Gelco Chimney Cleaning in South Pasadena, CA | Hickory Chimney Sweep
We clean and service Gelco fireplaces, inserts, dampers, and caps throughout South Pasadena, including the 91030 and 91031 ZIP codes, and also offer Pasadena Gelco service nearby. Most of our work here happens on century-old Craftsman and Spanish Colonial homes where the chimney itself is often as protected as the furniture inside. We’re independent of Gelco, but we know these units inside and out. Call us at (855) 554-2841 when your Gelco insert starts acting up or your damper won’t budge.
Why South Pasadena Residents Choose Us for Gelco Service
Nobody in South Pasadena has a cookie-cutter fireplace. Nearly every chimney we touch sits on a 1920s bungalow or a Spanish Colonial Revival with original clay tile flues and decorative brick surrounds that have been baking under the San Gabriel Valley sun for a hundred years. Gelco inserts and dampers installed in these older fireplaces fail differently than they do in newer construction, and that’s what we understand — whether we’re working in South Pasadena or providing San Marino Gelco service.
Ruben Acosta, our owner, spent two-plus decades sweeping and inspecting chimneys across East Los Angeles and the surrounding neighborhoods. He learned duct and flue work at East Los Angeles College, where an instructor told him the real job security was in chimneys nobody else wanted to touch. He was right. We’ve carried that lesson into every historic district in South Pasadena.
We stock OEM Gelco parts for dampers, blower assemblies, and critical components. When a part is discontinued or the OEM price doesn’t make sense, we’ll tell you and use a quality aftermarket equivalent. You always know which one you’re getting.

Common Gelco Chimney Cleaning Problems We Solve in South Pasadena
- Seized or warped Gelco damper assemblies. South Pasadena chimneys get used maybe fifteen or twenty times a year, mostly on cool winter evenings and holidays. That light, intermittent use lets creosote and debris collect around the damper linkage. When the mechanism sits unused through the long dry season, it seizes. We disassemble, clean, and lubricate, or install an OEM Gelco replacement when the old one is too far gone.
- Premature Gelco insert fan and blower failures. Many of these original fireboxes are oversized. A Gelco insert pushed into a large, shallower historic hearth often lacks proper clearance around the blower assembly. Heat builds up, bearings wear out, and the fan quits mid-season. We see this pattern repeatedly in the Craftsman homes around the Raymond Hill district.
- Corroded and clogged Gelco cap screens and louvers. Santa Ana winds push leaves, twigs, and bird nests down flues that sit dormant most of the year. Debris builds up on cap screens, moisture from the dry-season fog lingers, and metal corrodes. The draft gets restricted, smoke backs up into the living room, and the cap fails. We clean or replace Gelco multi-flue caps with materials that can handle South Pasadena’s dry heat.
- Degraded Gelco insert gaskets and seals. The dry Mediterranean climate plus repeated heating and cooling cycles breaks down gasket material faster than you’d expect. When a seal fails on a tightly built historic home, you’ll notice creosote odors even when the fireplace hasn’t been used in weeks. We replace these gaskets and seal assemblies routinely.
- Shifted or cracked clay flue tiles behind Gelco inserts. A century of settling and the occasional earthquake shifts the original flue liner. When we pull a Gelco insert out for cleaning, we often find cracked or misaligned clay tiles behind it. That’s not just a cleaning problem. It’s a fire-safety issue, and it’s why we recommend a Level 2 inspection whenever we’re already inside the firebox.
Gelco Service in South Pasadena: What Local Conditions Mean for Your Equipment
Here’s something that doesn’t show up on a generic service page. South Pasadena enforces strict historic preservation rules, especially in designated districts like the Mission Street area and Raymond Hill. That means when a Gelco insert, damper, or chimney cap needs replacing, we can’t just install any modern component that changes the visible facade or roofline. The solution has to read as original. So when a Gelco multi-flue cap fails on a 1920s Spanish Colonial near Mission Street, we don’t grab a standard galvanized replacement off the truck. We fabricate a period-correct cap in a finish that matches the home’s clay tile roofline. Same with dampers: we repair or replace them from inside the firebox so the exterior brick and decorative surround stay exactly as they were. No other city in the San Gabriel Valley puts the same constraint on simple fireplace maintenance, though we do similar San Gabriel Gelco service for historic homes there. If you own a Gelco-equipped fireplace in South Pasadena, this affects your repair options whether you knew it or not.
Gelco Models & Products We Service in South Pasadena
We service Gelco direct-vent gas fireplace inserts, wood-burning fireplace inserts, fireplace dampers, and multi-flue chimney caps. When a critical component like a damper assembly or blower fails, we source OEM Gelco parts first. For non-critical hardware like cap screens or louver covers, we’ll use quality aftermarket equivalents when OEM is discontinued or priced without justification. We keep common Gelco-compatible damper hardware, gasket material, and cap components stocked for fast turnaround in South Pasadena. You won’t wait a week while a part ships from the manufacturer.

AfterGelco Service Pricing in South Pasadena
A Gelco chimney cleaning in South Pasadena typically runs between $180 and $350. That covers a full sweep, a visual inspection of the insert and venting, and a report with photos. Damper repairs start around $150 and up depending on whether the part is OEM Gelco or aftermarket. A full Level 2 inspection, which we recommend for real estate transactions or any time we find questionable flue tile, runs $250 to $500. Cap replacement costs vary widely because historic preservation rules often require custom fabrication. Here’s the straight answer: we don’t quote over the phone without seeing the chimney. But every estimate is free, and you’ll see photos of what we found before anyone asks for a signature. Call (855) 554-2841 to schedule.

FAQs – Gelco Chimney Cleaning in South Pasadena
Yes. We perform damper repairs and replacements from inside the firebox, so the visible brick, tile, and decorative surround remain untouched. This matters in South Pasadena’s designated historic districts, where exterior alterations can trigger a preservation review. We use OEM Gelco damper replacements whenever possible to keep the fit and function original.
The best cap is one that functions well and doesn’t look like it was bolted on yesterday. For most historic homes in South Pasadena, that means a custom fabricated cap matched to the home’s original clay tile or masonry roofline. Standard galvanized caps often fail aesthetic review in districts like Mission Street. Functionally, the cap needs to keep out Santa Ana wind-blown debris and bird nests while maintaining proper draft for your Gelco insert. Call us at (855) 554-2841 and we’ll tell you what your specific chimney needs.
Annually. Even though South Pasadena homeowners use their fireplaces lightly and mostly in winter, the dry air and summer heat cause brick and mortar to crack, and dormant flues collect debris from Santa Ana winds. A yearly inspection catches shifted clay tile, degraded gaskets, and damper seizing before they become safety problems. If you use your Gelco insert heavily during the winter, consider a mid-season check as well.
Yes, but it requires care. Many South Pasadena Craftsman fireboxes are smaller or more shallow than what modern inserts were designed for. Poor clearance causes the overheating and bearing wear that kills blowers prematurely. We can replace the blower assembly with an OEM Gelco part and, where possible, adjust the insert’s position or ventilation to improve airflow. If replacement doesn’t make sense given the firebox dimensions, we’ll tell you that too.
Yes, we perform Level 2 inspections for real estate transactions throughout South Pasadena and the surrounding area. These are more thorough than a standard sweep: we camera the flue, check the Gelco insert’s condition, verify damper function, and document everything with photos. South Pasadena’s older housing stock makes these inspections particularly important. Call (855) 554-2841 for scheduling and current pricing.
