Hearth repair in Lake Formosa

Replacing one cracked tile on a sound hearth

A single cracked tile over a solid base is the simplest hearth repair. The tile is cut out without disturbing its neighbors, the old setting bed is scraped back, and a replacement is set flush and grouted to match.

Everything depends on that base being sound. Before promising a one-tile repair, we check the tiles around it and the base under it. If the crack came from movement below, a new tile would only crack again, and we tell you that before you pay for it.

A crack through a single stone hearth slab

A one-piece stone hearth can crack from a point load, a dropped log or movement under the slab. Once it cracks, the two pieces may stay flush or begin to rock against each other.

A tight crack in a well-supported slab can often be filled and left in place. A crack with movement means the slab has to be lifted and re-bedded, or replaced if the break left pieces too small to trust. We explain the choice with the slab in front of us.

• A tight, stable crack filled in place
• A moving crack lifted and re-bedded
• A badly broken slab replaced

Checking the thickness of an existing hearth

Thickness is hard to see once a hearth is finished. A chipped edge, a removed tile or a small test opening shows what lies below the surface and how deep the solid material goes.

We check depth where damage has already opened the surface before cutting anything new. The measurement goes into the estimate beside the code minimum for your fireplace, so the recommendation rests on what is actually there.

• Depth checked at existing damage
• Compared with the code minimum
• Result written into the estimate

Cleaning a hearth without damaging it

Ash, soot and spills are part of a working hearth. Acidic cleaners can etch marble and limestone, abrasive pads scratch glazed tile, and harsh products can wash out grout color.

After a repair we leave you with cleaning advice for your specific finish, including what to avoid. A gentle routine keeps the new work looking the way it did on the day we finished.

• No acidic cleaners on marble or limestone
• No abrasive pads on glazed tile
• Gentle products that keep grout color
