Sound joints without hiding bigger defects
Failed mortar removed
We cut out unsound material instead of covering it with a thin patch.
Masonry condition checked
We look for damaged bricks, stone and movement before repointing.
Finish chosen carefully
We consider mortar compatibility, joint profile and curing weather.
Replace mortar that's letting water in
Chimney joints face more weather than most masonry on a property. Once mortar becomes cracked, hollow or washed out, moisture can settle in the stack and worsen during freezing conditions. That may lead to loose bricks or stone, internal damp and a much larger repair later. We remove unsound mortar to a suitable depth, clean and prepare the joints, then install replacement mortar with an appropriate finish. Our three-year bricklaying apprenticeship underpins this careful approach. The aim isn't to smear fresh mortar over the face, but to renew failed joints so they can do their job.
Check the masonry as well as the joints
Repointing only works when the stack is stable enough and its masonry remains serviceable. We inspect bricks or stone for cracking, spalling and movement because new joints won't rescue units that are already badly damaged. Mortar compatibility, joint profile and curing conditions all affect durability and appearance. Where movement or widespread deterioration is present, rebuilding or masonry replacement may be needed instead. For chimney repointing in Kendal, we define the limit of sound work before removing mortar.
Frequently asked questions
How can I tell if my chimney needs repointing?
Look for gaps, crumbling mortar, deep weathered joints or loose fragments around the stack. Damp near the chimney can also be related, although flashing and masonry defects may cause similar signs. We inspect the full stack before confirming the repair.
Can repointing stop a chimney leak?
It can stop water entering through failed mortar joints when those joints are the true cause and the masonry is sound. It won't fix split leadwork, cracked flaunching or damaged bricks, so we check those details before relying on repointing alone.
Why does the replacement mortar need to be compatible?
Mortar has to work with the existing masonry and exposure. An unsuitable mix can behave too differently, trap moisture or leave a poor finish. We consider the stack material, joint condition and curing weather when planning the work.
