A fireplace and chimney specialist, not a general contractor with a brush
Oshawa Fireplaces & Chimney has spent 15 years on one narrow problem: keeping the flues, fireboxes and vents in Durham Region homes safe, dry and drawing properly. Sweeping, camera inspection, WETT certification, crown and cap work, repointing and rebuilds, stainless liners, gas fireplace diagnosis and repair, insert installs and venting — that is the whole list, and it is the reason we are faster and more accurate on it than a general HVAC outfit that sweeps chimneys on the side.
Oshawa is a genuinely mixed town for this work. Downtown and McLaughlin hold pre-1940 brick with original masonry stacks, many unlined and later converted to gas. Samac, Windfields and Eastdale are full of 1980s and 1990s zero-clearance fireplaces now well past the age where the pilot assembly, thermopile and glass gasket all fail together. Kedron and Taunton are sealed, direct-vented and airtight, which brings its own problem: negative pressure that pulls smoke into the room.
We cover Durham Region end to end — Oshawa, Whitby, Brooklin, Ajax, Pickering, Courtice, Bowmanville, Newcastle, Clarington, Uxbridge, Port Perry, Ashburn and the rural concessions between them. Each behaves differently. The Bowmanville and Port Whitby lakefront rusts caps and cracks crowns years early. North Durham's ridge properties fight downdraft on exposed hilltop lots. Rural Uxbridge and Scugog homes burn genuine cordwood volume and need a sweep every single season.
Every visit follows the same order: inspect and measure first, quote second, work third. We take a draft reading, scope the flue on camera, check clearances to combustibles and photograph what we find before a price is written. That sequence is why our repairs hold, and why we can tell you honestly when the answer is "nothing, it is fine, see you next year."

Seasonal demand
What breaks, and when, in a Durham Region home
Booking the right work in the right month is the cheapest maintenance decision you will make all year.
October to March — the burning season
This is when the north Durham ridge gets cold and Oshawa fireplaces stop being decoration. The calls we run are no-ignition gas fireplaces, snow-blocked sidewall terminations in Brooklin and Port Perry, smoke roll-out in tight new builds, and chimney fires in flues that were never swept. Book the sweep in September and you skip the entire queue.
April to September — the masonry season
Warm, dry months are the only correct window for crown rebuilds, repointing, flashing and liner installs, because mortar has to cure above freezing to reach full strength. Summer pricing is also better and lead times are days rather than weeks. If your inspection flagged masonry work, this is when to do it.
- Sweep before the first fire, not after the smoke alarm goes off
- Cap and crown checks after every freeze-thaw winter
- Gas fireplace service every second year, glass gasket at year seven
- WETT report refreshed whenever you change insurer or sell

FAQ
Chimney, fireplace, crown, cap and liner questions we get every week
Straight answers on cost, timing, certification and what to do when smoke comes into the room.
How much does a chimney sweep cost in Oshawa?
A standard chimney sweep with a Level 1 inspection in Oshawa runs $180 to $340 for a single open masonry fireplace or wood insert. Tall three-storey Windfields and Taunton elevations that need roof-harness access, or a second flue on the same visit, sit at the upper end. The price is confirmed in writing before we start and includes the written safety report.
How often should a Oshawa chimney be swept and inspected?
Once a year for any wood-burning fireplace, insert or stove burned through the season, and every two years minimum for a gas appliance vented through masonry. Oshawa sits high on the north Durham ridge and runs colder than downtown Oshawa, so local fireplaces burn more hours per winter — creosote builds up faster here than the general Ontario guidance assumes.
Why does my gas fireplace shut off after ten or fifteen minutes?
Nine times out of ten it is a weak thermopile, a dirty thermocouple or a pilot that is drifting off the sensor. The safety circuit reads the drop and closes the gas valve exactly as designed. It is usually a same-visit fix — we carry thermopiles, thermocouples, pilot assemblies and glass gaskets on the truck for the fireplace brands common in Durham Region.
What does chimney crown and cap repair cost?
A cap replacement is typically $180 to $450 installed depending on flue size and whether you need a single, multi-flue or draft-correcting cap. A crown reseal runs $350 to $700, and a full crown rebuild in concrete is $900 to $2,200. Fixing a hairline crown crack early is the single cheapest way to avoid a five-figure masonry rebuild later.
Do you provide WETT inspections for insurance in Oshawa?
Yes. WETT-certified inspections are one of our most requested services in Ajax, Clarington and rural King, where insurers routinely ask for documentation on any wood-burning appliance before they will bind or renew a policy. You receive a signed report you can send straight to your broker.
My chimney brick is flaking and the mortar is crumbling — is that urgent?
Spalling brick and washed-out mortar joints mean water is already inside the masonry. Ontario freeze-thaw cycles turn that water into pressure every night, and each cycle takes more brick with it. Repointing while the damage is in the top few courses costs a fraction of a rebuild from the roofline up, so yes — get it looked at this season, not next.
Does my chimney need a liner?
If your home was built before roughly 1950 and later converted to gas or oil, there is a real chance the flue is unlined or lined with clay tile that has cracked. That is the most common serious defect we find in downtown Oshawa and the Whitby village core. A stainless steel liner properly sized to the appliance resolves it and typically runs $2,200 to $4,800 installed.
Do you do emergency and same-week appointments?
Yes. Carbon monoxide alarms, gas odours, chimney fires, smoke backing into the room and no-heat calls jump the queue. Routine sweeps and inspections are usually booked within the same week outside the October-to-December rush — book September if you want your pick of dates.
Which fireplace brands do you service?
Napoleon, Valor, Regency, Continental, Marquis, Montigo, Heat & Glo, Majestic, Mendota, Pacific Energy, Osburn, Enviro and Kozy Heat, plus most builder-grade zero-clearance units installed across Durham Region subdivisions since the 1990s — regardless of who installed it.
Are you licensed and insured?
Every technician is WETT certified for solid fuel, holds a G2 or G1 gas licence, is TSSA registered, and works under $2M liability coverage. Everyone entering your home is background checked. Ask any contractor for those four things before they open a firebox.
Can you fix a fireplace that smells or smokes into the room?
Yes, and it is rarely the fire's fault. Smoke roll-out comes from negative pressure in a tightly sealed modern house, an undersized or blocked flue, a cap that is causing downdraft, or a smoke chamber that was parged badly when it was built. We diagnose the cause with a draft reading rather than guessing, then quote the actual fix.
What do I get after the visit?
A photo-documented written report: flue condition, creosote grade, liner status, crown and cap condition, draft readings, clearances to combustibles, and anything to monitor before next season. It is written for a homeowner, not for another tradesperson, and it is what your insurer will accept.
