Peak Roofing and Building carries out all types of chimney repair work throughout Castleknock, from minor repointing of crumbling mortar joints to full chimney stack rebuilds. Chimney problems are among the most common causes of roof leaks in Castleknock: deteriorated pointing allows water to penetrate the stack, failed lead flashing creates a direct leak path, and cracked chimney pots allow water entry from above. We can diagnose and repair all of these on a single visit.

In Castleknock, chimney issues are particularly prevalent on properties built before 1970, where original lime mortar has softened and eroded over decades of weather exposure. Coastal areas close to Castleknock see mortar erosion accelerated by salt air. We carry out a free chimney inspection as part of every roof survey, checking the stack condition, lead flashing, pot condition and internal liner where accessible.

Areas we cover in Castleknock: Castleknock Road, Carpenterstown Road, Auburn Avenue, Beechfield estate, Elmpark, Laurel Lodge and Carton Wood

"James and the team have done two different jobs for us. The first was to re-felt our roof and fix the flashing around the chimney and clear gutters which cleared up 2 substantial leaks that had been causing damage. He kept us updated with videos of the work throughout the day to show work complete and progress."
