The chimney crown is the concrete cap at the very top of your chimney in Bristol-London, Newmarket. It sheds water off the top of the masonry and away from the flue. When it cracks, water pours into every course of brick below it — and freeze-thaw does the rest.

Why chimney crown repair matters in Bristol-London, Newmarket

Top-Down Water Damage

A cracked crown is the source of almost every spalling-brick problem on GTA chimneys.

Cheap Fix Now, Expensive Fix Later

Resealing a crown is a $400–$800 job. Rebuilding a spalled chimney is $4,000+.

Overhang Matters

A proper crown overhangs the brick by 1–2" with a drip edge. Flush-poured crowns funnel water straight into the masonry.
