Pricing & Estimates
How much does chimney cleaning service cost?
Chimney cleaning in Ontario typically costs between $150 and $350, with most standard sweeps landing in the $180 to $260 range. The price depends on how much creosote has built up, whether the flue is easy to access, and whether we’re sweeping one chimney or several at a property. A heavy, glazed creosote situation takes longer and costs more, but it’s also the situation that most needs fixing. If you’re comparing quotes, ask each company what their price includes – a sweep that skips the video inspection isn’t the same job. Call (833) 467-7685 for a free estimate on your specific chimney.
Why do chimney cleaning prices vary so much in Ontario?
Prices vary because the job varies – a poorly drafted flue, a firebox full of ash, or a chimney with a history of chimney fires takes more time and care. We use professional-grade equipment and check the flue liner, cap, and damper while we’re up there, which is more than a quick brush offers. We don’t quote a low number and then nickel-and-dime you on the back end. The estimate we give is the price you pay unless you approve additional work.
Do you offer free estimates?
Yes, we offer free estimates for chimney repair and dryer vent cleaning work. For a standard sweep, we can give you a firm quote over the phone once we know the type of system and roughly how long it’s been since it was last cleaned. If the inspection turns up something that needs attention, we show you the photos and explain the options before any work starts.
Is it cheaper to repair a chimney or replace the flue liner?
Repair is usually cheaper when the liner damage is localized, which is where HeatShield ceramic resurfacing comes in. HeatShield is a proprietary ceramic material applied to the inside of the flue, and it restores a structurally sound, code-compliant chimney at a fraction of the cost and disruption of a full tear-out and reline. When the flue is too far gone, a DuraFlex stainless steel liner is the long-term fix, and we’ll tell you honestly which one your chimney needs. Call (833) 467-7685 and we’ll walk you through both options for your situation.
How much does a dryer vent cleaning cost?
Dryer vent cleaning usually runs between $100 and $200, depending on the length of the vent run and whether we can reach it from the outside. Dryer vents are a leading cause of house fires – the NFPA and CPSC track this every year – and cleaning them is maintenance, not an optional add-on. We treat it as a standalone fire-safety service, and we clean the full run, not just the section nearest the dryer.
Service & Scheduling
Do you offer emergency chimney cleaning service?
We prioritize urgent calls when a chimney is blocking, smoking into the house, or has just had a fire, and we’ll do everything we can to get to you quickly. True emergencies are rare, but when one happens, a blocked or compromised flue is not something to leave until next week. Call (833) 467-7685 and tell us what’s going on – we’ll tell you what we can do and when.
How fast can you respond?
For standard appointments in Ontario, we can usually schedule within a few business days and often sooner depending on the season. Fall and early winter are our busiest months, so if your fireplace is going to be in regular use, it pays to book before the cold snaps. Emergencies and safety concerns get moved to the front of the line. Call and we’ll give you a realistic window rather than a vague “sometime this week.”
Do you handle chimney cleaning & sweep?
Yes – chimney sweeping is one of our three core services, alongside dryer vent cleaning and chimney repair. Our technicians sweep the firebox, flue, and smoke chamber, then check the liner, cap, damper, and masonry for problems. Our Chimney Sweep in Ontario service covers routine annual maintenance and post-season cleanings. Your flue handles combustion gases every time you light a fire – it deserves more than a quick brush.
How often should a chimney be swept?
A chimney should be swept at least once a year if you burn wood regularly, and more often if you burn frequently or notice buildup. The CSIA recommends inspection annually, and the sweep frequency depends on how much wood you burn and how well your fire draws. Creosote builds up in stages, and the glazed, hardened form is the one that fuels chimney fires. An annual sweep catches that before it becomes a repair bill.
Do you clean dryer vents even if you’ve never cleaned the chimney?
Yes – dryer vent cleaning is a standalone service and you don’t need to book a chimney sweep to get it. We run a camera or brush through the full vent line, clear lint and debris, and check the exterior vent flap and termination. If your dryer takes two cycles to dry a load, that’s usually a sign the vent line is restricted. Book the vent cleaning and we’ll show you what came out.
Do you handle fireplace services?
We handle the chimney and venting side of fireplace service – sweeping, inspection, liner work, caps and dampers, and masonry repair. We don’t sell or install fireplace inserts or gas log sets, but we’ll service the flue and venting those systems rely on. If your fireplace isn’t drafting or you’re seeing smoke in the room, call us and we’ll diagnose the venting side of the problem.
Licensing & Trust
Are you licensed and insured?
Ontario Chimney is properly insured and operates as a professional chimney and venting specialist, and we’re happy to share the details of our coverage with you directly. Our technicians use professional-grade materials from brands the trade actually specifies – DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. We’re not a pressure-wash crew that added chimney sweeping to a list. Call (833) 467-7685 and we’ll answer any coverage question you have before you book.
Do you guarantee your work?
Yes – we stand behind our work, and if something we did isn’t right, we come back and make it right. We’ll tell you what we found, show you the evidence, and give you options, so the scope of the work is clear before we start. If a repair or install doesn’t perform the way it should, that’s on us to resolve. Ask us about the specifics of our guarantee when we’re on site.
What brands and materials do you use?
We use DuraFlex flexible liner systems for relining, HeatShield ceramic resurfacing for flue restoration, and Gelco and Famco components for caps and dampers. Our supply comes through Olympia Chimney and Copperfield, the two largest professional chimney supply distributors in the trade. These are the materials certified chimney professionals specify – not hardware-store substitutes. That matters when the liner is going to live inside your chimney for decades.
What payment methods do you accept?
We accept standard payment methods including major credit cards and check, and we’ll confirm the options when we book your appointment. For larger repair and reline jobs, we’ll go over the payment schedule with you up front so there are no surprises. Ask us when you call if you have a specific payment method in mind.
Do you work with landlords and property managers?
Yes – we serve landlords, property managers, and multi-unit property owners who need documented, reliable service across several units. We can sweep and inspect a full property in a single visit, keep records of what was found in each unit, and flag anything that needs repair before it becomes a tenant complaint. If you manage multiple properties in the area, call us and we’ll set up a service schedule.
Specific Services
Do you handle chimney repair?
Yes – chimney repair is one of our three core services, and it covers everything from caps and crowns to flue relining and masonry work. We handle the full repair scope so you deal with one company from inspection through completion, rather than coordinating a sweep crew and a separate mason. That continuity is why homeowners call us back. We use DuraFlex liners for complex relines and HeatShield for flue restoration, and we’ll tell you which your chimney actually needs.
Do you handle chimney cap & crown?
Yes – we repair and install chimney caps and crowns, and we use Gelco and Famco components for the caps and damper systems we spec. A missing or rusted-out cap lets water and animals into the flue, and a cracked crown is one of the most common causes of water damage to a chimney. This is a small repair that prevents a large one. Ask us to check your cap and crown at your next sweep.
Can you fix a chimney that smokes into the house?
A chimney that smokes into the house usually has a draft problem, and the fix depends on what’s causing it – a blocked flue, an undersized liner, a negative pressure issue, or a damaged smoke chamber. We diagnose the venting side and show you what we found before recommending a repair. Sometimes it’s a sweep. Sometimes it’s a liner. We don’t guess. Call (833) 467-7685 and describe what you’re seeing.
What areas do you serve?
We serve Ontario and the surrounding communities in the Inland Empire, and we handle jobs across the wider San Bernardino and Riverside County area. The climate here matters – hot, dry summers followed by winter burn season means creosote dries and cracks differently than it does in colder, wetter regions, and we account for that. If you’re not sure we cover your address, call us and we’ll tell you straight. You can also start from our home page to see our full service area.
Can you inspect a chimney before I buy a house?
Yes – a chimney inspection before you close on a home is money well spent. We check the flue, liner, cap, crown, firebox, and damper, and give you a written summary of what we found and what it would cost to fix. A chimney that looks fine from the driveway can have a cracked liner or a missing cap. If you’re in escrow and need an inspection quickly, call (833) 467-7685 and we’ll see what we can fit in.
How does a chimney sweep actually work?
A professional chimney sweep is a multi-step process, and here’s how we do it from start to finish:
- Protect the room. We lay drop cloths and set up containment so soot stays in the flue, not on your floor.
- Inspect the firebox and flue. We check the damper, smoke chamber, and liner condition before we brush, so we know what we’re dealing with.
- Brush the flue. We run brushes through the full chimney from the top and the firebox, then vacuum the debris with a HEPA setup.
- Check the exterior. Crown, cap, flashing, and masonry get a visual inspection from the roof or ladder.
- Show you the result. We walk you through what we found, with photos, and tell you if anything needs repair.
That last step is where a lot of companies stop short. We won’t just tell you the chimney needs work – we’ll show you the evidence before you spend a dollar on a repair. Book a sweep or call (833) 467-7685 with questions.
Should I clean my chimney before or after the burning season?
Late summer or early fall is the best time to sweep, so your chimney is clean and ready before the first fire of the season. A pre-season sweep also gives you time to schedule any repairs before the cold actually arrives, when everyone else is also calling. If you’ve already burned through a winter, a spring cleaning clears the creosote before it has a whole summer to set up. Either way, once a year is the baseline.
What if my chimney hasn’t been cleaned in years?
A chimney that hasn’t been cleaned in years likely has heavy or glazed creosote, and that needs to be removed before you burn again – a chimney fire risk is not worth a season’s worth of fires. We start with an inspection to see how far the buildup goes, then sweep and assess the liner. If the liner is compromised, we’ll tell you whether HeatShield resurfacing or a DuraFlex reline is the right path. Call us at (833) 467-7685 before you light the next fire.
