A stonemason is a skilled craftsperson who cuts, shapes, dresses and lays natural stone. Stonemasons work across a wide range of projects - from building new stone walls and extensions to carrying out sensitive restoration of historic buildings. For listed buildings and heritage properties, a specialist stonemason with experience of traditional lime mortars and period techniques is essential. The trade is not statutorily regulated but recognised bodies including the SPAB (Society for the Protection of Ancient Buildings) and the Guild of Master Craftsmen provide quality assurance for heritage work.
What they do
- Cut, dress and lay natural stone for walls, quoins, copings and plinths
- Build new stone boundary walls, garden features and retaining walls
- Apply stone cladding to new or existing structures
- Repoint stonework in lime mortar to match original specification
- Repair and restore carved stonework, tracery and decorative details
- Match stone type, colour and texture on extensions and repairs
- Rebuild and repair chimney stacks in natural stone
- Work with architects and conservation officers on listed building consent projects
- Source appropriate stone from quarries and reclaimed stone suppliers
When you need one
A stonemason is needed whenever natural stone is being laid, repaired or restored - particularly on heritage and listed building projects where traditional techniques are essential.

Qualifications to look for
SPAB membership or training indicates knowledge of traditional building techniques and appropriate repair materials including lime mortars and natural stone. Widely recognised by conservation officers and historic building owners.
The Craft Guild of Stonemasons represents traditional stone carvers and masons. Guild membership indicates a practitioner with recognised craft skills and commitment to traditional stonemasonry techniques.
Guild of Master Craftsmen membership provides vetting and a code of conduct. A CSCS card (Construction Skills Certification Scheme) is expected on all but the smallest domestic projects. NVQ Level 2 or 3 in Stonemasonry is the standard trade qualification.
How to find a reputable stonemason
Frequently asked questions
How do I find matching stone for a repair?
A heritage stone supplier or geologist can identify the stone type. Some quarries that supplied the original building stone still operate, or reclaimed stone merchants may have matching material. Your stonemason should be able to advise on sourcing before work begins.
Do I need lime mortar for stone repairs?
Yes. Hard cement mortar traps moisture in the stone, leading to spalling and long-term damage. Always use lime mortar matched to the original for any historic masonry repair. A specialist stonemason working on heritage buildings will understand the correct lime specification.
What qualifications should a stonemason have for listed building work?
Look for SPAB membership, Craft Guild of Stonemasons membership, or proven experience with Historic England approved projects. The stonemason should also demonstrate the ability to work with lime mortars and traditional techniques appropriate to the building's period.
