The price of gas logs ranges from about $200 for a basic log set to $2,500 or more for a professionally installed system with gas-line work. Most homeowners pay $700-$1,800 total, depending on whether the fireplace is vented, the burner and log quality, local labor rates, and whether a gas connection already exists.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Gas log set only | $200 | $600 | $1,500 | Price varies by size, material, and burner features. |
| Installed gas logs | $500 | $1,200 | $2,500 | Assumes a compatible fireplace; new gas lines can raise the total. |
| New gas line | $200 | $600 | $1,500+ | Cost depends on run length, access, and required upgrades. |
What Gas Logs Cost in a Standard Fireplace
A basic vented set typically costs $200-$700 for the logs and burner, while midrange sets often run $500-$1,000. Vent-free sets commonly cost $300-$900, with premium refractory ceramic logs, remote controls, or larger burners priced higher. These are equipment prices, not necessarily installed totals.
For a standard replacement in a fireplace with an existing, usable gas connection, expect roughly $500-$1,500 installed. A new line, shutoff valve, or fireplace modification can push a project to $1,000-$2,500 or more. A compatible existing gas connection is one of the biggest reasons an installation stays near the lower end.
Assumptions: Typical U.S. pricing, standard fireplace access, and ordinary residential labor; regional rates and code requirements vary.
How Burner, Log Set, and Installation Charges Add Up
Quotes can combine several different costs. The table separates common charges for a typical installation; not every project needs each item. Local taxes and unusual masonry or vent repairs may be additional.
| Quote item | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| Logs and burner | $300-$1,000 | Per set | Size, material, burner style, controls |
| Installation labor | $200-$600 | Per job | Setup, connection, testing, access |
| Gas line and valve | $200-$1,000 | Per job; longer runs cost more | Distance, wall access, pipe route |
| Removal and disposal | $50-$250 | Per job | Old equipment and debris volume |
| Permit or inspection | $0-$250 | Per permit | Municipal rules and project scope |
Labor commonly accounts for $200-$600 when the connection is ready and the fireplace needs no alterations. Ask for equipment, labor, gas piping, and permit charges as separate quote lines.
Vented or Vent-Free Logs Change the Installed Price
Vented gas logs generally require an open, working chimney and are selected for a more natural flame appearance. The log set alone often costs $300-$1,000; a straightforward installed project may total $600-$1,600. An existing chimney that needs cleaning or repair can add to the bill.
Vent-free logs do not use a chimney for exhaust, but local rules may restrict their use, and the room must meet the manufacturer’s size and ventilation requirements. Equipment often costs $300-$900, with a typical installed total of $500-$1,500 when the gas supply is ready. Confirm local approval and fireplace compatibility before choosing a vent type.
Gas-Line Distance and Fireplace Size Shift the Quote
A gas line running 5-10 feet through an accessible basement or crawlspace can be less costly than a 20-30-foot route concealed behind finished walls. New piping, wall opening and repair, or an undersized supply line can add several hundred dollars, with complex runs reaching $1,500 or more.
Fireplace width also affects equipment selection. Many sets are sold for openings around 18-30 inches, while larger openings may need a wider burner and more log material. Verify the fireplace’s front width, rear width, depth, and height against the product’s clearance requirements. Measure the firebox before comparing set prices; a low-priced unit that does not fit is not a useful quote.
What Three Gas Log Quotes Look Like
A small 18-inch vented set replacing an existing unit may cost $350-$600 for equipment plus $250-$400 for labor, for a total near $600-$1,000. This assumes a usable gas connection and no chimney work.
A 24-inch vent-free set with a remote may cost $600-$1,000 for equipment and $300-$500 for installation, totaling about $900-$1,500. A permit or additional shutoff valve may raise the quote.
A 30-inch premium set requiring a 20-foot gas-line extension could total $1,600-$2,800, including $800-$1,300 for equipment, $350-$600 for labor, and $400-$900 for piping and access work. These examples illustrate how scope changes the total more than the log-set price alone.
When Gas Log Installation Needs a Permit or New Line
Permit rules depend on the city or county and whether the work adds piping, changes a venting setup, or replaces an appliance. Permit and inspection charges may be $0-$250, but a required inspection can affect scheduling. A licensed installer can check the local requirements before work begins.
Ask whether the quote includes a shutoff valve, pressure or leak testing, removal of old logs, and any required inspection. If the fireplace has damaged masonry, a blocked flue, or a gas line that fails inspection, those repairs are usually separate. Get written confirmation of what is excluded so a low initial quote does not conceal necessary work.
How Long Installation Takes and What Labor Covers
A simple replacement may take about 2-4 hours, including removal, placement, connection, and operation checks. A new gas line or difficult access can extend the job to a full day or longer. Many installers charge a minimum service fee, often around $100-$200, even for a short visit.
Typical residential labor rates vary, but a service technician may charge roughly $75-$150 per hour. Rates in high-cost metro areas can exceed that range. Confirm whether labor is a flat installation price or an hourly charge, and whether return visits cost extra.
Which Gas Log Upgrades Are Worth Paying For?
To lower the total, compare complete installed quotes for the same vent type, firebox size, burner, and controls. A basic manual valve can cost less than a remote ignition package, while ceramic logs and realistic detailing add equipment cost without changing every homeowner’s priorities.
Keeping a functioning gas connection and avoiding unnecessary fireplace remodeling can save more than choosing the cheapest log set. If replacing an existing unit, ask whether the burner and controls can safely remain in service; do not reuse components unless the manufacturer and installer approve. Control scope first, then compare equipment tiers on an equal basis.
