Chimney Repointing & Repairs in Dublin

Sound Brickwork Up Top Means Dry Rooms Underneath

No part of a house is as exposed as its chimney stack. It stands clear of the roof on every side, so the mortar joints wash out first, the mortar collar holding the pots (the flaunching) cracks, and water starts to track down inside the brickwork. Repointing means raking the tired mortar out to a sound depth and filling the joints again with a mix that suits the brick, so the stack sheds rain instead of soaking it up.

It is the right call when you can see open joints, loose bricks near the top, or a damp patch on the chimney breast upstairs after heavy rain. Plenty of red-brick terraces share one stack between two houses, so on those we look at the whole stack and talk you through what sits on your side.

We set up safe access, then work from the top down: pots and flaunching first, then the upper courses, which we rebuild where the bricks have frost-damaged or shifted, then the pointing and the lead flashings where the stack meets the roof. You get a written quote listing each of those items before any work starts.
