Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Gelco Chimney Cleaning in Kensington, CA
We provide independent Gelco chimney service across Kensington, and the one thing that sets our Gelco work here apart is the cap. In a hillside town where eucalyptus leaves and seed pods settle on every roof, a Gelco cap and its spark arrestor screen take more punishment than the flue behind them, so our sweep is built around clearing, checking and restoring that cap as carefully as we sweep the sections. We’re an independent shop: not affiliated with Gelco, not authorized by the manufacturer, just a company that has worked on these assemblies often enough to know where they fail. Our technicians have up to 13 years of experience. Call (866) 361-9755 for a free estimate.
Why Kensington Residents Choose Us for Gelco Service
Gelco factory-built fireplaces and chimney systems reward careful work. The sections fit tightly, the caps are matched to the flue, and none of it tolerates a sloppy install or a rusted upper joint left alone. That’s the kind of assembly we know well, and it’s why Kensington homeowners call us when something feels off with draft, smell or the cap mesh.
We supply and install professional-grade components from brands the trade specifies: DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco and Copperfield. When a Gelco cap screen or section needs replacing, we match it with manufacturer-specified or genuinely equivalent UL-listed parts instead of a generic cap that’s the wrong diameter for the flue.
Scheduling is straightforward. We book a sweep, show up when we say, and walk you through what we found so you can decide with the facts in hand. One company handles the sweep, the inspection and the repair, which means no hand-off to a second contractor when the diagnosis turns up something that needs fixing. Written estimates set the price before any work begins.

Common Gelco Chimney Cleaning Problems We Solve in Kensington
These are the issues we run into again and again on Gelco systems in Kensington, and each one tends to trace back to the same handful of local causes:
- Cap mesh packed with eucalyptus debris. Leaves, seed pods and fine twigs mat the spark arrestor and the crown edge of a Gelco cap after a wet winter. Draft drops, moisture sits against the metal, and the fire smokes on startup. Clearing the mesh is half the job.
- Rust at upper joints and the cap crimp. Galvanized Gelco sections pit where runoff and roof litter collect, especially on shaded chimneys facing north. That rust is easy to miss from the ground and easy to catch on a Level 2 inspection.
- Detached or corroded cap screens. A screen that’s lost its fastening or corroded through leaves the flue open to debris and birds, and it weakens the spark control that matters most during a dry Kensington summer.
- Metal-to-masonry transitions losing their seal. Where Gelco connector pipe meets masonry at the thimble or attic penetration, sealant dries and gaps appear, letting creosote-laden smoke seep into the structure.
- Creosote loading in heavily used fireplaces. Kensington’s mild, damp winters mean fireplaces run hard for months. Creosote builds on the sections and on the cap alike, and both need to come clean.
Gelco Service in Kensington: What Local Conditions Mean for Your Equipment
Kensington sits on steep, wooded hillside above Berkeley, and the mature eucalyptus, oak and pine canopy here does something specific to a Gelco cap: it fills it. After a winter storm, leaves and seed pods routinely pack the spark arrestor mesh and smear the crown edge, and once that debris is soaked and sitting against metal, it holds moisture where runoff already collects. On the narrow winding lanes off Arlington Avenue, we see this on shaded chimneys far more than on open ones, and the same debris that smothers the screen can carry creosote residue into the dry months. That’s why we treat the cap as part of the fire-defense picture here. Clearing the mesh and confirming the spark arrestor is intact isn’t a finishing touch on a Kensington sweep. It’s one of the reasons the sweep happens.
Gelco Models & Products We Service in Kensington
We work on Gelco prefabricated metal fireplace and chimney systems, including factory-built units common to mid-century and rebuilt fireplaces. That covers the multi-flue caps and spark arrestor screens, the UL-listed chimney sections and connector pipe used in retrofits, and the joints and transitions where those parts meet the house.
Choosing parts is where a Gelco system either stays sound or drifts out of spec. We match the original cap, screen and section components with manufacturer-specified or genuinely equivalent UL-listed parts, never a generic cap that’s the wrong size for the flue. When rust has compromised a section, we’ll tell you plainly and replace that section rather than recoat it. When the assembly is still sound, a sweep, a cap replacement and a fresh seal will serve it well. We’re an independent Gelco service provider, not manufacturer-affiliated or authorized.

AfterGelco Service Pricing in Kensington
Every job is priced per job by a written estimate, and the estimate is free. What drives the number is what your Gelco system actually needs: a straightforward sweep and cap clear sits at the low end, while a Level 2 inspection with camera work, a cap replacement, a section swap or re-sealing at the thimble and attic penetration adds to it. Height, roof access on a steep Kensington lot and how much debris has packed the screen all factor in. The range is confirmed in writing before we start, and the written estimate sets the final price. If the work can safely wait until next season, we’ll say so. Call (866) 361-9755 for an exact quote; estimates are free.

FAQs – Gelco Chimney Cleaning in Kensington
Because of the trees. Kensington’s heavy eucalyptus canopy sheds leaves and seed pods that routinely cap and smother chimney screens after winter storms, and the mesh on a Gelco spark arrestor catches them efficiently. A screen that’s matted blocks draft and holds moisture against the metal, so clearing it is part of the annual sweep here, not an optional extra. Call (866) 361-9755 to book a sweep and cap clear.
Yes. A factory-built Gelco system has metal sections, joints and a matched cap that a Level 2 inspection with camera work is designed to evaluate, and that’s the level we recommend when there’s been a storm, a repair or a change to the system. A masonry fireplace gets checked for cracked flue tile; a Gelco assembly gets checked for rust, loose joints and a failing screen. Call (866) 361-9755 for an estimate.
It depends on how far the rust has gone. Surface corrosion at a cap crimp or upper joint can often be cleaned, re-sealed and monitored, but rust-through on a section means that section should be replaced rather than recoated. We’ll show you what we found and explain which case you’re in before any work is agreed. Call (866) 361-9755 for a free estimate.
Creosote is fuel, and a compromised spark arrestor lets embers past the cap. In a hillside enclave surrounded by tinder-dry summer vegetation, an intact screen and a clean flue both matter – the debris packed against a Gelco cap can carry creosote residue into the dry months, which is why we treat spark control as a fire-defense habit here, not just an indoor air quality concern. Call (866) 361-9755 to schedule a sweep.
A blocked or matted cap screen is the usual cause, followed by a cold flue that hasn’t warmed enough to draw. In a hillside Kensington home with a Gelco factory-built fireplace, the typical call follows a wet winter: draft is weak, the firebox smells smoky on startup, and the cap mesh is packed with eucalyptus leaves and seed pods. A qualified local pro inspects the flue and cap, clears the debris, sweeps creosote from the sections, checks the screen and upper joints for rust, and re-seals or replaces worn components. Call (866) 361-9755 for an estimate.
