Chimney Repair in Ajax
Ajax was built in a hurry — first for the wartime plant workers, then for everyone who followed — and its oldest chimneys have stood in the lake wind ever since. We repair and rebuild them, backed by a 2-year workmanship warranty.
Ajax’s first chimneys are as old as the town itself.
Ajax exists because of a munitions plant: the town grew out of the wartime works, and the workers’ houses that came with it still stand in the south end and around Pickering Village. Those 1940s brick homes are into their ninth decade, and their chimneys — short, stout and never far from Lake Ontario’s wind — are overdue almost by definition. The subdivisions that followed through Applecroft and Southwood are younger, but the shoreline gusts that funnel up from Duffins Bay don’t check the build date.
Our Durham crew — the same team on our Pickering masonry contractor page — covers Ajax top to bottom, and every chimney gets the standard we set on our Toronto chimney repair and rebuilds: honest diagnosis, matched materials, and the fix in writing.

When an Ajax chimney is asking for help
Between old brick and lake wind, these come up most.
Grit on the shingles below the stack
Sand and mortar crumbs washing onto the roof are the joints emptying themselves. On a wartime chimney that process started years before anyone noticed.
The stack hums or whistles in a south wind
Gaps big enough to sing are gaps big enough to soak. Wind noise from the chimney means open joints or a failed cap, and both invite the next storm inside.
Patch jobs that didn’t hold
A lot of Ajax chimneys wear smears of roofing tar or caulk from past quick fixes. If the leak came back, the problem was never the surface — it’s the crown, the flashing or the joints underneath.
