Fireplace Rebuilding
A cracked firebox or crumbling surround is a fire hazard, not just an eyesore. We rebuild fireplaces from the firebrick out — restoring proper clearances, draft, and the look of a centerpiece hearth.
Understanding the work
What fireplace rebuilding involves
A fireplace rebuild can address damaged firebrick, deteriorated joints, or a worn hearth and surround. Decorative changes and combustion-system repairs are different tasks; the plan should make clear which parts are being restored and which remain in place.
Inside the firebox
The firebox takes direct heat from the fire. Firebrick and suitable refractory mortar are used in the combustion area rather than ordinary decorative finishes. Cracks, loose brick, or missing joints deserve evaluation before further burning, even if the surrounding room looks unaffected.
Hearth, surround, and the path above
The hearth protects the floor at the opening, while the surround frames the fireplace. Above the firebox, the throat and smoke chamber connect to the flue. A rebuild should consider the entire path; replacing the visible surround alone does not resolve drafting or liner defects.
Local service
Professional fireplace rebuilding in Salem, OR
Fan Chimney Service & Masonry rebuilds and repairs fireplaces in Salem, Oregon and the surrounding mid-Willamette Valley. We repair cracked firebrick, rebuild fireboxes, restore hearths and surrounds, and parge smoke chambers so your fireplace is safe and looks the way it should.
The firebox takes the most heat and abuse of any part of the chimney system. Over time firebrick cracks, mortar joints burn out, and gaps open that let heat reach the wood framing behind the fireplace. A firebox with open joints or missing bricks is not safe to use until it is repaired.
Some fireplaces only need a few replacement firebricks and new refractory mortar; others need a full rebuild or a new hearth. We explain the difference, show you photos, and give a written estimate before starting.

When a fireplace needs rebuilding
Have your fireplace evaluated if firebricks are cracked or loose, mortar joints are missing, the back wall is bulging, the hearth is cracked, or the damper no longer closes. Summer is the ideal time to rebuild so the fireplace is ready for fall.
What affects the cost of fireplace rebuilding
- Extent of firebox damage
- Firebrick and refractory materials
- Hearth and surround materials (brick, stone, tile)
- Smoke chamber condition
- Access and room protection
- Whether an insert will be installed afterward
Every job gets a written estimate before work begins.
Can I patch firebrick with regular mortar?
No. Regular mortar breaks down under fireplace heat. Fireboxes require refractory materials rated for high temperatures and correct clearances to combustibles.
