Cast Stone Graffiti Removal London
We remove graffiti from cast stone and reconstituted stone across London, with the method matched to the concrete and aggregate your frontage is actually made from. Window surrounds, balustrades, copings, porticos, planters and whole facades built to look like Portland. Our crews can attend within three hours of your go-ahead, seven days a week, and we identify the material before we set a fixed price, so the method in your quote is the right one.

Cast Stone Graffiti Removal, Identified Before We Quote
Cast stone frontages are easy to get wrong, because the material is concrete made to look like natural stone. It is moulded rather than carved, with crushed stone and sand in the mix to give it the colour and texture of Portland, Bath or York stone. From the pavement it can be almost impossible to tell apart from the real thing.
That matters because it does not behave like the stone it copies. The cement binder reacts to cleaners differently, the surface can be softer or harder than it looks, and older mixes can soak up paint like a sponge. Treat it as Portland and the result can be patchy. Treat it as ordinary concrete and the fine face can be scoured away.
So we work out what your frontage is made of first. You do not need to know. Give us the address with your quote request and we will do the rest.

Cast Stone On London Frontages
Cast and reconstituted stone is far more common in London than most owners realise. We are booked to clean it on:
- Inter-war offices and shopping parades with cast stone facades and window dressings.
- Victorian and Edwardian houses with cast stone lintels, sills, bay windows and porches.
- Balustrades, copings, pier caps and garden walls on residential estates.
- Planters, benches and bollards in retail parks, squares and business districts.
- Newer apartment blocks and hotels finished in reconstituted stone panels.
One of the best-known examples is Olympia, the exhibition centre on Hammersmith Road. Its listing records that "The front range has a reconstructed stone facade manufactured from concrete with a Portland stone aggregate." A building like that looks like Portland, is quoted as cast stone, and gets a method chosen for it.

What Goes Wrong On Reconstituted Stone
| Acid-based cleaners | Attack the cement binder and the limestone aggregate, leaving a rough, sandy face. |
| High-pressure washing | Strips the fine surface layer and exposes the coarser aggregate beneath, which never matches again. |
| Grit blasting | Erodes arrises and moulded detail that was cast in, not carved, and cannot be recut. |
| Solvent left to soak | Carries the paint deeper into older, more porous mixes. |
Porosity is the hidden risk. Historic England notes that "Historic concrete (based on lime or cement) can be significantly more permeable than the modern material." On a pre-war facade, that means paint travels further and needs drawing out, not chasing with pressure.
How We Remove Graffiti From Cast Stone
- We confirm the material and how it has weathered before we price.
- We test on a small area so you can see the result and approve it.
- We lift fresh paint with superheated steam at very low pressure, using our DOFF system.
- We poultice older or deeper marks so the pigment is held and lifted, not spread.
- We blend the cleaned area so the surface texture matches the panels around it.
Where cast stone sits next to real Portland or limestone, our Portland stone graffiti removal and limestone graffiti removal crews switch method at the joint on the same visit.

Who We Clean Cast Stone For
- Managing agents with inter-war blocks and parades faced in reconstituted stone.
- Housing associations and residential estates with cast stone walls and porches.
- Hotels, venues and offices finished in modern reconstituted panels.
- Councils and business districts with cast stone street furniture.
Repeat Tags On The Same Panels
Cast stone planters, walls and plinths at street level tend to be hit again and again. Once the surface is clean, a breathable anti-graffiti coating means the next tag sits on the coating instead of in the concrete. We can clean and coat in one visit, and we will tell you if the site is not hit often enough to justify it.
Paperwork That Clears Procurement
Managing agents and estates buying cast stone cleaning usually need more than a price. Each quote from us arrives with a method statement naming the treatment for your mix, a site-specific risk assessment, COSHH data for each product and a copy of our insurance certificate. After the job you receive a completion report with the date, the method and the finish, ready to attach to a service charge invoice.
Your Price, Set Before We Start
You get one fixed figure for the job. It covers identifying the material, the trial, the clean, any poultice return visit, access and a completion report. There is no survey fee and quoting is free. We bring our own water and power, so nothing is taken from your building and nobody needs to meet us.

Cast Stone Graffiti Removal: Frequently Asked Questions
How Much Does Cast Stone Graffiti Removal Cost?
The figure depends on the mix, the area of the tag and how we reach it. We set one fixed price once the material is identified, at no charge.
How Fast Can You Attend?
We can have a crew there within three hours of your go-ahead, seven days a week.
How Do You Know If Our Frontage Is Cast Stone?
We identify it for you at quote stage from the address and building details. You do not need to know in advance.
Is Cast Stone Cleaned The Same Way As Portland?
No. The binder and aggregate need their own method, which is why we confirm the material first.
Will The Surface Texture Change?
Not with our methods. We work at very low pressure and blend the finish into the surrounding panels.
Can You Clean Cast Stone Planters And Benches?
Yes. Street furniture in squares, estates and retail parks is a regular part of our cast stone work.
Does Anyone Need To Be On Site?
No. We are self-contained and send a completion report afterwards.
