Stone cleaning, brick cleaning, DOFF, heritage conservation, repointing. Every project starts with a survey. We specify the method before we pick up a tool.
The right method for this building, chosen before any tool touches it.
Diagnostic-led stone cleaning for Portland stone, Bath stone, limestone, and sandstone facades. The right method depends on the building, not the budget.
Learn more →Superheated low-pressure steam at 150°C. The specified method for listed buildings, conservation areas, and ornate carved stonework.
Learn more →London stock brick is softer than modern brick. Acid will strip it. We clean Victorian and Georgian brickwork with methods specified for the material.
Learn more →Swirling vortex of fine aggregate for heavily carbonated or painted stone. Powerful but precise — specified when DOFF alone won't shift the soiling.
Learn more → 05Poultice and hand cleaning — no steam, no aggregate. The right choice for localised staining and the most fragile surfaces.
Learn more → 06A fine intermittent mist applied over hours, not minutes. The gentlest method we offer, for the most fragile historic stone.
Learn more →The material is read before any method is chosen.
Working on a listed building requires an agreed method, conservation officer liaison, and full written records on completion. We handle all of it.
Learn more →London's defining facade material. Characterful in soiled patina, exceptional when correctly cleaned. A stone that rewards careful method selection.
Learn more →End-to-end facade restoration combining cleaning, repair, repointing, and consolidation. For buildings where one trade isn't enough.
Learn more →Minimum intervention, correctly specified — for mortar, paint, and graffiti alike.
Wrong mortar causes more damage than the original soiling. Hard cement on soft brick, incorrect joint profiles, colour mismatches — we see the consequences daily.
Learn more → 11Masonry paint, limewash, and protective coatings removed without damage to the substrate. Chemical or steam, specified by coating type and stone.
Learn more →Fresh spray paint needs a fast response, not a rushed one. Method matched to the paint and the substrate.
