A chimney with no liner inside

Older chimneys are sometimes found with no lining at all, the smoke running straight against brick and mortar. The residential code says a masonry chimney is to be lined, with a lining suited to what burns below it.

There is nothing to repair in a flue that was never lined. The fix is a new liner sized to the fireplace or appliance, which is a relining job, and we tell you so plainly rather than offering a coating over bare brick. Not sure your Keystone Heights chimney has a liner? Call (904) 920-5495 and our flue specialists will check for free.

Keystone Heights is in Clay County. In the 2020 Census, Keystone Heights counted 1,446 residents.

How chimney flue repair runs

Swept and examined
The flue is cleaned, then looked over from the roof and the firebox with a light and mirrors.
Mapped and measured
Each defect is placed by height and wall, and the flue size is checked against what it serves.
Repaired by the chosen method
Top tiles swapped from the roof, damaged sections coated with a listed system, or a relining price when repair will not hold.
Checked and cured
The finished flue is examined from both ends and left to cure before the first fire.

Settling chimneys and cracked tiles in Keystone Heights

Horizontal cracks in flue tiles often follow movement of the chimney itself. The cause is the chimney and its footing, not the town.

In Keystone Heights we check the outside of the chimney before repairing tiles cracked that way.

Movement cracks in flue tiles

Cracks that ring a tile, or step through several joints at one height, often come from movement of the chimney rather than heat. Settlement, a shifted footing or a stack pushed by a roof or a tree can shear the tiles inside.

Before repairing a flue cracked this way, we check the chimney outside for leaning, cracks and separation from the house. If the chimney is still moving, the masonry comes first, and tiles repaired too early may crack again. The estimate keeps the two apart so it is clear which repair addresses the cause.

Resurfacing systems and their listing

Resurfacing applies a heat-resistant coat to the inside of the existing flue, sealing cracks and gaps so the passage is continuous and smooth again. The code accepts lining systems listed and labeled to UL 1777, and some resurfacing systems carry that listing.

A listed system has to be installed exactly as its instructions say, from surface preparation to coat thickness, or the listing no longer applies. We name the system and its listing on the estimate. Resurfacing suits a flue that is straight enough for the tools, sound enough to hold the coat and large enough to lose a little area.

Tiles that have slipped out of line

Flue tiles are meant to be supported on all sides and stacked in line, one squarely on the next. When a tile slips, the joint above and below it opens and the inside of the flue develops a step.

A slipped tile cannot be pushed back from the top, and a coat over the step does not realign it. If the displaced sections are near the top, they can sometimes be replaced from the roof. Lower down, a slip usually means relining. We record the position and size of any step, since that fact drives the whole repair choice.

Before a flue repair is chosen

Can one cracked tile be fixed on its own?

If it is the top tile, often yes, from the roof. A single cracked tile lower down usually cannot be reached alone, so it is covered by resurfacing that section or by relining, depending on the rest of the flue.

Does resurfacing make the flue smaller?

A little, because the coat adds thickness to every wall. We measure the flue and the fireplace opening first, and resurfacing is only offered when the flue will still meet the size the code asks for.
