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.
Fast, Reliable Gas Fireplace Repair Across Kerman
Gas fireplace repair in Kerman usually runs $190 – $440 for common fixes like pilot assemblies, thermocouples, and damper adjustments, with most jobs completed the same day we arrive.

Our Gas Fireplace Repair team knows Kerman’s housing stock and the San Joaquin Valley’s burn restrictions better than any out-of-town outfit. Call (336) 863-3889 for a straight answer and a free estimate before burning season turns your pilot light into a recurring headache.

- Every repair carries a written guarantee. If it fails during the coverage period, the second visit is free.
Why Alcott Chimney Sweep Is Kerman’s Preferred Gas Fireplace Repair Company
Kerman homeowners call us because the problem is rarely just the gas valve. Ruben Castellano and his crews have spent years working on the specific fireplaces that dominate this town: original clay-tile masonry chases in ranch homes off Madera Avenue, Del Norte, and the older blocks radiating from downtown. We know that when a Kerman gas fireplace pilot won’t stay lit, the cause is often tule-fog moisture settling onto a thermocouple through a spalled mortar joint, not a faulty part. That diagnosis saves you from buying a replacement assembly you don’t need.
Every technician who arrives in Kerman has passed a background check and identity verification under the Threshold Standard. You’ll know the technician’s name and see their photo before we arrive. They’ll show a photo ID badge at the door, in uniform, driving a marked vehicle. We started in 2002, and while we don’t post a street address on South Madera Avenue, our scheduling works off a Fresno, Central Valley office that dispatches locally to Kerman. A live person answers our phone around the clock, because at 11 p.m. on a January night when the house smells like gas exhaust, you don’t need a voicemail queue.
Our written guarantee covers every repair we perform in Kerman. If the repair fails within the coverage period, we come back and fix it free. That’s the 365-Day Done Right Promise, and it’s printed on your invoice, not buried in fine print. No vague commitments, no “we’ll take a look.” Written price before any work starts, written guarantee when the work is done.
Our Gas Fireplace Repair Services in Kerman
Shared-Flue and Attached-Property Diagnostics for Gas Fireplaces
The single most important service we perform in Kerman doesn’t involve turning a wrench. It’s the Level 2 inspection of back-to-back and shared masonry chases. Kerman’s 1950s – 80s tract homes were commonly built with two fireplaces sharing one clay flue tile chase between adjoining properties. If the wythe, the internal masonry divider, has cracked or failed, your neighbor’s gas log set can vent exhaust and carbon monoxide into your firebox through a missing damper seal. We inspect the entire chase with a camera, test draft with a combustion analyzer, and document what we find. You see the images. You make the call.

Damper Replacement and Top-Sealing Damper Installation
Many Kerman gas fireplaces have dampers clipped permanently open, usually because a previous owner installed gas logs and never addressed the flue. An open damper on a shared chase is an invitation for your neighbor’s exhaust to drift back into your living room. We install top-sealing dampers on clay-tile stacks across Kerman, sealing the flue at the crown when the fireplace is off while remaining compatible with gas log operation. The difference is measurable: we test draft before and after and show you the numbers.

Smoke Chamber and Flue Liner Repair on 1950s – 80s Masonry Fireplaces
Kerman’s extreme summers, regularly topping 105°F, thermally expand original clay flue tiles and widen mortar cracks all through the smoke chamber. Then winter tule fog drives moisture into those cracks, and the freeze-thaw cycle does the rest. We repair smoke chamber parging and reline flues using professional trade materials like DuraFlex and HeatShield. We don’t patch with box-store mixes. We re-mortar the wythe when shared-chase separation has failed and verify the repair with a post-installation draft test, not a verbal assurance.

Pilot, Thermocouple, and Ignition System Repairs
When your gas fireplace pilot won’t stay lit in Kerman, don’t assume it’s a cheap part swap. Moisture from tule fog settling into fireboxes through crown cracks corrodes thermocouples and burns out ignition modules faster than in dryer climates. We diagnose the root cause, replace the failed component if needed, and fix the moisture entry point so the new part doesn’t fail in the same way next winter. One repair, done right, with a written guarantee.

Trusted Brands We Service in Kerman
We service and install gas fireplaces, inserts, and log sets from the brands chimney professionals actually specify: Olympia Chimney, DuraFlex, and Copperfield. We stock common Kerman parts locally for faster turnaround on pilot assemblies, thermocouples, dampers, and gas valves.

We’ll never recommend a liner or masonry repair we can’t show you on camera first. Written price before any work starts, always.
Common Gas Fireplace Repair Problems We See in Kerman Homes
- Neighbor’s exhaust back-drafting through a shared flue tile. In Kerman’s back-to-back tract homes, a failed wythe or an open damper lets your neighbor’s gas log exhaust, including carbon monoxide, drift into your firebox. If you smell gas exhaust when your fireplace is off, call us before burning anything.
- Third-degree creosote glazed above a gas insert. On SJVAPCD curtailment nights, homeowners often overload the firebox on the next legal burn day. The prolonged high heat glazes third-degree creosote onto the smoke chamber above a gas insert. A brush can’t remove it, and it becomes a fuel load inside the flue. We remove it with proper mechanical and chemical methods, safely.
- Intermittent pilot failure from tule-fog moisture. Winter fog in Kerman doesn’t just coat the roads. It penetrates cracked crowns and spalled mortar joints, dripping onto gas burners, pilots, and thermocouples. That’s why pilots that work fine in October fail reliably in February. The fix is sealing the moisture entry point, not replacing the same part every year.
- Cracked or missing damper seals on converted gas log sets. Most Kerman gas log sets sit in fireplaces originally built for wood. The damper was either removed or clipped open during conversion. On a standalone flue, that’s a draft problem. On a shared Kerman chase, it’s a cross-contamination hazard. We reseal or replace the damper and test the draft to confirm separation from the adjacent unit.

FAQs – Gas Fireplace Repair in Kerman
Yes. If your home is one of Kerman’s back-to-back tract properties built between the 1950s and 1980s, neighboring fireplaces may share a single clay flue tile chase separated only by a masonry wythe. When that divider cracks or a damper seal fails, exhaust from the adjacent unit, including carbon monoxide, can back-draft into your firebox. A Level 2 camera inspection and draft test confirms it in under an hour. Call (336) 863-3889 to schedule one. If the wythe has failed, we’ll show you the footage before recommending any repair.
The most common cause in Kerman is tule-fog moisture. Dense winter fog settles into cracked crowns and spalled mortar joints, then drips onto the pilot, thermocouple, or burner. The thermocouple cools, the pilot fizzles, and you relight it every few nights. Replacing the thermocouple without sealing the moisture entry point means you’ll replace it again next winter. We fix the source.
It does, in two ways. First, curtailment days push Kerman households toward gas appliances, so gas fireplaces that sat unused for years become primary heat sources. Second, when a burn night finally clears, homeowners often overload fireboxes to compensate, creating intense heat that glazes creosote inside the flue, even above gas inserts. Both patterns mean more wear on gas components and more failed drafts found during inspections. Scheduling your repair before November is the smartest move, because our Kerman calendar fills when the fog settles in. Call (336) 863-3889 for a free estimate before the season compresses.
At least once a year, even if you never light it. An unused flue in Kerman collects tule-fog moisture, bird nests, and spalled mortar debris that compromise the draft the first time you do light it. Shared-chase homes need an annual check regardless of use because your neighbor’s appliance affects your flue year-round. If you can’t remember your last inspection, it’s time. Call (336) 863-3889 and we’ll schedule it.
Yes. Third-degree creosote is a hard, glazed layer that a standard wire brush can’t remove, and Kerman’s curtailment-driven high-heat burns produce it quickly. We use mechanical and chemical removal methods specified for glazed creosote, then document the smoke chamber with a camera so you can see the final result. The goal is a clean, fuel-free flue above your gas log set, not a partial job. Call (336) 863-3889 to have it assessed, and we’ll show you what we’re dealing with before we start.
On a call off South Madera Avenue, we opened the firebox of a 1962 ranch home and found the gas log set’s damper clipped permanently open while the neighbor’s flue tile in the same chase had a spalled mortar joint at the smoke chamber. Our tech’s combustion meter read CO spilling back into the living room. We installed a top-sealing damper with a stainless flue liner on the customer’s side of the stack, re-mortared the shared wythe, and re-tested draft at 0.04 in. w.c. before we called it good. That’s the kind of repair we handle regularly in Kerman’s attached and back-to-back homes. If your house sounds anything like that one, call us.
