Structural Repairs & Restorations
Stone buildings can withstand generations of weather and use, but damaged or deteriorating masonry can eventually affect the appearance, stability and integrity of a property. Clarke Heavey provides professional structural stone repairs and restoration, carefully repairing and restoring masonry while retaining the character of the existing building wherever possible.
Expert Stone Repairs & Restoration
Structural stonework can deteriorate for a number of reasons, including weathering, water ingress, movement, failed mortar and previous inappropriate repairs. Identifying the underlying issue is an important part of determining the right approach.
At Clarke Heavey, we assess the condition and construction of the existing masonry before carrying out repair and restoration work. Depending on the project, this may involve repairing individual stones, replacing severely damaged sections, rebuilding areas of masonry or restoring elements of a traditional building.
Signs Your Stonework May Need Attention
Cracked Masonry
Cracks within stonework can have a number of causes and should be assessed to determine whether further repair is required.
Deteriorating Stone
Weathering and prolonged exposure can gradually damage natural stone, particularly where water and moisture are able to penetrate the masonry.
Loose or Displaced Stone
Movement or deterioration can cause individual stones or sections of masonry to become loose or displaced.
Failed Mortar
Deteriorating pointing can leave masonry vulnerable to further weathering and may contribute to wider deterioration.
Previous Repairs
Older repairs may have been carried out using materials that are unsuitable for the original construction. These may require careful removal and replacement.
Our Structural Repair Process
1. Survey & Assessment
We survey the existing stonework and mortar before determining the appropriate approach.
2. Understanding the Problem
Where possible, we consider what has caused the damage rather than simply treating the visible defect.
3. Selecting Suitable Materials
The appropriate stone and mortar will depend on the existing construction and the nature of the repair.
4. Carrying Out the Repair
Our team carefully carries out the necessary repair work, aiming to retain existing stone wherever practical.
5. Finishing the Stonework
Repairs are finished with consideration for the appearance and character of the surrounding masonry.
Restoring Traditional Stone Buildings
Older stone buildings often require sympathetic repair to preserve their character. Rather than automatically replacing large sections of original masonry, we consider whether existing stone can be retained and repaired.
The materials and techniques used can also be important. Traditional buildings may have been constructed using lime mortar and other materials that behave differently from modern construction.
Repairing Rather Than Replacing
Where existing stone can be retained and repaired, this may help preserve more of the original fabric and character of a building. However, where stone has deteriorated beyond practical repair, replacement may be necessary. We assess each situation individually and recommend an appropriate solution.
Frequently Asked Questions
What are the signs that stonework needs repairing?
Cracking, loose or displaced stone, deteriorating mortar, significant weathering and damaged sections of masonry can all indicate that repairs may be required. An assessment can help establish the extent and cause of the problem.
Can damaged stone be repaired rather than replaced?
In some cases, yes. The appropriate solution depends on the type and extent of damage. Where practical, retaining and repairing existing stone can help preserve the character of a traditional building.
Do you restore traditional stone buildings?
Yes. Clarke Heavey undertakes repair and restoration work on traditional stone properties, taking the existing materials, construction and condition into consideration.
Can you repair structural cracks in stonework?
Structural cracks require careful assessment because the cause and severity can vary considerably. Clarke Heavey can assess the masonry and, where appropriate, undertake the required repair work. Some projects may also require input from a structural engineer.
Do you replace damaged stone?
Where an individual stone or section of masonry is beyond practical repair, replacement may be appropriate. We consider the surrounding masonry when selecting suitable replacement materials.
Do you also carry out Lime Repointing?
Yes. Lime repointing is one of our specialist services and can form part of a wider stone repair or restoration project where appropriate.
