Expert Guide to Bath Stone & Exterior Surface Cleaning in Bristol and Bath
In the South West, beautiful homes and buildings often feature Bath stone and other delicate exterior surfaces. From the classic honey-coloured terraces of Bath to the elegant properties of Clifton, Redland and Westbury-on-Trym in Bristol, these stone facades and patios are stunning when cared for – but they’re also prone to algae, staining and weather damage. In this blog, we’ll share professional advice on caring for Bath stone, patios, and driveways, why soft-washing is the safest method, and how sealing or protective treatments can preserve your investment for years.
Why Bath Stone Needs Specialist Care
Bath stone is a soft oolitic limestone. While it looks fantastic, it’s porous and delicate, meaning it can easily absorb moisture, dirt and pollutants. Over time this leads to:
- Algae and moss growth – turning walls or patios green and slippery
- Black staining from lichen – particularly common in shaded or damp areas
- Pollution discolouration – especially on older city properties
- Surface erosion if high-pressure washing is used incorrectly
That’s why specialist methods are vital. Bath stone should never be blasted with harsh jet washing – it risks etching, spalling and permanent damage. The correct approach is professional soft-wash cleaning using gentle, low-pressure rinsing and carefully chosen biocidal treatments.
Our Soft-Wash Method (Safe & Effective)
We are specialists in Bath stone and exterior cleaning across Bristol and Bath. Our soft-wash process is designed to clean deeply but safely:
- Assessment – Identify the stone type, pointing condition and staining issues.
- Pre-treatment – Apply a professional biocide to kill algae, moss and spores at the root.
- Low-pressure rinse – Remove dirt, staining and organic growth without harming the surface.
- Detail work – Gently clean intricate stonework, sills and edges by hand if needed.
- Optional protective treatment – Apply breathable stone sealer or water-repellent to slow regrowth and protect against pollutants.
This approach ensures Bath stone and other soft masonry is restored to its natural colour without risk of damage.

Seasonal Maintenance Tips
- Spring: Ideal for a deep clean after winter moss and algae buildup. Perfect time to prepare for outdoor entertaining.
- Summer: Best season for sealing patios, driveways and stone – warm, dry conditions ensure perfect application.
- Autumn: Clear fallen leaves quickly – tannin stains can mark stone and paving.
- Winter: Keep surfaces swept and safe. Frozen algae can turn decking and stone dangerously slippery.
Regular cleaning and sealing means your surfaces stay safe, attractive and easier to maintain year-round.
