Lime Mortar Repointing
Mortar is sacrificial, not structural. It's designed to take water in and out and protect the masonry around it. Modern hard cement cracks historic brick and stone. We test, match, and repoint with soft, breathable lime mortars built for your building.
On a historic building the mortar is sacrificial, not structural. The stones or bricks carry the load; the mortar is designed to be the softer, breathable layer that takes water in and lets it back out, protecting the masonry around it. That's why putting a hard, modern cement on old masonry does real damage: the brick or stone becomes the weak point instead, and it spalls and cracks.
There are many lime mortars, with different colors, densities, and compositions, and the only way to know the right one is to test and assess the existing mortar first. We analyze what's there, match the color, density, and joint profile, carefully remove the failed mortar, and repoint with a soft, breathable lime mix matched to your building.

Lime Mortar Repointing FAQs
Why use lime mortar instead of standard cement?
Old masonry was built to flex and breathe with a soft, sacrificial mortar. A hard modern cement won't move or let water out, so the brick or stone becomes the sacrificial element instead and starts to crack and spall. Lime mortar protects the masonry the way it was designed to be protected.
What is a mortar test and why does it matter?
It's an analysis of the existing mortar (its composition, color, density, and joint profile) so the replacement can be matched correctly. Mortars are not interchangeable; only a matched lime mix will perform and look right. Getting it wrong can quietly damage the wall for years.
How do I know if my masonry needs repointing?
Look for crumbling, receding, or cracked joints, gaps you can see light or feel a draft through, or bits of mortar collecting at the base of the wall. We confirm the condition during a free on-site evaluation.
