DOFF, abrasive cleaning, chemical and jet wash for commercial facades.

DOFF superheated steam, gentle abrasive cleaning, chemical, jet wash and soft wash cleaning for facades, cladding and hard surfaces, and for residential exteriors: period brick, natural stone, patios, driveways and block paving. Method chosen to the substrate. DOFF and TORC are delivered by our specialist partner inside the A Star package, under our RAMS.

When this is the right route

  • The facade or cladding is dirty but otherwise sound. Clean first, then assess for coating.
  • The substrate is heritage stone, terracotta or sensitive brick that pressure washing would damage.
  • Cleaning is a preamble to cladding coatings, powder coat restoration or a final account condition record.
  • Your patio, driveway or block paving has black spot, lichen, moss or ingrained staining a domestic pressure washer cannot shift.
  • You own a period or listed home in brick, stone or render that needs a heritage safe clean without grit blasting or harsh chemicals.

Scope · included

  • DOFF superheated steam system cleaning
  • Gentle abrasive cleaning for carbon staining, paint and limescale
  • Chemical biocide and run off specification per substrate
  • Jet wash and softwash where appropriate
  • Run off containment and cleaning record
  • Residential patio cleaning by pressure wash, rotary head or chemical soft wash as appropriate
  • Driveway and block paving cleaning with re sanding after wash
  • DOFF steam cleaning for period brick, stone and listed residential exteriors
  • Biocide treatment to slow regrowth on residential surfaces

Scope · not included

  • Coating application (separate scope and spec)
  • Stone repair and crack injection
  • Pointing and regrouting
  • Garden landscaping, planting or fence painting

Process

  1. 01

    Survey

    Substrate type confirmed (stone, brick, render, cladding), soiling type assessed (atmospheric, biological, paint, soot), test area agreed with client. Pressure or steam method confirmed before any work begins.

  2. 02

    Specification

    DOFF steam for heritage or sensitive substrates; gentle abrasive cleaning where carbon sulphation, ingrained staining, paint or limescale will not shift with steam alone; chemical biocide for biological growth; jet wash for hard surfaces where pressure won't damage; softwash where pressure and chemistry both need controlling. Run off pH and disposal route set out.

  3. 03

    RAMS

    RAMS written for the project: chemical handling, PPE matrix, run off containment plan, exclusion zones during application, pedestrian and vehicle protection. COSHH for any biocide or neutraliser.

  4. 04

    Delivery

    Containment bunded, test area cleaned and signed off by client, full application by elevation. Neutraliser applied where chemical spec calls for it. Public access protected throughout.

  5. 05

    Handover

    Before/after photo record, cleaning record (method, products, pH readings where relevant), condition note if coating or restoration work is to follow.

Case study

Primark · Stevenage (Phase 1)

Town Square, Stevenage · Restoration

We restored the outside of Primark's town centre store in Stevenage for R.G. Carter. Each surface needed its own method. We finished in June 2026, in seven weeks.

Built for the people who buy decorating

Three audiences. One delivery model.

We are a specialist subcontractor, not a turnkey fit out outfit. We deliver decorating, spraying, restoration and coatings under main contractors and direct estate teams.

For main contractors

Hands-on decorating, phased around live sites.

Variations are agreed in writing and delivered without delaying handover. You get a handover record for each store.

  • Repeat work for Uplands Retail, R.G. Carter and Morris & Spottiswood
  • Variations agreed in writing and delivered without delaying handover
  • Per zone handover record across multi store programmes

For estate + FM teams

Live trading stays live. Restoration before replacement.

Survey to handover without closing the unit. Powder coat restoration is specified to the surveyed substrate. Run off, masking and reopening tracked store by store.

  • Out of hours + phased delivery on rolling estate programmes
  • Photo led handover record per store / per elevation
  • Cleaning before any coating, with DOFF steam cleaning by our specialist partner under our RAMS

For retail estate leads

Brand consistency, store by store, against the agreed programme.

We match the paint system to your brand and estate specification. You get progress and handover records for each store. If the timetable moves, we tell you early and replan with the site team.

  • Rollouts across many stores, with records for each one
  • Brand matched Dulux Trade specifications
  • Repeat work in Primark, Tesco and M&S stores

How we deliver

Built for live UK sites.

Every job is director-led. You deal with one contact and one timetable, from survey to handover.

01

Live trading hours

Frequently asked

  • Is DOFF safe for heritage stone and brick?

    Yes. It uses very hot steam at low pressure, so it lifts dirt without wearing the surface away. Our specialist partner cleans a test patch first, inside the A Star package and under our RAMS, and we agree the result with you before going further.

  • What is TORC cleaning and when do you use it instead of DOFF?

    TORC is Stonehealth's gentle rotating vortex system: low air pressure, a little water and a fine inert granulate. We use it where steam alone will not shift the soiling, such as carbon sulphation on stone, ingrained staining on concrete, and paint or limescale removal. Like DOFF, it is delivered by our specialist partner inside the A Star package, under our RAMS. We agree a sample area before cleaning the whole wall.

  • How is run off managed?

    Contained, captured and disposed in line with the chemical spec and site drainage rules. Set out in the RAMS pack before mobilisation.

  • Will it strip existing paintwork?

    The cleaning regime is matched to the substrate. If the intention is to preserve the existing coating, we confirm that in the spec. If it's a preamble to recoating, we can strip in the same pass.

  • Can it be done at height?

    Yes. MEWP or scaffold access, chosen at survey based on elevation height and run off management requirements.

  • Why won't you quote without a site visit?

    The chemistry is substrate specific. The same stone on two different buildings can behave differently due to previous treatment, weathering or salt contamination. A site visit takes 30 minutes and prevents a specification that damages the facade.

  • Is DOFF safe for the brickwork on a period home?

    Yes. DOFF runs very hot but at very low pressure. It lifts paint, moss and soot without forcing water into the brick or wearing the face away. That is why conservation officers often ask for it on listed and period homes. A high pressure washer can soak old brick and lime mortar and damage them.

  • Can you clean a block paving driveway without washing out the jointing sand?

    Yes. We use rotary wash heads at controlled pressure that clean the block surface without excavating the kiln dried sand from the joints. After cleaning we inspect the joints and re sand where needed with fresh kiln dried silica sand. A joint stabiliser seal is available as an optional extra to hold the sand long term.

Where we can, we check access and the state of the surfaces before we price, so the quote matches the real job. Email drawings to office@astardecorators.com, or send photos on WhatsApp.
