Chimney Liner Cost in Lexington, KY

“A chimney liner” covers jobs that share little but the name. A short flue over a gas water heater in a ranch house is one end; a tall flue above an open wood fireplace in a two-story brick home, with a bend partway up, is the other. The band is the honest spread across this market, and nothing here moves it. Your own figure is set once someone has looked down your flue.

Flue height

The pipe runs unbroken from the appliance to the top plate, so a two-story stack takes more of it than a one-story run.

Diameter and appliance

The liner is sized to what burns below it: an open hearth, a wood insert and a gas furnace each need their own diameter, and so does a water heater.

Insulation

A wrapped liner keeps flue gases warmer, helping draft and cutting condensation. Whether this flue needs it gets a separate line on the scope.

Bends and old tile

A flue that jogs sideways, or broken tile that must come out before the pipe will pass, adds hours on the roof. The camera shows both first.

How many flues

A stack serving a fireplace and a furnace holds two flues, and each is its own reline, scoped on the same visit.

The top-out

A top plate, storm collar and stainless cap finish the job at the crown. A cracked crown found there is quoted as its own repair.

Fired clay tile was the ordinary flue lining for most of the last century, and it still goes in when a chimney is built new, set as the brick rises. In a standing stack those sections are sealed inside the masonry, and no one can lift a cracked piece out from the roof. So a cracked clay flue in an existing Lexington chimney usually gets stainless: one continuous pipe run down through the old tiles, with no joints for acidic condensation to eat into. Why gas exhaust is so hard on old clay has its own page. Clay returns only when the stack is coming down to the roofline anyway.

A liner is not optional in this state. The Kentucky Residential Code, adopted by the state Department of Housing, Buildings and Construction, says a masonry chimney shall be lined, with a lining suited to the appliance connected to it. The code sets both the minimum and the maximum for one- and two-family homes, and local governments may not swap in another building code, so a flue in Lexington answers to the same rule as one in Nicholasville or Winchester. The linings it accepts include clay flue tile and chimney lining systems listed to UL 1777, the standard for liners fitted into new or existing masonry chimneys. That is why the diameter and the appliance appear on every liner scope: matching them is the code’s requirement, not an extra line on the bill.

Liner kits sold online are often the first prices a search turns up. A kit is the pipe and its fittings. A relined flue is also the camera survey, the sizing, any tile broken out, the insulation, the sealed connection at the bottom, the top-out, and a draft check with the appliance running. The gap between the two is the work.

Your request goes to a single independent firm that works on chimneys and masonry. Ask for its camera to run the flue top to bottom, for the flue to be measured, and to see the footage yourself. Then expect a written scope naming the diameter, insulation, tile removal, the top-out, and a firm figure. If the tiles turn out sound, the scope should say so. A crown or joints gone soft go on the brick and mortar side of the same scope, so one setup covers both.
