Chimney Repointing
Chimneys are exposed to some of the harshest weathering on any property, making them one of the first areas where mortar failure becomes visible. At S.J. Lewis Repointing Services, we provide expert chimney repointing across Oxfordshire, restoring structural stability, preventing water ingress, and protecting both modern and heritage homes from long‑term damage. Our work ensures your chimney remains safe, secure, and built to withstand decades of weather.
🧱 Specialist Chimney Repointing for All Property Types
Chimneys deteriorate faster than other masonry due to constant exposure to wind, rain, frost, and heat.
We carefully remove failing mortar and repoint using the correct materials for your property — whether that’s traditional lime mortar for heritage homes or cement mortar for modern construction.
Our chimney repointing covers:
- Brick chimneys
- Stone chimneys
- Listed and period property chimneys
- Modern homes and extensions
- Boundary and garden chimneys
🌿 Traditional Lime Mortar for Heritage Chimneys
For older or listed buildings, using the correct lime mortar is essential.
Lime allows the chimney to breathe, preventing trapped moisture, frost damage, and brick or stone decay. We match the mortar’s colour, texture, and strength to the original construction, ensuring a seamless, heritage‑appropriate finish.
🛡️ Protecting Your Home from Water & Structural Damage
A failing chimney can cause serious issues if left untreated.
Professional chimney repointing helps to:
- Prevent water ingress and internal damp
- Stop brick and stone erosion
- Improve structural stability
- Reduce the risk of chimney movement or collapse
- Protect rooflines, leadwork, and surrounding masonry
- Extend the lifespan of the entire chimney stack
Because chimneys sit above the roofline, even small defects can quickly become major problems — timely repointing is essential.
🏛️ Conservation‑Led Techniques for Listed Buildings
Listed and historic chimneys require a careful, methodical approach.
We follow conservation best practice, ensuring all repointing respects original materials, joint profiles, and architectural detailing. Every joint is hand‑tooled for accuracy, delivering a finish that blends seamlessly with the building’s historic fabric.
