This page is for Pasadena homeowners who have a Gelco fireplace, insert, or stove and want to know what a proper sweep involves on their specific unit. You will not find fluff here. You will find what fails, what it costs, and how we work.

How Gelco Products Fail – and How We Fix Them

• Gelco direct-vent gas fireplace series – glass seal degradation. The ceramic glass gasket on Gelco direct-vent units loses its seal after about 5 to 7 years of heating cycles. When that seal goes, the combustion chamber pulls room air in through the gap, which cools the flue gasses and accelerates creosote-like deposits on the glass and inside the firebox. We see this frequently in Pasadena homes near the Arroyo Seco where winter temperature swings stress the seal. Our fix is a sweep, a gasket inspection, and replacement with a rated gasket material when the seal shows flattening or cracks.
• Gelco wood-burning fireplace with refractory panels – panel cracking from thermal shock. Gelco’s older wood-burning models used refractory brick panels that crack when homeowners burn hot fires after long idle periods. That is not a manufacturing defect; it is physics. The crack lets heat reach the metal firebox shell directly. During a sweep we check panel condition and flag any crack wider than about 1/16 inch. If it needs replacement, we quote a flat price before starting. If it can wait, we say so plainly.
• Gelco inserts with air-wash systems – clogged air channels. The air-wash system that keeps Gelco glass clean pulls air through small channels at the top of the insert. After a few seasons of burning, fine ash and dust clog those channels. The symptom is glass that stays dirty no matter how often you wipe it. A basic sweep does not address this. Our Gelco service includes pulling the air-wash deflector and clearing those channels, which is something no generic chimney sweep will do unless they know the unit.
• Gelco vent-free units – white powdery residue on logs. Vent-free Gelco models running on natural gas in Pasadena produce a fine white silica-like film on the ceramic logs over time. That is normal combustion byproduct, not a failure. But it does need removal, and you cannot just wipe these logs with a household cleaner without risking damage to the ceramic finish. We use the proper cleaning method for Gelco’s log material, and we check the oxygen depletion sensor at the same time.
• Gelco chimney liners – creosote adhesion on stainless flues. When Gelco units are connected to existing chimneys with stainless liners, the liner itself can hold onto creosote differently than a clay tile flue. Smooth stainless should shed creosote better, but if the unit was run with the damper partly closed or with unseasoned wood, we see hard glaze deposits that a rotary brush alone will not remove. We carry the right tools for that job and do not have to schedule a second visit.

Our Gelco Chimney Sweep Process

Here is exactly how a Gelco chimney sweep works when you call Flint Chimney Co Pasadena.

1. 1
   You call (626) 657-5513. A live person answers. We ask what Gelco unit you have, the last time it was swept, and what you have noticed. We book a window that we actually keep.
2. 2
   We arrive and assess before anything comes off the truck. We look at the unit, the chimney run, and the surrounding hearth area. You get a written price for the sweep and any recommended repairs. That number does not change unless we find something that genuinely changes the scope – and if that happens, we stop and get your approval in writing before proceeding.
3. 3
   We protect the work area. Drop cloths go down around the hearth. The area is sealed so dust does not migrate into the rest of your Pasadena home.
4. 4
   We sweep the full system. This includes the flue, smoke chamber, damper assembly, firebox, glass, logs or refractory panels, and the air-wash channels on Gelco inserts. We use brushes sized to your specific chimney, not one brush for everything.
5. 5
   We test and clean up. We run the draft check to confirm smoke pulls properly, clean every surface we touched, and do a final walkthrough with you. You get a written service summary with what we found, what we did, and what to watch.
6. 6
   Your guarantee is in writing before we leave. If any covered repair fails within 365 days, we come back at no charge. That is the 365-Day Done Right Promise, and it is on every invoice.

What Gelco Chimney Sweep Costs in Pasadena

Here are the price ranges you can expect for Gelco work in Pasadena, based on the jobs we do most often.

• Standard Gelco sweep (open fireplace, accessible flue): $189 – $249
• Gelco insert sweep with air-wash channel cleaning: $229 – $289
• Glass gasket replacement on Gelco direct-vent units: $120 – $220 depending on unit size
• Refractory panel replacement: $180 – $320 per panel, depending on the model
• Level 1 inspection paired with a sweep: add $49 – $89
• Level 2 inspection (real estate, chimney changes, suspected damage): $199 – $349

The main thing that moves the price is how much creosote is in the flue and whether the unit has serviceable parts that need attention. A Gelco that has been maintained yearly is usually the low end of the range. One that has been ignored for five years takes longer and costs more. Call (626) 657-5513 for an exact quote. Estimates are free, and the written price you get before work starts is the price you pay.
