External Stone Cleaning London & Hertfordshire
Professional External Stone Cleaning Specialists in London
External stone surfaces such as patios, driveways, pathways, and garden features are constantly exposed to weather, pollution, and biological growth. Over time these surfaces can become discoloured, slippery, and worn due to the accumulation of dirt, algae, moss, and other contaminants.
At MGS Restoration, we provide professional external stone cleaning services in London, helping property owners restore the appearance and safety of outdoor stone surfaces. Using specialist cleaning equipment and stone-safe techniques, we remove dirt, biological growth, and staining while protecting the natural structure of the stone.
Whether cleaning a residential patio, restoring York stone paving, or removing staining from a stone driveway, our professional cleaning process brings outdoor stone surfaces back to their natural appearance.
Patio Stone Cleaning
Patios are one of the most commonly used outdoor spaces in residential properties, but constant exposure to rain, organic growth, and general use can cause the stone to become discoloured and slippery.
Our patio stone cleaning service removes algae, moss, dirt, and staining from natural stone surfaces. Using carefully controlled cleaning methods, we restore the natural colour and texture of the stone while ensuring the surface remains safe and durable.
Professional patio cleaning not only improves the appearance of outdoor spaces but also helps extend the lifespan of the stone.


York Stone Cleaning
York stone is widely used in traditional paving, garden paths, and outdoor patios across London. While this natural sandstone is extremely durable, it can accumulate dirt, algae, and dark staining over time.
Our York stone cleaning process safely removes surface contaminants while preserving the natural character of the stone. By using appropriate cleaning methods designed for sandstone materials, we ensure the stone is restored without causing erosion or damage.
Cleaning York stone paving can dramatically improve the appearance of outdoor areas while maintaining the authenticity of the material.
Driveway Stone Cleaning
Stone driveways are exposed to heavy use, vehicle traffic, oil stains, and environmental pollutants. Over time this can cause discolouration and buildup that is difficult to remove with standard cleaning methods.
Our driveway stone cleaning service removes dirt, oil residues, and organic growth to restore the natural appearance of the stone surface. By using specialist equipment and appropriate cleaning techniques, we ensure the stone is thoroughly cleaned without damaging the material.
A professionally cleaned driveway improves both the appearance and safety of the property’s entrance.


Pathway and Garden Stone Cleaning
Garden pathways and stone walkways often develop moss, algae, and dirt due to constant exposure to moisture and shade. This buildup can create slippery surfaces and reduce the visual appeal of outdoor areas.
Our stone pathway cleaning service removes biological growth and surface contaminants, restoring the natural colour and texture of the stone. Cleaning pathways also improves safety by reducing the risk of slips caused by moss or algae.
Stone Surface Sealing
After cleaning, natural stone can be protected with a specialist sealer designed to reduce moisture penetration and staining. Sealing external stone surfaces helps maintain the restored appearance while protecting the stone from environmental damage.
A professional stone sealer can also make routine maintenance easier by preventing dirt and contaminants from becoming embedded in the stone.

Our External Stone Cleaning Process
1. Surface Inspection
Before cleaning begins, we carefully inspect the stone surface to determine the type of material and level of contamination.
2. Surface Preparation
Loose debris, dirt, and organic growth are removed to prepare the surface for deep cleaning.
3. Professional Cleaning
Using specialist cleaning equipment and stone-safe techniques, we remove algae, moss, dirt, and staining from the stone surface.
4. Targeted Stain Removal
Where necessary, additional treatments are applied to remove stubborn stains or heavy biological growth.
5. Optional Sealing
A protective sealer can be applied to help protect the stone from moisture and staining.
