How to refresh or rebuild a fireplace surround safely: the materials that tolerate heat, the checks to make on an older chimney first, and the questions that separate careful installers from fast ones.
Typical ranges for this work, to help you judge a quote. Each professional sets their own price and terms — ask them to put it in writing before anything starts.
Size is the first factor: a simple surround around the firebox is a small job, while floor-to-ceiling tile or a new raised hearth is a much larger one. Removing old tile or brick facing, repairing the backing, and cutting around a mantel all add labor. Handmade tile, natural stone and large slabs cost more to buy and take longer to set than standard porcelain.
The area right around a wood-burning or gas fireplace gets hot, so the tile, the backing and the setting materials all need to tolerate it. Porcelain, ceramic, natural stone and cement tile are common choices. Behind them should be a noncombustible backer such as cement board, not drywall or wood, and the thinset and grout should be products rated for the job. Ask the installer to name the products they plan to use.
Many Los Angeles fireplaces are decades old, and earthquakes can crack fireboxes, flues and chimney masonry in ways that are hard to see. Before paying for new tile, consider having the chimney and firebox inspected, especially if the fireplace will be used. Tile work is cosmetic; it does not fix a damaged flue, and covering a crack can hide a problem you would rather know about.
Building and fire codes set how close combustible materials, such as a wood mantel or trim, may sit to the firebox opening, and how far a hearth must extend in front of it. Gas inserts and prefabricated fireboxes also come with the manufacturer's own clearance requirements. A careful installer checks these before designing the layout, and some work may need a permit from the City of Los Angeles or your local building department.
Ask what backer board, thinset and grout they will use and whether they are rated for heat. Ask how they will handle the transition to the firebox, the mantel and the floor. Ask whether demolition of the old facing is included and how they will control dust. Look up any California contractor's license number on the CSLB website before paying a deposit.
Tile set over drywall or wood near the opening, standard grout that cracks with heat cycles, and heavy stone set on a wall not built to carry it are the usual causes of failure. Another is a layout that leaves thin sliver cuts at the edges; a good installer plans the tile from the centre of the firebox outwards so it looks balanced.
