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
Gelco chimney cleaning in Ontario usually involves a full sweep, firebox inspection, and a Level 2 camera check when the insert sits in an older masonry flue, and we typically complete it in one visit. What makes our Gelco work different in Ontario is that we expect the cracked clay flue behind the gas insert, not just creosote on the firebox walls. Since 2008, Noel Strickland and our crew have serviced Gelco inserts, log sets, and doors across Ontario’s 91762, 91764, and 91758 ZIP codes as an independent provider, not a manufacturer affiliate. Call (877) 358-0941 for a free estimate and we’ll tell you what your unit actually needs.
Why Ontario Residents Choose Us for Gelco Service
We have serviced Gelco fireplaces and inserts across Ontario for years, and the failures we see are consistent: dry heat cycles crack firebox brick, settles flue tiles, and causes damper linkages to bind. Our independent expertise comes from that repetition, not from any Gelco authorization, which matters when you need an honest fix rather than a brand script. Noel grew up in the Carbon Canyon corridor of Chino Hills and trained in heating and venting systems through the HVAC program at Chaffey College in Rancho Cucamonga before narrowing his focus to chimney work, so when we open a Gelco firebox, we are looking for how the vent is actually behaving, not just whether the glass is clean. We show you photos of what we find inside the flue, the firebox, and the damper before we recommend any repair, and we keep Gelco sales & service knowledge current on new insert models so your older unit gets the same attention as a newer one.

Common Gelco Chimney Cleaning Problems We Solve in Ontario
- Cracked and spalled firebox brick from dry heat cycling. Ontario’s summers bake masonry for months, and Gelco inserts installed in 1940s and 1950s tract homes near downtown show brick faces that flake and pop loose. We remove the loose material, assess whether the firebox is structurally sound, and repair with refractory cement rated for repeated heat exposure.
- Damper linkage failure in Gelco wood-burning inserts. The damper arm on older Gelco units warps from repeated heating and cooling, and in Ontario’s mild but dry winters, homeowners rarely notice until the damper is stuck open and heat is pouring up the flue. We free the linkage, replace the arm if it is beyond adjustment, and make sure the damper seats fully when closed.
- Gas log sets with clogged burner ports or failing thermocouples. Ontario’s hard water and dust settle into burner ports over the summer, and when you light the logs in November, the flame is weak or the pilot will not hold. We clean the burner assembly, test the thermocouple with a multimeter, and replace safety components with OEM Gelco parts only.
- Prefab Gelco flues with degraded gaskets or loose joints. In tract homes from the 1970s and 1980s on Ontario’s east side, the factory flue sections behind Gelco prefab fireplaces have gaskets that dry out and crack. Hot gases can leak into wall cavities, so we inspect with a camera, reseal joints, and replace gasket material where the flue path has separated.
- Clay flue tiles cracked behind gas inserts. The most common Gelco-related failure we see in older Ontario homes is not the insert itself, but the original masonry flue behind it. Decades of thermal expansion and settling in the valley’s dry clay soil crack the tiles, and a gas insert running on that flue vents poorly, pushing carbon monoxide back into the room. A Level 2 inspection catches this before it becomes dangerous.
Gelco Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario’s clay tile flue liners often crack from thermal expansion as the ground settles in the hot, dry valley, especially in older homes on the east and south sides, so a Level 2 inspection is essential before using a gas insert. Here is what that means for Gelco owners specifically: the insert’s factory flue may be fine, but the masonry chimney it vents into is failing. You will not see that from the living room, and you will not know it until a camera goes up the flue. In a 1950s tract home near downtown Ontario, CA, we inspected a Gelco gas insert and found the original clay flue tiles had cracked and spalled from decades of heat cycling, with debris blocking the vent. We performed a Level 2 inspection, repaired the firebox with refractory cement, and installed a new stainless liner to vent the insert safely. That is the work most sweep-only companies in Ontario walk past, because they are not set up to do anything about it.
Gelco Models & Products We Service in Ontario
We service Gelco gas fireplace inserts, wood-burning inserts, decorative gas log sets, and Gelco fireplace doors and screens across Ontario. For critical safety components like thermocouples and dampers, we use OEM Gelco parts, because a mismatched part in a gas valve or damper arm is not worth the risk. For cosmetic pieces like door trim or screen panels, we use high-quality aftermarket parts when they meet or exceed OEM specs, which keeps your repair cost down without cutting corners. We stock common Gelco replacement components at our Gelco repair in Chino area shop, so most Ontario repairs do not wait on a parts shipment.

AfterGelco Service Pricing in Ontario
Chimney sweeping in Ontario generally runs from $180 to $340 depending on flue height, access, and how much buildup has accumulated since the last cleaning. A Level 2 inspection adds $100 to $250, and firebox repair with refractory cement typically starts around $300 for isolated spalling. The honest variable in Gelco service is what the camera finds behind the insert: a clean flue is a simple sweep, but a cracked clay liner changes the scope, and we will walk you through that cost before any work begins. Call (877) 358-0941 for an exact quote, and we will send you a written estimate with photos of what we found.

FAQs – Gelco Chimney Cleaning in Ontario
A Level 2 inspection is necessary because the original clay flue behind your Gelco insert was built for open wood fires, not a sealed gas unit, and decades of Ontario heat and ground settling often crack those tiles. If the flue is compromised, your gas insert vents exhaust into the chimney cavity instead of outside, and carbon monoxide can back up into the living space. We run a camera the full length of the flue, show you the video, and confirm the vent is clear before you run the insert another season. Call (877) 358-0941 to schedule an inspection; we service all Ontario ZIP codes.
The clearest signs are a damper handle that feels loose or gritty when you move it, smoke that rolls back into the room on startup, or a damper that will not stay fully open. In Upland and Ontario wood-burning inserts, the linkage that connects the handle to the damper plate warps with repeated heat cycles, and Ontario’s dry air accelerates the metal fatigue. We free the mechanism, replace the linkage if needed, and verify the damper seats properly before we call the repair done.
Most spalling we see in Ontario Gelco fireplaces is isolated to a few brick faces, and that is repairable with refractory cement and proper surface preparation. If the underlying brick has lost more than a third of its thickness or the firebox is pulling away from the wall, we will tell you honestly that a rebuild is the better long-term value. We never recommend a rebuild without showing you photos of why, and we price repairs so you can decide with the evidence in front of you.
Ontario’s climate damages Gelco fireplaces in two ways. The hot, dry summers bake the firebox and flue, causing clay tiles and brick faces to crack and spall, and the Santa Ana winds blast dust and debris onto the chimney crown, where it works into the flue. Winter rain is less of a factor here than in coastal cities, but a cracked crown will still let water into the firebox during a heavy storm. An annual inspection catches these problems before they become fire hazards, and a sweep clears the dust that Ontario’s wind deposits in the flue. Call (877) 358-0941 to get on the schedule before the next Santa Ana season.
Yes, we service Gelco gas log sets that light weakly, won’t stay lit, or show uneven flame patterns across the burners. Most of these problems trace to clogged burner ports from Ontario’s dusty air, a dirty pilot assembly, or a thermocouple that is producing borderline millivolt readings. We clean the burner, test the thermocouple under load, and replace it with an OEM Gelco part if it falls below spec, whether we’re doing a Gelco repair in Jurupa Valley or here in Ontario. The fix is usually same-visit, and we show you the flame pattern before we pack up.
