About Harte Stone & Brick
Harte Stone & Brick provides specialist stone and brick restoration in London for period homes, commercial buildings, residential blocks and listed properties. The company works with homeowners, freeholders, managing agents, architects, surveyors and main contractors on individual masonry repairs and complete façade restoration programmes. Work is planned around the existing building fabric, with stone, brick, mortar, render and cleaning methods selected to suit the surface and the condition of the elevation.
Stone Restoration
Stone restoration includes the repair and replacement of damaged external stonework, from window sills and cornices to corbels, columns, capitals and ornamental mouldings. Where possible, repairs retain the original stone. When replacement is necessary, new elements are selected, cast or carved to match the existing material and profile as closely as practical.
Brick Restoration
Brick restoration addresses spalled, fractured, damaged or poorly repaired brickwork. Depending on the condition, work may involve local repairs, cutting and splicing, replacement bricks, rebuilding details and colour tinting. The aim is to restore the wall's appearance while using materials and repair methods appropriate to the surrounding masonry.
Lime Repointing
Repointing renews deteriorated mortar joints and helps the wall manage moisture. Existing mortar and joint profiles are assessed before work begins, with traditional lime mortar used where appropriate for the original building fabric. Hand-raking and carefully matched mixes help preserve the character of period brickwork and stonework.
Stucco and Rendering
Stucco and rendering services cover the repair, renewal and reproduction of external finishes and architectural detailing. Work can include repairing damaged stucco, renewing defective render, reinstating mouldings and removing render where the original brickwork needs to be revealed. The appropriate approach depends on the existing coating and the condition of the substrate beneath it.
Brick Cleaning
Brick cleaning removes soot, pollution, paint, algae and other surface deposits using methods selected for the type and condition of the brick. The company describes using specialist cleaning systems including TORIK and DOFF. Test areas are used to help establish a suitable method before wider cleaning proceeds.
Stone Cleaning
Stone cleaning is approached with care because natural stone can be damaged by unsuitable pressure, abrasives or chemicals. The stone type and soiling are assessed before cleaning, with particular consideration given to Portland stone, Bath stone, limestone and carved architectural details. The aim is to remove deposits without unnecessarily eroding the original surface.
Stone and Brick Cleaning
For buildings with mixed masonry, cleaning can form part of a wider restoration programme. Different surfaces may need different techniques, especially where stone dressings sit alongside brickwork, stucco or render. Cleaning can also reveal defects that were previously hidden by dirt or coatings, helping establish whether further repair or repointing is required.
Façade Restoration
Façade restoration brings together the repair and cleaning of a building's external envelope. Work may include stone and brick repairs, repointing, render and moulding reinstatement, and carefully sequenced cleaning. Treating the elevation as a whole helps coordinate related defects and avoid carrying out separate repairs in an unsuitable order.
Listed Building Restoration and Conservation
Listed and heritage buildings require repair methods that respect their original materials and architectural details. The company works on Grade I and Grade II listed buildings, using traditional materials and conservation-led methods suited to the existing fabric. Mortar, stone, joint profiles and cleaning methods are considered in relation to the building's character and conservation requirements.
Stone Repair and Replacement
Where stone has weathered, fractured or deteriorated, the appropriate repair depends on the extent of damage and the condition of the surrounding masonry. Local repair may be possible in some areas, while severely damaged sections may require replacement. Matching the stone and the original profile helps new work sit naturally alongside the retained fabric.
Architectural Moulding and Masonry Repairs
Architectural details such as cornices, capitals, corbels, columns and ornamental mouldings need careful assessment and skilled repair. Damaged details may be repaired, recast or reproduced to match surviving features, depending on the original material and extent of deterioration.
Period Property Restoration
Georgian and Victorian terraces, mansion blocks and other older buildings often combine brick, stone, lime mortar, stucco and render. Restoration work considers how these materials interact, with methods selected to preserve the building's character and address the underlying causes of damage rather than only its visible symptoms.
Commercial and Residential Building Restoration
Harte Stone & Brick works on private residences, occupied residential blocks, commercial frontages and larger institutional buildings. Project planning can account for access, sequencing and the needs of people using the building while masonry repairs and façade works are carried out.
Survey, Specification and Repair Planning
Restoration begins with an assessment of the existing fabric and the condition of the elevation. Stone type, brick condition, mortar, render and previous repairs inform the proposed scope. Cleaning trials and material matching help establish suitable methods before work is undertaken across a larger area.
London and Home Counties Coverage
The company describes working across central, north, south, east and west London and the Home Counties. Projects include period homes, listed buildings, residential blocks and commercial properties. The precise scope and availability for each location can be confirmed when a project is assessed.
