The chimney crown is the concrete cap at the very top of your chimney in Huron Heights-Leslie Valley, 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 Huron Heights-Leslie Valley, 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.

Post-fire inspection
Small flue fire in January. They inspected, documented the damage, and coordinated the report with my insurer without me chasing anyone.
Daniel K. - North York - 2026-05-02
Level 2 for a house sale
Recorded the whole flue on video for the buyer's agent. The chimney line item stopped being a negotiation point the same day.
Tom H. - Markham - 2026-04-03
Exceptional chimney inspection
Punctual, professional, and walked me through every step. The report came the same afternoon with clear photos of the crown cracks they found. No pressure to book the repair.
Sarah M. - Toronto - 2026-05-14
Raccoon eviction and cap fitted
Family of raccoons in the flue. They removed them humanely, cleaned everything, and fitted a stainless guard that has kept them out since.
