Your fireplace hearth, repaired and measured in Summerport Beach

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 hearth in a fireplace that has sat unused

A fireplace left unused for years often has a hearth that became a shelf, a plant stand or a spot for a television. Loose tiles and cracks can go unnoticed under those objects.

Before the first fire in a long time, we clear the extension, check the finish and the base, and confirm the size against the opening. Any repairs go on a written list, and chimney and firebox checks are scheduled as their own service if they are due.

• Extension cleared and checked
• Finish tapped and looked over
• Size confirmed against the opening
• Chimney and firebox checks booked separately if due

A yearly look at the hearth

NFPA 211 puts chimneys, fireplaces and vents on a yearly inspection. The hearth is part of the fireplace, and a yearly look catches loose tiles and open joints while they are small.

Between visits, a quick check at home helps. Look for tiles that rock, grout that has fallen out, a gap at the firebox edge and marks on the floor past the extension, and mention any of them when you book.

• Tiles that rock
• Missing grout
• A gap at the firebox edge
• Marks on the floor past the extension

How heat reaches the floor through a hearth

Heat moves through solid material, so a thin or cracked hearth passes more of it toward whatever lies below. The code's thickness rules and some manuals' insulating layers exist to slow that path.

When we find scorched or darkened material at the edge of a hearth opening, we treat it as a sign that heat has been getting through. The repair restores the thickness and the layers before the finish is replaced.

• Thickness restored
• Insulating layers rebuilt where a manual calls for them
• Finish replaced last
