Limestone Floor Restoration – Highgate, North London
Project Overview
MGS Restoration Ltd were commissioned to undertake a full limestone floor restoration programme within a substantial private residential property in Highgate, North London, as part of a wider internal refurbishment project.
The property featured a striking grey natural limestone floor running throughout the entire ground floor level. Although the exact origin of the stone was unknown, the material displayed many of the characteristics commonly found in high-end contemporary limestone installations within London residential properties.
Over time, the flooring had suffered from staining, surface contamination, worn grout joints, and general loss of consistency caused by years of use and incorrect maintenance practices. Additional restoration works were also required to a heavily stained ground floor shower tray together with a Nero Assoluto black granite kitchen worktop.
MGS Restoration carried out a comprehensive programme of stone refinishing, specialist cleaning, grout repairs, and sealing works to restore the appearance and functionality of the stone surfaces throughout the property.
Project Details
Location: Highgate, North London
Service: Limestone and Granite Restoration
Materials: Grey Limestone, Nero Assoluto Granite
Property Type: Private Residential Property
Project Type: Internal Stone Restoration


The Challenge
The limestone floor throughout the ground floor had gradually become affected by:
-
Large surface stains
-
Embedded contamination
-
Dull and inconsistent surface appearance
-
Missing and deteriorated grout joints
Several substantial stains had remained hidden beneath large rugs for many years, leaving heavily discoloured sections across key areas of the floor.
In addition, the scale of the refurbishment works meant large quantities of furniture had to be carefully handled and relocated throughout the restoration process. This required careful coordination and protection measures to prevent damage to both the flooring and surrounding interiors.
Additional restoration works were also required within the property, including:
-
A heavily limescale-stained ground floor shower tray
-
Restoration of a honed Nero Assoluto black granite kitchen worktop
The granite worktop had become contaminated and required stripping, deep cleaning, and resealing using a specialist oil-based sealer rarely used within modern installations today.
The Restoration Process
Limestone Floor Assessment and Preparation
MGS Restoration first carried out a detailed assessment of the limestone flooring to identify:
-
Areas affected by staining
-
Missing grout joints
-
Surface inconsistencies
-
Existing finish conditions
Before restoration works commenced, our team carefully managed and relocated large furniture items throughout the property to allow safe access to all floor areas.
Special care was taken throughout the process to protect both the stone surfaces and surrounding finishes during the refurbishment works.
Diamond Refinishing of Limestone Floor
The limestone floor throughout the ground floor level was professionally refinished using specialist diamond grinding and polishing systems.
This process removed surface contamination, staining, and worn layers of stone while refining the floor to achieve a clean and consistent appearance.
The refinishing process also restored clarity and natural variation within the grey limestone, significantly improving the overall visual quality of the floor.
Grout Repairs and Reinstatement
Missing and deteriorated grout joints throughout the flooring were carefully topped up and reinstated where required.
The repaired grout lines improved both the appearance and long-term integrity of the limestone installation while helping restore consistency across the floor surface.
Shower Tray Deep Cleaning and Restoration
The ground floor shower tray had developed heavy limescale buildup and staining over time.
MGS Restoration carried out specialist deep cleaning and descaling treatments to safely remove the contamination while preserving the underlying stone finish.
The restored shower tray now presents a significantly cleaner and more refined appearance.
Nero Assoluto Granite Worktop Restoration
The property’s honed Nero Assoluto black granite kitchen worktop also underwent specialist restoration works.
Our team carefully:
-
Stripped previous surface contamination and residues
-
Deep cleaned the granite surface
-
Refinished the honed appearance
-
Applied a specialist oil-based impregnating sealer
This traditional oil-based sealer, now less commonly used in modern stone installations, was selected specifically to enhance the depth, richness, and natural character of the Nero Assoluto granite.


Materials and Techniques Used
-
Diamond limestone refinishing systems
-
Specialist limestone stain removal techniques
-
Grout repair and reinstatement methods
-
Stone-safe descaling treatments
-
Nero Assoluto granite restoration techniques
-
Traditional oil-based granite sealers
-
Specialist stone deep cleaning systems
The Results
The completed restoration successfully transformed the limestone flooring and stone surfaces throughout the property.
The diamond refinishing process removed years of staining and contamination, restoring a clean and consistent appearance across the entire ground floor limestone installation.
The repaired grout joints and restored stone surfaces significantly improved both the appearance and maintainability of the flooring.
The shower tray and Nero Assoluto granite worktop were also successfully revitalised, with the oil-based granite treatment restoring exceptional depth and richness to the black stone surface.
Together, the works delivered a refined and cohesive finish fully in keeping with the quality of this Highgate residence.
