Before an insert goes into the fireplace

Plans for a fireplace insert often bring the flue into question. Many insert manuals call for a liner run the full height of the chimney, and even where they do not, the existing flue has to be sound enough to carry what the insert sends up it.

We check the flue before you commit. If it is sound, you keep your options. If it has open joints or cracked tiles, you learn whether a repair or a liner fits the insert you have in mind. Planning an insert for a fireplace in Clay Hill? Call (904) 920-5495 and ask our flue pros for a free check.

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.

Gas appliances venting through Clay Hill chimneys

Some houses vent a furnace or water heater into a masonry flue. The water vapor in those gases condenses in a cool flue and wears at the joints wherever the house is.

We check appliance flues in Clay Hill for washed-out joints and for a flue size that suits the appliance.

The mortar that holds flue tiles

The mortar between flue tiles is its own material. Section R1003.12 names a medium-duty refractory mortar that water will not dissolve, made to ASTM C199, and it wants every joint tight and finished smooth on the flue side. Ordinary masonry mortar or a generic patch is not that material.

When a joint is remade or a tile is reset, the same class of mortar goes back in. Smooth joints matter as much as tight ones, because a ledge of mortar inside the flue catches deposits and slows the gases. The estimate names the mortar used for any tile work, so the repair matches what the code asks for.

The gap between tile and chimney wall

Clay tiles are not meant to be packed solid against the chimney wall around them. The code separates tile from brick with a gap of air or insulation, never thicker than the liner wall, supports each tile on all sides and allows only enough mortar to make the joint.

That gap lets the hot tile expand without pushing on the cooler masonry. A flue packed solid with mortar behind the tiles loses that room, and tiles can crack as they heat. When we find a solidly packed flue, it goes on the estimate as a factor in the repair choice, because tiles set that way tend to crack again.

Where the tile passes through the top

Section R1003.9.1 wants the concrete, metal or stone top of a masonry chimney to drip water clear and to meet each liner through a caulked joint. That caulked joint, the bond break, lets the tile move without cracking the concrete around it.

Once that joint fails, rain finds the gap and trickles along the outer face of the tile into the stack, and concrete cast tight against the tile can crack it as they move. On top-tile repairs, we cut the old seal out, check the tile's edge and reseal around it. A tile replaced without remaking that joint tends to crack again at the same place.

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.

Is flue repair cheaper than relining?

When the damage suits a repair, it is usually the smaller job. When it does not, stacking repairs on a failing flue costs more in the end, and we price relining instead so you can compare.
