Local hearth repair for Bal Bay homes

What the hearth extension in front of the opening does

The hearth extension is the noncombustible floor that runs out in front of the fireplace opening and past its sides. Sparks, rolling embers and radiant heat land there instead of on wood flooring, carpet or a rug. The Florida Building Code, Residential, treats it as part of the fireplace, with rules for its material, thickness and size in sections R1001.9 and R1001.10.

Because it protects the floor, a hearth repair is judged by two questions at once. Does the finish hold together, and does the extension still cover the area it has to cover? Our pros answer both before any tile is lifted.

• Catches sparks and rolling embers
• Keeps radiant heat off the floor
• Marks the zone kept clear of rugs and furniture

Heat marks on the floor beyond the hearth

Discolored wood, shrunken vinyl or a scorched rug just past the hearth edge tell a story. Heat or embers are reaching further than the extension covers.

We compare the marks with the measured extension and the opening size. The answer may be a larger extension, a change in how the screen or doors are used, or both. You get a written explanation of the cause before any repair is proposed.

• Discolored or cupped wood
• Shrunken or softened vinyl
• Scorched rug fibers
• Marks right at the hearth edge

Hot ashes and the hearth finish

Ash shoveled out of the firebox can hold hot cinders after the fire looks finished. One maker's manual has owners carry ashes out in a lidded metal container that closes tightly, and set it down on the ground or a noncombustible floor, far from anything that can burn.

A bucket on the hearth sits on a noncombustible surface, though its heat can still mark some finishes. If an ash container has left rings or cracks, we include those tiles in the repair and suggest a spot for the bucket that the finish can take.

Replacing a manufactured hearth pad

Some fireplaces sit on a manufactured hearth pad instead of a built extension. A pad can crack, warp or lose pieces of its surface.

Before recommending a replacement pad, we read the fireplace's own manual for the size and protection it needs and look for a listing label on the pad. The replacement is chosen to meet the fireplace's requirement, since a pad that looks similar can offer different protection.

• Fireplace manual read first
• Listing label looked for on the pad
• Replacement chosen to match the requirement
