Kensington Stone Restoration provides premium patio and outdoor stone cleaning services across London for luxury homes, gardens, courtyards, and commercial outdoor spaces.
Outdoor stone takes the hardest hit — weather, moss, pollution, and constant exposure slowly turn elegant surfaces into dark, slippery, tired-looking areas.
We restore them to their original clarity, safety, and natural beauty.
Even the highest-quality stone begins to deteriorate outdoors due to:
* Moss, algae, and lichen growth
* Black spot and organic staining
* Rainwater pollution buildup
* Oil and BBQ stains
* Dirt trapped in porous surfaces
* General weathering and fading
The result is not just visual decline — it becomes a safety risk too.
We use a specialist system designed for exterior natural stone, combining power with precision.
Our cleaning approach includes:
* Controlled pressure washing (stone-safe levels only)
* Deep biological treatment for moss & algae removal
* Stain extraction and surface purification
* Re-sanding of joints (where applicable)
* Full surface restoration wash-down
We don’t damage stone — we reset it.
Our patio and exterior stone cleaning is ideal for:
* Private Kensington gardens
* Luxury courtyard patios
* High-end terraces and balconies
* Driveways and entrance paths
* Hotel outdoor seating areas
* Designer landscaping projects
Where outdoor presentation matters as much as interiors, we deliver perfection.

1. Surface Inspection
We assess stone type, contamination level, and structural condition.
2. Deep Exterior Cleaning
We remove moss, algae, and embedded dirt using safe techniques.
3. Stain Treatment & Restoration
Targeted treatment for black spots, oil stains, and discolouration.
4. Joint & Surface Reconditioning
Re-sanding and stabilising where required for structural integrity.
5. Final Protection & Finish
We apply breathable protection to slow regrowth and staining.

After treatment, your outdoor stone becomes:
* Visibly brighter and cleaner
* Safer with reduced slip risk
* Free from moss and algae buildup
* More visually uniform in colour
* Easier to maintain long-term
Your outdoor space becomes usable, presentable, and impressive again.
We carefully treat:
* Sandstone patios
* Limestone paving
* York stone walkways
* Granite steps and entrances
* Travertine outdoor areas
* Mixed natural stone landscapes
Each surface is treated individually — never with a one-size-fits-all method.
We don’t just clean stone — we prepare it to resist future damage:
* Slows regrowth of moss and algae
* Reduces water penetration
* Minimises staining from organic debris
* Maintains natural stone breathability
* Extends overall surface lifespan
