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 Fresno’s Preferred Gas Fireplace Repair Company
Fresno homeowners call us because we show our work before we ask for a decision. Every Gas Fireplace Repair in Fresno visit includes camera footage of the flue interior, the firebox, and the burner assembly, displayed on a tablet while our technician stands next to you. If the flue tiles are spalled or the damper is wired open, you see it. If the gas valve is fine and the problem is actually a starling nest, you see that too.
Ruben Castellano built Alcott Chimney Sweep on a simple rule: no recommendation without camera evidence the homeowner can see and understand. That matters in Fresno, where the industry’s worst upselling targets people with 60-year-old clay tile flues and vented gas log sets shoved into chimneys never designed for them. Our written price arrives before any work begins. Our written guarantee covers every repair. If the repair fails, the second visit is free. That’s the 365-Day Done Right Promise, and it’s been standard since 2002.
Every technician is background-checked, identity-verified, uniformed, and announced to you by name and photo before arrival. At the door, they show a photo ID badge. No exceptions. That’s the Threshold Standard, and it solves the problem of opening your door to a stranger you can’t verify.
Our Gas Fireplace Repair Services in Fresno
Gas Fireplace and Gas Log Set Inspection with Flue Camera Evidence
We start every Fresno gas fireplace repair with a camera inspection of the entire venting path, not just the burner. Most gas fireplace problems in this city are venting problems in disguise. A sooting flame, lazy ignition, or gas smell often traces back to a flue obstruction or a damper that won’t open far enough to establish draft. We show you the footage before recommending anything.

Venting Verification for Gas Appliances in Original Masonry Chimneys
In Fresno’s Tower District, central Fresno, and the southwest side, thousands of 1950s and 1960s tract homes now run vented gas log sets through original clay tile flues that were built for wood fires. Gas appliances need a properly sized, intact liner and a functioning damper, and they often have neither. We verify venting against the appliance manufacturer’s requirements, and when the flue isn’t right, we tell you plainly whether it needs repair, resizing, or can safely operate as-is.

Damper, Firebox, and Chimney Crown Repair Tied to Gas Appliance Draft
Fresno summers above 105°F crack masonry crowns and mortar joints. Tule fog dampness then wicks into those cracks and rusts out dampers, grates, and burner assemblies before the first fall ignition. We repair crowns with professional-grade materials, restore damper linkage that’s been wired open, and rebuild fireboxes so the draft actually works.

Repair of Damaged Clay Tile Liners Using HeatShield or DuraFlex
When camera inspection shows spalled clay tiles shedding mortar into the smoke chamber, we repair the damaged section rather than defaulting to a full reline. HeatShield cast-in-place resurfacing rebuilds the flue interior without tearing out the original masonry, and DuraFlex liner systems give gas appliances a properly sized, listed venting path. We’ll show you the before and after footage.

Trusted Brands We Service in Fresno
We install and service gas fireplaces, log sets, liners, and components from Olympia Chimney, Famco, Copperfield, and DuraFlex, the same brands chimney professionals specify. When a Fresno repair needs a replacement thermocouple, burner assembly, or damper part, we source the correct component rather than improvising a big-box substitute. That speeds up turnaround and means the repair holds through a full winter of legal burn days.
Common Gas Fireplace Repair Problems We See in Fresno Homes
- Gas log sets vented into original clay tile flues never listed for gas. No Burn days pushed thousands of Fresno homeowners toward vented gas logs as the reliable alternative, but many of those appliances were tapped into 1950s chimneys built for wood only. The result is spillage, sooting, and draft failure that reads as a gas valve problem but is actually a venting one.
- Owl and starling nesting during extended No Burn idle months. When a Ventura or Central Fresno chimney sits unused for three or four months, birds move in. The nest blocks the draft, and the homeowner often discovers it only when the gas logs won’t stay lit. This one is predictable in Fresno; we check for it on every call.
- Summer heat cracking the crown, then Tule fog rusting internal components. A 105°F July afternoon thermally stresses the masonry crown. Fog season condensation then seeps into those cracks and corrodes the damper and burner assembly before burning season even starts. By the time you light the first fire, the damage is done.
- Spalled clay liners shedding mortar onto the smoke chamber shelf. The symptom looks like a gas pressure problem: weak flame, delayed ignition, intermittent shutdown. The camera shows the real story, chunks of mortar bridging the flue and choking the draft.

FAQs – Gas Fireplace Repair in Fresno
The most likely cause is a blocked or obstructed flue, not a gas valve failure. Birds nesting during idle months block the draft, or spalled clay tile mortar has fallen onto the smoke chamber shelf and choked the venting path. We diagnose it with a camera, show you the footage, and fix what’s actually wrong. Call (336) 863-3889 for a free estimate.
Yes. A 1950s Tower District home almost always has a masonry chimney with original clay tile liners, and any gas appliance vented into it needs venting verification before burner work makes sense. A 1990s or 2000s North Fresno home more likely has a factory-built zero-clearance fireplace with a listed metal flue, where the repair is usually a straight component replacement. The camera tells us which situation you have, and we explain the difference on-site.
In most cases, yes, but the chimney usually needs a properly sized, listed liner installed first. A gas appliance vented through an oversized or deteriorated clay flue won’t establish proper draft, which causes sooting and spillage. We show you the flue condition on camera, then give you a written price for the liner work before any gas log repair proceeds. Call (336) 863-3889 and we’ll walk you through it.
First-degree creosote is a light, dusty soot that brushes off easily. Third-degree creosote is a hardened, tar-like glaze that forms when chimneys cycle through extreme heat and cold, and it’s common in Fresno flues that sit cold and damp through Tule fog season, then run hot during short legal burn windows. Third-degree creosote can’t be removed by brushing alone and is the form most associated with chimney fires. Even gas log sets can accrete it when the flue is improperly sized.
Once a year, ideally in early fall before burn season starts. Fresno’s extended No Burn idle periods invite nesting, moisture, and component corrosion that go unnoticed until you try to light the fire and it won’t stay lit. An annual camera inspection catches those problems while they’re cheap to fix. The inspection is part of our standard service call, and the estimate is free.
