Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Gelco Chimney Cleaning in Ontario, CA | Ashwood Chimney Sweep
We provide independent Gelco chimney cleaning and repair across Ontario, CA, including Gelco service in Montclair, ZIP codes 91762, 91764, 91798, and 91758. Most Ontario homes with Gelco caps and vents need debris clearing after Santa Ana wind events, not heavy creosote removal, and that’s where our crew spends most of its time. Norm Castillo has been working Inland Empire flues for close to two decades, and we carry OEM-equivalent Gelco caps, Type B sections, and liner hardware so repair work doesn’t stall waiting on parts. Call (833) 805-3229 for a free estimate.
Why Ontario Residents Choose Us for Gelco Service
Gelco flues and caps show up all over Ontario’s tract housing, so our sweeps have pulled, inspected, and re-capped hundreds of them. We know the metal, the seams, and how they age in inland heat. Norm Castillo grew up off Sierra Avenue in Fontana and trained at Chaffey College’s HVAC and building systems program before narrowing his focus entirely to chimneys, flues, and venting systems, and he’s been working Ontario and the surrounding Inland Empire ever since. When a Gelco cap is bent loose at the collar or a Type B vent joint has lost its twist-lock engagement, we’ve seen it enough times to know exactly what we’re looking at before the ladder goes up. We’re an independent chimney service, not a Gelco dealer or authorized rep, which means we recommend whatever fix actually serves the homeowner, whether that’s an OEM-equivalent part or a better aftermarket option. For the full picture of our Gelco sales & service experience, we stock the parts that matter locally and skip the parts that don’t.

Common Gelco Chimney Cleaning Problems We Solve in Ontario
- Wind-bent and loose Gelco vent caps. Santa Ana gusts hit Ontario hard, especially along the 91761 and 91764 corridors. Gelco caps that were seated years ago get pried loose at the collar, then birds and palm debris drop straight into the flue. We re-seat or replace the cap and clear whatever came down with it.
- Rusted-through galvanized connector pipe and single-wall runs. Ontario’s dry inland heat doesn’t rot metal the way coastal salt air does, but decades of heat cycling still pits and thins galvanized Gelco pipe at the seams. When the seam goes, flue gas leaks or draft goes weak, and we see this regularly on mid-century single-story tract homes near downtown.
- Separated Type B gas vent joints on converted gas-log inserts. Twist-lock joints on Gelco Type B vent sections can back off over time, especially when the unit’s been serviced by someone who didn’t fully seat the joint. That causes draft problems and spillage into the room. We find a lot of this on 1980s and 2000s two-story homes in Ontario’s newer east and south subdivisions.
- Crushed or corroded flexible Gelco liner tops at the crown. Ontario’s summer sun bakes masonry crowns until they crack, and the collar where a Gelco flexible liner meets that crown takes the brunt. When the crown shifts, the liner top crushes or corrodes, and water starts finding its way down.
- Sun-cracked caps and dampers on original equipment. Many Ontario homes still run the original cap and damper from a 1980s pre-fab install. After thirty or forty years of inland heat, the cap’s rusted and the damper’s seized. We replace them before the next rain gets through.
Gelco Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario sits in a Santa Ana wind corridor, and that fact shapes Gelco service here more than any other single thing. Most chimney work in this city is not creosote sweeping. It’s cap and flue clearing after wind events that drive debris and birds into flues along the 91761 and 91764 corridors, plus a steady stream of gas-log fireplace tune-ups on 1980s pre-fab units. We get called out after a blow, and what we pull out of a Gelco-capped vent is typically a bird nest, palm fronds, dust, and whatever else the wind carried in. Those same calls often reveal sun-cracked crowns on pre-fab units that need coating before the next rain, because Ontario’s intense summer heat has been quietly doing its damage for years. Our Ontario service area covers both downtown corridors and the newer east-side subdivisions, and the work shifts accordingly: mid-century masonry fireplaces downtown, pre-fab metal units east of the 15. After one Santa Ana event, our crew was called to a 1980s two-story tract home off the 91761 corridor where the homeowner heard scratching and a downdraft from a Gelco-capped gas-log fireplace. We pulled a bird nest and wind-blown palm debris from the Type B vent, found the Gelco cap bent and loose at its collar, and replaced it with a properly seated cap while re-seating the separated twist-lock vent joint. Draft restored and no more debris in the flue.
Gelco Models & Products We Service in Ontario
We work on the Gelco product lines that show up most in Ontario homes: galvanized single-wall stovepipe and connector runs, Type B gas vent double-wall sections on gas-log inserts, stainless flexible chimney liner kits, and universal and multi-flue vent caps. When fit matters, we match Gelco components with OEM-equivalent parts, and we stock caps, Type B sections, and liner hardware locally so Ontario turnaround stays fast. For standard caps and dampers where fit is less critical, we use quality aftermarket pieces that hold up better to inland heat. When a Gelco vent or liner is rusted through or undersized for the appliance, we tell owners honestly whether repair or replacement makes more sense than patching. A clean flue isn’t a luxury – it’s just the job done right.

AfterGelco Service Pricing in Ontario
Gelco chimney cleaning in Ontario typically runs $149 to $280 for a standard sweep and inspection, depending on flue height, accessibility, and how much debris has accumulated. Cap replacement with a quality Gelco-equivalent or aftermarket cap usually adds $80 to $220, including the part and the ladder work. Level 2 inspections, which are camera-based and look inside the flue for cracked liners or separated Gas B vent joints, run $299 to $450 in Ontario. Gas-log fireplace tune-ups, which are common here, fall between $120 and $220. If a Gelco flexible liner needs full replacement, that’s a bigger job at $1,800 to $3,200 on average, but we only quote that after a camera inspection shows the liner actually needs it. Your estimate is free, and we show you photos before any repair is recommended. Call (833) 805-3229 for exact numbers on your setup.

FAQs – Gelco Chimney Cleaning in Ontario
Yes. We match Gelco vent caps, Type B gas vent sections, and flexible liner hardware with OEM-equivalent parts where fit and performance depend on it. For standard caps and dampers, we use quality aftermarket options that often outlast the original in Ontario’s inland heat. We’re independent, not factory-authorized, so we recommend based on what works, not what a brand program tells us to push. If you need a specific Gelco part quoted, call (833) 805-3229 and we’ll price it out.
Most Gelco chimney cleanings in Ontario take 45 to 90 minutes on site. A standard sweep and inspection on a single-story tract home is typically under an hour. If we’re also replacing a wind-damaged cap or re-seating a Type B vent joint, plan for 90 minutes to two hours. We work by appointment, not dispatch windows, so you know when we’re coming.
We service Gelco galvanized single-wall stovepipe and connector runs, Gelco Type B gas vent double-wall sections, Gelco stainless flexible chimney liner kits, and Gelco universal and multi-flue vent caps. Those are the Gelco lines installed across Ontario’s mid-century and 1980s housing stock, and we also handle Gelco in Upland. If you’re unsure what’s on your roof, we’ll identify it during the inspection and tell you exactly what you have.
In Ontario, expect $149 to $280 for a standard Gelco chimney cleaning and inspection, with cap replacement adding $80 to $220 if wind damage is found. Level 2 camera inspections run $299 to $450, and gas-log tune-ups on converted Gelco-vented fireplaces cost $120 to $220. The biggest cost driver in Ontario is usually cap and crown condition, not creosote, because the Santa Ana winds and summer sun do more damage than fires do. Call (833) 805-3229 for a free estimate and we’ll give you a flat price before any work starts.
Most Ontario homes with Gelco vents are gas-log inserts, and those still need service, just not for the same reason as a wood-burning fireplace. Gas logs produce little creosote, but the vents collect dust, spider webs, wind-blown debris, and bird nests. A blocked or partially blocked Type B vent causes the gas log set to spill carbon monoxide into the room instead of venting it outside. We find separated twist-lock joints on Ontario gas-log vents regularly, and those need to be re-seated before the draft works right again—same issue we see with Gelco repair in Chino.
