Jet washing, chemical cleaning and DOFF · London

DOFF cleaning in London.

DOFF superheated steam, chemical, jet wash and soft-wash cleaning for facades, cladding and hard surfaces. Method chosen to the substrate. Heritage-safe is the default, not an upgrade. Delivered across London and Greater London. Commercial decorating, on-site spraying and shopfront restoration across London. Most of the London programme is overnight and phased delivery for retail estates and main contractors. Oxford Street and Westfield units through to office fit-outs in the City. All worked around trading hours.

Why London

Why choose us for jet washing, chemical cleaning and doff in London and Greater London.

Track record

  • DOFF-trained operatives. Heritage-safe superheated steam as the default for sensitive substrates
  • Substrate-matched chemistry, not a one-pressure-fits-all approach
  • Often the first phase of a cladding or restoration package, with handover directly into coating works

Right fit when

  • 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.

London programme

How we run jet washing, chemical cleaning and doff schemes locally.

  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; chemical biocide for biological growth; jet wash for hard surfaces where pressure won't damage; soft-wash where pressure and chemistry both need controlling. Run-off pH and disposal route set out.

  3. 03 · RAMS

    Project-specific RAMS: 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.

Frequently asked · London

What clients in London usually ask first.

Are you based in London?
We're a southern-England contractor with a standing London programme. Mobilisation is typically same-week, with surveys inside 48 hours.
Can you work out-of-hours in central London?
Yes. Most of our London work is overnight or phased around live trading. The cost model assumes night works, not a variation bolted on later.
How do you handle ULEZ and the congestion charge?
All site vehicles are ULEZ-compliant. Congestion charge and parking sit inside the cost model from the start.
Is DOFF safe for heritage stone and brick?
Yes. Superheated steam at low pressure removes soiling without abrading the substrate. We sample-clean a test area and agree the result before proceeding.
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 re-coating, 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.
