The moment you realize your fireplace isn’t working can be frustrating and even scary. You may be relying on your fireplace as a primary or backup heat source, or you may be worried about the possibility of a gas leak. Either way, you want your gas fireplace repair done quickly.

At Four Day Fireplace, we want to help you get your fireplace working well as soon as possible. Below, we discuss common fireplace issues, when to call a professional, and how much gas fireplace repair services cost today.

Why Isn’t My Gas Fireplace Working?

If your fireplace isn’t working, the first thing to do is check your thermostat settings. Your fireplace won’t turn on when the thermostat is set lower than the room temperature. For gas fireplaces that you turn on with a remote, you may want to test and replace the remote batteries as well.

If neither the thermostat nor the remote batteries are the source of your fireplace issue, you should call a professional. There are many different parts that could be malfunctioning, and you should not touch them unless you’re a trained professional. DIY fireplace fixes will usually void your manufacturer’s warranty.

Signs Your Gas Fireplace Needs a Repair

Gas fireplaces tend to be reliable, but they may still need repairs once in a while. If you notice any problems with your fireplace, including one of the following, it’s time to call a professional.

  • Unusual noises are often a sign that a part is broken or out of place. A fireplace technician can find the source of the noise and fix the issue in a way that maintains any warranties you have.
  • Odors from gas fireplaces may signal a leak, which is a serious hazard. If you smell anything unusual from your gas fireplace, evacuate the area and call a professional to come ASAP.
  • Inefficient heating is sometimes caused by faulty or failing fireplace parts. A fireplace technician can check if you need any work done on your fireplace to improve its efficiency and reduce your energy bills.
  • Pilot light issues, such as a pilot light that won’t turn on or stay lit, can have several different causes. A fireplace technician can diagnose and fix the issue.

The Cost of Gas Fireplace Repairs

Gas fireplace repair costs can vary quite a bit depending on what needs to be fixed, what area you live in, and which contractor you choose. Below, we’ve listed some typical pre-tax starting prices and descriptions for common gas fireplace repairs in Washington State. 

Keep in mind that these are just starting prices based on early 2024 pricing models. You can expect to pay more if the repair is more complex than usual or if fireplace manufacturers’ part prices increase.

Thermocouple or thermopile replacement: Starting at $235 

Thermocouples and thermopiles are safety devices that control the gas valve and prevent gas leaks. If one of these parts is faulty, it can keep your gas fireplace from staying lit. You can expect to pay at least the price listed above for time and materials on a replacement.

Thermostat installation: Starting at $150

You can expect to pay at least this price to install a wall thermostat that can turn your gas fireplace on and off. The final quote depends on which thermostat you choose and whether other work needs to be done before installation.

Pilot Assembly Replacement: Starting at $515

The pilot assembly on a gas fireplace is a safety feature that detects when the pilot light is lit before the thermocouple sends the signal to open the gas valve. If the pilot assembly needs to be replaced, you can expect to pay at least the price above for time and materials.

Gas Valve Replacement: Starting at $590

Fireplace gas valves don’t last forever. If the valve doesn’t stay open when needed, it can be hard to ignite the fireplace or keep it lit. On the other hand, a leaky valve — usually signaled by hissing sounds or unusual gas odors — is a major safety concern. 

If you think you have a gas leak, you should evacuate the area until it’s fixed and call a trusted fireplace professional immediately. Regardless of why your gas valve needs to be replaced, you can expect to pay at least the starting price above.

Honeywell Gas Fireplace Retrofit: Starting at $1175

Older Honeywell gas fireplaces used a type of valve that has been discontinued. If you need one of these valves replaced, you must get the fireplace retrofitted with SIT conversion. Unfortunately, this is an expensive repair. The total cost for all time and materials on this type of repair starts at $1175.

Fan Replacements and Upgrades: Starting at $510

Fans for gas fireplaces can be pricey. Assuming you already have an electrical connection for the new fan, you can expect to pay the amount above or more for time and materials. Adding a new fan without an existing electrical connection will cost more and may require additional contractors.

Gas Fireplace Fan Repairs — Snap Disc or Rheostat: Starting at $225

A snap disc is a device that turns the gas fireplace’s fan on and off based on the fireplace temperature. A rheostat has the same function and can also control the speed of the fan. Repairs for either part usually start at the price above.

Gas Fireplace High Limit / Over-Temp Switch Replacement: Starting at $215

The fireplace high limit or over-temp switch is a safety device that cuts the gas supply if the burner gets too hot. If you need a replacement for this part, you can expect to pay at least the amount listed above for time and materials.

Window Gasket Replacement: Starting at $85

The window gasket seals the window on your gas fireplace. It should fit around the edge of the glass to create a seal on both sides of the window. Replacing a window gasket with ¾” self-adhesive flat gasket material is often a relatively inexpensive repair, sometimes under $100.

Ceramic Glass Replacement: Starting at $1175

Ceramic glass is one of the most expensive parts to replace on a fireplace. If you need 2’ x 3’ ceramic glass and gasket to replace broken or damaged glass on your fireplace, you can expect to spend at least the amount listed above, if not more.

Choosing a Gas Fireplace Repair Company

It’s important to choose a trustworthy company for your gas fireplace repair. It takes only one unreliable contractor to cause long delays, unforeseen expenses, or potential safety hazards.

A trustworthy fireplace shop will be able to give you an estimate before they complete the repair. They should be transparent about their pricing and the factors that could lead to a higher bill after the work is done.
