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 Del Aire, CA | San Bernardino Chimney Sweep
We provide independent Gelco chimney cleaning, inspection, and repair services throughout Del Aire. Most Gelco fireplaces in this 1950s tract-home pocket don’t have heavy creosote buildup; the real problem is airborne soot from LAX and the 405 mixing with bird nesting material at the cap. That’s what blocks the flue and makes fireplaces backdraft on the first cool evening of the year. We clean the full system and fix what’s wrong, and we’re not affiliated with Gelco in any way. Call (877) 516-7159 to book service in Del Aire.

Why Del Aire Residents Choose Us for Gelco Service
We’ve worked on hundreds of Gelco factory-built fireplaces and inserts across the South Bay and LA basin, and that includes plenty of Del Aire homes with the original 1950s masonry or factory-built fireboxes still sitting in the living room. Allen Prescott leads our shop, and he grew up near the Kendall Drive corridor in San Bernardino, so he knows what decades of mild coastal climate, airport dust, and long dry spells do to a chimney. We don’t sell you a replacement firebox because a screen is clogged. We open the unit, tell you exactly what we found, and show you what’s actually serviceable.
Gelco owners in Del Aire call us because we carry OEM Gelco caps, dampers, and screens where they’re still available, matched to the original flue size and termination style. When a part’s been discontinued, we use aftermarket equivalents that fit properly, not whatever’s cheapest on the shelf. We’re a specialist operation: chimney sweeping, chimney repair, and dryer vent cleaning, and nothing else.

Common Gelco Chimney Cleaning Problems We Solve in Del Aire
Here’s what we actually find when we open Gelco units in Del Aire, and why each one happens here more than in most places:
- Spark-arrestor screens packed with nests and gray soot. Year-round mild weather means birds nest in Del Aire chimneys all twelve months. Add the fine particulate that settles from the flight path and freeway, and the screen turns into a felt pad. The flue reads clean inside, but the top is half-blocked, so the fireplace backdrafts on a cool evening.
- Marine-air downdrafts pushing smoke into the living room. The ocean breeze off the coast pushes air down short Gelco stacks, and it’s worse when the original cap is loose or missing its screen. We see this constantly in Del Aire homes where the fireplace only gets lit a handful of times each winter.
- Gelco dampers seized shut from disuse. Infrequent use in the mild coastal climate means dampers sit closed for months or years. Moisture from marine air settles on the cast-iron assembly, and the first winter fire is when the homeowner discovers it won’t open at all.
- Cracked crowns and dried-out cap sealant on 1950s stucco chimneys. Long dry spells shrink and crack the cap sealant, then the first real winter rain leaks down onto the Gelco firebox and flashing. We seal and repair crowns before the water gets a chance to do damage inside.
- Airborne soot and dust accumulating on the firebox and glass. Del Aire sits under the LAX approach and alongside the 405. Roofs here collect a fine gray film that works its way into uncapped or poorly capped flues, coating the glass doors and clogging outside-air inlets on Gelco heat-circulating fireboxes.
Gelco Service in Del Aire: What Local Conditions Mean for Your Equipment
Del Aire is a small unincorporated LA County pocket wedged between LAX and the 405, and that geography shapes how we clean and service Gelco fireplaces here more than almost anything else, much as it does for Gelco service in Lennox. The flight-path and freeway particulate that settles on these 1950s tract roofs mixes with bird nesting debris inside uncapped Gelco flues. On many Del Aire calls, the real blockage is airborne soot and nest material at the cap, not creosote in the firebox. A crew that opens the firebox, sees a clean flue, and calls it done would miss the actual problem sitting on top of the chimney. We start at the cap and work down. On a 1950s single-story stucco tract home near Cerise Avenue, our tech opened a Gelco factory-built fireplace that hadn’t been lit in two winters and found the spark-arrestor screen solid with bird nesting material and fine gray airport-and-freeway soot, while the firebox itself was nearly clean. We pulled the nest and debris, ran a Level 2 camera check on the clay-tile flue, and installed a new screened Gelco-spec cap. The first test fire drafted cleanly with no smoke backup into the living room.
Gelco Models & Products We Service in Del Aire
We service the Gelco factory-built fireplaces most common in 1960s through 1980s tract installations, including builder-grade units with metal chases and louvered grilles, heat-circulating metal fireboxes with glass bi-fold doors and outside-air kits, and gas log sets or gas inserts converted into original masonry fireboxes. We also handle multi-flue caps and spark-arrestor screen assemblies on exterior stacks. When we work on a Gelco unit in Del Aire, we fit OEM caps, dampers, and screens where they’re still available, and use quality aftermarket equivalents when OEM parts are discontinued, always matching the flue size and termination style. We stock the common parts locally so we don’t have to wait two weeks for a cap before finishing a Del Aire job.

FAQs – Gelco Chimney Cleaning in Del Aire
Because the cap screen is almost certainly clogged with a mix of bird nesting material and fine soot from LAX and the 405. The firebox and lower flue often read clean, but the top is blocked, so the smoke has nowhere to go and drafts back into the living room. We clean the full system, install or repair the cap screen, and the first test fire usually drafts cleanly.
If the insert was already in the home when you bought it, or it’s been more than a couple of years since anyone looked at the flue, yes. A Level 2 camera inspection shows you the condition of the clay-tile liner, the flue collar, and the interior of the firebox, which matters here because Del Aire’s long dry spells can crack old clay tiles without anyone noticing. Call for a free estimate.
We remove the nest, but we also check the cap screen and the flue condition while we’re up there. In Del Aire, birds nest year-round because the weather stays mild, and a nest pulled without fixing a damaged screen just gets rebuilt next season. We clean the flue, repair or replace the screen, and make sure the termination is sealed so the next nesting attempt doesn’t start another blockage.
Usually a repair. Seized Gelco dampers are common in Del Aire because the fireplace sits unused for long stretches, and marine air from the coast works on the cast-iron assembly. We free and lubricate the damper when the assembly is intact, and replace it when the linkage or blade is rusted through. We’ll tell you which one you have before we do anything, and the estimate is free at (877) 516-7159.
We seal and repair the crown with an elastomeric bond that holds through wet winters and dry summers, and we check the cap sealant and flashing in the same visit. Del Aire goes months without real rain, then gets hit with concentrated winter storms, so a cracked crown has plenty of time to leak before anyone notices. Call (877) 516-7159 and we’ll inspect the crown, cap, and flashing before the next storm arrives.
