Flint restoration & lime repointing
Flint & Form restores older flint walls and repoints them in lime mortar. We clean existing flint, carefully remove unsuitable sand-and-cement pointing, and repoint so the wall looks renewed rather than newly built: cleaner and better defined, while keeping the age of the original flint.
When this is needed
- Weathered or stained external flint elevations
- Walls previously pointed in sand-and-cement
- Flintwork that has lost definition and needs sympathetic repointing
- Preparation of existing walls as part of a wider alteration or extension
How we approach it
Unsuitable pointing is removed with care so the flint face is not needlessly damaged. Surfaces are cleaned to reduce accumulated dirt and organic matter. The wall is then repointed in a lime mortar chosen to complement the existing masonry.
Lime mortar is appropriate for traditional flintwork. It works with the wall rather than locking it into a hard, inflexible joint the way dense cement pointing often does.
What you can expect
- Removal of inappropriate sand-and-cement pointing where required
- Cleaning of existing flint
- Repointing in lime mortar
- A crisper, clearer appearance that still reads as an older wall
Restoration questions
Why remove sand-and-cement pointing from flint walls?
Hard sand-and-cement was often used on older flint walls but is a poor long-term partner for traditional flintwork. It is dense and inflexible compared with lime. We remove it where it is unsuitable and repoint in lime.
Will restored flint look brand new?
No. The aim is an aged but crisp finish: renewed clarity and cleaner joints, not a wall that looks newly built.
Do you always use lime mortar for repointing?
For restoration of traditional flintwork, yes. We repoint in lime-based mortar suited to the wall. Product choice depends on the job; named products used on a specific site appear in that case study.
Can you estimate from photos?
Photos are enough for an initial view and to say which approach looks right. A firm quote usually needs clearer scope, and often a site visit for larger or more complex walls.
