Hearth repair in Kirkman North

The 2-inch rule for a hearth extension

Hearth extensions in front of a masonry fireplace need to be at least 2 inches thick under section R1001.9.2. The extension is concrete or masonry on noncombustible supports, with reinforcement for its own weight and whatever loads it sees.

A thin layer of tile set straight onto a subfloor does not meet that description. If a past remodel replaced the original extension with something thinner, the repair becomes a question of rebuilding the extension correctly. We explain that difference in writing before quoting any finish.

What a written hearth estimate should list

A useful hearth estimate reads like a plan. It names the fireplace type, the opening size and the extension size, then separates finish work from any base or support work.

Ours also lists removal and disposal, protection of the room, setting materials, edges and transitions, and when the fireplace can be used again. With upfront pricing on each line, you can compare options and approve exactly the work you want.

• Fireplace type and opening size
• Extension size against the rule that applies
• Finish work and base work as separate lines
• Date the fireplace can be used again

How a new finish can change which rule applies

The thin-extension exception depends on the firebox opening sitting at least 8 inches above the top of the hearth extension. Raising the extension with a thicker finish can shrink that height below 8 inches.

When that happens, the extension has to meet the full thickness rule again. We measure the finished height before choosing materials, so a new tile or stone thickness leaves the requirements where they were.

• Firebox floor height measured
• Finished extension height planned
• Thickness rule confirmed before ordering

Scheduling hearth work around your household

A hearth repair can take more than one visit, with removal and preparation on one day, setting on another, and finishing after the materials cure.

We give you the sequence and the expected number of visits before starting, and we keep the fireplace area safe to walk past between visits. If the household has a date to work around, tell us at booking and we plan backward from it.

• Removal and preparation
• Setting the new finish
• Curing
