Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

We provide independent Gelco chimney cleaning, damper repair, and cap replacement across Rossmoor, zip 90720.

Why Rossmoor Residents Choose Us for Gelco Service
We’re the company that closes the loop from inspection to repair. If we’re sweeping your flue and find a failed Gelco damper gasket or a corroded cap, we fix it ourselves. No referral to a second contractor. Nelson Quijada, our owner and lead specialist, grew up working on hillside and mid-century homes in Southern California and has spent two decades focused entirely on flue systems, firebox masonry, and draft diagnostics. When a Rossmoor homeowner calls about a Gelco fireplace that smokes or a chimney cap that’s rusting through, we can usually identify the exact part and the failure mode from the street, because these homes were built with the same fireplace model across entire blocks. You can read more about our Gelco sales & service approach, but the short version is this: we know these components because we repair them constantly.

Common Gelco Chimney Cleaning Problems We Solve in Rossmoor
Here are the Gelco-specific failures we see most often in Rossmoor homes:
- Top-sealing damper gaskets dried out from marine-layer damp. Rossmoor’s coastal air keeps moisture sitting on clay tile liners and damper assemblies for months between fires. The original Gelco gasket shrinks, cracks, and stops sealing. The fireplace smokes on startup, and cold damp air fills the flue.
- Rusted or sagging mesh spark arrestors on Gelco caps. Salt-air exposure eats the galvanized mesh on original caps. The mesh sags, birds get in, and the spark arrestor stops doing its job. We replace it with stainless mesh that holds up in Rossmoor’s climate.
- Corroded Gelco top plates where they meet 60-year-old mortar crowns. The metal plate sits directly on the crown. Over six decades, the crown cracks and the plate corrodes together, letting water track down into the clay tile liner. The identical failure repeats house to house in 90720.
- Gelco glass door sets and insert surrounds loosening at the frame. Older installations shift as the masonry settles. Air leaks around the frame, soot stains the firebox face, and the doors no longer seal when the fireplace is cold.
- Flue blockages caused by a failed damper dumping debris. When a Gelco top-sealing damper fails partially open, leaves, twigs, and bird nesting material fall into the flue. A blocked flue is a fire hazard, and it makes cleaning more urgent than a routine sweep.
Gelco Service in Rossmoor: What Local Conditions Mean for Your Equipment
Rossmoor is a planned community of roughly 2,500 single-story ranch homes built in the early-to-mid 1960s. That matters for Gelco owners because it means your neighbors have the same fireplace. The whole ZIP code shares an aging chimney cohort, and the Gelco dampers, caps, and top plates on these homes are now hitting the 60-year mark together. On a block off Bostonian Drive, our tech opened a Gelco top-sealing damper that had stopped sealing years earlier, letting marine damp sit on the clay tile and rust the frame. We replaced the gasket and linkage, swapped the corroded mesh cap for a stainless unit, and repointed the cracked crown the neighbor’s identical chimney was also showing. The fireplace drafted correctly on the first test fire. That pattern is not a coincidence. It’s what happens when an entire tract community was built with matching fireplaces and the same coastal weather has been working on them since the Kennedy administration. We can often predict your Gelco damper style and cap size from the street, because we’ve serviced the same build on the next block over.
Gelco Models & Products We Service in Rossmoor
We service Gelco top-sealing damper assemblies, Gelco multi-flue caps, Gelco single-flue caps with mesh spark arrestors, and Gelco fireplace inserts and glass door sets. When a part is rebuildable, we repair it. If corrosion has compromised the seal or mounting hardware, we recommend replacement. We match original Gelco dimensions with OEM-equivalent parts where available, and use quality aftermarket stainless caps and top-sealing dampers where the OEM part is discontinued. We’re an independent chimney service, not affiliated with or authorized by Gelco, so our recommendation is based on what your flue actually needs. For customers outside Rossmoor, we provide the same level of detail with Gelco service in Glendora and Gelco service in Walnut.

FAQs – Gelco Chimney Cleaning in Rossmoor
Why do so many Rossmoor chimneys need cap and crown work at the same time?
The crown and cap fail together because they sit on top of each other. When the mortar crown cracks, water intrudes around the cap mounting hardware, the metal corrodes, and the crack widens. Rossmoor’s rare cool-night fires mean these components sit damp for months, so damage accumulates silently. A cap replacement without crown repair often fails within a few seasons. Call (866) 520-4943 and we’ll inspect both.
My Gelco top-sealing damper doesn’t seal and the fireplace smells damp. What’s wrong?
The gasket has almost certainly dried out. Rossmoor’s marine-layer air keeps the damper assembly damp between fires, and after 60 years the rubber loses its flexibility. The damper no longer closes fully, so cold damp flue air drops into the room. This is a rebuild, not a full replacement. We replace the gasket and linkage, and the smell goes away.
Can you match the original Gelco cap on my 1960s Rossmoor fireplace?
Yes, in most cases. We match the original flue tile dimensions and damper size with an OEM-equivalent Gelco cap where available. If the OEM piece is discontinued, we use a quality stainless aftermarket cap matched to the exact dimensions. The mesh is stainless, which holds up far better in Rossmoor’s salt air than the original galvanized material.
Do Rossmoor fireplaces need a Level 1 or Level 2 inspection?
A Level 1 inspection is standard for a routine sweep on a fireplace that has been maintained. If the home changed ownership, the fireplace has not been used in years, or you are seeing water stains or a smoking fireplace, a Level 2 inspection is the right call. Level 2 includes a video scan of the flue interior, which is the only way to see cracked clay tile liners and hidden blockages. We never recommend liner work without camera evidence you can see yourself.
My fireplace smokes. Is it the Gelco damper or a blocked flue?
It is usually one or the other. If the damper gasket has failed, the flue stays cold and the fireplace smokes on startup. If the damper was left partially open for years, debris falls into the flue and creates a blockage. We check the damper first, then run a camera if the flue needs a closer look. Either way, we fix it. Call (866) 520-4943 for an exact diagnosis and a free estimate.
