Jet washing, chemical cleaning and DOFF · Bath

DOFF cleaning in Bath.

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 Bath and Somerset. Facade cleaning, frame restoration and commercial decorating across Bath. A World Heritage city of Bath stone and listed Georgian frontages means heritage-safe methods come first. DOFF steam cleaning over pressure, sympathetic finishes, and restoration before replacement on period metalwork and shopfronts.

Bath 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 · Bath

What clients in Bath usually ask first.

Is your cleaning safe for Bath stone and listed facades?

Yes. DOFF superheated steam at low pressure lifts soiling without abrading the stone. We sample-clean a test area and agree the method before touching the elevation.

Do you work in the conservation area and on listed buildings?

Regularly. We work to the substrate and the consent conditions, and flag anything that needs listed-building or planning sign-off before we start.

Can you match heritage colours on shopfronts?

Yes. We identify the existing colour and apply a matched RAL or BS finish, restoring period metalwork rather than replacing it where the substrate is sound.

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.
