Case Study: Heritage Lime Repointing – Applicable to Burford (Project Completed in Kirtlington)
Overview
This case study highlights the level of heritage craftsmanship and lime‑mortar expertise we deliver for clients in Burford.
Although the project itself was completed in Kirtlington, the building’s age, materials, and conservation requirements are extremely similar to many period homes in Burford — particularly those along the High Street, Sheep Street, and the surrounding conservation areas.
The methods, standards, and finish shown here are exactly what we provide for Burford homeowners seeking a premium, conservation‑correct repointing service.
Property Background
- Location of project: Kirtlington
- Property type: Early‑20th‑century brick cottage
- Construction: Soft, handmade brickwork with original lime mortar
- Condition on arrival:
- Mortar significantly weathered
- Cement patch repairs restricting breathability
- Damp patches forming internally
- Frost‑damaged bricks on lower courses
- Cracking around window heads and exposed elevations
These issues are extremely common in Burford, where many properties rely on breathable lime mortar to manage moisture and prevent long‑term damage.
Issues Identified
During the survey, we found:
- Cement repairs trapping moisture
- Deep voids behind failed mortar
- Spalling on weather‑exposed elevations
- Inconsistent pointing from previous repairs
- Damp transfer into internal walls
These conditions closely mirror what we regularly see in Burford’s older brick and stone buildings.
Our Heritage Repointing Approach
We applied the same conservation‑led process we use for all Burford projects:
1. Removal of Cement Repairs
All cement was removed carefully by hand to protect the soft brickwork and restore breathability.
2. Joint Preparation
- Joints raked back to a consistent depth
- All dust and debris removed
- Brickwork lightly dampened to prevent rapid drying
3. Lime Mortar Selection
A breathable NHL 3.5 lime mortar was chosen to match the original fabric.
The colour and aggregate were blended to replicate the building’s historic appearance.
4. Application
- Mortar applied in controlled lifts
- Joints compacted for long‑term durability
- Finished with a traditional brushed texture to match the period style
5. Curing & Protection
- Regular misting to ensure proper curing
- Hessian protection used during colder nights
- Gentle clean‑down with no chemicals
This is the same heritage‑grade process we use for all Burford properties.
Results
- Breathability fully restored
- Damp issues reduced
- Frost damage prevented
- Authentic period appearance reinstated
- Cement removed and replaced with correct lime mortar
- A clean, uniform, heritage‑appropriate finish
This standard of work is exactly what Burford homeowners can expect when choosing a specialist heritage repointing service.
Why This Matters for Burford Clients
Even though this project was completed in Kirtlington, it is directly relevant to Burford because:
- The brick types are similar
- The age and construction methods match many Burford properties
- The issues (cement repairs, damp, spalling) are identical
- The heritage approach is universal across traditional buildings
- The lime‑mortar techniques are the same
This case study demonstrates the craftsmanship, care, and conservation‑correct methods we bring to every Burford project.
