Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Alcott Chimney Sweep Is Highland’s Preferred Gas Fireplace Repair Company
Highland homeowners keep calling us because we show our work. Ruben Castellano built Alcott Chimney Sweep on a simple rule: nothing gets recommended unless you can see the problem yourself on camera. That matters in Highland, where 1950s – 1970s ranch homes along Base Line Street and Fifth Street are loaded with original clay-tile flues. Those flues crack. They crack from decades of heat cycling, from Santa Ana-driven reverse draw, and from creosote loading that happens faster here than almost anywhere else in the Inland Empire. Other companies hand you a five-thousand-dollar quote and a vague warning about safety. We run the camera, put the cracked tile on screen, and let you watch. If the repair is genuinely needed, you’ll see why. If it can wait, we’ll tell you that too and document it.
Before any Alcott technician rings your doorbell in Highland, you’ll know their name and see their photo. It’s the Threshold Standard, not an optional add-on: background-checked, identity-verified, uniformed, and announced before arrival. When they arrive, they’ll show a photo ID badge. No exceptions, every time. That’s the kind of predictability Highland homeowners tell us they want. You’re not opening the door to a stranger. You’re opening it to the person we sent you a picture of.
Every repair we do in Highland carries a written guarantee. If that repair fails within 365 days, the second visit is free. That’s the 365-Day Done Right Promise, and it’s included on every job. No fine print about exclusions. No “well, that’s a different part.” It’s a full year of accountability, in writing, and it applies to every gas fireplace repair we perform from San Bernardino across to Redlands and up through the Highland foothills.

Our Gas Fireplace Repair Services in Highland
Gas Fireplace Repair
We repair gas log sets, standing pilot systems, electronic ignition, thermocouples, thermopiles, valves, and gas supply lines in Highland homes. Many of the gas fireplace failures we see in Highland aren’t actually in the gas system at all. They’re in the chimney stack behind the firebox. A gas log set burning in a 1960s masonry firebox with an unlined or clay-tile flue is venting into a chimney that was never designed for that appliance. That’s a critical distinction, and it’s why our Gas Fireplace Repair process always starts with a visual check of the entire venting path. If the firebox is fine but the flue isn’t, we fix the actual problem, not the symptom. Gas logs are also affected by Highland’s high fire hazard zone: any unit within a wildland-adjacent area should have a functional, code-compliant spark arrestor and a clean flue. We’ll verify both.

Level 2 Camera Inspection
You can’t see a cracked flue liner by looking up from your living room. You need an articulating camera pushed through the full flue length, and that’s exactly what a Level 2 inspection is. In Highland, we strongly recommend a Chimney Inspection in Highland - specifically a Level 2 camera inspection - before your gas fireplace’s first allowed burn day of the season – especially if your home sits along Base Line Street, Fifth Street, or in any of the foothill subdivisions built before 2000. These inspections take about 45 to 90 minutes, and you watch the footage in real time on our screen. You’ll know if your clay tile liner is cracked, if your flue has a third-degree creosote glaze, or if your gas logs are venting into a void in the chimney chase. You get a written report with still photos. No vague warnings. Just documented, visual evidence.

Flue Liner Replacement
Highland’s 1950s – 1970s ranch homes often have original clay-tile flue liners that have never been touched. Repeated heat cycles – freezing nights, hot Santa Ana days, and the on-off pattern of gas log use – cause hairline fractures. Once cracked, combustion gases leak into the voids between the tile and the chimney chase. That’s a carbon monoxide risk and a fire risk, and it’s invisible without a camera. When we find cracked tile in a Highland home, we resleeve with HeatShield or a professional-grade replacement liner, and we never recommend the work without showing you the crack on camera first. A properly lined flue also handles the reverse-draft conditions we see under Cajon Pass winds far better than bare masonry.

Chimney Caps, Spark Arrestors, and Damper Repair
Santa Ana winds blow hard through the Cajon Pass corridor northwest of Highland. Those winds throw debris, tear off weak caps, and create negative pressure that pulls combustion byproducts back into your living room. A damaged cap or missing spark arrestor also lets birds and rain in, which leads to blocked flues and spalling in the firebox. We inspect, replace, and repair caps, dampers, and top-sealing systems on gas fireplaces throughout Highland. It’s a small fix that prevents a much larger problem.

Trusted Brands We Service in Highland
We service and install gas fireplaces and components from the brands chimney professionals specify, not box-store substitutes. That includes Famco dampers, Copperfield fireplaces, DuraFlex liner systems, and HeatShield resurfacing. When a Highland homeowner has a failing damper on a 1970s ranch, we install a Famco replacement. When a gas insert needs a new flue path, we line with DuraFlex and address the firebox properly. We carry these parts locally, which means faster turnaround for our Highland customers. You’re not waiting on a special order from across the country. We bring what we need to the job.
Common Gas Fireplace Repair Problems We See in Highland Homes
- Cracked clay-tile flues in 1950s – 70s ranch homes. Base Line Street and Fifth Street corridors are full of original clay-tile flues that have heat-cycled for 50-plus years. Hairline cracks develop, and gas log combustion gases escape into the chimney chase. We confirm with camera footage before anything is recommended.
- Reverse-draw smoke spills under Santa Ana conditions. Cajon Pass winds funnel powerfully into Highland from the northwest, creating pressure differentials that push combustion byproducts back into living spaces. A worn damper, a capped-but-leaky flue, or missing top cap makes this dramatically worse.
- Damaged caps and spark arrestors from wind-blown debris. Highland sits in a CAL FIRE-designated High Fire Hazard Severity Zone. A damaged spark arrestor is a life-safety issue, not just maintenance. Wind-blown debris also knocks caps loose, letting rain and birds in, which blocks flues and causes fireside spalling.
- Creosote-glazed flues from compressed burn days. South Coast AQMD no-burn days push all of Highland’s allowed fireplace use into a small number of winter burn days. When the curtailment lifts, everyone lights up at once – often in a flue loaded with creosote from last season. That creates a disproportionate share of Highland’s chimney incidents. It’s also why we tell customers to call us before the first allowed burn day, not after.

FAQs – Gas Fireplace Repair in Highland
For a 1960s masonry fireplace with gas logs in Highland, you need a Level 2 camera inspection, not a Level 1. A Level 1 is a visual check of accessible areas and is fine when nothing has changed. But a gas log set in an original clay-tile flue has almost certainly heat-cycled that tile for decades, and a Level 2 is the only way to see hairline cracks, creosote glazing, or voids behind the tile. We recommend a Level 2 before your first burn of the season, especially if your home is along Base Line Street or Fifth Street. Call (336) 863-3889 to schedule one – we’ll show you the footage live.
That smoke smell during Santa Ana events is almost always reverse draw, and it’s common in Highland because of the Cajon Pass funnel effect. High winds push air down your chimney instead of letting combustion gases rise, forcing them back into the living space. A worn damper, a cracked flue, or a missing cap makes it much worse. Repairing or replacing the damper and addressing any flue damage usually fixes it. We can pinpoint the cause with a camera inspection. Call (336) 863-3889 and we’ll get a technician to your Highland home.
No. South Coast AQMD mandatory no-burn curtailments apply to gas log sets as well as traditional wood fires in Highland, even though gas logs produce less particulate matter. When a curtailment day is declared, you cannot legally burn wood or manufactured logs in your gas fireplace. The practical problem is that many Highland homeowners still run their logs anyway, or they don’t realize the restriction applies to them – and a gas fireplace with a cracked liner or creosote-glazed flue is dangerous regardless of legality. If you’re unsure about your fireplace’s condition before the next allowed burn window, get a camera inspection. Call (336) 863-3889 for an appointment in Highland.
You can’t tell from the outside. A cracked clay tile liner in a Highland chimney shows no visible symptom from the living room – no smoke stain, no odor, no sound. The only way to know is to run a camera through the flue. That’s exactly what our Level 2 inspection does. In a 1960s ranch home on Base Line Street, we recently pulled a failing gas log set out and found the original clay liner cracked from years of heat-cycling, with third-degree creosote glazing the upper flue. The homeowner had no idea anything was wrong. We showed them the footage on screen and installed a HeatShield liner. No upselling. Just evidence. The lesson: don’t burn before you’ve been checked. Call (336) 863-3889 and we’ll schedule a camera inspection in Highland.
1980s zero-clearance fireplaces use prefabricated metal fireboxes and flue liners that fatigue faster under Highland’s temperature swings. The metal expands and contracts with the cold foothill nights and hot Santa Ana days, and after 35 to 45 years, seams can separate, the refractory panels can crack, and the flue liner can warp. Gas log sets run at high temperatures, which accelerates that wear. The repair isn’t about the gas valve – it’s about the metal components that contain the fire and vent the gases. We inspect and repair these units in Highland regularly. If your zero-clearance is from the ’80s and hasn’t been looked at in years, call (336) 863-3889. A camera inspection tells the story.
