Chimney Cleaning Services in Ontario, CA
Ontario homeowners typically pay $180-$340 for a professional chimney cleaning and Level-2 camera inspection, with same-week scheduling available throughout the 91762, 91764, 91798, and 91758 ZIP codes. Hearthstone Chimney Co. has worked Ontario’s chimneys since 2014 - from the mid-century masonry stacks near Euclid Avenue to the prefab units in newer Ontario Ranch developments. Call (844) 803-1545 and a live person answers, any hour, any day.
We’ve swept chimneys after Santa Ana wind events have packed debris down flues. We’ve documented cracked terra-cotta tiles in 1960s tract homes that the homeowner never knew were there. Ontario’s particular mix of aging housing stock, SCAQMD burn restrictions, and pass-driven wind patterns creates chimney conditions you won’t find in neighboring cities. We know what to look for because we’ve been looking here for more than a decade.

Why Ontario Homeowners Choose Hearthstone Chimney Co.
Our technicians know the difference between a 1955 masonry fireplace on an original Ontario tract lot and a 2012 zero-clearance box in Ontario Ranch. That distinction matters for how we clean, what we inspect, and what we warn you about. We’ve earned our reputation in this city one appointment at a time - background-checked, uniformed techs who arrive when we say, explain what they found in plain English, and leave the work area cleaner than they found it.
Homeowners in the older grid near downtown Ontario, around Holt Boulevard and the 91762 ZIP code, call us back because we photograph the damage they can’t see from below and show them the evidence. In the 91764 neighborhoods stretching toward the 60 Freeway, they appreciate that most jobs finish in a single visit with upfront pricing - the number on the estimate matches the number on the invoice. No renegotiating in the driveway, no surprise add-ons.
The 90-Day Done Right Promise governs every job: if it’s not right, we make it right, backed in writing with no paperwork and no arguing. We’ve operated this way for over 42 years, since 1984, because we plan to be sweeping Ontario chimneys thirty years from now. That changes how you treat people today.
Chimney Cleaning Services We Offer in Ontario
Chimney Cleaning & Sweep
Our Ontario chimney sweeps use professional-grade brushes and vacuums to remove creosote, soot, and debris from masonry and prefab systems alike. Every cleaning includes a basic visual inspection of accessible components. Learn more about our Chimney Cleaning & Sweep in Ontario.
Chimney Repair
We rebuild deteriorating mortar joints, replace damaged flue tiles, and repair crown cracks using materials from Olympia Chimney and Copperfield - brands we trust because they’ve held up in Ontario’s dry, thermally stressed climate. Learn more about our Chimney Repair in Ontario.
Fireplace Services
From damper adjustments to firebox refractory panel replacement, our fireplace work restores safe, efficient operation to systems that have seen decades of Ontario’s concentrated winter use. Learn more about our Fireplace Services in Ontario.
Chimney Cap & Crown Installation
A proper cap stops the Santa Ana debris that funnels through the Cajon Pass from entering your flue. We install Famco and Copperfield caps sized to your specific chimney, with crowns poured or repaired to shed water correctly in Ontario’s rare but intense rain events. Learn more about our Chimney Cap & Crown in Ontario.
Chimney Liner & Rebuild
When clay tiles have cracked beyond repair or a prefab liner has failed, we install DuraFlex stainless steel liners or complete partial rebuilds using professional-grade materials. See our Chimney Liner & Rebuild in Ontario for details. Every liner installation ends with a camera verification and written documentation.

Why Ontario’s Climate & Housing Affect Chimney Cleaning
Ontario sits directly downwind of the Cajon Pass, one of the primary Santa Ana wind corridors into the Inland Empire. Every fall, those winds drive debris, dust, and nesting birds deep into chimneys across the city. We’ve pulled twig nests from flues in the 91762 ZIP code that were packed solid by a single October wind event. This isn’t a generic “debris happens” situation - it’s a geographic certainty for Ontario that demands proactive inspection.
The South Coast AQMD’s “No Burn” curtailment days add another layer unique to SCAQMD-regulated cities like Ontario. Residents must concentrate all their fireplace use into a handful of permitted nights, creating accelerated creosote buildup in a compressed window rather than gradual accumulation across a full season. A chimney that might have distributed its creosote load over three months in an unregulated city packs that same deposit into three weeks here. We see the result every January: flues that were “fine” in November are hazardous by February.
Meanwhile, Ontario’s semi-arid climate means low humidity and prolonged dry spells that accelerate mortar joint deterioration on older masonry chimneys. The 1950s-1970s tract homes dominating the 91762 and 91764 ZIP codes have original clay-tile flue liners that have spent decades exposed to seismic stress and thermal cycling. Our technicians regularly find terra-cotta tiles cracked by the 1992 Big Bear/Landers-era seismic sequence and subsequent quakes - damage invisible from the firebox below but caught only with a camera inspection. This code-compliance point is far more common in Ontario’s aging housing stock than in newer Inland Empire suburbs.
The rapidly expanding Ontario Ranch area presents the opposite challenge: 2000s-2010s production homes using zero-clearance prefab fireboxes that require an entirely different cleaning and inspection protocol than masonry. We carry the tools and training for both.

FAQs About Chimney Cleaning in Ontario
Most Ontario homeowners pay between $180 and $340 for a professional chimney cleaning, depending on whether a Level-2 camera inspection is included and how much creosote has accumulated. Heavy glazed buildup from concentrated winter use under SCAQMD restrictions can push the price toward the higher end. Call (844) 803-1545 for a free estimate - we’ll give you an exact number before any work begins.
The National Fire Protection Association recommends annual inspection, with cleaning as needed. In Ontario, we advise cleaning after every cord of wood burned, or annually for regular fireplace users, because SCAQMD “No Burn” days compress your firing season into fewer nights with heavier per-use buildup. If you’re in the 91762 or 91764 ZIP codes with an original mid-century masonry chimney, the combination of aging clay tiles and accelerated creosote makes annual camera inspection especially prudent.
We answer the phone with a live person 24 hours a day, 7 days a week, and we maintain same-week availability for standard cleanings throughout Ontario. Emergency situations - a blocked flue, smoke backing up into the house, or suspected animal intrusion - get priority scheduling. Call (844) 803-1545 and we’ll tell you exactly when we can be there.
For Ontario’s older homes with cracked clay tiles, a stainless steel liner from DuraFlex is almost always more cost-effective than a full tear-out and rebuild of the flue. A liner runs $1,800-$3,500 installed versus $4,000-$8,000+ for reconstruction. We only recommend what we’d do in our own homes - and we document the damage with photos so you can see why we’re making the call. Call (844) 803-1545 for a free second opinion on any written estimate you’ve already received.
Yes - especially in Ontario. The terra-cotta flue tiles in mid-century homes throughout the 91762 and 91764 ZIP codes commonly crack from decades of seismic stress and thermal cycling. That damage is invisible from the firebox. Our Level-2 camera inspection sends a high-resolution device up the flue, and we show you the photos with a plain-English verdict. We’ve found cracked tiles in chimneys that had “passed” visual checks for years. The inspection takes 30 minutes and is included in our comprehensive cleaning package.
