The most common reasons for re pointing an old building are -
The property has been pointed in the past with the wrong hard material (such as cement) which is trapping moisture inside the wall and allowing damp to show internally. This can also cause spalling which is a consequence of having pointing mortar harder than the brick or stone forcing any trapped moisture to blow the face of the brick or stone off rather than sacrificing the mortar joints.
The original lime mortar has run it's course and needs replacing. perhaps holes are starting to appear due to joints crumbling away and falling out therefore allowing the wind to blow rain water inside the wall.
Simply Aesthetics, the building is looking tired and perhaps the mortar has weathered to the point where you can no longer distinguish the mortar joints from the stone, brick or flint and could do with tidying up.
Mortar bees or masonry bees are another common reason for customers requesting to have re-pointing done, they are a species of bee that like to burrow into soft and weathered mortar joints in brick or stone walls and will then use the crevices inside the walls.
We would first start by covering near by objects and plants with plastic ensuring mess is minimized for the duration of the job. We would then begin raking out the existing mortar joints back to a suitable depth and at the same time removing any faceless or tired looking stone and bricks. The wall and joints will then be prepped and cleaned ready for the new Lime Mortar to be applied. Any new or replacement bricks and stone you request will be reclaimed and sourced locally to ensure an exact match.
