Chemical-Free Cleaning for the Surfaces That Cannot Be Replaced.

Historic buildings and listed structures require the most careful approach to cleaning. Harsh chemicals or high-pressure water can strip, erode, and permanently damage surfaces that have stood for centuries. DOFF superheated steam cleaning offers a powerful yet entirely chemical-free solution removing paint, biological matter, staining, and contamination from the most delicate masonry and stonework without causing harm to the surface beneath.

It is the method of choice for conservation projects, listed buildings, and any exterior surface that cannot tolerate conventional cleaning techniques. Our trained operatives work to the highest standards of care, making this service ideal for heritage buildings, churches, commercial facades, and architectural stonework.

What our clients say

FAQ's

Find answers to common questions about our DOFF cleaning services

What makes DOFF different from pressure washing?

DOFF uses superheated steam at lower volumes of water than pressure washing. The high temperature does the work rather than the pressure -- making it far safer for delicate surfaces while remaining highly effective at removing contamination.

Is DOFF approved for use on listed buildings?

Yes. DOFF cleaning is widely accepted and recommended for use on listed buildings and heritage structures where chemical or high-pressure cleaning is not permitted.

Will DOFF remove all types of staining?

DOFF is effective against a wide range of staining including paint, biological growth, algae, soot, and general surface contamination. Some deep staining may require additional treatment -- we will always advise honestly before starting.
