Chimney Crown Repair in Greensborough, Markham
Professional chimney crown repair in Greensborough, Markham — 24 hour response, licensed & insured.
The chimney crown is the concrete cap at the very top of your chimney in Greensborough, 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 Greensborough, 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.
