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 Madera’s Preferred Gas Fireplace Repair Company
We’ve earned a strong reputation around Madera by doing something most chimney companies won’t: showing you the problem on camera before we ask you to spend a dime on a fix. Ruben Castellano built Alcott Chimney Sweep on the idea that a homeowner who can see the cracked liner or corroded damper with their own eyes doesn’t need a sales pitch. They need a repair.
Every technician we send to Madera arrives background-checked and identity-verified under the Threshold Standard. You’ll know the technician’s name and see their photo before we arrive, and they’ll show a photo ID badge at the door. Every time. No exceptions. If you’re home alone or have young kids, that’s not a convenience. It’s the whole point.
Our Gas Fireplace Repair team also carries professional trade materials on the truck – HeatShield, Gelco, Olympia Chimney, and Famco – so we’re not sending someone back to the shop for parts mid-job. And every repair comes with a written guarantee. If it fails within the coverage period, the second visit is free. That’s our 365-Day Done Right Promise, and it’s included on every job, not sold as an upgrade.
Our Gas Fireplace Repair Services in Madera
Gas Fireplace and Insert Inspection with Camera-Documented Findings
In Madera, we bring the inspection camera to every gas fireplace call because what the flue looks like on the inside almost never matches how often the homeowner says they burn. You get to watch the camera feed live. We don’t describe a problem we won’t show you. A Level 2 camera inspection typically runs $160 to $260 in Madera, and if we find something that needs repair, that inspection cost is often credited toward the work.
Flue Liner Repair and Relining for Gas-Vented Masonry Stacks
This is the repair we do most often in Madera’s older in-town neighborhoods. Homes built in the 1940s through 1960s near downtown have clay-tile flues that were sized for open wood fires, not sealed gas inserts. When those inserts vent into the oversized original flue, exhaust cools and condenses before it clears the stack. That corrodes the tile, spreads moisture into the surrounding masonry, and can push carbon monoxide back into the house. Relining with a HeatShield-applied liner sized for the gas appliance typically runs $2,400 to $4,800 in Madera depending on flue length and access. We’ll show you the camera footage first, and if the existing liner is actually fine, we’ll tell you that too and send you on your way.
Damper and Smoke Chamber Repair on Original Madera Masonry Fireboxes
Madera’s older stucco homes with original brick fireboxes have spent decades cycling through Central Valley heat and winter fog. Mortar joints deteriorate. Brick spalls. Dampers rust open or seize shut. When you have a gas log set venting through that firebox, a rusted-open damper sends warm house air up the flue all winter long, and a corroded damper assembly can trap moisture in the smoke chamber. Damper repair in Madera ranges from $180 to $420 for a replacement top-mount damper to $600 to $1,400 if the smoke chamber needs parging. We’ll show you the condition of the chamber on camera before we quote anything.
Gas Log Set and Pilot Assembly Repair
In Madera’s 1990s and 2000s tract-home subdivisions, most gas fireplaces are factory-built zero-clearance units with gas log sets. Common failures here include dirty thermocouples, failed pilot assemblies, clogged burner ports from Valley dust, and control valves that won’t hold. Parts and labor for these repairs in Madera typically fall between $140 and $380. If the unit is over 20 years old and the burner is rusted through, we’ll show you the condition and talk straight about whether repair or replacement is the smarter spend.

Trusted Brands We Service in Madera
We service and install gas fireplaces and components from brands we’d put in our own homes. On Madera trucks, you’ll typically find HeatShield liner materials, Gelco and Olympia Chimney components, and Famco parts. That matters because box-store substitute parts in a gas fireplace flue system are how you end up with a failed repair six months later and a company that won’t return your call. We stock common replacement parts for Madera jobs so we’re not leaving mid-repair to chase a part across the Valley. If you have an older unit or an unusual brand, we’ll locate the right part and give you a written price and timeline before we order anything.
Common Gas Fireplace Repair Problems We See in Madera Homes
- Gas inserts vented into oversized 1940s – 1960s clay-tile flues near downtown. The original flue was built for open wood fires. A sealed gas insert pushes cooler, wetter exhaust into that oversized stack, which condenses before it exits, corrodes the tile from the inside, and lets moisture bleed into your chimney structure. This is the single most common hidden problem we document on camera in Madera’s older neighborhoods.
- Stage-two creosote in flues where the homeowner “barely burns.” Madera’s No-Burn Days compress the burn season into a handful of permitted cold-snap days. When you light a fire on those days with wood that hasn’t fully seasoned and burn it low to avoid visible smoke, you get tar-like creosote regardless of how few fires you lit. We see this in gas fireplaces too when the owner occasionally burns wood in the same firebox.
- Rusted-wide-open dampers and corroded smoke chambers in original brick fireboxes. Decades of Central Valley heat cycling followed by fog-season moisture does real damage to mortar and damper assemblies in Madera’s older masonry fireplaces. A rusted damper means the stack never closes, and that’s warm house air escaping up the flue every winter night.
- Zero-clearance fireplaces in 1990s – 2000s tract homes with degraded liners hidden behind the insert. Owners in these subdivisions often run a gas log set for years without ever getting a Level 2 inspection. The liner behind the insert degrades slowly, masked by low annual burn counts, until a smoky odor or pilot failure forces someone to look. By then, the fix is often a reline, not a part swap.

FAQs – Gas Fireplace Repair in Madera
Because the flue condition in a Madera home almost never matches the burn count the homeowner reports. The San Joaquin Valley Air Pollution Control District’s No-Burn Days and winter temperature inversions mean most Madera residents burn only a handful of times per year, and when they do, it’s often cold, damp wood smoldered at low temperatures. That produces stage-two creosote even with a gas fireplace that occasionally burns wood in the same firebox. More importantly, gas combustion still produces exhaust that has to go somewhere, and a cracked or blocked flue is a carbon monoxide risk regardless of how often a fire is lit. We bring the camera on every gas fireplace call in Madera so you can see what’s actually in there, not what the burn count suggests. Call (336) 863-3889 to schedule an inspection.
Yes, and these are actually the units we service most in Madera’s newer subdivisions. Zero-clearance fireplaces take specific replacement parts, and we carry common components for these units on our Madera trucks, including parts from Olympia Chimney and Famco. The bigger issue with 1990s and 2000s tract homes is what’s behind the insert. We routinely find liner degradation and hidden creosote accumulation on units that have never had a Level 2 inspection. We’ll pull the logs, run the camera, show you the footage, and quote only what the condition actually calls for. Call (336) 863-3889 to book a service call.
Generally no. SJVAPCD No-Burn Days restrict wood burning, not gas appliances. Gas fireplaces remain legal to operate during No-Burn Days, and repairing them is never restricted. The No-Burn Days do affect repair scheduling in one practical way: the compressed burn season means we get a rush of calls in late November and December from homeowners who tried to light a fire on the first permitted cold day and found their unit dead. Booking a pre-season inspection in October gets you ahead of that rush and gives you a fireplace that works when Madera finally gets a cold snap. Call (336) 863-3889 to schedule ahead.
In Madera’s older homes, the usual cause is negative air pressure pulling residual creosote or soot odors back down the flue, especially when the damper is rusted open or the flue was oversized for the gas insert vented into it. On a call off North D Street near downtown, one of our techs found exactly this in a 1950s stucco home: a gas insert vented into an original masonry flue with a corroded damper and stage-two creosote crusting the smoke chamber above it. A camera inspection showed the homeowner the tar-glazed chamber on screen, we relined the stack with HeatShield-sized liner, and the odor never returned. If your Madera living room smells smoky when the fireplace is off, don’t ignore it. You may have a blocked or deteriorating flue, not just a lingering smell. Call (336) 863-3889 and we’ll trace it.
We avoid it by showing you the camera footage before we quote anything. Nothing gets recommended in a Madera home without visual documentation you can see with your own eyes, in real time, on our screen. If your flue is sound, we’ll tell you it’s sound and we’ll tell you when to have it checked again. If the liner is cracked, we’ll show you the crack. If the smoke chamber is glazed with creosote, you’ll see the glaze. That’s the Alcott standard under Ruben Castellano, and it’s why our written quotes in Madera specify exactly what the camera showed and what we’re doing about it. When you call (336) 863-3889, the estimate is free and the diagnosis is on camera or it isn’t a recommendation.
