Gelco Chimney Cleaning in Van Nuys, CA | San Bernardino Chimney Sweep
We service and clean Gelco fireplaces, inserts, and venting systems throughout Van Nuys, and we also offer Chimney Sweep – Van Nuys service. The one thing that makes our Gelco work different here is what we find behind the firebox: original 1950s clay-tile flues that shift and crack as Valley soil settles under the footing. If you own a Gelco unit in a postwar tract home, call us at (877) 516-7159 before you light the first fire of the season. We’ll camera the flue, clean what needs cleaning, and fix what needs fixing.

We’re Gelco sales & service specialists by trade, not by factory badge. San Bernardino Chimney Sweep is an independent crew that works on Gelco equipment every week across the San Fernando Valley. We know these units and we know this city’s chimneys. That combination matters more than any authorization sticker.
Why Van Nuys Residents Choose Us for Gelco Service
Allen Prescott, our owner, grew up in San Bernardino and spent the better part of three decades working on chimneys that have seen everything the Southern California climate can throw at them. He built our reputation on straight talk: we tell you what’s inside your flue, why it matters, and what actually needs doing versus what can wait. That’s why homeowners across Van Nuys service area call us when their Gelco fireplace misbehaves.
We’re not a handyman service moonlighting in chimney work. We sweep, we repair, and we clean dryer vents. When our camera finds cracked tile or a seized damper, we don’t hand you a phone number for another company. We fix it. And we use contractor-grade materials from Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield because hardware-store substitutes fail in ways that cost more later.

Common Gelco Chimney Cleaning Problems We Solve in Van Nuys
Here’s what we find when homeowners in Van Nuys call us about a Gelco unit:
- Cracked and shifted clay-tile flues. The original flues behind Gelco fireboxes in 91401, 91405, and 91406 tract homes crack and lose mortar joints as the soil shifts and the stack heat-cycles. A camera check often shows gaps the homeowner never sees from the hearth. We repoint those joints and seal them before they become a fire path.
- Seized dampers and rusted damper frames. A Gelco fireplace that sat unused from April through November won’t open cleanly on the first cold snap. Long idle summers let moisture and corrosion do their work. We free or replace the assembly so the fire actually draws.
- Clogged and failing Gelco caps. Years of Valley UV and Santa Ana grit pack cap screens with wind-driven debris. Birds get in. Draft reverses and smoke pushes back into the living room on windy nights. We install new Gelco-spec caps and multi-flue assemblies that actually hold up to Van Nuys conditions.
- First-light failures on gas inserts and log sets. On lightly-used Gelco gas units, the failure is rarely creosote. It’s dried-out gaskets, pilot assemblies, or bird nest debris in the vent termination. We check the whole vent run, not just the box.
- Smoke spillage from wind-driven downdrafts. The Valley’s notorious wind events hit older tract blocks especially hard. If your Gelco fireplace smokes only on windy nights, the problem is usually cap or flue height, not the firebox. We diagnose it with a camera and fix the right thing.
Gelco Service in Van Nuys: What Local Conditions Mean for Your Equipment
In the older tract blocks off Van Nuys Boulevard, the original 1950s clay-tile flues have a pattern we don’t see nearly as often in slab-on-grade subdivisions. The Valley’s expansive soil shifts under the chimney footing, and decades of heating-and-cooling cycles crack the tile and open mortar joints. A Gelco insert bolted into one of these old ranch fireplaces might burn fine for years while the flue behind it slowly comes apart. That’s why we push a camera inspection before the first cold snap, not after smoke fills the house. Allen Prescott’s rule: a clean flue isn’t a luxury. It’s just how you keep the fire where it belongs. On a block off Van Nuys Boulevard in 91405, we pulled a Gelco wood-burning insert from a 1950s ranch fireplace and found the original clay-tile flue missing mortar joints at two courses, exactly where the soil under the stack had settled—similar to what we see during Gelco service in North Hills. We camera-inspected the full run, cleared packed leaf litter and a starling nest off the cap screen, then repointed the joints and set a new Gelco-spec cap so the homeowner could burn on the first cold night without downdrafting smoke into the living room. That’s a typical Van Nuys Gelco job for us.
Gelco Models & Products We Service in Van Nuys
We work on Gelco factory-built wood-burning fireplaces, the metal-firebox units common in postwar Valley tract homes, and we also handle Gelco repair in Encino. We service Gelco gas log sets and vented gas fireplace inserts. We handle Gelco wood-burning inserts, chimney caps, and multi-flue cap assemblies. Where genuine Gelco parts are still available, we use them: caps, damper assemblies, gaskets. For standard items like flue tile, mortar, and crown coating, we use quality aftermarket materials when the OEM part is discontinued or priced unreasonably. We’ll tell you honestly when a 1950s firebox just needs sealing and capping versus when the Gelco insert itself has reached the end of its service life. No upsell, no scare tactics.

AfterGelco Service Pricing in Van Nuys
A standard Gelco chimney cleaning and inspection in Van Nuys typically runs between $180 and $340 depending on flue condition, cap access, and whether it’s a wood-burning or gas unit. A Level 2 camera inspection, which we recommend for any postwar tract home with original clay tile, adds to the job because it takes real time and gives you photographic evidence of what’s happening back there. Cap installation runs $150 to $450 depending on the cap size and roof access. Mortar repointing, when our camera finds joints gone in a 1950s flue, starts around $500 and goes up with the number of courses involved. Our free estimate includes the camera look and a written breakdown, so you know exactly what you’re paying for before we start. Call (877) 516-7159 for a quote on your specific setup.

FAQs – Gelco Chimney Cleaning in Van Nuys
Yes. If your home sits in one of the older tract blocks built on shifting Valley soil, the original clay-tile flue behind your Gelco firebox has almost certainly moved since it was installed. We camera every flue before the first burn. It’s the difference between catching cracked joints early and finding them after smoke or fire has already found a way out. Call (877) 516-7159 to schedule a look.
Wind-driven downdrafts in Van Nuys are almost always a cap or termination problem. Santa Ana winds pack screens with debris, birds get in, and a damaged cap can’t keep the draft moving up. We inspect the cap assembly and the top of the flue first. Often a new Gelco-spec cap solves it entirely. If it doesn’t, we check flue height and interior obstruction before touching anything else.
We check the pilot assembly, thermocouple, gaskets, and the full vent run from the firebox to the termination. Bird nests, dried-out gaskets, and corroded pilots are the usual culprits on long-idle gas units. We clean the burner, test the safety shutoffs, and camera the vent to make sure it’s clear. If it’s repairable, we repair. If the unit is done, we tell you straight.
In most Van Nuys tract homes, yes. Repointing removes the failed mortar and replaces it course by course. It’s the right fix when the brick itself is still solid and the cracks are limited to the joints. We’ll show you the camera footage first so you can see exactly what we’re proposing and why. Rebuilding is a last resort, not a first recommendation.
Once a year, before the first real cold snap. Light use doesn’t mean no creosote. The Valley’s idle months let whatever is in the flue harden and glaze, and a glazed creosote layer is harder to remove and more dangerous than fresh buildup. An annual sweep and inspection catches it early. It’s cheaper than a flue fire. Call (877) 516-7159 to get on the schedule.
