Our Gas Fireplace Repair Services in Covina
Gas fireplaces in Covina fail differently than wood-burning units in other regions. The dry heat, seismic settling, and older clay tile flues in 1950s-70s construction create a specific set of problems. Here’s what we handle most often for Gas Fireplace Repair calls across Covina:
Chimney Crown Repair
Covina’s intense summer sun causes thermal expansion that cracks chimney crowns at a rate we see far more often in foothill-adjacent neighborhoods than in the San Gabriel Valley basin just a few miles west. A cracked crown lets water into the flue, which corrodes gas fireplace components and accelerates liner deterioration. We rebuild crowns with a proper overhang and correct slope so water sheds away from the flue instead of into it.
Flue Liner Inspection and Resurfacing
Older Covina homes, especially ranch-style houses built between 1950 and 1980, often have original clay tile liners. Seismic settling misaligns liner sections, which can block gas exhaust or leak carbon monoxide into living spaces. We use camera inspections to show you the exact condition of your liner, then recommend resurfacing with HeatShield ceramic repair compound when the liner is cracked but structurally sound. Replacement with DuraFlex flexible liner systems is another option when the damage is too extensive.
Damper Replacement or Repair
In Covina’s climate, infrequent rain combined with humid winter air causes metal dampers in older fireboxes to rust through. A damper stuck open means heat loss all winter long when your gas fireplace is off. A damper rusted half-open, which we see regularly in Charter Oak homes, causes drafting problems and can trip carbon monoxide alarms. We replace or repair dampers and test the draft before we leave.
Level 2 Inspection for Gas Fireplace Conversion or Post-Earthquake Assessment
If you’re converting a wood-burning fireplace to gas in Covina, or if you’ve felt any seismic activity and want to check your flue’s integrity, a Level 2 inspection is the right call. We document everything with photos and give you a written report showing exactly what we found. This is especially important in Covina Hills, where clay tile flues in older homes are more prone to misalignment from settling and seismic shifts.

Common Gas Fireplace Repair Problems We See in Covina Homes
- Cracked chimney crowns from thermal expansion. Covina’s summer sun beats down on exposed masonry crowns, and after decades of heat-cool cycles, hairline cracks form. Water seeps in, corroding gas fireplace components and flue liners below. Pre-winter crown inspection should be on every Covina homeowner’s list.
- Spalled clay tile flue liners. The dry heat-cool cycles in Covina, combined with seismic settling in 1950s-70s homes, cause clay tile liner sections to flake, crack, and misalign. This blocks gas exhaust and can leak carbon monoxide into living spaces. A camera inspection shows the damage plainly.
- Rusted dampers stuck open or half-open. Covina’s mild, wet winters and infrequent rain create conditions where metal dampers in older fireboxes rust through. A damper stuck half-open causes drafting issues and heat loss when the gas fireplace is off. We see this constantly in Charter Oak and other older Covina neighborhoods.
- Drafting issues that trip carbon monoxide alarms. When flue liners crack or dampers corrode, gas fireplace exhaust doesn’t vent properly. We’ve responded to calls in Covina where a gas log set was drafting poorly enough to trip a CO alarm. This is not a “keep an eye on it” situation. Call us.

FAQs – Gas Fireplace Repair in Covina
Once a year, even with light use. Covina’s dry climate means creosote buildup is less of a concern than in wetter regions, but cracked crowns, spalled clay liners, and rusted dampers happen regardless of how often you run the fireplace. A quick annual inspection catches these before they become carbon monoxide risks or expensive liner replacements. Call (661) 402-9036 to schedule one.
Yes. A cracked crown lets water into the flue, which corrodes gas fireplace components and causes liner deterioration. In Covina Hills, where thermal expansion from intense summer sun cracks crowns at a higher rate than basin communities, this is one of the most common causes of poor draft and CO alarm trips. We rebuild crowns with proper overhang and slope so water sheds away from the flue. Call (661) 402-9036 for a crown inspection.
Because your flue liner is likely cracked or misaligned, or your damper is rusted and not fully open. Charter Oak’s older ranch homes with original clay tile liners are prone to both. Smoke smell means exhaust isn’t venting properly, which is a carbon monoxide risk. We’ll camera-inspect the flue, show you the photos, and give you a written repair quote. Call (661) 402-9036 to book.
Not typically. Third-degree creosote, the hard, glazed tar buildup, comes from burning wood, especially wet or unseasoned wood. Gas fireplaces don’t produce creosote in the same way, but if your Covina home had a wood-burning fireplace that was later converted to gas, old creosote deposits can remain in the flue and harden over time. A Level 2 inspection tells you what’s actually in there. Call (661) 402-9036 for an appointment.
Often, yes. Covina’s foothill-adjacent neighborhoods get wind patterns that can cause downdrafts, which push exhaust back into the living space. A properly sized cap with the right mesh and height reduces downdrafting and keeps debris and animals out. We’ll match the cap to your flue size and your home’s specific wind exposure. Call (661) 402-9036 and we’ll assess what you need.
What Covina Homeowners Should Know About Gas Fireplace Safety
Gas fireplaces involve gas lines and exhaust systems. If you smell gas or your carbon monoxide alarm goes off, leave the house and call your gas utility immediately, then call us once the immediate hazard is cleared. We don’t give step-by-step DIY instructions for gas line or flue work because doing it wrong can kill you. That sounds blunt, but it’s the truth. A trained professional with the right tools and a camera inspection is the only safe way to diagnose and fix these problems.
We drove up to a ranch-style home off East Puente Street in Charter Oak where a gas log set had been drafting poorly and tripping a carbon monoxide alarm. Our tech found a clay tile flue liner spalled from decades of dry heat-cool cycles, a chimney crown with a hairline crack, and a damper rusted half-open. After a Level 2 inspection, we installed a HeatShield resurfacing system, rebuilt the crown with a proper overhang, and corrected the draft before relighting the fireplace. The homeowner got photos of every step. That’s how we work.
