How to Replace a Fireplace Surround

Replacing a fireplace surround, or mantel, can be tricky. Follow these tips for successful replacement of the decorative wood surrounding a fireplace.

Things You'll Need

• Tape measure
• Drill
• Hammer and pry bar
• Nails
• Masonry screws
• Scrap plywood for ledger
• Wood filler
• Mortar or caulk

Instructions

Removing the old surround

1. Measure the old surround--inside to inside, outside to outside, top to bottom--and take at least one photo (digital, if possible) before removing.

2. Find the mantel anchors. These can include screws hidden behind plugs or ledger board, a horizontal strip mounted to the wall or fireplace masonry.

3. Remove any side trim, wood plugs, etc. to reveal as many mounting screws as possible.

4. Pry mantel loose only when necessary. You risk damaging the surrounding wall and masonry if you have to pry. If you must, place a flat prybar between the mantel and wall and apply steady pressure. Use a hammer to tap into place if needed.

Choosing a new surround

1. Use measurements to choose a mantel that fits your application. Especially important is the space between the firebox and pilasters and frieze. Most building codes call for a 6- to 10-inch border of tile or brick around the sides and top of the firebox mouth. Purchase a mantel with an opening at least as large as the outside of this border. Trim can be used to make the opening smaller, if needed.

2. Shop your local home center for an excellent variety of pre-made surrounds. Pick something that suits your house. Remember that you will probably be living with the one you choose as long as you own your home. Pick a mantel with a prefinished surface to avoid hassles with stain. If you are building your own, check your local library for manuals and instructions on finishing.

3. Look for tight joints, square corners and smooth finish, free from runs and drips, as signs of quality construction. Once you know the style you want, buy the best quality you can afford to avoid expensive repairs later.

4. There are books and websites filled with free and commercial designs if you are brave enough to build your own.

1. Follow manufacturer's guidelines for installation for best results, and to avoid problems with your warranty.

2. Check to be sure ledger is level and well-centered at the correct height. Attach ledger board using a masonry bit and drill and Tapcon-style anchors. They are simpler and hold better than lead or plastic anchors. Follow package directions for bit size and installation.

3. Use a pin nailer if possible for the cleanest install with less-visible nail holes. Hammer and finish nails will work, too. Fill nail holes with wood filler designed for stained surfaces. Fill gaps around edges with mortar and caulk.
