Chimney Repairs in Crowthorne

Chimney Repointing & Flaunching in Crowthorne

Brickwork that stays damp in the shade of the pines loses its mortar faster than a stack in the open, and moss growing in the joints speeds that up. Repointing clears out the soft, mossy mortar and fills the joints again, so the stack can dry out properly between showers.

Flaunching under the trees often has moss growing over it, which hides cracks until water is already getting into the top of the stack. We clear it back to check it, and renew it where it has cracked so the pots sit firm.

Chimney Leadwork & Lead Flashing in Crowthorne

The back gutter is the part of a chimney's leadwork that suffers most in Crowthorne. It sits behind the stack, catches everything that slides down the roof, and soon fills with needles, so rain overflows it and runs into the roof. Clearing it is the start, and if the lead underneath has split, that piece is repaired or renewed. Where the leadwork is worn all round, a new set is cut, dressed to the stack and fixed into the brick joints.

These are the parts of the leadwork around a chimney stack.

Apron Flashing

Covers the front of the stack and laps down onto the tiles below.

Stepped Flashing

Soakers

Lie under the tiles beside the stack, turned up against the brickwork.

Back Gutter

The uphill lead behind the stack, which needles and leaves fill most quickly.

Cover Flashing

Fixed into the brickwork and dressed down over the soakers.
