A gas log fireplace should be inspected and serviced as needed once a year. Preventative maintenance can help keep your fireplace in working condition and save money in the long run by avoiding more costly repairs on parts that could have been fixed sooner with a regular inspection.

The cost difference between a gas fireplace and a wood-burning fireplace depends on the type of wood-burning fireplace installed. The cost to install a gas fireplace tends to be cheaper than the cost to install a brick wood-burning fireplace. Installing a gas fireplace costs about $3,600 on average, whereas the cost to build a masonry wood-burning fireplace can go up to $30,000. The cost to install a wood-burning fireplace insert or stove can cost from $700 to $6,500, about the same as a gas fireplace on average.

The cost to repair a fireplace depends on the type, extent of repairs needed, and your location. The average cost to repair a fireplace varies depending on the part of the fireplace that needs work:

• Firebox: $160–$2,500

• Refractory panel: $200–$300

• Hearth: $150–$800

• Mantel: $500–$1,200

• Pilot light: $100–$350

• Igniter: $100–$150

• Gas valve: $150–$300

• Thermocouple: $75–$350

• Thermopile: $75–$350

Yes, it can be worth installing a gas fireplace, depending on your home heating needs. The cost to install a gas fireplace can be much lower than the cost to install a comparable wood-burning fireplace. The convenience of starting a fire with the flip of a switch and turning it off just as quickly makes a gas fireplace a big time saver over starting and maintaining a wood-fueled fire. A gas fireplace also does not require ash cleanup or frequent chimney cleaning to remove creosote and other buildup that can lead to chimney fires. Gas fireplaces burn and heat much more cleanly than wood fireplaces.

A gas fireplace insert costs about $3,600 to install, on average. The cost to install a gas log insert ranges from about $700 to $6,500, depending on the size, type of insert, how it works, and heating needs. Gas fireplaces need electrical and gas lines installed properly, so hiring a pro is recommended rather than trying to DIY installation.
