What heritage stone and brick restoration actually involves
Heritage restoration cleaning is the removal of soiling, biological growth, paint and staining from historic stone and brick using methods gentle enough to leave the original surface intact. In practice that means superheated water rather than chemicals, low pressure rather than high, trial patches rather than assumptions, and a written method statement the local conservation officer can agree before any work begins.
Lancashire built itself out of millstone grit, sandstone and hard-fired red brick, and most of what we clean has stood through wet westerly weather for a hundred and fifty years or more. That weather has done two things. It has laid a black sulphation crust across the sheltered areas that rain never reaches, and it has fed thick biological growth on the north and west elevations. The two need completely different handling, very often on the same wall.
One rule governs everything on a heritage job. The outer few millimetres of a weathered sandstone are the hardest and most protective part of the whole block. Abrasive cleaning takes that skin off. What is left underneath is open, soft and thirsty, and it will soil faster, hold more water and decay quicker than it ever did before anybody cleaned it. A building can look brighter the week the scaffold comes down and be in far worse condition a decade later.
That is why we work with DOFF superheated water and, where paint or graffiti is involved, the TORC vortex. Both are accepted by conservation officers and the DOFF system is approved by English Heritage. Neither leaves a chemical residue sitting in the stone. On a listed building we expect to provide a method statement, agree trial patches on the differing elevations and have the conservation officer see them before the main clean starts.
Suitable for
- Parish churches, chapels and church halls
- Listed farmhouses, manor houses and estate cottages
- Former mill buildings and industrial brickwork under conversion
- Conservation-area terraces, shop fronts and civic buildings
- Boundary walls, gate piers, sundials and memorials
- Sandstone and millstone grit elevations of any age
Problems it solves
- Black sulphation crust on sheltered stonework and carved detail
- Heavy algae, lichen and moss on north and west elevations
- Green and black staining running from failed gutters and hoppers
- Earlier abrasive cleaning that has opened up the face of the stone
- Paint, limewash or graffiti on a listed elevation
- A conservation officer who needs a method agreed before consent
How we approach heritage stone and brick restoration
Site visit and condition survey
We walk the building elevation by elevation and record stone type, the pattern of soiling, biological growth, open joints, failed rainwater goods and any damage from earlier cleaning. Photographs are kept with the record.
Method statement
A written statement sets out the equipment, temperatures, pressures and sequence we intend to use, along with protection for glass, lead, timber and planting. This is the document a conservation officer or architect will want to read.
Trial patches
Small patches are cleaned on each elevation that differs, because a sheltered south face and a wet north gable will never behave the same. Everyone agrees what an acceptable result looks like before we go further.
Access and protection
Scaffold or a suitable powered platform goes up with the building protected: leadwork covered, stained glass shielded, gravestones and planting sheeted, and drainage managed so run-off goes nowhere it should not.
Cleaning
DOFF is worked methodically across the elevation at low pressure with the water superheated at the nozzle. Where paint or graffiti is present, TORC takes it off. Soft, decayed areas are left alone and reported, never forced.
Handover and reporting
You get a record of what was done, photographs before and after, and a note of anything we found that needs a mason, a roofer or a joiner. We do not carry out repairs we are not qualified to make.
What you get
- DOFF is approved by English Heritage and accepted by conservation officers
- No chemicals left in the stone, so no salt bloom or residue afterwards
- Algae, lichen and moss spores killed by temperature rather than biocide
- The weathered outer surface of the stone is left intact
- Method statement and trial patches provided as standard
- Small hands-on team, no subcontractors on your building
