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.

AfterFast, Reliable Gas Fireplace Repair Across Hayward
Gas fireplace repair in Hayward typically costs between $185 and $520 depending on whether you need a thermocouple or thermopile replacement, a gas valve rebuild, or a full flue reline. Most repairs in Hayward can be diagnosed in a single visit and completed the same day once parts are on hand. We serve every neighborhood in Hayward, from Burbank to Fairway Park to Whitman-Mocine, and our technicians arrive with pro-grade combustion test equipment, not guesswork. Call (336) 863-3889 and you’ll talk to a live person who can schedule a repair around your Hayward workday, not ours.
We’re not just a chimney company that happens to take calls from Hayward. We’re Hayward chimney people. Our Gas Fireplace Repair crews spend their days crawling through crawlspaces and up on tile roofs across the flatlands and the hills, and they know what a 1950s california tract chimney looks like inside better than most people know their own attics. That matters because Hayward’s chimneys have a problem most of the country never deals with, and it’s moving under us all the time.
Why Alcott Chimney Sweep Is Hayward’s Preferred Gas Fireplace Repair Company
Ruben Castellano, who leads Alcott Chimney Sweep, built the company on a simple rule that most trades never follow: show the customer everything. Our Hayward customers see camera footage of their own flue before they approve a dollar of repair work. Not a diagram. Not a “trust me.” We document the condition of every gas fireplace vent, every flue tile, every cracked mortar joint on video, then hand you the footage. That’s how we’ve earned our reputation in Hayward since 2002 as part of the Threshold Group family of home-service companies.
And we do something else no one in Hayward does: every technician is background-checked, identity-verified, and sent to you by name and photo before they arrive. You’ll know exactly who’s pulling into your driveway on A Street or sleeping on your couch near Carlos Bee Park isn’t happening, because you’ll already have seen their face, their name, and their Threshold Verified badge number. They show a photo ID at the door. Every time. No exceptions.
Hayward homeowners have told us for two decades that the worst part of hiring a chimney company is the stranger at the door and the surprise invoice at the end. We removed both. Written price before work starts. Written guarantee on every repair, covered for a full year, free second visit if the repair fails. Call Ruben’s team at (336) 863-3889 and you’ll get a straight answer before you commit.
Our Gas Fireplace Repair Services in Hayward
Gas fireplace repair in Hayward means more than swapping a thermocouple. The real work is often inside the flue, which is why half our jobs begin with a camera inspection. Here’s what we do most for Hayward homes.
Level 2 Camera Inspection of the Flue Liner and Smoke Chamber
Every gas fireplace repair quote in Hayward starts with a Level 2 camera inspection. We run a high-resolution camera from the firebox up through the flue liner and smoke chamber. In Hayward, this matters more than almost anywhere because the Hayward Fault is actively creeping beneath residential streets, and flue tile cracks don’t telegraph themselves. A hairline crack from fault creep can be invisible from the rooftop but wide open inside. We show you the video, explain what we’re seeing, and only then recommend work.
Gas Fireplace Insert Venting and Draft Verification
Homes across Hayward, especially post-WWII tract houses in the flatlands with original unlined or clay-tile flues, often have gas inserts vented into stacks never designed for them. That’s a carbon monoxide path, not a vent. We verify draft with actual combustion analysis equipment, not a hand over the flue, and we’ll tell you plainly if the current venting is safe to keep running or needs to be corrected before you use the fireplace again.
Relining with DuraFlex or HeatShield for Unlined or Damaged Flues
When a Hayward flue is cracked, unlined, or too damaged for safe gas venting, we reline with DuraFlex stainless or resurface with HeatShield. These are the same systems chimney professionals specify, not what you’d find on a big-box shelf. We’ve done dozens of relines in Hayward’s 1920s Craftsman bungalows near B Street and the 1950s tract homes south toward Union City, and in every case the homeowner sees the before-and-after camera footage before we call the job done.
Gas Valve, Thermocouple, and Pilot Assembly Repair
The mechanical side of gas fireplace repair in Hayward runs the usual spectrum: thermocouples, thermopiles, gas valves, pilot assemblies, burner tubes, remote control modules. The difference is that we never diagnose a failed thermocouple without also checking the venting it’s connected to, because in Hayward a “bad pilot” can be a symptom of draft failure caused by fault-creep-damaged flue tiles pulling combustion gases back into the room. We fix the part and verify the system.

Trusted Brands We Service in Hayward
We service and install gas fireplaces, inserts, and venting from Olympia Chimney, Famco, and Copperfield. Hayward homes are full of these systems, and we keep common replacement parts for all three either on the truck or within a day of the Hayward warehouse. That means a gas valve or thermocouple replacement on a 1950s brick fireplace on Gading Road isn’t a two-week wait for someone in another state to box up a part. If we don’t have it, we’ll tell you the day it arrives, not “soon.”
Common Gas Fireplace Repair Problems We See in Hayward Homes
Here are the four calls we get most from Hayward:
- Cracked clay flue tiles from fault creep. The Hayward Fault moves continuously, not just in earthquakes, and that slow movement cracks clay flue tiles inside otherwise healthy-looking chimneys. Homeowners along the Burbank, Fairway Park, and Tennyson corridors bring us fireplaces that “work fine” but are vents for exhaust into wall cavities.
- Cosmetic post-1989 patches hiding interior damage. After Loma Prieta in 1989, thousands of Hayward homeowners had their chimneys tuck-pointed. Exteriors looked fine. Interiors kept cracking. We see this constantly: pretty brick, broken flue. The only way to know is a camera scope.
- Marine-layer dampness causing mortar erosion and damper rust. Hayward sits on the bay shoreline, and the persistent morning fog keeps chimney masonry damp far longer than in inland cities like Livermore or Dublin. That means more efflorescence, more rusted dampers, more water intrusion around gas vent terminations.
- Unlined or clay-tile flues venting modern gas inserts. Gas inserts installed in the 1990s and 2000s were often vented into flues never designed for them, especially in Hayward’s post-WWII tract homes. The exhaust is too cool to draft properly, condenses inside, and silently degrades the flue while leaking carbon monoxide.

FAQs – Gas Fireplace Repair in Hayward
No. An unlined or original clay-tile flue in a 1950s Hayward tract home was built for wood smoke, not gas exhaust. Gas fireplace exhaust is cooler and condenses inside the flue, and in an unlined stack that condensation deteriorates the mortar from the inside out while the Hayward Fault’s continuous creep opens the exact kind of cracks that let exhaust enter your home. We’ll run a Level 2 camera inspection, show you the condition on video, and if a reline is needed, we’ll quote a DuraFlex or HeatShield solution in writing before anything happens. Call (336) 863-3889 for a camera-based assessment.
For most Hayward homes, no. The post-Loma Prieta patches were almost always cosmetic tuck-pointing on the exterior brick, not interior repair. The hairline cracks in the clay flue tiles, the ones opened by fault creep, were left untouched. We find this on nearly every camera inspection we do in Hayward neighborhoods like Burbank and Glen Eden: exterior looks good, interior is cracked. The only way to know is to look. We’ll show you the video, and if repairs can wait, we’ll tell you that plainly. Call (336) 863-3889 to schedule an inspection.
Hayward’s persistent marine layer traps cold, damp air near the ground, which reverses the draft in a poorly vented gas fireplace. When the flue can’t pull, exhaust backs into the room, and that’s what you’re smelling or what’s tripping your CO detector. Fault-creep cracks in the flue tiles make this worse by breaking the draft path. If your carbon monoxide alarm has gone off, stop using the fireplace, open a window, and call us at (336) 863-3889. We’ll diagnose the draft failure with combustion analysis and fix the venting, not just silence the alarm.
Yes, and Hayward’s mild climate is exactly why. Homes near the bay rarely burn enough to dry out the masonry, so the marine fog keeps the flue damp, eroding mortar and rusting dampers even when the fireplace sits idle. And a gas fireplace that’s only lit a handful of times each season still vents carbon monoxide every time it runs. We recommend a Level 2 camera inspection at least once every two years for gas fireplaces in Hayward. The inspection costs $149 to $249, and it’s credited toward any repair. Call (336) 863-3889 to book one.
Because you’ll see the footage. Every recommendation we make in Hayward is tied to a video recording of your actual flue, timestamped and shown to you before any work is approved. We don’t recommend liners from the rooftop. We don’t recommend liners because the house is old. We recommend a liner because we can put a camera inside your flue, show you the crack, and you can see the problem with your own eyes. If the flue is sound, we’ll tell you that too and recommend nothing. Our written guarantee covers every repair for a full year, and if it fails, the second visit is free. Call (336) 863-3889 for an honest, camera-first assessment.
