The chimney crown is the concrete cap at the very top of your chimney in Dickson Hill, Markham. 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 Dickson Hill, Markham

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.

4.9 average from 743 verified customer reviews
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.

Camera scan caught a cracked tile
Previous company swept and said everything was fine. Diamond ran a camera and showed me a cracked liner tile on screen. Glad I got the second opinion.
Marta S. - Mississauga - 2025-11-30
Fast after a smoke back-up
Smoke came into the living room on a Sunday evening. They were here the next morning, found a nest, cleared it, and tested the draft before leaving.
