Chimney Repair in Newmarket
Almost every chimney repair in Ontario traces back to one thing: water. Rain and snowmelt enter through a cracked crown, a missing cap or open mortar joints, soak into the masonry, then freeze. Each freeze-thaw cycle expands and pushes the brick face off. By the time you can see the damage from the driveway, water has usually been inside the stack for several seasons.

What we do
Chimney Repair in Newmarket — how it works
We repair rather than replace whenever the structure allows it. A crown reseal, a proper stainless cap and repointing the top courses will often buy fifteen more years for a fraction of what a rebuild costs. When a rebuild genuinely is the right call, we show you the photos that prove it.
Signs you need this service
- Brick faces flaking, popping or crumbling (spalling)
- Mortar joints you can scrape out with a key
- A cracked, sloped-wrong or missing crown
- Rust stains, a damaged cap, or no cap at all
- Water stains on the ceiling or wall beside the chimney
- White chalky staining (efflorescence) on the exterior brick
- A leaning stack or visible gap at the roofline
What's included
- Full photographic assessment of the stack
- Colour and texture matched mortar on heritage brick
- Waterproof breathable sealer option on repointed masonry
- Stainless caps, never galvanised
- Debris removal and site cleanup

Roof-level assessment

- Step 3
Repair-vs-rebuild call
A written recommendation with the photos attached, not a verbal upsell.
- Step 4
Scheduled in curing weather
Mortar and crown work is booked April to October wherever the damage allows waiting.
- Step 5
Warranty and report
Workmanship warranty in writing plus before-and-after photos.

Local knowledge
What this looks like around Newmarket
Bradford and the Holland Marsh edge produce the worst moisture damage on our map — persistent damp and fog mean spalling runs deeper than it looks. Georgina's lakefront is a close second because of wind-driven rain off Lake Simcoe.
In downtown Newmarket and the Aurora village core, heritage brick needs a softer lime-based mortar. Using modern Portland mix on soft century brick accelerates the damage, and it is the single most common bad repair we are called to undo.
FAQs
Questions homeowners ask us
Can chimney repair be done in winter?
Emergency work such as a temporary cap, a tarp or an interior seal can be done any time. Mortar and crown work needs consistent temperatures above freezing to cure to strength, so we schedule structural masonry between April and October.
How do I know if I need repair or a full rebuild?
If the damage is confined to the top few courses and the crown, repair is nearly always correct. If the stack is leaning, the brick is spalled below the roofline, or the flue tiles have shifted, a rebuild from the roofline up is the honest answer. We show the photos either way.
Will insurance cover chimney repair?
Sudden damage — a lightning strike, a chimney fire, a wind event — is often covered. Gradual freeze-thaw deterioration is normally classed as maintenance and is not. Our photo report is written so a claims adjuster can read it.
How long does chimney repair take?
A crown reseal or cap install is a same-day visit. Repointing the top courses is one to two days. A rebuild above the roofline typically runs two to four days depending on weather and height.
