can discuss it with your local conservation officer before work begins.

“Absolutely transformed our sandstone farmhouse. The render was black and we'd given up hope. Spartan brought it back to life in one day. Couldn't be happier.”
“Used them to clean the render and repoint our listed building. Professional from start to finish. The conservation officer was happy too, which says it all.”
“The driveway looks brand new. They were on time, tidy, and the price was fair. Will definitely use again for the back of the house.”

It depends on the material. Harder surfaces and metalwork suit sandblasting well, but softer and historic stone often doesn't. We test first and, where it's the better option, recommend a gentler method such as Thermatech steam cleaning.
