Hearth tile and stone repair in Stone Crest

What sits under the hearth matters as much as the tile

Section R1001.9 has hearths and hearth extensions built of concrete or masonry, resting on noncombustible supports, with reinforcement for their own weight plus every load placed on them. The support keeps a heavy slab from settling and keeps heat away from the structure below.

A finish repair over weak support tends to crack again along the same line. When a crack pattern points to the base, we open enough of the hearth to see it and give you the support repair and the surface repair as two separate prices.

Where the hearth meets the finished floor

The edge between a hearth extension and the room's floor takes traffic and shows every mismatch in height. A new finish that is thicker or thinner than the old one changes that edge.

We plan the transition before ordering material, choosing a flush edge, a small bevel or a trim piece suited to the materials on each side. The goal is an edge that does not catch toes or collect ash, and a clear line where the protected area ends.

• A flush edge
• A small bevel
• A trim piece suited to both materials

The ash dump door in the hearth floor

Some masonry fireplaces have an ash dump, a small cast-iron door in the inner hearth that drops ashes into a chamber below. Its frame can loosen in the masonry, and the door can warp, rust or go missing.

A loose or missing ash dump door leaves an opening into that chamber. We reset or replace the frame and door with a fitting unit and seal it into the hearth floor. If you no longer use the ash dump, we can discuss closing it properly as part of the work.

• Frame reset or replaced
• Door replaced with a fitting unit
• Sealed into the hearth floor
• Closed off if you no longer use it

Hearth tiles that have shifted out of line

Tiles that have slid, tilted or opened their joints show movement in the bed or the base. A hearth whose grout lines have wandered is telling you the tiles are no longer held firmly.

We check whether the movement is old and stable or still happening. Stable shifts can be reset during a finish repair. Active movement is traced to its cause first, because resetting tiles over a moving base only straightens them for a while.
