Gelco Chimney Cleaning in Pasadena, CA | Flint Chimney Co Pasadena
We’re an independent Gelco service provider in Pasadena, not a manufacturer-authorized outfit, and that independence means we fix what’s actually broken instead of selling you a replacement you don’t need. A standard Pasadena Chimney Sweep and inspection runs $189 to $389 depending on flue condition and access. The thing that makes our Gelco work different here is the housing stock: Pasadena’s pre-1940 chimneys were built for coal and wood, and most have original dampers, clay tile liners, and fireboxes that modern fire codes never anticipated. Call (626) 657-5513 for a written estimate before any work starts.
Why Pasadena Residents Choose Us for Gelco Service
Hank Delano, our owner, grew up in Los Angeles and learned the trade through the HVAC and sheet metal program at LA Trade-Technical College. He’s been cleaning and inspecting chimneys for going on eighteen years, and his crew has worked jobs from Craftsman bungalows near the Arroyo Seco all the way across the San Gabriel Valley. That matters for Gelco work because older Pasadena homes have quirks you won’t find in a newer track house: shallow fireboxes, unlined flues, dampers that haven’t moved smoothly in decades. We know how Gelco damper frames seat in those original masonry openings, and we know what to look for when the flue has been through a few earthquake cycles. Every job gets a written price before any work begins, and every repair carries the 365-Day Done Right Promise: a full-year written guarantee, with a free return visit if a covered repair fails. Our technicians arrive background-checked and uniformed. Phones are answered by a live person 24/7. If you own a Gelco fireplace in Pasadena, our techs have likely worked on one just like it this month. We also handle Gelco sales & service across the broader region, so parts procurement runs through channels we use daily.

Common Gelco Chimney Cleaning Problems We Solve in Pasadena
- Warped or rusted Gelco damper frames causing smoke blowback even after a clean flue. We see this often in Pasadena homes near the Arroyo where morning marine-layer humidity lingers. The damper binds, smoke recirculates into the living room, and the homeowner assumes the flue is still dirty. It’s not. It’s the damper.
- Crumbling refractory firebox panels in Gelco prefabricated units. Pasadena’s dry climate means repeated thermal cycling without the moisture cushion that coastal areas get. Panels crack at the mortar joints, and those cracks widen each season. We replace panels with OEM Gelco refractory liners whenever available.
- Deteriorated Gelco cap mesh and loose mounting brackets from Santa Ana wind gusts and nesting pressure. In Pasadena’s Bungalow Heaven and Madison Heights, chimney swifts and squirrels treat an uncapped flue like an open apartment. The mesh tears, brackets loosen, and the cap ends up tilted or hanging by one screw.
- Soot and creosote glaze behind Gelco glass doors when homeowners close the doors too soon after a fire. The glass fogs, the flue walls develop a hard glaze that brushes won’t remove, and the next cleaning requires chemical treatment or mechanical scraping. We tell every Pasadena client: let the fire burn down completely before closing Gelco glass enclosures.
- Damper assemblies that won’t stay open on original Gelco hardware in 1920s and 1930s homes. The cast-iron frames were built for coal firebox dimensions, and years of seismic settling have shifted the masonry enough to bind the pivot points. We rebuild the damper when possible instead of replacing it.
Gelco Service in Pasadena: What Local Conditions Mean for Your Equipment
In Pasadena’s Bungalow Heaven and Madison Heights neighborhoods, many original Gelco dampers lack top-sealing caps, which creates a very specific problem with the city’s chimney swift population. Chimney swifts are a protected species under the Migratory Bird Treaty Act, and once they’re actively nesting in a flue, you cannot remove them or disturb the nest until the young have fledged. That means if swifts move into an open Gelco flue in April, the cleaning and cap replacement has to wait until the birds leave, typically mid to late summer. For Pasadena homeowners, that creates a narrow scheduling window: after fledging but before fall fire season. Our crew tracks this window carefully every year. We schedule Gelco cleanings and cap installs for late July through September in the Bungalow Heaven corridor along Orange Grove Boulevard and the surrounding streets, when the flue is empty and we can install a proper cap with 3/4-inch mesh before the first cool night arrives. The flue either draws or it doesn’t. Let’s find out which.
Gelco Models & Products We Service in Pasadena
We service the full range of Gelco chimney components found in Pasadena homes: masonry fireplace dampers, fireplace doors and glass enclosures, chimney caps and spark arrestors, and firebox panels with refractory liners. When a Gelco damper or cap needs replacement, we use OEM Gelco parts whenever they’re available because the fit matters on older masonry openings. A generic aftermarket damper frame rarely seats correctly in a 1930s firebox throat without gaps. For refractory liners and caps where Gelco parts are discontinued or cost-prohibitive, we recommend quality aftermarket products from HeatShield and Olympia Chimney, always with a repair-first approach on rebuildable dampers and frames. We keep common Pasadena-specific parts in local stock, including Gelco top-mount damper assemblies and stainless caps sized for the narrower flues common in Craftsman homes throughout our Pasadena service area.

A two-story Spanish Colonial in Madison Heights with a steep roof pitch costs more than a single-story Craftsman with a walkable roof. A glaze-coated flue that requires chemical treatment costs more than one with loose soot removal. Every estimate is free, and the written price you approve is the price on the invoice.

FAQs – Gelco Chimney Cleaning in Pasadena
We repair it whenever possible. Most original Gelco cast-iron dampers in Pasadena homes fail because the pivot rods have seized from rust or because masonry settling has thrown the frame out of square. We rebuild the pivot hardware, re-set the frame if needed, and test the operation before we leave. A replacement is only necessary if the frame itself is cracked or corroded through, which happens less often than you’d think. Call (626) 657-5513 and we’ll assess it during the sweep.
Yes. Pasadena’s chimney swift population is active from March through September, and these birds nest exclusively in vertical shafts like uncapped flues. The problem is you often won’t see them. Swifts fly in and out quickly at dawn and dusk, and once nesting begins, you legally cannot remove them until fledging. A Gelco cap with 3/4-inch mesh prevents the birds from ever getting in, and it keeps Santa Ana-driven rain and eucalyptus debris out of your flue. That cap is cheaper than a mid-season exclusion call. Call (626) 657-5513 to get one scheduled before nesting starts.
Once a year if you burn more than a dozen fires per season, every two years if you burn less. Pasadena’s sporadic fire seasons mean some years a Madison Heights flue sees heavy use and other years almost none, but creosote from previous seasons doesn’t just go away. Our Chimney Inspection in Pasadena catches the hidden issues: a rusting damper frame, a cracked firebox panel, or a flue liner that shifted during a small earthquake. Annual is the standard we recommend for any pre-1940 chimney.
Yes, it’s a hazard. Cracked refractory panels expose the metal firebox shell directly to flame, which can lead to heat transfer into the surrounding framing. In Pasadena’s dry conditions, panel cracks also widen with each thermal cycle because the refractory material has no moisture to absorb the expansion stress. We replace cracked panels with OEM Gelco refractory liners when available, and the work carries the full one-year written guarantee. Call (626) 657-5513 for a free inspection.
We can convert Gelco fireplaces to gas log sets or gas inserts, and Pasadena building code has specific venting requirements depending on whether you’re installing vented or vent-free logs. Vented gas logs use the existing flue, but the flue must still be swept and inspected before conversion because gas combustion produces carbon monoxide that needs a clear path. Vent-free gas logs require a chimney damper clamp to keep the flue partially open at all times, and the city requires a CO detector in the room. We walk every Pasadena client through the code specifics during the estimate.
