Chimney Cap Installation in Newmarket
A chimney cap is the cheapest insurance on the entire structure. It stops rain going straight down an open flue, keeps raccoons, squirrels and starlings out, blocks embers from landing on the roof, and — with the right design — fixes downdraft that no amount of firewood technique will solve.

What we do
Chimney Cap Installation in Newmarket — how it works
We install stainless steel, never galvanised. Galvanised caps rust out in five to eight Ontario winters and the rust runs down the brick face, staining it permanently. A properly sized stainless cap with a spark screen and a bolt-on band will outlive the roof under it.
Signs you need this service
- No cap at all — you can see daylight down the flue
- A rusted, dented or partly detached cap
- Rain audibly dripping into the firebox
- Animals, birds or nesting material in the chimney
- Wind blowing smoke back into the room on gusty days
- Debris and leaves accumulating on the smoke shelf
What's included
- 304 or 316 stainless steel construction
- Spark arrestor / animal screen
- Correct sizing to the flue, not the brick
- Crown and top-course condition photos
- Lifetime cap warranty on premium models
Our process
Step by step, start to finish
- Step 1
Measure the flue
Interior dimensions, tile projection and number of flues — caps are not one size fits all.
- Step 2
Match the cap to the problem
Standard, multi-flue, top-sealing damper or a wind-directional draft-correcting cap.
- Step 3
Inspect the crown
We check the crown at the same time, because a cap on a failed crown solves half the problem.
- Step 4
Secure installation
Bolt-on or band-clamped stainless, never silicone-only.
- Step 5
Draft verification
For downdraft complaints we take a reading before and after.

Local knowledge
What this looks like around Newmarket
Hilltop King City and open-field East Gwillimbury lots get wind that tumbles over the roofline and pushes down the flue. A standard flat cap does nothing for this — a wind-directional or draft-correcting cap does, and it is a far cheaper fix than raising the chimney.
Around Musselman's Lake, Keswick and the wooded Aurora estates, animal entry is the number one cap call we take. Raccoon removal plus a heavy-gauge screened cap in one visit is the standard solution.
FAQs
Questions homeowners ask us
How much does a chimney cap cost in Newmarket?
$180 to $320 installed for a standard single-flue stainless cap. Multi-flue caps are custom fabricated to the crown and run $450 to $900. Top-sealing damper caps and draft-correcting caps sit in between.
Do I really need a chimney cap?
Yes. An uncapped flue takes rain directly onto the smoke shelf and damper, rusting the damper and saturating the masonry from the inside, and it is an open invitation to animals. It is the highest value-per-dollar item on a chimney.
Will a cap stop my fireplace from smoking?
It will if the cause is downdraft from wind or a short chimney, which a wind-directional cap addresses directly. If the cause is negative pressure inside a tight house or an undersized flue, the fix is different — that is why we take a draft reading first.
Stainless or galvanised?
Stainless, always. Galvanised is cheaper up front and rusts out within a decade in Ontario, staining the brick as it goes. We do not install galvanised caps.
