Granite is one of the most durable and visually striking natural stones used in luxury residential and commercial spaces. Known for its strength, crystalline beauty, and resistance to heat and wear, granite is commonly installed in kitchens, lobbies, staircases, countertops, and high-traffic flooring areas.
But even granite—despite its reputation for hardness—is not immune to damage over time. Foot traffic, abrasive cleaning methods, staining, dulling, and surface contamination can gradually reduce its natural brilliance.
At Kensington Stone Cleaning & Restoration, we specialise in restoring granite surfaces back to their best possible condition. Since 2012, we have worked on high-end granite installations across London, delivering precision restoration work that enhances both appearance and performance.
Our approach is controlled, technical, and tailored—because granite restoration is not about force, but accuracy.
Granite behaves differently from softer natural stones. While it is extremely hard, it can still suffer from:
* Surface dulling
* Micro-scratches
* Loss of polish
* Resin degradation
* Etching in certain finishes
* Staining in porous variants
* Edge chipping and impact damage
Our technicians are trained specifically in stone behaviour and restoration chemistry, allowing us to treat granite with the correct combination of mechanical refinement and surface protection systems.
Every project begins with understanding the exact type of granite and its existing finish.

Before any restoration begins, we carry out a full inspection to identify:
* Granite composition and density
* Factory finish type (polished, honed, flamed, leathered)
* Level of wear and scratching
* Staining or contamination
* Edge and joint condition
* Sealer presence and breakdown
* Shine consistency and reflectivity loss
This allows us to design a restoration process that is precise, safe, and effective.

Deep Granite Cleaning
Over time, granite surfaces accumulate layers of dirt, grease, cleaning product residue, and environmental contamination.
Our professional cleaning process removes:
* Embedded dirt and grime
* Grease and oils (especially in kitchens)
* Soap and chemical residues
* Surface contaminants
* Old maintenance product build-up
We use stone-safe systems that lift contamination without damaging the integrity of the granite surface.
The result is a clean foundation that reveals the true condition of the stone.
⸻
Granite Surface Refinement & Restoration
While granite is extremely durable, its appearance depends heavily on the condition of its polished surface.
We restore granite through controlled refinement processes designed to:
* Remove fine scratches
* Restore clarity and reflection
* Improve colour depth
* Even out surface inconsistencies
* Revive worn or tired finishes
This stage is highly technical and requires precision equipment and experience to ensure the natural crystal structure of the granite is preserved.
⸻
Granite Polishing
Granite polishing is a specialist process that restores its signature reflective finish.
Depending on the desired look and environment, we can achieve:
* High-gloss mirror finish
* Soft satin finish
* Natural refined sheen
Polishing enhances the depth, colour variation, and crystalline sparkle that granite is known for, transforming dull surfaces into visually striking features.
Each finish is carefully controlled to match the style of the property and the original stone intent.
⸻
Granite Honing & Matte Finishes
Not all granite is designed to be highly polished.
In modern interiors, honed or matte finishes are increasingly popular. These finishes offer a more subtle, contemporary aesthetic.
Our honing process can:
* Reduce surface shine
* Remove minor imperfections
* Create a smooth matte texture
* Deliver a modern architectural finish
This is ideal for clients seeking a softer, understated granite appearance.
⸻
Granite Scratch & Damage Removal
Even though granite is one of the hardest natural stones, it can still suffer from damage over time.
We repair and reduce:
* Fine surface scratches
* Deep abrasion marks
* Edge chipping
* Impact damage
* Surface dull patches
Using controlled diamond refinement techniques, we restore consistency and improve overall visual quality.
⸻
Granite Stain Treatment
Certain granite types—especially lighter or more porous varieties—can absorb liquids if not properly sealed.
We treat and reduce stains caused by:
* Oils and grease
* Food and drink spills
* Water penetration
* Organic staining
* Chemical exposure
Where possible, stains are significantly improved or removed without altering the natural appearance of the stone.
⸻
Granite Edge & Surface Repairs
Damage to granite edges and corners is common in busy environments.
We offer professional repair solutions for:
* Chipped edges
* Cracked sections
* Surface fractures
* Joint and seam damage
Repairs are carefully colour-matched and blended to ensure a discreet, high-quality finish that maintains the integrity of the stone installation.
⸻
Granite Sealing & Protection
Although granite is less porous than other natural stones, sealing is still an important part of long-term protection.
We apply premium-grade stone sealers designed to:
* Reduce staining risk
* Protect against moisture penetration
* Extend surface lifespan
* Maintain finish quality
* Simplify maintenance
Sealing is especially important in kitchen and high-use commercial environments.
We restore granite surfaces in luxury residential settings including:
* Kitchen worktops
* Bathroom surfaces
* Hallways and floors
* Staircases
* Feature walls
* Fireplace surrounds
We work carefully within private homes, ensuring minimal disruption and maximum attention to detail.
We also provide specialist granite restoration services for commercial environments such as:
* Hotels and receptions
* Office buildings
* Luxury retail spaces
* Restaurants and bars
