Keep weather out of weakened joints
Failed mortar cut out
We remove loose material to a sound depth instead of covering weak joints.
Exposed areas inspected
The cap and upper brickwork are checked for defects linked to water entry.
Scope based on condition
We assess how much sound masonry remains before agreeing the repointing.
Renew mortar before bricks work loose
Mortar joints take the brunt of rain, frost and wind around an exposed chimney. Once they crack, erode or fall away, water can enter the masonry and otherwise serviceable bricks may begin to loosen. We complete chimney repointing in Newtownabbey by removing failed mortar to a sound depth, preparing the joints and applying suitable new mortar. The finish is formed to resist weather rather than simply covering the face of the old joint. We also inspect the exposed masonry and chimney cap so related defects can be identified while access is available.
Preserve a stack that remains serviceable
Repointing is most useful when the chimney structure and bricks remain suitable for retention. The amount of failed mortar, chimney height, access and condition of the masonry all shape the job. We inspect these factors before explaining the extent of work and arranging a suitable platform. Smaller masonry faces can also be repointed where joints have deteriorated. If bricks or upper sections have become unstable, we'll distinguish the repair from work requiring rebuilding. You receive photographs and a straightforward explanation, not a vague instruction to take our word for it.
Frequently asked questions
How can I tell if my chimney needs repointing?
Common signs include cracked, recessed or missing mortar between bricks. Loose fragments may also appear around the roof or ground below. A close inspection is needed because upper joints can be difficult to judge safely from ground level.
Can repointing stop further chimney weathering?
Renewing failed joints helps reduce moisture entry and protects serviceable brickwork from further exposure. It won't correct unstable or badly damaged masonry, so we check the stack first and explain if rebuilding is also required.
Do you inspect the chimney cap at the same time?
Yes. The cap and upper masonry sit in the most exposed part of the stack, so we inspect them alongside the joints. If we find cracking or another defect, we'll explain it separately before adding any work.
