Fireplace Repair
From the base to the finished edge
Our experts measure the hearth extension and check its support before any material is ordered.
A tile that rocks underfoot
When a tile rocks underfoot, its bond to the setting bed has failed. The cause may be a thin or patchy setting bed, a base that has shifted or a tile that was set without enough support at its corners. Tapping usually finds the hollow sound around it, and sometimes around its neighbours too.
We lift the loose piece carefully and look at the bed. If the base is sound, the tile can be reset or replaced on its own. If the bed is failing across a wider area, we show you and price the larger repair separately, so a small job never grows without your approval.
Where the hearth ends and the firebox begins
The firebox floor, lined with firebrick in many masonry fireplaces, is part of the firebox, and it is repaired as firebox work with materials made for direct flame. The hearth extension starts at the front of the opening and runs into the room.
Damage often crosses that line, for example a cracked extension that continues into the firebox floor. One visit can look at both, and the quote shows which parts are hearth repair and which are firebox repair, each priced on its own line. Seeing the two together also helps with the finish, since the line where the firebox floor meets the extension needs a clean, stable edge.
Why a new finish never goes over a failing hearth
Laying new tile over an old hearth can look like a quick fix, and on a sound, flat base it can sometimes work. Laid over a base that is cracking or moving, the new finish inherits the same problem and usually cracks along the same lines. The extra layer also adds weight to a base that may already be struggling.
It also raises the hearth and changes the edges, which affects the floor transition and, on a masonry fireplace, the thickness allowances. We check the old hearth first and recommend an overlay only when the base is sound and the new height works everywhere it meets.
Hearth repair alongside other trades
Hearth work often happens during a bigger project, with new floors, a new fireplace wall or a painted room. Each trade needs to know where its work stops. A flooring crew may be ready to lay boards the same week the hearth base is curing, and the order of work decides whether the edge meets cleanly.
We agree in writing who prepares the base, who installs the hearth finish and who completes the flooring edge. That way a finished tile edge never waits for work nobody included, and the hearth fits the new room when everything is done. We also check that new flooring keeps its required distance from the opening before it is laid up to the hearth.
