Internal & External Wall Repointing
Walls — both inside and outside your property — play a crucial role in protecting the structure, managing moisture, and preserving the building’s overall appearance. At S.J. Lewis Repointing Services, we provide expert internal and external wall repointing across Oxfordshire, restoring brick, stone, and lime‑based walls with precision and care. Whether your property is modern, period, or listed, our workmanship ensures long‑lasting protection and a clean, authentic finish.
🧱 External Wall Repointing for Long‑Term Protection
External walls face constant exposure to rain, frost, wind, and temperature changes.
Over time, mortar joints deteriorate, allowing water to penetrate and cause structural issues.
Our external wall repointing:
- Strengthens weakened or eroded joints
- Prevents water ingress and damp
- Protects brick and stone from weather damage
- Restores a clean, crisp, uniform appearance
- Extends the lifespan of the building’s exterior
We use the correct mortar for your property — lime for heritage buildings and cement for modern construction — ensuring full compatibility and long‑term durability.
🏠 Internal Wall Repointing for Breathability & Stability
Internal walls, especially in older properties, often suffer from trapped moisture, failed cement repairs, or crumbling mortar.
We carefully remove defective mortar and repoint using breathable, traditional materials that allow the building to function as originally intended.
Internal repointing helps to:
- Improve breathability and reduce damp
- Stabilise ageing brick or stonework
- Restore original character and detailing
- Prepare walls for plastering, limewash, or decorative finishes
- Prevent long‑term structural issues
This is particularly important in cottages, cellars, barns, and listed buildings where moisture management is essential.
🌿 Traditional Lime Mortar for Heritage Walls
For period and listed properties, using the correct lime mortar is vital.
We match the mortar’s colour, texture, and strength to the original construction, ensuring a seamless, heritage‑appropriate finish.
Lime mortar repointing:
- Allows moisture to evaporate naturally
- Prevents cracking and stone or brick decay
- Maintains the building’s historic integrity
- Supports long‑term structural health
🛡️ Protecting Your Walls Inside & Out
Professional wall repointing provides essential protection by:
- Preventing damp and moisture penetration
- Strengthening the building’s structure
- Improving energy efficiency and breathability
- Enhancing appearance and kerb appeal
- Extending the lifespan of brick and stonework
Whether it’s a full elevation, a garden wall, a cellar, or an internal feature wall, our approach ensures every joint is restored with accuracy and care.
