Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

What Our Gas Fireplace Repair Service Includes

Gas fireplaces are convenient, but they’re still combustion appliances with real safety considerations. Our repair service covers the full range of what can go wrong, from the smallest component to complete system diagnostics. Here’s what we handle.

Pilot Light and Ignition Repair

A pilot light that won’t stay lit is the most common gas fireplace complaint we hear. The cause is usually a dirty pilot assembly, a failing thermocouple, or a gas pressure issue in the supply line. When you call Alcott Chimney Sweep for Gas Fireplace Repair - Huntington Park or any of our service areas, we don’t just relight the pilot and leave. We test the thermocouple output with a multimeter, clean the pilot orifice properly, and verify the flame sensor is reading correctly. If a part needs replacing, you’ll know the exact cost before we touch a single component.

Pilot Light and Ignition Repair

Thermocouple and Thermopile Replacement

The thermocouple is the safety device that tells your gas valve the pilot is lit, and the thermopile generates the small electrical current that opens the valve. Over time, both degrade from constant heat exposure, and when they fail, your fireplace either won’t start or shuts off mid-burn. We carry compatible replacements for all major brands and test the new component under load before calling the job done. This is a repair where getting it wrong can create a dangerous situation, so we’re precise about it every single time.

Thermocouple and Thermopile Replacement

Gas Valve Service and Replacement

The gas valve controls the flow of fuel to your burner, and a sticking valve can cause poor flame quality, delayed ignition, or complete failure. Sometimes a valve just needs adjustment and cleaning; other times it’s worn past saving and needs replacement. Our technicians will diagnose the exact condition of your valve and show you what a healthy part should look like versus what yours is doing. You’ll never pay for a replacement you didn’t actually need.

Gas Valve Service and Replacement

Burner and Log Set Repair

Over years of use, burners corrode, ports clog, and ceramic logs begin to crumble, which makes your flame look weak or uneven and can produce excess soot. We clean burner ports with professional tools, replace damaged log sets when necessary, and make sure the flame pattern matches manufacturer specifications. In many homes, this is the difference between a fireplace that looks fine and one that actually heats the room the way it should.

Burner and Log Set Repair

Thermostat and Remote Control Repair

Modern gas fireplaces rely on millivolt thermostats, wall switches, or wireless remotes to operate, and when these controls fail, the fireplace won’t respond even if the gas system is working perfectly. We test control wiring, replace faulty switches and remote receivers, and reprogram units that have lost their pairing. Our goal is to restore your fireplace to reliable operation with whatever simple or complex control fix it needs.

Thermostat and Remote Control Repair

Glass, Gasket, and Seal Replacement

The glass on a gas fireplace is a sealed component that keeps combustion gases where they belong, and a cracked panel or worn gasket is not something to ignore. We measure, source, and install correct replacement glass and gaskets for your specific unit. Keeping that seal intact is a real safety matter, so we take it seriously and check the seal integrity as part of every gas fireplace service call.

Brands We Service

Our technicians work on gas fireplaces from all major manufacturers, and we keep experience with specific brands sharp by servicing them continuously. We’ve repaired hundreds of units built around HeatShield components, and we carry or can quickly source the replacement parts those systems need. When a homeowner has a HeatShield-equipped fireplace that’s losing efficiency or showing signs of combustion chamber wear, we’re able to diagnose the issue accurately on the first visit.

We also regularly service units that use Olympia Chimney and DuraFlex components, which gives us a deep working knowledge of how those systems perform in real homes over years of use. Whether you have a premium unit with those parts or a builder-grade fireplace from another manufacturer, our technicians can diagnose and repair it. If we don’t have a part on the truck, we’ll give you a written price and a clear timeline before moving forward.

Signs You Need a Pro Right Now

  • You smell gas anywhere near the fireplace. This is the one sign that demands immediate action. Turn off the gas supply if you can safely reach the shutoff valve, ventilate the room, and call us at (336) 863-3889. A live person will walk you through the next steps around the clock. Never wait this one out.
  • The flame is mostly yellow or orange instead of blue. A clean-burning gas fireplace should produce a steady blue flame with minimal yellow tipping. Persistent yellow flames mean incomplete combustion, which can produce carbon monoxide. It might be a dirty burner or a venting problem, but both need a professional look.
  • Soot is building up on the glass or around the fireplace opening. Gas fireplaces should burn clean, and visible soot means something is off with the air-to-fuel ratio or the venting. Left alone, soot buildup can damage your log set and increase carbon monoxide risk inside the home.
  • The fireplace shuts off unexpectedly or won’t stay lit. This usually points to a failing thermocouple or thermopile, but it can also indicate a gas pressure problem. A fireplace that behaves unpredictably is one that needs diagnosis before the next cold evening, not after.
  • You hear a loud boom when the fireplace ignites. Delayed ignition happens when gas builds up before the pilot finally catches, and that small explosion is hard on the burner assembly and dangerous in larger volumes. It’s usually fixable with a proper cleaning and adjustment, but it will not fix itself. The sooner we see it, the smaller the repair tends to be.

Our Process, Step by Step

  1. 1
    You call and speak to a living person. No recorded menus, no “your call is important to us” hold loops. When you ring (336) 863-3889, someone answers, takes down the details of your gas fireplace problem, and schedules a window that works for you. Before the visit, you’ll get your technician’s name and photo so you know exactly who’s coming.
  2. 2
    Your technician arrives with a photo ID badge. Every Alcott Chimney Sweep technician has passed a background check and identity verification before ever stepping onto a customer’s property. This is the Threshold Standard, and we don’t make exceptions. The person at your door is the person whose name and photo you already received.
  3. 3
    We diagnose the problem and show you the work. The technician will inspect the fireplace, troubleshoot the specific issue, and explain what’s actually wrong in plain English. If there’s a part that needs replacing, you’ll see it. If the system is safe and just needs maintenance, we’ll tell you that too. We never manufacture work that doesn’t need doing.
  4. 4
    You approve a written price before any work starts. We do not perform surprise repairs. You’ll get a written price for the exact work and parts involved, and nothing starts until you say yes. This is non-negotiable, and it has been since 2002 because the alternative is guessing games disguised as service.
  5. 5
    We complete the work and stand behind it. Every gas fireplace repair comes with a written guarantee. If the repair fails, the second visit is free. That guarantee is not a limited-time offer or a warranty buried in fine print. It’s our 365-Day Done Right Promise, and it’s on every job we complete.

How Much Does Gas Fireplace Repair Cost?

A standard thermocouple or thermopile replacement typically runs $180 to $340 including parts and labor. Pilot assembly cleaning and adjustment usually falls between $130 and $220. Gas valve replacement is the bigger job, with most repairs landing in the $380 to $520 range depending on the specific valve your fireplace uses. These are real ranges based on what homeowners across the country pay for these repairs.

What moves the price up or down is mostly parts availability and how accessible the components are inside your fireplace. Some units are straightforward to open and service; others require more disassembly, which takes more time. One thing you should always be wary of is a technician who quotes a low diagnostic fee but then piles on unnecessary part replacements. You avoid overpaying by choosing a company that shows you the failed part and gives you a written price before any work begins, as we explain in our DIY vs Professional Gas Fireplace Repair: What’s Safe to Do Yourself guide. That’s exactly how we operate, and our free estimate includes the diagnosis. If the fireplace ends up being beyond reasonable repair, we’ll tell you that honestly and help you understand your options.
