Specialist restoration services for heritage buildings

Heritage properties need bespoke care, and restoration isn’t one-size-fits-all. Our services are tailored specifically for historic and listed buildings across the UK:

Heritage damage assessment & planning
Detailed evaluation aligned with conservation standards before restoration begins.

Fire & smoke damage conservation
Removing soot, ash and odours using methods that preserve historic materials.

Preservation & conservation you can trust

Historic buildings have unique vulnerabilities. Simply cleaning or repairing damage isn’t enough, it must be done in a sympathetic, conservation-aligned way. We prioritise:

  • Conservation-aware techniques: Using DOFF, TORC and other gentle cleaning systems approved for heritage materials.
  • Material integrity: Respecting stone, brick, timber and lime-based substrates during restoration.
  • Sustainable practices: Environmentally responsible methods that protect both the building and its surroundings.
  • Sector expertise: Technicians trained specifically in heritage building protocols and UK standards.


This approach protects the authenticity and historical value of buildings while restoring them.

Heritage building cleaning services: Frequently asked questions

What is heritage building cleaning, and why is it important?

We provide expert fire, water, and environmental cleaning services for heritage properties. Ensuring they remain safe, structurally sound, and visually impressive. Heritage cleaning isn’t a service in itself but rather who we cater our range of services to. For heritage properties in the UK affected by the likes of fire, water an environmental disaster our team provide the services in a way that protects your property and maintains strict adherence to UK conservation standards.

We use non-invasive, conservation-approved techniques such as steam cleaning, DOFF and TORC systems, and gentle chemical treatments designed for historic materials. These methods effectively remove dirt, algae and carbon staining without damaging delicate stone, brick or timber surfaces. Our approach will vary depending on the service you need but always follows UK heritage conservation standards to ensure the building’s integrity is maintained.

Yes, we offer a range of specialist cleaning services that include the removal of graffiti, moss, algae, lichen and pollution-related staining using gentle but effective cleaning techniques. We ensure all treatments are suitable for historic stonework and brick to prevent damage while restoring the building’s appearance. Our work aligns with UK conservation principles to protect the character of heritage properties.

The frequency of cleaning depends on factors such as location, environmental exposure and pollution levels. Urban buildings may require cleaning every 510 years due to air pollution, while rural structures might need less frequent maintenance. If the heritage property has been affected by disaster in the form of fire, water or the environment then you may just need a one-off clean to restore it back to its pre-incident condition.

We’ve got over 20 years’ experience providing our fire, water and environmental services to heritage buildings. From removing graffiti off St Pauls cathedral to specialist cleaning within a Grade II listed building following a fire, as well as working with English Heritage directly.  

We use specialist, non-invasive cleaning systems such as DOFF and TORC that lift stains without damaging fragile substrates.
