FAQ

Indoor Fireplace & Firebox Repair questions, answered

Is it safe to use a fireplace with cracked firebrick?

Small hairline cracks are common, but gaps, missing bricks, or loose mortar can let heat reach framing. Get it inspected before using it.

What mortar is used in a firebox?

Refractory mortar rated for high heat. Regular masonry mortar breaks down in a firebox.

Do you convert fireplaces for gas inserts?

We handle the masonry preparation; the insert and gas line are installed by a licensed gas fitter.

How messy is indoor fireplace work?

We seal the room with plastic, use HEPA vacuums, and protect flooring so dust stays contained.

How soon can I light a fire after repair?

Usually after the mortar cures — often a few days, followed by small break-in fires. We give specific guidance.
