Annual Service and Install Estimator

This one is for planning rather than for emergencies. Price the fall service on the fireplaces you have, then add anything you are thinking about: a gas log set for a masonry fireplace, a direct-vent insert, or a safety inspection and leak check for a sale or a new-to-you house. Every range comes from the pricing page.

Why fall service is the best money in this trade

The failures that show up in December are almost all visible in September. A thermopile that reads 280 millivolts still lights a cold fireplace and still quits once the box is hot. A pilot hood with a summer of dust in it lights small and yellow. A gasket that has gone hard is a sealed firebox that is no longer sealed. All three are found on a service visit, at the published price, with an appointment you chose instead of one you needed.

The Colorado Climate Center’s Fort Collins station puts the January normal at a 45.0 degree high and an 18.3 degree low, so a fireplace here runs long evenings from November through February. That is a lot of hours on parts that sat idle for six months.

What the installation numbers cover

A gas log set in an existing masonry fireplace is $600 to $1,800 plus the gas line, which is separate permitted plumbing work in Colorado. Common in Old Town and the 1970s ring, and covered on the gas logs, remotes, and blowers page.

A direct-vent insert at $4,000 to $8,000 installed includes the unit, the liner or coaxial vent, the surround, the high-altitude kit, the permit, and the inspection. Fort Collins permits fireplace installation and issues a specific Fireplace Appliance trade license for this work; unincorporated Larimer County issues a Miscellaneous Permit covering fireplaces, gas log inserts, and gas lines and gas appliances. The permits and altitude page has the jurisdiction-by-jurisdiction detail, and the installation page covers sizing and venting.

If something is broken right now rather than planned, the repair cost estimator is the tool you want instead.
