Jet washing, chemical cleaning and DOFF · Oxford

DOFF cleaning in Oxford.

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 Oxford and Oxfordshire. Facade cleaning, restoration and commercial decorating across Oxford. A city of college stone, listed frontages and the Westgate retail estate. Heritage-safe DOFF cleaning, sympathetic restoration of period metalwork, and retail and commercial decorating worked around a tight, pedestrianised centre.

Oxford 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 · Oxford

What clients in Oxford usually ask first.

Can you clean college and heritage stone safely?

Yes. DOFF steam at low pressure removes soiling without harming the stone; we sample first and work to any conservation conditions.

Do you work in Oxford's pedestrian centre?

Yes. Access, deliveries and out-of-hours working are planned around the centre's restrictions and agreed before we mobilise.

How far do you cover around Oxford?

Oxford city plus Bicester, Abingdon, Witney and the business parks along the A34 and M40 corridor.

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.
