Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Led by Warren Tilsley, our Chimney Sweep team has built its reputation in this area on one thing: showing homeowners footage of their flue before we recommend a single repair. No one here guesses. That matters in Ontario, where original clay-tile chimneys hide problems a visual look-over will miss every time.
Why Limestone Chimney Sweep Is Ontario’s Preferred Chimney Sweep Company
Ontario homeowners deal with two realities most coastal sweep companies never see. First, the Santa Ana wind season drops eucalyptus bark, palm fronds, and grit into caps and screens, leaving spark arrestors choked by the time winter cold snaps hit. Second, most of the city’s housing stock is original mid-century tract: chimneys built in the 1950s-70s boom, many unlined or clay-tile lined, many unused for years at a stretch. We know exactly what that combination produces when a fireplace suddenly gets fired up again.
Our reputation in Ontario comes from repair readiness. When we find cracked flue tiles, rusted dampers, or third-degree creosote, we carry the materials to address it, not a brochure for a second visit two weeks out. We stock HeatShield, Gelco, Olympia Chimney, and Famco components so the fix can start the same day. Ontario customers regularly tell us that’s the difference between a sweep company and a chimney contractor. Warren Tilsley built Limestone to be the latter.

Chimney Services in Ontario
Chimney Services in Ontario means a lot more than running a brush. The job here starts with the question of whether your chimney is even sound enough to burn safely. In a 1963 ranch off Grove Avenue in 91762, the flue may have never been inspected since the day it was mortared. We treat every Ontario appointment as a safety visit, not a seasonal chore, and we document everything with camera footage.
Level 1 Inspection
A Level 1 inspection is the standard check when your chimney is in regular use and nothing has changed. We verify the flue is clear, the damper opens and closes, and there’s no visible deterioration in accessible areas. In Ontario, where many homes fire up their fireplaces only a few months each year, this is the baseline before any sweeping begins.
Level 2 Inspection
A Level 2 inspection uses a camera to scan the full flue interior, including sections you cannot see from the firebox or roof. We recommend this for any Ontario home built before 1980 that hasn’t had one, because clay tiles crack invisibly and animal nests hide in the middle sections. It is also required by most real estate transactions and after any chimney fire or major weather event.

Chimney Sweep Certified in Ontario
Chimney Sweep Certified in Ontario means our sweeps are trained to clean without damaging aging masonry, and to recognize when a flue isn’t burning safely. We remove creosote, soot, and debris from fireboxes, smoke chambers, dampers, and flue liners, then document the result. For Ontario’s older stacks, this is measured work; aggressive brushing on cracked clay tile turns a small problem into a liner replacement.
Annual Sweep
Even if you only burn a dozen fires a season in Ontario, an annual sweep is the cheapest insurance against a flue fire. First-degree creosote left through an idle summer can harden into third-degree glaze by the next winter, especially after Santa Ana dust gets baked into warm flue walls. A standard annual sweep in Ontario typically runs $189 – $289 with a Level 1 inspection.
Creosote Removal
Glazed creosote is the stubborn, tar-like buildup that comes from burning unseasoned wood or running fires too cool. In Ontario, we see it form in chimneys that sat dormant for years, then got pushed hard during a cold snap. Removal runs higher, $329 – $389 and up depending on the section count, because it requires rotary tools and chemical treatment, not just brushes.
Trusted Brands We Service in Ontario
We work with a curated set of professional-grade components because Ontario’s older chimneys need repairs that hold up to real heat. HeatShield allows us to restore a damaged flue from the inside without a full tear-out, which matters when you’ve got a 60-year-old stack and a stucco roofline you don’t want opened. Olympia Chimney and Famco supply us with caps, dampers, and spark arrestors sized for the area’s common masonry fireplaces. We keep components on hand for Ontario jobs, which shortens turnaround when a cap has rusted through or a damper has seized.
This stock also lets us fix what we find in a single visit. Not every sweep company in Ontario can say that. Most have to order parts and come back. We’d rather do the job once.

AfterCommon Chimney Sweep Problems We See in Ontario Homes
- Blocked spark arrestors from Santa Ana wind debris. Eucalyptus bark, palm fibers, and grit from the fall winds collect in the cap mesh and choke airflow, which pushes smoke back into the living room. Ontario homeowners often assume creosote is the culprit, but the camera usually shows a clogged screen instead.
- Cracked clay flue tiles in original 1950s-70s chimneys. Clay tiles crack from thermal shock after decades of disuse followed by sudden hot fires. A cracked tile can let heat and gases reach framing, and you won’t know without a Level 2 camera inspection.
- Rusted dampers at the throat of the firebox. Cold rainy winters and long idle stretches cause dampers to rust in place, often in the closed position. Homeowners then struggle to open them or smell smoke backing into the hallway.
- Animal nests in unused flues. Squirrels and birds get through damaged caps or missing screens and build in the smoke chamber. We find this regularly in Ontario homes that sat vacant or used only seasonally. The nest has to come out before any fire, because packed debris burns out of control once ignited.

FAQs About Chimney Sweep in Ontario
Spring smoking complaints in Ontario usually trace to a blocked spark arrestor or cap, not creosote. Santa Ana winds from late fall through early spring pack the cap mesh with eucalyptus bark, palm fibers, and grit. By spring, the cap is choked enough to push smoke back into the room. The fix is cleaning the cap and screen, sometimes replacing a rusted spark arrestor, and we show you the blockage on camera before doing anything. Call (855) 341-5439 and we’ll diagnose it the same day we’re in your area.
Yes, if the flue is original and has never had a camera inspection. A Level 2 inspection is non-negotiable before the first sweep of an older Ontario chimney because clay tiles can crack invisibly and you won’t know until heat reaches the framing. For subsequent sweeps, a Level 1 inspection is usually sufficient if nothing has changed and you’ve been burning consistently. We won’t recommend more than you need; we’ll show you the footage and let you judge.
Third-degree creosote looks like shiny black tar hardened onto the flue walls, and it won’t brush off with a standard chimney sweep. It forms when earlier creosote deposits bake in repeated heating cycles. In Ontario, we see it after a winter of burning unseasoned wood or running fires too cool. Only a camera inspection can confirm the stage, and removal requires rotary tools and often a chemical treatment. If your chimney smells like asphalt, call (855) 341-5439 to have it looked at before your next fire.
Newer infill homes in 91764 often have chimneys that were installed to code but rarely used, and the first issue we find is rusted dampers and damaged caps from disuse plus Santa Ana moisture. The venting is usually structurally sound, but the hardware corrodes faster than anyone expects. We replace dampers and caps with Famco or Olympia Chimney components, and we’ll show you the old part before we swap it out. Free estimates at (855) 341-5439.
Animals get in through damaged or missing chimney caps, and an unused flue is an inviting, wind-protected cavity. Squirrels and birds build in the smoke chamber during spring, and by fall the nest is packed with dried debris. Once you light a fire, that nest burns hot and fast, which is how chimney fires start in otherwise clean flues. A capped chimney with intact screening prevents most of it, and an inspection catches what’s already there. Call (855) 341-5439 to schedule a camera check before you burn again.
