Choosing between tile repair, resurfacing and relining
Flaking clay inside the flue
Moisture and corrosive combustion products can attack the face of clay flue tiles until thin layers flake away. Repair makers call this spalling. The flakes fall to the smoke shelf or the firebox, and the tile wall underneath grows thinner.
We look at how much of the tile surface has been lost and where. Light flaking on a few tiles is a different job from tiles that have lost much of their face. That difference decides whether resurfacing is realistic or whether the flue needs relining, and the estimate says which.
The condition a flue must reach before repair
Repair and resurfacing materials are made for flues that are structurally sound, clean and dry. They bond to prepared masonry and clay, not to soot, glaze or loose pieces. Skipping that preparation shortens the life of the repair.
We explain what your flue needs to reach that condition. Cleaning, removal of loose material and drying time may all apply. Each preparation step appears in the estimate with its own price, so you can see how much of the job is preparation and how much is repair. A flue that is still damp is given time before any material goes in.
Written flue findings for homes in Coral Gate
The findings we give you after a flue assessment in Coral Gate describe each defect: where it is, what it looks like and how confident we are about its extent. They also name the sections we could not see.
That record is useful even if you decide not to repair right away. It shows the next person where to look. If you go ahead, the estimate refers back to the same findings, so the repair can be matched to what was actually found. They also help if another company is asked to quote the same flue.
Changing fuel in a repaired flue
A flue that once carried wood smoke may later be asked to vent a gas-fired appliance instead. Before that change, gas code rules want the old passage checked and its solid-fuel residue removed. The state of the clay lining is a central part of that check.
If a fuel change is planned, tell us before the repair. The repair method has to suit the appliance that will use the flue, and the flue size has to match its manual. The estimate names the appliance the repair was planned for.

Clay flue lining questions, answered plainly
Do you use ordinary mortar to fix flue joints?
No. Flue tile joints call for refractory mortar or a listed repair material made for the inside of a flue. Ordinary masonry mortar and patching compounds break down in those conditions. The estimate names the material used.
Why is there a separate line for removing loose tile?
Loose tile, brick and mortar must be dealt with before repair material goes in, and the effort varies from flue to flue. A separate line shows you how much of the job is preparation and what it costs.
Can you repair a cracked wall between two flues?
That depends on where the crack is and how far it runs. We identify each flue and what it serves, then explain whether the dividing masonry can be repaired or needs a larger approach, listed as its own item.
