Chimney Repair in Markham
Century brick on Unionville's Main Street and 25-year-old stacks in Berczy have different problems and need different fixes. We do both, with a 2-year workmanship warranty on every job.
Markham's chimneys were built a century apart.
Walk from Unionville's Main Street into Berczy and you cross a hundred years of construction in ten minutes. The village cores of Unionville and Markham Village carry 19th-century brick that needs soft, compatible mortar and a patient hand. The subdivisions that built modern Markham, from Milliken up through Cornell, Greensborough and Wismer, carry production-era chimneys whose thin crowns and fast mortar are failing right on schedule at 25 to 30 years.
We work both ends of that spectrum every week. It's the same crew behind our Toronto chimney repair and rebuild service, and when the job runs past the chimney, our Markham masonry contractor page covers the rest.

Which Markham is your chimney from?
The diagnosis starts with the decade your street was built.
Unionville & Markham Village
Original clay brick with lime-based mortar. The enemy here is the wrong repair: hard modern mortar traps moisture and destroys brick that survived a century on its own.
- Compatible soft-mortar repointing
- Reclaimed brick sourcing for rebuild courses
- Joint profiles matched to the original mason's
Berczy, Cornell, Wismer & Greensborough
Production-built chimneys with thin crowns and speed-mixed mortar. They fail younger than they should, and the fix is rebuilding those details to the spec they should have had.
- Full-thickness poured crowns with a proper wash
- Repointing before loose brick makes it a rebuild
- Rain caps on flues that never got one
Signs it's time to call
Any of these on a Markham roofline is worth a free inspection.
Mortar dust on the roof
Grit collecting in valleys or gutters below the chimney means joints are actively eroding. Cheap to fix now, expensive to ignore.
Hairline cracks in the crown
Every crack is a water channel, and one winter of freeze-thaw widens it. Crown repairs are the best-value job in chimney work.
Gaps at the flashing line
Staining on interior ceilings near the chimney usually traces back to failed flashing where brick meets shingle. We repair both sides of that joint.
