Specialist DOFF & Steam Cleaning for Historic & Listed Buildings

Why Choose DOFF Cleaning?

Preserving the beauty and integrity of historic, listed, and period buildings requires specialist care. Our DOFF steam cleaning service is our preferred method for stone, brickwork, and masonry, ensuring a deep clean without damage.

DOFF steam cleaning uses superheated steam

Unlike abrasive cleaning methods, DOFF steam cleaning uses superheated steam (up to 150°C) to gently lift dirt, pollutants, and biological growth from surfaces. It is particularly effective on softer masonry like brick, limestone, and sandstone, where traditional methods may cause damage.
