Gas Fireplace Repair Pricing in Fort Collins, Colorado

Gas fireplace repair in Fort Collins costs $150 to $300 for a diagnostic service call, $175 to $350 per fireplace for annual service and cleaning, $200 to $600 installed for the common part repairs (thermocouple, thermopile, pilot assembly, remote, blower, glass), $500 to $1,000 for a gas valve, and $4,000 to $8,000 for a new direct-vent insert installed. Every number on this page is a real working range, and the rest of the page explains what puts your fireplace at the bottom or the top of each one.

Why publish this? Because “call for a free estimate” is a pricing strategy, not a service. When nobody posts numbers, the first tech in the door can quote a $900 valve for a $250 thermopile and you have nothing to check it against. So here is the market as we see it across Fort Collins, Loveland, Windsor, Timnath, Wellington, Greeley, and Estes Park.

The full price table

The service call: $150 to $300

The call covers the first hour and the instruments: combustible gas detector, CO meter, manometer, millivolt meter. On most fireplaces that hour is enough to find the fault, and on a standing-pilot unit it is often enough to fix it, because a thermocouple or thermopile swap is a 20-minute job once the bottom louver is off. The bottom of the range is a Fort Collins address with a common brand and a clear symptom. The top is a rural Larimer County address, an obscure import with no rating plate, or a unit somebody else already took apart.

If the repair goes ahead on the same visit, the diagnostic fee rolls into the job. If you decide not to repair, you still get the readings and a written diagnosis you can hand to anyone else.

Annual service: $175 to $350 per fireplace

Fall service is the best money in this trade. It includes the full cleaning and test: burner ports, pilot assembly, logs vacuumed and reset, glass cleaned with the right product, blower cage cleared, thermopile output measured, manifold pressure checked against the altitude, vent and gasket inspected, leak and CO check. Two or three fireplaces in one house get a per-unit discount because the truck is already there.

The reason it is worth $175 to $350: the Colorado Climate Center’s Fort Collins station puts the January normal at a 45.0 degree high and an 18.3 degree low, and the pilot that sat cold from April to October fails on the first night that matters. A service visit in September finds the weak thermopile at 250 millivolts before it strands you in a December cold snap at a higher, hurried price.

Ignition parts: $200 to $700

• Thermocouple or thermopile, $200 to $400. The bread and butter. Pilot will not stay lit is usually the thermocouple; pilot lights but the burner will not is usually the thermopile. The pilot and ignition page explains the millivolt test that tells them apart.
• Pilot assembly, $300 to $600. When the pilot hood, tube, and both sensors come as one part, or when a clogged pilot cannot be cleaned back to a proper blue flame.
• IPI module, $350 to $700. Electronic units that click without lighting, or that stop sparking altogether. The brand decides the part cost more than anything else on this page.

Gas valve: $500 to $1,000

The expensive part, and the one most often misdiagnosed. A valve is condemned only after the pilot flame is good, the thermopile reads in range, the switch and wiring pass, and the valve still will not open. If a bidder quotes a valve without showing you a millivolt reading, ask for it. Brand and model set the price: some valves are $150 parts, some are $450 parts, and both take the same hour to change.

Remotes, switches, blowers, glass: $150 to $600

• Remote receiver or wall switch, $150 to $400. Before paying, replace the batteries in the remote and the receiver. It solves a real share of “my fireplace is dead” calls.
• Blower, $250 to $600. Blowers do not affect combustion; they move heat. A screeching or dead blower on a 1990s direct-vent unit in south Fort Collins is a routine replacement. Adding a blower kit to a unit that never had one is the same range.
• Glass and gasket, $200 to $600. Ceramic glass is brand-specific and cannot be cut locally. A failed gasket on a direct-vent unit is a safety item, not a cosmetic one, because the sealed firebox is what keeps exhaust out of the room. The gas logs, remotes, and blowers page has more.

Installation: $600 to $12,000

• Gas log set into an existing masonry fireplace, $600 to $1,800 plus the gas line. Common in Old Town and the 1970s ring. The gas line is a separate plumbing item under Colorado’s State Plumbing Board rules, permitted and pressure-tested.
• Direct-vent insert, $4,000 to $8,000 installed. Unit, liner or coaxial vent, surround, altitude kit, permit, and the inspection. Fort Collins’ permit list says gas fireplaces need a permit; Larimer County issues a Miscellaneous Permit for fireplaces, gas log inserts, and gas lines and gas appliances. The installation page walks through sizing and venting.
• New direct-vent fireplace in a remodel, $5,000 to $12,000. Framing, the vent run, and the gas line extension push the range.

What moves the number

• Brand and ignition type. The single biggest variable. A photo of the rating plate turns a range into a number.
• Altitude and orifice. Fort Collins is at 4,997 feet; Estes Park at 7,743. The National Fuel Gas Code’s derate of about 4 percent per 1,000 feet above 2,000 feet means many replacement parts need the high-altitude orifice or kit, which adds a part but prevents the sooting and delayed ignition that would bring us back.
• Propane versus natural gas. Propane runs at higher pressure through smaller orifices. Xcel Energy natural gas covers Fort Collins and the county’s towns, and its 28-mile line up the Big Thompson Canyon serves Estes Park, but cabins off the mains there and rural addresses around Wellington run on tanks, and the parts differ.
• Access and age. A 25-year-old unit with a seized louver and brittle wiring takes longer than a 5-year-old one. Rural drive time on county roads is real.
• Permits. Passed through at cost and shown on the quote for any new appliance or gas piping.
• Season. The same thermopile costs the same in September and January. What changes in January is the wait, because the week after the first hard freeze is the busiest of the year. Book fall service and skip the line.

How to use these numbers

Send the model number, the symptom, and whether the pilot burns all the time or sparks on demand. Compare bids by what was measured, not just the total: a valve quote with no millivolt reading is a guess. Check the license; Fort Collins issues Fireplace Appliance and Gas Piping trade licenses through Building Services, and every other jurisdiction we work in has its own. And if the honest answer is “your remote needs batteries,” you will hear it for free. Process questions are on the FAQ; who does the work is on the about page.
