London stone & brick specialists
Specialist cleaning, paint removal and restoration for period and contemporary buildings. Careful methods. No shortcuts. Results that age gracefully.
Nothing is quoted blind.
“The goal is always the same: to bring a building back to itself, without erasing what makes it old.”
Before any method is chosen, the material is read — its age, its weathering, its prior treatments, the reason it's dirty in the first place.
No aggressive blasting. No spray-and-pray. No hiding damage beneath fresh paint.
Every project begins with a survey. Every survey is free. Every quote is written. Every method is agreed before work commences.
Working on listed buildings and conservation areas across London. Heritage-approved methods including DOFF, TORC, and poultice. Each method chosen for the building — never for convenience.
Portland, Bath, York, limestone, sandstone, granite. Method selected to the substrate — never defaulting to pressure where pressure will cause damage.
Learn more →London stock, red rubber, engineering, handmade brick. The most common cleaning job in the city. Also the most often done wrong.
Learn more →Heritage-approved methods for listed buildings and sensitive substrates. DOFF: superheated low-pressure steam. TORC: micro-abrasive. The right tool for the right material.
Learn more →Masonry paint, limewash, graffiti, historic coatings. Removed without damage to the substrate beneath. The building always comes first.
Learn more →Lime and cement mortar, colour-matched, joint profile and texture matched to the original. No grinding beyond what the mortar joint requires.
Learn more →Listed buildings and conservation areas. Methods agreed with conservation officers. Minimum-intervention philosophy. A written record on completion for your building's file.
Learn more →Nothing is quoted blind. Every project begins with a free site visit. The substrate is examined, the soiling identified, the access and surroundings assessed. Only then is a method proposed and a written quote issued. A small test clean is carried out on every project before full work commences.
On site, in person. Every project begins with a visit. The substrate is examined, the soiling identified, the access and surroundings assessed. Free of charge, no obligation.
Before full work commences, a test clean is carried out on a small patch. The method is calibrated to the building. If the result isn't right, the method changes — not the building.
Work proceeds to the agreed method and specification. The founder is on site throughout. Before and after photographs are taken at every stage. Progress is documented.
A written record of the methods used is provided on completion. Useful for listed building files, estate records, or insurance purposes. The building is left clean, documented, and ready.
Portland stone is porous. High-pressure water drives contamination deeper into the surface rather than removing it. The damage is often irreversible. Here is what to do instead.
Read →Two heritage-approved cleaning methods. Both gentle. Neither interchangeable. The choice depends on the substrate, the soiling type, and the depth of contamination. This is how we decide.
Read →Victorian London stock brick is softer than modern brick. It responds differently to water, chemicals, and abrasion. Most contractors do not account for this. The results are not recoverable.
Read →The founder — a specialist with twenty years on the tools, learning the craft and processes — leads every project personally. Not a managed crew. Not a franchise. The same expert on every job.
When you call Trebor, you speak to the person carrying out the work. When the scaffolding goes up, that person is on site. Not a project manager. Not a foreman relaying instructions.
This matters on listed buildings. It matters when the conservation officer has questions. It matters when the stone behaves differently than expected mid-project and the method needs to change — and it needs to change in that moment, not after a phone call to someone who isn't there.
Trebor takes on projects across London and the South East where the material, the building, and the standard of care all require a specialist rather than a contractor.
Nothing is quoted blind. Tell us about the building and we will arrange a visit, carry out a survey, and issue a written quote. No obligation.
