We provide independent Gelco chimney cleaning and repair across Los Angeles, and we’ve been doing it since 2002.

If your Gelco chimney needs a Los Angeles Chimney Sweep, inspection, or repair anywhere in Los Angeles, we’ll give you a written price before work starts and a written guarantee when it’s done.
Why Los Angeles Residents Choose Us for Gelco Service
Most Los Angeles homes fall into two camps: early 20th-century Craftsman and Spanish Colonial Revival with masonry chimneys, or mid-century ranch and modern builds with prefabricated metal systems like Gelco. We’ve spent years working on both, but Gelco chimneys present their own set of problems. The galvanized outer casings, the double-wall insulation, the caps and dampers. Each model line has weak points, and Southern California’s dry, windy conditions accelerate every one of them.
Nathan Corliss, our owner, grew up in Atwater Village, where older Craftsman bungalows with working fireplaces were just part of the landscape. He learned building systems at LATTC before a seasoned sweep showed him that chimneys are their own discipline entirely. He’s been cleaning and inspecting flues across the LA basin for going on eighteen years, and Nathan has built this company around a simple approach: say the price first, put the promise in writing, and leave the firebox cleaner than you found it. That’s the Kingswell Way, and it’s how every job runs at Ashby Chimney Los Angeles.
We’re part of the Kingswell network of independently owned chimney companies, operating under the Kingswell Guarantee. Every Gelco service call includes a written price before work begins, a written guarantee on completion, and the 365-Day Done Right Promise: if a covered repair fails within the guarantee period, we return and fix it at no charge.

Common Gelco Chimney Cleaning Problems We Solve in Los Angeles
Gelco chimneys are well-built, but they’re not immune to what Los Angeles throws at them. Here are the problems we see most often:
- Glassy creosote buildup in rarely used fireplaces. Los Angeles’ mild Mediterranean climate means most Gelco fireplaces sit unused for months. When creosote sits that long, it hardens into a glassy glaze that standard brushing can’t touch. We use chemical treatments and rotary removal to break it down.
- Rusted galvanized outer casings in hillside fog zones. In neighborhoods like Mount Washington and Laurel Canyon, marine-layer fog settles in and corrodes Gelco’s galvanized casings faster than you’d expect. Once rust-through starts, water leaks into the flue and you’ve got a bigger problem.
- Deteriorated insulation in Gelco Double Wall sections. The layer between the inner and outer walls breaks down over time. When that happens, heat transfers outward and can ignite nearby framing, especially during Santa Ana wind-driven fires when embers are already flying.
- Animal nests blocking Gelco caps. Laurel Canyon and the foothill neighborhoods are ground zero for raccoon and squirrel activity. Unused chimneys become shelter during dry months, and a blocked cap means smoke backs up into the house.
- Warped or corroded inner liners. On older Gelco prefab systems, the inner liner takes years of heat cycling and starts to warp. Once that happens, patching doesn’t make sense. Replacement is the safer, more cost-effective call long-term.
Gelco Service in Los Angeles: What Local Conditions Mean for Your Equipment
Here’s something specific to Los Angeles that doesn’t apply the same way anywhere else: Los Angeles Municipal Code requires that any solid-fuel fireplace in the city be retrofitted or decommissioned unless it’s a registered historic monument. Many Gelco prefab systems in mid-century homes predate these rules, which means homeowners hold onto fireplaces they rarely use, and the chimneys sit for years. When a wildfire scare hits, insurance companies suddenly want inspection reports, and that’s when homeowners discover the creosote hardened into a glaze years ago and the cap has been rusting since the last El Niño. If you own a Gelco chimney in Los Angeles, the smart move is scheduling a Los Angeles Chimney Inspection before an insurer asks for paperwork. Ashby Chimney Los Angeles provides that documentation with photo evidence on every job, so you’re not relying on a technician’s word. Our tech recently pulled a squirrel nest and two feet of hardened creosote from a Gelco AireJet flue in a Laurel Canyon hillside home. The cap was rusted through at the seams. We installed a new stainless cap and treated the creosote with a chemical remover before a rotary sweep. The homeowner had no idea the fireplace was unsafe until a neighbor’s chimney fire prompted the inspection.
Gelco Models & Products We Service in Los Angeles
We service the full Gelco prefabricated chimney lineup including the AireJet, SSII, Double Wall, and Insulated Chimney models. Our parts approach is straightforward: we source genuine Gelco replacement parts for safety-critical components like caps, dampers, and flue sections. For common wear items like gaskets and insulation, we use quality aftermarket equivalents that meet or exceed OEM specs without delaying repairs. We stock common Gelco parts locally for faster Los Angeles turnaround, and we recommend replacement over patching when inner liners are corroded or warped beyond safe use. It’s cheaper long-term than repeated band-aid fixes. For more context on our broader Gelco sales & service capabilities, that page covers the full range.

FAQs – Gelco Chimney Cleaning in Los Angeles
No special cleaning method is required, but the no-burn rules mean your Gelco fireplace probably sits unused for long stretches, and creosote hardens into a glassy glaze during those dormant periods. That glaze requires chemical treatment or rotary removal rather than standard brushing. Call (213) 652-7061 if you haven’t had your Gelco swept in a couple of years and we’ll tell you what it needs.
You can’t tell from the ground. The insulation between the inner and outer walls degrades invisibly, and a Santa Ana wind event can push embers into that gap. The only reliable check is a camera inspection that shows the condition of the flue interior and the cap. We include photo documentation with every Level 2 inspection so you can see what we see. Call (213) 652-7061 to schedule one before the next red flag warning.
Start with replacing the cap if the flue interior is still sound. A rusted cap lets water and animals in, but it doesn’t automatically mean the whole system is compromised. We inspect the flue from top to bottom with a camera before recommending anything. If the inner liner is warped or corroded, we’ll tell you plainly, but we won’t sell you a rebuild you don’t need. Call (213) 652-7061 for a free estimate on cap replacement.
That smoky smell comes from creosote and soot in the flue that absorbs moisture during humid periods, like June gloom or marine-layer mornings. It’s not a fire risk by itself, but it means your Gelco chimney is due for a sweep. A proper cleaning clears the buildup and the smell usually disappears within a day or two. Call (213) 652-7061 and we’ll have it sorted.
In most cases, replacing a cap, damper, or flue section on an existing Gelco chimney does not require a permit under Los Angeles Municipal Code. A full rebuild or structural modification may require one depending on scope. We’ll advise you on what’s needed for your specific situation and document everything for your records. Call (213) 652-7061 with questions, or book a free estimate and we’ll assess it in person.
