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.

Ruben Castellano founded Alcott Chimney Sweep in 2002 because he saw too many Fresno-area homeowners being sold chimney repairs they couldn’t verify. That’s still the problem we solve here: no recommendation without camera evidence you can see for yourself, and no repair without a written price in your hand before work starts.
Why Alcott Chimney Sweep Is Sunnyside’s Preferred Gas Fireplace Repair Company
Most of the gas fireplaces we service in Sunnyside are vented gas log sets installed into original site-built brick fireplaces from the 1960s, 1970s, and early 1980s. These stacks were designed for wood fires, not gas appliance exhaust, and the combination of 105°F summer heat and damp tule-fog winters works on mortar joints and clay-tile flues in ways that show up as gas-smell complaints, backdrafting, and flame behavior problems. We know these failure patterns because we see them every week on streets like Kings Canyon Road, Clovis Avenue, and the residential blocks south of Huntington Boulevard.
Every technician who comes to your door in Sunnyside is background-checked and identity-verified under the Threshold Standard. You’ll receive their name and photo before they arrive, and they carry a photo ID badge they’ll show at the door. No exceptions, no anonymous contractors in an unmarked truck. That matters to the parents with young kids, the homeowners who are alone during the day, and the older residents who want to know exactly who’s about to step onto their porch.
We also answer our phones around the clock with a live person. When a burn-day announcement from the San Joaquin Valley Air Pollution Control District triggers a burst of calls from Sunnyside homeowners who suddenly want a sweep and safety check, you won’t get sent to voicemail. You’ll get a schedule time.
Our Gas Fireplace Repair Services in Sunnyside
Gas Fireplace Repair
When a gas fireplace in Sunnyside won’t stay lit, produces yellow or flickering flames, or leaves a gas smell around the firebox, the cause is usually not the gas valve. It’s more often a failed thermopile connections, a clogged burner port, or a damper issue tied to the original masonry stack. We diagnose the actual problem with combustion testing and camera inspection, then show you what we found before recommending any repair. Our Gas Fireplace Repair team carries common components for the brands found in these older ranch tract homes, so many jobs are completed same-visit.
Level 2 Inspection With Camera Evidence
A Level 2 inspection is what separates honest work from the upselling that runs through this trade. We run a camera through the flue and capture video of the actual condition: deteriorating clay-tile liners, disconnected vent connectors, spalled mortar, animal debris. You see every frame. If we recommend work, it’s because the footage shows a genuine need. If the flue is fine, we’ll tell you that too and you’ll see it on the screen. That’s how it should work, and it’s how we do it for every Sunnyside customer concerned about a 50-year-old chimney.
Vent Connector and Damper Replacement
Vented gas logs route exhaust through a damper and connector system originally built for burning wood. Decades of valley heat and damp fog seasons corrode these components. The result is a damper that won’t fully close, a vent connector that’s rusted through or disconnected, and exhaust that backs into the living space instead of drafting up the flue. We replace these with professional-grade components from Olympia Chimney, sized correctly for gas appliance venting, and we verify draft with testing before we leave. In Sunnyside, where the inversions already reduce natural draft on cold mornings, this repair makes a noticeable difference.
Gas Log Set Installation and Conversion
Some Sunnyside homeowners want to keep the look of the original brick fireplace but eliminate the wood-smoke pollutants that trigger SJVAPCD curtailments. Converting to a vented or vent-free gas log set is a common solution, but it must be done with the right venting configuration for the home’s flue geometry. We install gas log sets with the correct venting for each stack, verify combustion and carbon monoxide levels, and explain the plain differences between vented and vent-free options without pushing an upgrade you don’t need.

Trusted Brands We Service in Sunnyside
We carry and install professional trade brands, not box-store substitutes. That means Copperfield venting components, DuraFlex liner systems, Famco dampers, and HeatShield resurfacing materials are on our trucks when they’re needed for Sunnyside jobs. Because so many of these homes share the same era of construction and the same fireplace types, we know which parts fit the common configurations without the multi-week wait that comes from ordering generic replacements. When your gas fireplace is down during a cold tule-fog spell, that parts availability is the difference between a warm living room and a cold one.
Common Gas Fireplace Repair Problems We See in Sunnyside Homes
- Vented gas logs in unlined or clay-tile flues: Many 1960s-80s ranch homes in Sunnyside had wood-burning fireplaces that were later converted to gas without proper flue adaptation. Gas exhaust is cooler than wood smoke, so it condenses inside these old clay-tile flues and accelerates deterioration. The fix is often a properly sized liner system, not a new gas valve.
- Damper failures from extreme temperature swings: Summers above 105°F expand the cast-iron damper assembly; damp fog winters contract it. After a few decades of that cycle, dampers seize, warp, or won’t seat. You’ll notice a persistent cold draft or a gas smell even when the fire is off.
- Firebox cracking from structural movement: Original brick fireboxes in Sunnyside’s older ranch tracts develop spalling mortar and hairline cracks from the valley’s thermal stress. Other companies misdiagnose this as a gas control problem. We put a camera on it and show you the actual crack, then explain whether it’s cosmetic or needs structural repair.
- Backdrafting on cold mornings during inversions: Tule-fog inversions trap cold, dense air at chimney-top level, reducing natural draft. Combined with a partially closed damper or a corroded vent connector, that forces exhaust back into the room. This is why we always test draft and carbon monoxide levels during a repair visit, not just check the flame.

FAQs – Gas Fireplace Repair in Sunnyside
Backdrafting on cold mornings is usually caused by the tule-fog inversions that sit over the San Joaquin Valley floor during winter. These inversions trap cold, dense air at chimney-top level, which reduces the natural draft your gas fireplace needs to vent properly. If your damper is corroded or your vent connector is loose or disconnected, that reduced draft pushes exhaust back down the flue and into the living space. We test draft and carbon monoxide during every repair visit to identify whether the cause is weather-related inversion, component failure, or both. Call (336) 863-3889 and we’ll diagnose it properly.
Most 1970s-era homes in Sunnyside’s ranch tracts have original clay-tile flues that were never designed for gas appliance exhaust. Gas burns cooler than wood, so its exhaust condenses inside the flue and creates acidic residue that eats away at clay tile and mortar. If your gas fireplace vents through that original flue, a camera inspection will show whether the tile is intact or deteriorating. We only recommend a liner when the footage shows it’s necessary. That’s the difference between a DuraFlex liner installed because you need it and one sold because someone had a quota.
When the SJVAPCD lifts a no-burn curtailment, the phone rings constantly in Sunnyside. Homeowners who haven’t touched their fireplaces in weeks suddenly want a sweep, a safety check, and sometimes a repair, all before the next curtailment drops. Gas fireplaces aren’t subject to burn-day restrictions the way wood fires are, but the demand spike still affects scheduling for every chimney service. We answer live and we schedule honestly. Call (336) 863-3889 and we’ll give you a real appointment window, not a vague promise.
Yes. Most gas fireplace repairs in Sunnyside homes don’t require removing or rebuilding the original brick firebox. Component replacements like dampers, vent connectors, thermopiles, and burner assemblies are all serviceable from inside the existing firebox. The only time full masonry work enters the picture is when camera inspection shows structural cracking that affects safety or function. We’ll never recommend demolition to sell you a bigger job. If the brick is sound, we work inside it.
We carry and service professional-grade venting and component brands including Copperfield, Famco, DuraFlex, and Olympia Chimney. These are the brands chimney professionals specify for gas appliance venting, and because Sunnyside’s housing stock is dominated by the same era of ranch construction, we stock the common replacement parts locally rather than ordering each time. That means faster turnaround when your fireplace goes down during a cold fog spell. Call (336) 863-3889 and we’ll confirm availability for your specific setup.
