Call (254) 276-4116 and a live person picks up, 24/7, no voicemail loop.
How Olympia Chimney Products Fail – and How We Fix Them
Olympia Chimney builds solid gas fireplace components, but every brand has its patterns. After years of service calls across San Antonio, from Alamo Heights to Stone Oak to older homes near Woodlawn Lake, we see the same handful of failures repeat. Here’s what actually goes wrong.
- Thermopile drift in Olympia’s millivolt gas valve systems. The thermopile is the small sensor that generates the tiny electrical charge telling your gas valve, “yes, the pilot is lit, it’s safe to open.” Over time, especially in San Antonio’s humidity swings, thermopiles weaken. Your fireplace lights, runs for ten minutes, then shuts off like someone blew it out. A tech who doesn’t know Olympia systems will replace the gas valve for $400 when the real fix is a $60 – $90 thermopile. We test the millivolt output before quoting anything.
- Pilot assembly corrosion on Olympia’s Vent-Free and B-Vent gas fireplace lines. The pilot tube and orifice are small brass components. San Antonio’s hard water doesn’t matter here, but the airborne minerals from limestone and the occasional salty Gulf air do. Corrosion narrows the pilot flame to a weak yellow sputter. You’ll hear the igniter clicking longer than it used to. We clean or replace the pilot assembly rather than condemning the whole log set.
- Burner port blockage creating uneven flames. Olympia burners, especially on their older direct-vent units, develop clogged ports on one side. You’ll see a lazy, orange flame on the left and a strong blue flame on the right, or a flame that licks up and touches the logs, which produces soot. The cause is usually dust, pet hair, or spider silk inside the burner tube. We pull the burner, clear the ports with the right gauge, and verify flame pattern with photos before we call it done.
- Glass gasket leaks on Olympia direct-vent fireplaces. The ceramic glass front seals against the firebox with a fiberglass gasket. When that gasket compresses or deteriorates, the fireplace draws room air in through the seam instead of pulling combustion air from outside. The classic symptom: the flames look weak and the glass fogs up faster than it used to. A bad gasket also lets carbon monoxide seep into the living space. We replace the gasket, check the glass for microcracks, and run a combustion-air test.
- Log set deterioration on Olympia’s fiber-ceramic refractory logs. Over years of heat cycling, the log material cracks and crumbles, especially around the burner ports. You’ll notice small sand-like particles in the bottom of the firebox or a flame that jumps around erratically. Crumbled material can partially block the burner and create hot spots on the firebox floor. We’ll match the replacement log set to your Olympia model, using OEM when it’s available within a week, or a quality aftermarket refractory set when OEM is backordered and you don’t want to wait two months.

Our Olympia Chimney Gas Fireplace Repair Process
Here’s exactly what happens when you book an Olympia Chimney gas fireplace repair with us in San Antonio.
- 1
Call and book. You reach a live person at (254) 276-4116, day or night. We ask which Olympia model you have, what the fireplace is doing, and when you’re available. You get a tracked arrival window, not a four-hour guess.
- 2
Arrival and visual inspection. Our tech arrives in uniform, introduces himself, and lays eyes on the fireplace. He checks the pilot flame, burner condition, glass and gasket, and the gas line connections. He’ll take photos before anything is touched.
- 3
Diagnostic testing. For gas fireplaces, this means testing thermopile or thermocouple millivolts, checking gas pressure at the valve, inspecting burner ports, and verifying venting on direct-vent units. If your fireplace is direct-vent, he’ll check the vent run for blockages or disconnected sections.
- 4
Written price, no work until you approve. You see the parts recommendation, whether OEM or quality aftermarket, and the full price in writing. You approve before anyone turns a wrench. If the fix isn’t worth the cost of the fireplace, we’ll tell you that too and show you why with photos.
- 5
Repair and clean-up. We replace the failed part, clean the burner and pilot assembly, reassemble the unit, and restore the firebox to working condition. We don’t leave parts on your hearth.
- 6
Test and document. We run the fireplace through a full ignition cycle, check the flame pattern, and photograph the result. You get before-and-after photos and a digital invoice you can pay from your phone. Every repair carries a written 365-day guarantee with a free second visit if the repair fails.

Why San Antonio Homeowners Call Hadley Chimney San Antonio for Olympia Chimney Work

Every repair carries a written 365-day guarantee, and if it fails, we come back free. You’ll get before-and-after photos on every job, so you can see your own firebox and verify the work was actually done, the same visibility you’d expect from a rideshare drop-off. We also stock and work with DuraFlex liner systems, HeatShield ceramic repair compound, and Gelco products, so if your Olympia repair uncovers a venting or firebox issue that needs a different brand’s component, we’re not starting from scratch.

FAQs
No, not automatically. As an independent Olympia Chimney service provider, we repair units following the same service practices any qualified gas fireplace technician would use. If your fireplace is still under Olympia’s factory warranty, we’ll tell you whether the failed part is covered before you pay out of pocket. Then we’ll either facilitate the warranty part or talk through whether an OEM replacement or quality aftermarket part makes more sense for your situation. Call (254) 276-4116 and we’ll walk through it.
Most common Olympia Chimney parts like thermopiles, pilot assemblies, and gaskets are available from our local and regional suppliers within a few days, and we carry the most frequent replacements on our trucks. When an Olympia OEM part is backordered for weeks, we’ll show you a quality aftermarket option with the same spec and let you choose. The written price comes before we order anything, so you’re not committed until you know the cost.
Repair wins when the firebox, valve, and venting are structurally sound. If the repair cost is over 50% of a new gas insert, or if the firebox has cracks that affect combustion safety, we’ll say so plainly and show you the photos. We never recommend replacement just because it’s a bigger ticket. We’d rather repair a good Olympia unit and earn your next call.
Most repairs are done the same visit. We carry the most common Olympia failure parts on the truck. If the part is unusual or we need to order OEM, we’ll give you a straight timeline and the written price before you commit. You’ll never sit through a two-week silence wondering what happened. Call (254) 276-4116 and we’ll book the visit.
Every repair carries our 365-Day Done Right Promise. If the repair fails within 365 days, we come back and make it right, free of charge. That second visit is included, not an upsell. We guarantee the repair we did, in writing, on every single Olympia Chimney gas fireplace job.
See the problem, understand the fix, then decide – that’s how it should work. Call (254) 276-4116 for a free Olympia Chimney gas fireplace repair estimate in San Antonio.
