Our Gas Fireplace Repair Services in Pomona
Custom Stainless Steel Chimney Cap Installation
In Pomona’s historic neighborhoods, an uncapped chimney flue is an open invitation for rain, leaves, and nesting birds. We fabricate and install custom stainless steel caps sized to your exact flue dimensions. For Lincoln Park Craftsman bungalows with original clay tile liners, a properly fitted cap is often the single most effective repair we make. It stops water from pooling at the base of the flue, which is what causes rusted dampers, corroded gas valves, and that musty smell that drifts into the living room when the fireplace is off. We install caps from Copperfield and Gelco, brands built for Southern California sun and rain.
Damper Repair and Replacement
A gas fireplace damper that will not close properly leaks conditioned air out of your Pomona home year round. In the summer, your AC dollars escape up the flue. In winter, you feel a draft. We repair and replace dampers on both masonry fireplaces with traditional throat dampers and prefabricated units with top-sealing dampers. Many Pomona ranch homes built in the 1950s and 1960s still have their original cast iron dampers, which rust through after decades of exposure to rain coming down an uncapped flue. We stock common replacement parts and can usually complete a damper repair the same visit.
Flue Liner Inspection and Repair
Gas fireplaces in Pomona older homes often vent through original clay tile liners. These liners crack. It happens during the occasional freeze-thaw cycle: moisture seeps into tiny fractures, cold nights freeze it, and the expansion widens the crack. A cracked liner allows flue gases, including carbon monoxide, to leak into wall cavities instead of venting outside. We inspect liners with a camera, show you exactly what we see on screen, and recommend repair only when the photos prove it is necessary. For lined flues, we work with DuraFlex flexible liner systems and HeatShield ceramic repair compound, materials chimney professionals actually trust.
Gas Valve, Pilot Assembly, and Thermopile Service
If your gas fireplace in Pomona will not light, holds a weak flame, or shuts off unexpectedly, the pilot assembly, thermopile, or gas valve is usually the culprit. We test millivolt output, check gas pressure, and clean or replace the pilot assembly as needed. On older systems in mid-century homes near La Verne or Diamond Bar, we often find corrosion from years of humidity exposure. We carry replacement parts for most major gas fireplace brands and will give you a written price before we replace anything.

AfterCommon Gas Fireplace Repair Problems We See in Pomona Homes
- Cracked clay tile liners from freeze-thaw cycles. Pomona rarely freezes, but when it does, original clay tile liners in older chimneys take the hit. Water absorbed into the clay expands as ice, cracking the liner. Those cracks let flue gas and carbon monoxide seep into wall cavities. We find this most often in Lincoln Park and the historic districts north of Holt Avenue.
- Water intrusion through deteriorated crowns and missing caps. Concrete chimney crowns crack over decades of sun and rain. Hairline fissures let water soak into the masonry, eventually reaching the firebox. We see rusted dampers and corroded gas valves throughout Pomona because of this, especially on homes where the original clay cap crumbled years ago.
- Bird nests and debris in uncapped flues. Starlings and sparrows love an open chimney flue in Pomona’s residential neighborhoods. A nest blocks draft. Blocked draft on a gas fireplace means carbon monoxide can spill into the living space instead of venting outside. If you hear chirping or scratching from your fireplace wall, call us before you run the fireplace again.
- Deteriorated dampers in mid-century ranch homes. Pomona’s stock of ranch homes built between 1945 and 1970 often came with cast iron dampers. Those dampers rust, warp, and stop sealing. Homeowners notice a draft, or they notice the gas fireplace pilot light flickering when the wind blows. A replacement top-sealing damper fixes both issues and saves real money on heating and cooling.
On a Craftsman bungalow in Lincoln Park, our tech found a gas fireplace with a deteriorated damper and a cracked clay tile flue liner letting rain into the firebox. We installed a custom stainless steel cap and repaired the damper, then verified proper draft with a Level 2 inspection. No more water stains or downdraft on windy days. That job is a perfect example of what Pomona’s older chimneys actually need: stop the water, fix the mechanical parts, and prove the draft is right before we leave.

FAQs – Gas Fireplace Repair in Pomona
Yes. Even a gas fireplace that burns clean needs an annual inspection in Pomona because the failure modes here are not creosote related. They are water related. Cracked crowns, rusted dampers, deteriorated clay tile liners, and bird nests happen whether you burn the fireplace once a year or every night. An annual inspection with a camera catches a cracked liner before it becomes a carbon monoxide problem. For most Pomona homes, a Level 1 inspection runs $125 – $195. Call (661) 402-9036 to schedule yours and we will send photos of everything we check.
The signs are subtle. You may notice a faint gas odor near the fireplace wall, water staining on the ceiling or wall around the chimney chase, or downdraft on windy days that pushes exhaust back into the room. In Pomona’s older Craftsman and Spanish Revival homes with original clay tile liners, cracks from freeze-thaw cycles often appear without any visible symptom at all. The only way to know for sure is a camera inspection. We lower a camera down the flue, show you the footage on the spot, and point out any cracks in the tile. You see exactly what we see. Book an inspection at (661) 402-9036 and you will have photos in hand before you decide on any repair.
Yes, in most cases. That smell is usually water-soaked creosote residue or rusting metal inside the firebox, both caused by rain coming down an uncapped flue. A custom stainless steel cap sized to your flue prevents rain from entering in the first place. Within a few days of install, the firebox dries out and the smell fades. In Pomona ranch homes where the fireplace has been uncapped for years, we sometimes also need to replace rusted components, but the cap is step one. We fabricate caps from Copperfield materials and warranty the installation under our 365-Day Done Right Promise. Call (661) 402-9036 and we will measure your flue and give you a written price.
Cracked or missing flue liners are the biggest cause in Pomona, particularly in homes built between 1900 and 1960. Original clay tile liners crack from freeze-thaw cycles and let flue gases escape into wall cavities. The second most common cause is blocked draft from bird nests or debris in uncapped flues. The third is a deteriorated damper that forces exhaust back into the room when the wind shifts. Any gas fireplace should have a functioning carbon monoxide detector in the same room. If your detector goes off, turn off the fireplace, open a window, and call us at (661) 402-9036. We will inspect the liner and draft with a camera and gas analyzer and show you the readings before we touch anything.
Because the damper does more than control draft while burning. A closed damper seals the flue so your heated or cooled air stops escaping through the chimney. In Pomona, where summer temperatures regularly pass 90 degrees, an open or warped damper leaks air-conditioned air up the chimney all day. That raises your electric bill by real money every month. A rusted or misaligned damper also lets rain and humidity into the firebox, which corrodes the gas valve and pilot assembly over time. Repairing or replacing the damper is a $195 – $420 fix that pays for itself in one Pomona summer. Call (661) 402-9036 and we will give you a written price before any work starts.
