Why Oak Hills Residents Choose Us for Gelco Service
Chimney Sweep Apple Valley has swept and serviced Gelco chimneys across the high desert since 2018, and that includes a lot of homes up here on the north slope of the pass. We’re an independent service provider, not authorized or affiliated with Gelco, but the depth of hands-on work we’ve done with Gelco prefab systems, inserts, and caps is why homeowners around Oak Hills keep our number.
Frank Trujillo, our owner, grew up in Apple Valley’s Sitting Bull area and has spent most of his adult life working on chimneys and fireplaces across the High Desert. He learned the mechanical and combustion basics through the HVAC and sheet metal program at Victor Valley College before shifting entirely to chimney work, where the diagnostics side genuinely hooked him. Frank worked in the trade for well over a decade before starting this company, and he’s become the guy neighbors call when a home inspection flags a cracked flue tile or a Level 2 inspection is needed before a sale closes. His daughter still teases him about how much he talks about creosote at the dinner table, but after enough chimney fires, he figures it’s worth the repetition.
We bring professional-grade materials to every job, not whatever ships fastest. We specify brands like DuraFlex and HeatShield because they hold up, and we use quality parts that fit Gelco systems properly. One call covers your chimney and your dryer vent.

Common Gelco Chimney Cleaning Problems We Solve in Oak Hills
- Glazed creosote on Gelco prefab flue walls. Oak and juniper firewood burns hot and resinous, and Oak Hills winter nights routinely drop below freezing. That means heavy burning, which pushes creosote through stage one and stage two into a hard, shiny glaze. A brush-only sweep won’t remove it. We rotary-clean glazed creosote without damaging the flue walls, because a glazed flue is a real chimney-fire risk, not a cosmetic issue.
- Sand and tumbleweed packed into Gelco caps and spark arrestors. Strong sustained winds through the Cajon Pass carry sand and fine dust straight into caps and screens. We’ve pulled fist-sized plugs of debris from Gelco cap screens after a single pass wind event. That restriction kills draft and causes smoke rollout into the room.
- Cracked or spalling firebox brick and mortar joints. Oak Hills sits at roughly 3,000+ feet, and repeated freeze-thaw cycles work on masonry fireboxes all winter. Water gets into small cracks, freezes, expands, and widens them. We repair Gelco masonry fireplace fireboxes before minor spalling becomes a structural problem.
- Rusted or warped Gelco damper blades and cap screens. Wind-driven dust and seasonal moisture eat at metal components over time. A warped damper blade won’t seal, so heated indoor air escapes up the flue all winter. A rusted cap screen lets embers through, which matters during wildfire season here.
- Debris-loaded flues on manufactured homes. A significant share of Oak Hills housing is 1980s-2000s manufactured homes with Gelco prefab metal chimneys. These systems need manufacturer-specific cleaning and inspection, not a generic sweep. We know the difference.
Gelco Service in Oak Hills: What Local Conditions Mean for Your Equipment
Oak Hills sits right on the north slope of the Cajon Pass, so after a strong pass wind event our techs routinely pull sand and tumbleweed fragments out of Gelco caps and fireboxes, a debris load that lower-elevation Inland Empire towns simply don’t see. The same winds that scour the hillsides also blast fine dust through every gap in a chimney system. Combine that with the freeze-driven burning patterns up here, where the fireplace is the primary heat source for many rural homes, and you get a specific kind of wear: glazed creosote on flue walls from hot oak fires, and wind-packed debris in caps and arrestors restricting draft. For Gelco owners specifically, that means cap screens and damper assemblies get more abuse in one Oak Hills season than they would in five years somewhere calmer. If you can see it, we can clean it. If you can’t see it, that’s exactly why the inspection matters.
Gelco Models & Products We Service in Oak Hills
Our crew services the Gelco products we see across Oak Hills homes: prefabricated metal chimney systems on 1980s-2000s manufactured homes, wood-burning fireplace inserts and stoves, multi-flue caps and spark arrestors, and masonry fireplace dampers and firebox assemblies. When a Gelco part needs replacing, we use OEM Gelco parts when the model is still supported and the part is available. For common wear items like dampers and cap screens, we use high-quality aftermarket equivalents that meet or exceed the original spec. We’ll always tell you honestly whether a Gelco chimney or insert is worth repairing or better replaced. No upsell, just a straight answer.

AfterGelco Service Pricing in Oak Hills
Our Gelco chimney cleaning in Oak Hills is priced per job by a written estimate, and the estimate is free. What drives the cost: the condition of the flue, how much glazed creosote has built up, whether the cap or screen needs replacement, and the height and access of the chimney. A standard sweep on a well-maintained Gelco system is straightforward. A system that’s been wind-loaded with debris and burning oak hot all winter may need rotary cleaning and cap work. We walk you through what we found, with camera inspection and a photo report included, before recommending anything. Call (833) 901-6532 for an exact quote. Estimates are free.

FAQs – Gelco Chimney Cleaning in Oak Hills
At least once a year, and more often if you burn oak or juniper regularly through the cold months. Oak Hills winters push heavy burning, and that produces glazed creosote faster than occasional use. If you hear debris rattling after a pass wind event, don’t wait for the annual visit. Call (833) 901-6532 and we’ll get you on the schedule.
Yes. We use rotary cleaning tools sized for the flue, which break up glazed creosote without gouging the flue walls. The key is the right tool and the right speed for Gelco prefab systems, which are more sensitive than masonry chimneys to aggressive cleaning. We inspect as we go.
Because Oak Hills sits on the north slope of the Cajon Pass, and strong sustained winds carry sand, dust, and tumbleweed fragments straight into chimney caps. It’s not a defect in the cap. It’s the local wind load. Regular inspection and cleaning, plus checking screen condition, keeps draft clear. Call (833) 901-6532 for a free estimate.
It depends on the extent of the cracking and the condition of the surrounding masonry. Small cracks from freeze-thaw cycles are often repairable. If the firebox is spalling badly or the structure is compromised, replacement may be the safer call. We’ll show you what we see and give you an honest recommendation. No upsell.
Yes. We service Gelco prefab metal chimneys on manufactured homes, and we know the manufacturer-specific cleaning and inspection requirements these systems need. They’re a different animal than masonry chimneys, and they respond badly to generic sweeping methods. Call (833) 901-6532 for details.
