Kensington Stone Cleaning And Restoration
Revive the Natural Texture, Warmth & Character of Your Stone
Sandstone brings a natural, earthy beauty to both traditional and modern properties. Its warm tones, layered texture, and organic finish make it a popular choice for exterior paving, entrances, patios, and heritage interiors across London.
But sandstone is also highly porous and exposed — which means it absorbs dirt, moisture, algae, and pollution over time. Without specialist care, it can quickly become dark, stained, slippery, and uneven in appearance.
At Kensington Stone Restoration, we provide expert sandstone cleaning and restoration services throughout Kensington and Greater London. We carefully remove deep contamination, restore natural colour, and protect the stone for long-term durability.

When Sandstone Needs Professional Restoration
Sandstone doesn’t fail suddenly — it deteriorates gradually.
Typical signs include:
* Darkened or patchy surface areas
* Green algae or moss growth (especially outdoors)
* Loss of natural colour definition
* Slippery or unsafe walking surfaces
* Embedded dirt that cannot be cleaned normally
* Water staining or damp marks
* Weather erosion on exterior stone
These issues require more than pressure washing or surface cleaning — they require controlled stone restoration.

Specialist Sandstone Cleaning – Beyond Surface Washing
Sandstone is soft compared to granite or marble, which means aggressive cleaning methods can permanently damage the surface.
We avoid harsh pressure washing that strips the stone. Instead, we use controlled low-pressure systems combined with stone-safe cleaning solutions designed specifically for porous materials.
Our approach restores the stone without weakening its structure.
Frequently Asked Questions

Is pressure washing safe for sandstone?
