How to Replace the Firebox in a Fireplace
- The firebox is an essential part of any fireplace, and replacing is difficult -- but it's possible.
- Many fireboxes are made with masonry, even in fireplaces with wooden facades, because stone and brick withstand high amounts of heat.
- Rake out the existing mortar in the firebox with a hand rake and discard it.
- Loosen mortar that does not crumble away easily with a hammer and crowbar.
