The right method for every surface
Every patio is different. A cleaning method suitable for concrete may not be appropriate for delicate natural stone. We assess the paving before recommending the work. Our services can include:
Indian sandstone patio cleaning
We assess the stone variety and its condition before selecting a method that lifts discolouration without damaging the surface.
Porcelain patio cleaning
Suitable porcelain paving can be cleaned using methods and products appropriate to its finish and texture.
Concrete paving slab cleaning
Pressure tuned to the surface strips grime, algae and green staining from concrete paving slabs.
Suitable natural stone cleaning
A gentler, surface-specific approach for compatible natural stones that need careful handling.
Moss & algae removal
We remove suitable surface growth and biological contamination that builds up on patios over time.
Restoration & protection
Additional restoration and compatible protective treatments where appropriate to the material and condition.

Indian Sandstone Patio Cleaning
Indian sandstone is a popular choice for garden patios, but its appearance can change considerably with weathering and biological growth.
Different sandstone varieties can react differently to cleaning products and pressure. We assess the stone, joints and existing treatments before selecting a suitable cleaning method.
Porcelain Patio Cleaning
Porcelain paving can accumulate dirt, algae and residue, particularly in textured finishes and joints.
Professional cleaning can help remove surface deposits and restore a cleaner appearance without unnecessary abrasion.
Why porcelain needs care
- ✓Textured finishes trap dirt in the surface grain
- ✓Joint gaps collect organic growth and residue
- ✓Abrasive methods can dull or scratch the finish
- ✓We select products appropriate to the tile
What black spots are
- ✓Often persistent biological growth on the surface
- ✓Can embed into porous and textured paving over time
- ✓Some respond to specialist treatments, others do not
- ✓Results depend on the material and nature of the staining
Patio Black Spot Removal
Persistent dark marks can be difficult to remove using ordinary cleaning methods. Some may respond to specialist treatments, but results depend on the material and the nature of the staining.
We'll explain what's realistic before proceeding, so you know what to expect from the work.
