Hearth repair in Clear Lake

When a raised firebox allows a thinner extension

The same code section carries an exception. Where the firebox opening starts 8 inches or more above the top of the hearth extension, a 3/8 inch layer of brick, concrete, stone, tile or other approved noncombustible material is thick enough for the extension.

Many raised fireplaces qualify and many flush ones do not. We measure the height from the extension to the bottom of the opening before recommending a thin replacement finish, because the tile that is fine in front of a raised firebox can fall short in front of one set at floor height.

Hearths that are used as a seat or a step

A raised hearth often doubles as a seat, or as a step up to the mantel shelf. That use puts concentrated weight on the edge, which is exactly where thin tops and unsupported corners crack.

The residential code expects hearths to be reinforced to carry their own weight and all imposed loads. When we rebuild a hearth the family sits on, we plan the support for that use and tell you what the finished edge is built to take.

Hearth protection for a wood insert

A wood-burning insert changes the fireplace in front of it. Insert manuals set their own hearth protection in front of the unit, and those figures can be larger than the fireplace's original extension.

When an insert is in place or planned, we read its manual alongside the code before sizing a hearth repair. The extension then covers both requirements, and you avoid rebuilding the hearth a second time when the insert goes in.

• The insert's own hearth figures
• The code size for the fireplace
• An extension planned to cover both

Condominium and association hearths

In a condominium or a community with an association, the hearth may belong to a unit that shares walls, chimneys or rules about visible changes.

We suggest checking with the association before choosing a new finish. The repair itself follows the fireplace and the code, and our written scope gives the association a clear description of what will change and what will stay.

• Association rules checked first
• A written scope for approval
• The repair itself follows the fireplace and the code
