Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterGelco Chimney Cleaning in Fresno, CA | Alcott Chimney Sweep
We’re Alcott Chimney Sweep, and we service Gelco fireplaces, inserts, and factory-built units throughout our Fresno service area. We’re an independent chimney company, which means we’re not authorized by or affiliated with Gelco, but we’ve worked on their systems here long enough to know exactly how Fresno’s no-burn cycles change the way they soot up and fail. If you own a Gelco unit in Fresno, you need a sweep who understands both the equipment and the San Joaquin Valley Air Pollution Control District calendar. Call (336) 863-3889 and we’ll walk you through what your fireplace actually needs.
Why Fresno Residents Choose Us for Gelco Service
Most chimney companies can sweep a flue. Fewer know what a Gelco ZC Series zero-clearance box should look like after three idle winters in a 1950s Tower District ranch house. We carry the gaskets, baffle boards, and refractory panels these units actually use, and we’re honest about when an OEM part matters and when a vetted aftermarket piece does the same job for less. Ruben Castellano, Alcott’s owner, spent two decades working chimneys across Los Angeles before this role, and he trained his crews to tell you what they found, what it means, and what it costs before any work starts. Written price first. Always. That’s simply how we operate.
Common Gelco Chimney Cleaning Problems We Solve in Fresno
Fresno’s burn restrictions create failure patterns we see over and over in Gelco equipment. Here’s what actually goes wrong here:
- Flattened door gaskets on Gelco inserts. When SJVAPCD shuts down wood burning for weeks, units sit cold and the gasket compresses and dries out. The first legal burn day brings air leaks, smoldering fires, and rapid creosote buildup. We replace these gaskets regularly across Fresno.
- Warped baffle boards and burned-through secondary air tubes. Gelco ZC boxes that idle for months then get hammered with heavy fires in short legal windows develop exactly this. A warped baffle kills secondary combustion and fills the flue with smoke.
- Pitted firebox liners and damper-frame corrosion. Fresno’s Tule fog season holds moisture against metal fireplaces for weeks. Gelco fireboxes show rust and pitting faster here than in drier foothill cities.
- Bird and mammal nesting in idle fireboxes. European starlings and Western Screech-Owls find their way into Gelco factory-built units whose owners stopped burning during no-burn winters. We’ve pulled nests from dampers in central Fresno more times than we can count.
- Smoke rollback on the first cold night. A cold, damp flue plus an air-starved firebox equals smoke pouring into the living room. Usually it’s a draft issue caused by the nesting, creosote, or gasket problems above, not the fireplace itself.
Gelco Service in Fresno: What Local Conditions Mean for Your Equipment
Here’s what makes Fresno different from any neighboring city: the San Joaquin Valley Air Pollution Control District calls No Burn days throughout winter whenever the valley’s air quality, already among the worst of any U.S. metro, falls below safe thresholds. That means chimneys in Fresno often sit completely cold for weeks or months, then see concentrated heavy use in short, unpredictable windows. For Gelco owners, that idle-then-burn pattern is brutal on gaskets, baffle boards, and damper hardware. It also invites animals. In Clovis, just a few miles northeast, burn restrictions are far less frequent, so starlings and Screech-Owls rarely have time to establish nests. In central Fresno and the Tower District, where homes date from the 1950s to the early 1980s and many fireplaces haven’t been used in three or more seasons, we find nesting in Gelco fireboxes at a rate that would surprise anyone who hasn’t worked here. If your Gelco has been sitting unused because you got tired of no-burn days, do not light it before an inspection. You may be about to burn a bird’s nest.
Gelco Models & Products We Service in Fresno
We clean and service the Gelco ZC Series zero-clearance factory-built fireplaces, the Gelco GC Series fireplace insert, and the 36-inch factory-built wood fireplace with multi-flue cap. On every unit we inspect, we look at the door gasket seal, baffle condition, secondary air tubes, damper operation, and firebox liner integrity. For parts, we source OEM Gelco gaskets, baffles, and refractory panels where they’re still manufactured. When an OEM piece is discontinued or backordered, we’ll tell you and offer a vetted aftermarket alternative, never a box-store substitute. You’ll always know which is which. That transparency matters when you’re deciding between a $40 gasket and a $1,400 firebox replacement.
Gelco Service Pricing in Fresno
A standard Fresno Chimney Sweep on a Gelco unit typically runs $180 to $340 before any repairs. Fireplace cleaning and creosote removal fall within that range depending on how much buildup exists and whether the flue has been idle for years. A Level 2 inspection, which we recommend for any Gelco that has sat through multiple no-burn winters or shows signs of animal activity, adds $150 to $350 depending on the roof access and liner condition. Replacement parts like door gaskets and baffle boards are priced separately and quoted in writing before we order anything. If a firebox is cracked through or the liner is failing, we’ll tell you plainly that replacement is the honest call, not repair. Call (336) 863-3889 for a free estimate on your specific unit. We’ll give you real numbers before any work begins.

FAQs – Gelco Chimney Cleaning in Fresno
My Gelco insert has been idle for two winters because of Fresno no-burn days. Is it safe to just light it?
No, not without an inspection. Two idle winters in Fresno means the door gasket has likely dried out, the baffle may be sagging, and there’s a real chance something nested in the firebox or lower flue. Light a fire in that condition and you risk smoke rollback, poor draft, or an attic-or-worse fire from a compromised component. We’ll inspect, clean, and tell you exactly what’s needed. Call (336) 863-3889 and we’ll schedule you before the next burn window.
Fresno just called a no-burn day. Can you still sweep my Gelco fireplace?
Yes. Sweeping and inspection are not wood burning. SJVAPCD restrictions apply to residential wood combustion, not to cleaning or servicing the appliance itself. It’s actually a smart time to schedule because you’re not losing any legal burn days to the service visit. We work year-round in Fresno, including during no-burn stretches.
Do my Gelco’s door gasket and baffle really need OEM parts?
For gaskets, OEM is usually the right call because the seal profile and material density are matched to the door’s compression pattern. For baffle boards and refractory panels, OEM is ideal when it’s still manufactured, but some older Gelco parts have been discontinued. In those cases, we use vetted aftermarket components from brands chimney professionals actually specify, and we’ll tell you before ordering which route we’re taking. You’ll never get a mystery part with a markup you can’t verify.
Why does my Gelco fireplace smoke into the room on the first cold Fresno night?
Cold, damp flue plus restricted airflow. That first cold snap after a warm stretch means the chimney is chilled and the air inside wants to sink, not rise. If the flue cap is plugged with creosote, a nest, or debris from the fog season, there’s nowhere for smoke to go but back into the room. A door gasket that’s lost its seal makes it worse by letting cold air into the firebox and killing draft. We find this exact combination all over Fresno. The fix is usually a sweep plus a gasket replacement, not a new fireplace.
We found a bird nest in our Gelco ZC firebox in central Fresno. Is that common here?
It’s very common, especially in older central Fresno neighborhoods and Tower District homes where no-burn days mean fireplaces sometimes go unused for entire winters. European starlings and Western Screech-Owls both take advantage of that. We’ll remove the nest, sweep the flue, check for damage from droppings or moisture, and get your unit ready for the next legal burn day. Call (336) 863-3889 and we’ll come take a look, usually within a few days.
