Bricklayer quick-view
Brick cleaning ranges from gentle scrub-and-rinse for biological growth to specialist chemical treatment for paint, graffiti, or salt damage. The wrong method destroys soft brick faces and joints. This guide covers what brick cleaning costs in 2026, the methods available, and which suits which problem.
Older soft bricks need gentler methods than modern hard ones. Match the method to the brick.
Methods & Suitability
- Soft brush + water — algae, moss, light dirt on soft bricks.
- Low-pressure washing — moderate dirt; safe on most bricks.
- Chemical cleaning (acidic) — efflorescence, lime stains; risk to soft brick.
- Chemical cleaning (alkaline) — soot, paint, biological growth.
- JOS / TORC blasting — gentle mechanical for heritage cleaning.
- Sandblasting — last resort; destructive but effective for very dirty hard bricks.
- Steam cleaning — paint removal, gentle on most surfaces.
Typical Costs
| Method | Low £/m² | High £/m² | Notes |
|---|---|---|---|
| Soft wash & brush | 10 | 25 | Algae and light dirt |
| Chemical clean (acidic) | 20 | 45 | Efflorescence, lime staining |
| JOS / TORC heritage cleaning | 40 | 120 | Gentle mechanical |
| Sandblasting | 30 | 80 | Aggressive; modern brick only |
| Paint removal | 40 | 100 | Specialist work |
| Graffiti removal | 30 | 120 | Per affected area |
How Long Does It Take?
- Standard back wall (30 m²): 1–2 days.
- Full façade with chemical: 3–5 days.
- Heritage JOS cleaning: 5–10 days for full façade.
DIY or Professional?
Soft washing achievable for confident DIYers. Chemical and mechanical methods need specialists due to handling, ventilation, and waste disposal.
Choosing the Right Tradesperson
- Confirm method matches your brick type.
- Test patch first — small inconspicuous area.
- For heritage, look for JOS/TORC-trained specialists.
- Confirm waste disposal plan (chemical/contaminated water).
UK Regulations
- Listed properties: consent often needed for cleaning.
- Conservation areas may restrict methods.
- Environment Agency restrictions on chemical waste.
Common Problems
- Wrong method for brick — sandblasting Victorian brick destroys it.
- Damage to mortar — aggressive cleaning removes joints as well as dirt.
- Inadequate rinse — chemical residue continues to damage.
- Listed building damage — consent breach + irreversible damage.
- Iron staining brought to surface — chemical reveals previously hidden problems.
Frequently Asked Questions
Can I jet-wash my brickwork?
On hard modern brick yes, low setting. On Victorian or softer brick, use only soft brush — pressure removes the face.
What's JOS cleaning?
Specialist heritage system using fine inert aggregate at low pressure with water. Gentle enough for soft heritage brick.
How often should I clean my brickwork?
Every 10–20 years if visible. More often if heavily polluted or shaded (algae build-up).
Will cleaning damage the brick?
Done correctly no. Wrong method or chemicals definitely.
Can painted brick be unpainted?
Yes — chemical paint removal. Specialist work; some paint removes cleanly, some doesn't.
Does brick cleaning add value?
Yes — clean brickwork dramatically improves property appearance. Marketed homes often have this done before sale.
