The service

What Is Stone Blast Cleaning?

Stone blast cleaning is the controlled removal of soot, paint, biological growth, render and pollution staining from stone facades using a fine media stream — soda, low-pressure grit or superheated steam (superheated steam) — matched to the stone type. Done right, the surface underneath is revealed intact. Done wrong, you're left with pitting, opened pores and a stone that re-soils in a season.

Materials

Stone Types We Clean

Sandstone

Soft dressed sandstone across Preston, Lancaster and civic Manchester. Default method: superheated steam.

Gritstone / Millstone Grit

Coarse Pennine stone across Rossendale, Bolton, Burnley and the moors. Default: superheated steam or soda; never heavy abrasive.

Limestone

Ribble Valley and Lancaster limestone — chemically reactive, we never use acidic chemistries.
Methods

Methods We Use — And How We Choose

superheated steam Steam Cleaning

Superheated (150 °C+) low-pressure water. Our default on soft sandstone, limestone and Grade I/II* fabric.

Soda Blasting

Sodium bicarbonate media — gentle enough for timber, glass and soft brick. Water-soluble, biodegradable.

Abrasive / TORC Blasting

Fine controlled abrasive at low pressure for hard engineering brick and steel prep.

Common Problems We Fix

  • Paint and masonry paint removal from historic stone
  • Cement render lifted from soft sandstone
  • Biological growth, lichens and moss
  • Soot, sulfation crusts and pollution staining
  • Graffiti removal without ghosting
  • Efflorescence and soluble-salt discoloration

Questions

Frequently Asked Questions

Will blast cleaning damage my stonework?

Not if the method matches the stone. superheated steam and soda blasting are gentle enough for soft sandstone and limestone; heavy dry abrasive is not. We survey the stone type, dress and condition first — and we test on a small unobtrusive patch before the whole facade.

How do you choose the right method for my stone type?

We identify the stone, note its condition (weathering, previous repairs, coatings) and the substrate underneath, then default to the gentlest method that will actually remove what needs removing. Soft sandstone and limestone: superheated steam. Gritstone: superheated steam or soda. Hard engineering stone with heavy coatings: fine abrasive at controlled pressure.

Do you need permission to clean a listed stone building?

In most cases, yes — Listed Building Consent is required for anything that could affect the character of a listed building, and blast cleaning almost always does. We can help you scope the application and supply the method statement and product data your council's conservation officer will want to see.
