Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterChimney Cleaning in Ontario, CA
Chimney cleaning in Ontario, CA runs $149 to $279 for a standard sweep, with Level 2 camera inspections adding $89 to $199. Most Ontario homes built in the 1980s and 1990s have factory-built zero-clearance fireplaces now pushing 30 to 40 years old, well past their rated service life. The real problem in this city isn’t heavy use, it’s the opposite: SCAQMD no-burn days keep fireplaces idle for long stretches, and that’s exactly when debris, nesting animals, and refractory panel cracks go unnoticed. Call (980) 580-8641 and we’ll put a camera down your flue and show you what’s actually there.
Why Ontario Homes Are Different
Ontario’s residential explosion in the 1980s and 90s filled entire neighborhoods with tract homes built around prefabricated metal fireplace inserts, not true masonry chimneys. Those units left the factory with service ratings of roughly 20 to 30 years. A large share of Ontario’s fireplaces are now overdue for inspection or replacement, and most homeowners don’t know it because the fireplace still lights fine on the occasional permitted burn evening.
The city sits in the Inland Empire basin near the Cajon Pass corridor, which puts Ontario in the direct path of Santa Ana wind events. Those winds force palm fronds, debris, and particulates down chimney flues and create downdraft conditions that push smoke back into living spaces. During the long idle periods mandated by SCAQMD Spare-the-Air no-burn days, the same flues become prime nesting habitat for birds and insects. On the handful of burn-permitted winter evenings when cold finally justifies a fire, the entire city lights fireplaces simultaneously, and that’s precisely when local smoke-rollback calls and chimney fire reports spike. Long-idle prefab units with deteriorated panels or debris-packed flues fail exactly when you need them most.
Our Main Ontario Services
Two hearth problems dominate the call volume in Ontario: aging fireplace assemblies that no longer seal or draft correctly, and caps and crowns that have lost their battle with Santa Ana winds and Inland Empire sun.
Fireplace Services in Ontario
Ontario’s prefab fireplace inserts from the 80s and 90s share a common failure pattern: warped fireboxes, cracked refractory panels, and failed gas valves on units that sat idle through SCAQMD no-burn winters while moisture and corrosion did their work. We inspect the firebox, damper assembly, log set or burner, and surrounding chase. When panels are cracked or the firebox is warped, we don’t guess, we show you the camera footage. Fireplace Services in Ontario covers inspection, repair, and replacement of prefab and masonry fireplaces across the city.
Chimney Cap & Crown in Ontario
Santa Ana winds take a measurable toll on chimney caps in Ontario every year, loosening mounting brackets and tearing screens that keep birds and embers out. Crowns crack under Inland Empire sun exposure and let water into the masonry below. A missing or damaged cap is also an open invitation for nesting animals during the long no-burn idle periods. We inspect cap and crown condition on every visit as part of our standard camera-scan documentation. Chimney Cap & Crown in Ontario details replacement options and what we stock for Ontario’s common roof pitches.

BeforeAfterChimney Sweep in Ontario
Chimney sweep in Ontario typically costs $149 to $279 and takes about 60 to 90 minutes. What makes this city unique is the false sense of security created by SCAQMD no-burn days: homeowners assume low usage means low maintenance need, while in reality the long idle stretches give debris, nesting animals, and cracked refractory panels time to accumulate silently. Our chimney cleaning always includes the camera-scan inspection standard and the photo record required under Clause 4 of the Haven Standard, which we’ve run continuously since our founding in 2009. See Chimney Sweep for the full technical detail on our process.
Level 1 Inspection
Signs you need it
An annual Level 1 inspection is the bare-minimum check for an Ontario fireplace that sees normal use, meaning the occasional burn on a permitted evening; it confirms basic soundness when nothing has changed since the last sweep.
What it costs in Ontario
A Level 1 inspection in Ontario runs $89 to $149, included with any standard chimney cleaning we perform.
How we do it
We examine the readily accessible portions of the fireplace, flue, and exterior chimney structure with a flashlight and visible-light camera, then log findings against the NFPA 211 Level 1 checklist.
Level 2 Inspection
Signs you need it
Any Ontario home that has gone a full Spare-the-Air season without cleaning, changed fuel type, had a chimney fire, or is in a real estate transaction needs a Level 2 inspection.
What it costs in Ontario
A Level 2 inspection in Ontario runs $199 to $399 and includes our full camera-scan footage and photo documentation as standard, not as an add-on.
How we do it
We run a high-resolution camera the full length of the flue, through the smoke chamber, and into the firebox, plus accessible attic and crawlspace scans, then write up the condition report with photos attached.
Creosote Removal
Signs you need it
If you notice a shiny, tar-like residue inside the firebox or a strong campfire smell when you open the damper, you are looking at Class II or III creosote that needs mechanical removal.
What it costs in Ontario
Heavy creosote removal in Ontario adds $100 to $220 to a standard sweep, depending on the flue length and how thick the glaze has built up.
How we do it
We run rotary whips and chemical treatments to break down glassy creosote deposits, doing multiple passes where needed to get back to brick or metal.
Soot Removal
Signs you need it
A fine black powder that puffs into the room when you light a fire usually means loose soot built up inside the flue and smoke chamber from last permitted burn season.
What it costs in Ontario
Soot removal is included in our standard Ontario sweep at $149 to $279; a standalone soot cleaning without full sweep work runs on the low end of that range.
How we do it
We brush from the top down with properly sized nylon or poly brushes, then vacuum the firebox and smoke chamber with HEPA filtration so no dust re-enters your Ontario living room.
Annual Sweep
Signs you need it
If you’ve burned wood on more than a dozen permitted evenings in the past year, or you don’t know when the chimney was last cleaned, schedule an annual sweep now.
What it costs in Ontario
An annual fireplace sweep in Ontario runs $149 to $279, with the Level 1 inspection included at no extra charge.
How we do it
We sweep the full flue length, clean the smoke chamber, remove the damper plate where needed for cleaning, and leave you with a written report and photos of the finished flue.
What Chimney Sweep Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Standard chimney sweep | $149 - $279 |
| Level 1 inspection | $89 - $149 |
| Heavy creosote removal (add-on) | $100 - $220 |
How often should I have my chimney swept in Ontario?
At least once per burn season, even if SCAQMD no-burn days kept your fireplace dark for months. Debris can enter the flue during idle stretches, and a pre-season sweep confirms the unit is safe before the first permitted burn evening. Call (980) 580-8641 to schedule before the winter rush.
Does a no-burn season mean I can skip chimney cleaning?
No. Long idle periods invite birds, insects, and debris into Ontario flues, and a sudden burn-permitted evening can ignite whatever accumulated. The low usage only hides problems, it doesn’t prevent them. Call (980) 580-8641 for an exact quote, which is free and written.
Chimney Repair in Ontario
Chimney repair in Ontario runs from about $250 for minor mortar work up to $2,500 to $6,000 for full rebuilding. The failures we see most often here trace back to two local conditions: Santa Ana wind cycles that pressurize and loosen masonry joints, and Inland Empire sun that bakes the crown until it cracks and lets water through. We always photograph the failing area first and include that photo record in your written quote. See Chimney Repair for the full engineering detail.
Mortar Repointing
Signs you need it
Crumbling or recessed mortar joints, especially on the exposed top courses, signal that water has already started penetrating the chimney structure.
What it costs in Ontario
Mortar repointing in Ontario runs $250 to $800 per section, depending on how many courses need grinding and refilling.
How we do it
We grind out the old mortar to proper depth, pack fresh mortar matched to your existing color and strength, and tool the joints to shed water.
Spalling Brick Repair
Signs you need it
Brick faces that flake off, especially near the top of the chimney, mean water has entered the masonry and is freezing or causing salt expansion.
What it costs in Ontario
Spalling brick repair in Ontario ranges $450 to $1,200 for a typical chimney top, with full chimney rebuilding at $2,500 to $6,000 when the damage is widespread.
How we do it
We remove the damaged brick, cut and set replacement brick, then repoint and waterproof the surrounding courses so water cannot trap inside.
Chimney Waterproofing
Signs you need it
A dark, damp patch moving down your chimney interior or white efflorescence on the exterior brick means water is moving through the masonry rather than over it.
What it costs in Ontario
Chimney waterproofing in Ontario runs $300 to $600 for materials and application on an average-height chimney.
How we do it
We clean the masonry surface, repair damaged joints first, then apply a breathable siloxane-based water repellent that blocks liquid water while allowing vapor out.
Flashing Repair
Signs you need it
A water stain on the ceiling near your fireplace after rain usually traces to failed flashing where the chimney meets the roof, common in Ontario homes with 30-year-old roof penetrations.
What it costs in Ontario
Flashing repair in Ontario runs $350 to $800, with full replacement as high as $1,200 on multi-chimney homes or steep roof pitches.
How we do it
We pull the old flashing, inspect the roof deck underneath, install step flashing and counter-flashing with new sealant, then test with a water hose before we leave.
Chimney Rebuilding
Signs you need it
Leaning chimneys, masonry that sounds hollow when tapped, or visible gaps wider than a quarter between smoke and structure mean serious structural loss.
What it costs in Ontario
Full chimney rebuilding in Ontario costs $2,500 to $6,000, depending on height, access, and how much of the flue liner can be salvaged.
How we do it
We take the chimney down to the point of sound masonry, rebuild with new brick and mortar, set a new crown, and reseal all flashing contact points.
What Chimney Repair Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Mortar repointing (per section) | $250 - $800 |
| Chimney waterproofing | $300 - $600 |
| Full chimney rebuild | $2,500 - $6,000 |
How do I know if my Ontario chimney needs repair or just cleaning?
Cleaning removes surface deposits; repair fixes structural defects. Our camera inspection distinguishes the two definitively. If the flue liner is intact, joints are tight, and the crown is watertight, a sweep is all you need. Call (980) 580-8641 to book an inspection that gives you visual proof.
Will Santa Ana winds worsen existing chimney damage in Ontario?
Yes. Repeated wind loading accelerates mortar joint fatigue and loosens caps, especially on chimneys already compromised by sun damage. Repairs we make include re-securing components against wind pressure. Call (980) 580-8641 for a free written estimate before the next wind event.
Chimney Liner & Rebuild in Ontario
Chimney liner and rebuild work in Ontario starts around $2,200 for a stainless steel liner replacement and runs up to $7,000 to $15,000 for a full chimney rebuild with new liner. Ontario’s 1980s and 90s prefab fireplaces have interior liners that were never built to last beyond 30 years, so many homes in this city are now facing liner replacement as a routine necessity, not a catastrophe. When we recommend a liner, you see the camera evidence first. See Chimney Liner & Rebuild for the full technical detail.
Stainless Steel Liner
Signs you need it
Cracked flue tiles, gaps between tiles that leak smoke into the house, or an old liner that already shows spalling mean a stainless steel liner is the correct fix.
What it costs in Ontario
A stainless steel liner in Ontario runs $2,200 to $4,000 installed, depending on flue height and the liner diameter required.
How we do it
We measure the flue precisely, select the correct alloy and diameter from our DuraFlex or Olympia Chimney stock, and lower the liner into place with the proper top plate and cap.
Flexible Liner
Signs you need it
Homes with offset flue paths or prefab fireplaces that can’t accept a rigid liner often need a flexible liner to negotiate the existing bends.
What it costs in Ontario
A flexible liner in Ontario runs $2,200 to $3,800 installed, which tracks closely with rigid stainless options in most of this city’s tract homes.
How we do it
We feed the flexible liner through the existing flue, connect it to the appliance outlet, and insulate the top to prevent condensation inside the chase.
Liner Replacement
Signs you need it
When the old clay tile liner is cracked, offset, or missing sections, replacement is the only repair that restores a safe, code-compliant flue in an Ontario home.
What it costs in Ontario
Complete liner replacement in Ontario runs $2,200 to $4,500, with partial rebuild work where the surrounding masonry also needs resetting.
How we do it
We remove the old liner, sweep the smoke chamber clear, install the new liner with proper top termination, and document the finished condition with our camera.
Partial Rebuild
Signs you need it
If the masonry below or above the roofline is failing but the core structure is sound, a partial rebuild restores only the damaged section without taking down the whole chimney.
What it costs in Ontario
Partial chimney rebuilds in Ontario run $1,800 to $4,000 depending on how many courses come down and whether the liner can be reused.
How we do it
We demo to sound structure, rebuild the affected section with new brick and mortar, rechamber the smoke area if needed, and reset the crown.
Full Chimney Rebuild
Signs you need it
Structural lean, extensive spalling, or a liner and masonry so compromised that both need full replacement means a full rebuild is the only option that restores safe operation.
What it costs in Ontario
A full chimney rebuild in Ontario runs $7,000 to $15,000, which includes new liner, masonry, crown, cap, and flashing.
How we do it
We take down to below the roofline, rebuild the masonry and smoke chamber, install a new liner, pour a new crown, and resecure all flashing before the final camera pass.
What Chimney Liner & Rebuild Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Stainless steel liner (installed) | $2,200 - $4,000 |
| Liner replacement (complete) | $2,200 - $4,500 |
| Full chimney rebuild | $7,000 - $15,000 |
How do I know if my Ontario fireplace liner is actually failing?
You don’t, until someone puts a camera down the flue. Cracked clay tiles often show no outward sign until smoke or carbon monoxide enters a wall cavity. Our camera footage shows you the exact crack and its location before any recommendation. Call (980) 580-8641 for a recorded inspection.
Is a stainless steel liner in Ontario worth the cost?
Yes, when the old liner is cracked or spalled. A stainless steel liner restores a continuous, code-compliant flue and lasts longer than the remaining service life of most Ontario prefab fireplaces. Call (980) 580-8641 for an exact quote, which is free and written.

FAQs About Chimney Cleaning in Ontario
Most standard chimney cleaning and inspection work requires no permit. Any structural rebuild, liner replacement, or work that alters the roof penetration may require a city building permit, and we handle the permit application on your behalf when the project scope calls for it. We’ll tell you at the written quote stage.
No. Ontario sits within the South Coast Air Basin and SCAQMD calls mandatory no-burn days throughout winter when particulate levels rise. On those days, wood fires are prohibited and violations carry fines. We recommend burning only on permitted days and keeping the fireplace inspected yearly regardless.
Most Ontario appointments are scheduled within 2 to 4 business days, and our dispatch is coordinated from the brand’s Inland Empire office, so Ontario is a short, regular route for our crews. Call (980) 580-8641 and a live person takes the call, any hour, any day.
