How to Reface a Fireplace Surround and Hearth

How to Reface a Fireplace Surround and Hearth

Refacing a fireplace surround and hearth is one of the most transformative home improvement projects you can undertake. A well-executed fireplace refacing project can completely revitalize your living room, creating a stunning focal point that enhances your home’s aesthetic appeal and overall value. This comprehensive guide will walk you through every step of the process, from selecting the right materials to installing your new fireplace components and adding the finishing touches that will make your fireplace the centerpiece of your home.

Selecting Materials for the Surround and Hearth

The foundation of any successful fireplace refacing project begins with choosing the right materials. Your material selection will determine not only the appearance of your finished fireplace but also its durability, heat resistance, and maintenance requirements. Understanding the various options available will help you make an informed decision that complements your home’s decor while meeting your functional needs.

When considering materials for your fireplace surround and hearth, you have several excellent options to choose from:

Material Options

• Natural Stone: Granite, marble, and slate offer timeless elegance and exceptional durability. Granite, in particular, is highly heat-resistant and requires minimal maintenance, making it an excellent choice for both the surround and hearth. Marble provides a sophisticated appearance but requires more careful maintenance due to its susceptibility to staining and etching.
• Ceramic or Porcelain Tiles: These versatile materials come in endless colors, patterns, and sizes. They offer good heat resistance and are easy to clean, making them a practical choice for homeowners seeking design flexibility.
• Brick or Stone Veneer: If you prefer a rustic or traditional aesthetic, brick or stone veneer can provide authentic character while offering easier installation than solid stone.
• Concrete: Modern and industrial, concrete can be stained, stamped, or textured to create a custom look that complements contemporary design schemes.
• Wood for the Mantel: Hardwoods like oak, cherry, or walnut add warmth and traditional charm to your fireplace design.

When making your material selection, consider several important factors. Durability is crucial since fireplace materials must withstand heat exposure and regular use. Heat resistance is equally important—your materials must safely handle the temperatures generated by your fireplace without warping, discoloring, or degrading. Finally, evaluate maintenance requirements to ensure you’re comfortable with the upkeep your chosen materials will require. Granite, for example, is highly durable and heat-resistant, making it an excellent choice for both the surround and hearth, while natural stone generally requires periodic sealing to maintain its appearance and protect against staining.

Steps for Refacing a Fireplace Surround and Hearth

Successfully refacing your fireplace requires careful execution of eight critical steps. Each step builds upon the previous one, so following this sequence carefully will ensure a professional-looking result that will last for years to come.

Step 1: Pry Off the Mantel

Before you can access the fireplace surround and hearth, you need to carefully remove the existing mantel. If you plan to reuse the mantel, mark its outline on both the wall and floor using a pencil or chalk. This outline will serve as your guide when reinstalling the mantel later in the project.

Using sturdy prybars, gently pry the mantel away from the wall. Take your time during this process to avoid damage to the surrounding wall or the mantel itself if you plan to reuse it. As you work, check that all wood framing and lath are at least 2 inches away from the firebox opening, as required by building code. If your existing framing doesn’t meet this requirement, you may need to add additional fireproofing materials or adjust your installation plan accordingly.

Tip: This is an ideal time to consider whether you want to build or purchase a new mantel. A new mantel can dramatically transform your fireplace’s appearance and may better coordinate with your new surround and hearth materials.

Step 2: Remove the Old Hearth

Protecting your floors is essential before demolishing the old hearth. Tape thin plywood or cardboard to the floor surrounding the hearth area to protect it from scratches, chips, and debris.

Using a demolition hammer equipped with a chisel bit, carefully chip away the old hearth and the mortar underneath. Work methodically, removing material in manageable sections. Be careful to leave the concrete hearth base and firebox floor intact—you’ll be building upon these elements.

Once you’ve removed all the old hearth material, brush and vacuum away all debris and dust from the hearth base. A clean base is essential for proper adhesion of your new materials.

Tip: Always wear appropriate safety equipment during demolition work. Eye protection, ear protection, and a dust mask are essential when using a demolition hammer. Consider wearing a respirator if the old hearth contains any hazardous materials.

Step 3: Prepare the Hearth Base

Creating a level, properly prepared base is crucial for successful hearth installation. Start by creating a screed—a leveling tool that ensures your hearth base is perfectly flat and level.

Notch the ends of a 2×4 to create a screed that’s approximately a foot longer than your hearth. The bottom of the notch should fit easily in the excavated hearth area. For a flush hearth installation, cut the notch depth to equal the thickness of your new hearthstone plus 3/8 inch for the thinset mortar layer.

Wet the hearth base thoroughly, then mix and pour concrete topping according to the manufacturer’s instructions. Set the ends of your screed on the floor with the notch facing down. Pull the screed across the hearth base while moving it quickly from side to side. This motion helps distribute the concrete evenly and removes air pockets. Add or remove topping mix as needed, continuing to pull the screed until the base is perfectly flat. Finish smoothing the surface with a trowel. Allow this concrete topping to set overnight before proceeding to the next step.

Step 4: Spread the Thinset for the Hearth

Before applying thinset mortar, test fit your new hearth slab on the prepared base. Use suction cups to lift and position the slab, checking for any fit issues or interference. This dry run helps you identify any problems before you’ve applied mortar.

Mix enough thinset mortar to cover the entire hearth base. Pour the thinset onto the base in an even layer. Using a toothed trowel, comb through the thinset to raise evenly spaced furrows across the entire surface. These furrows help ensure proper adhesion and allow trapped air to escape when the hearth is pressed into place. Save any leftover thinset for subsequent steps where you may need to make adjustments or fill gaps.

Step 5: Set the Hearth in Place

Using the same suction cups you used for the test fit, carefully lift the hearth slab and position it on the prepared thinset. Press down firmly on the hearth to ensure good adhesion between the stone and the thinset layer.

Check that the hearth doesn’t rock or move. If it does rock, lift the hearth and add more thinset where needed to create a stable, level base. If your hearth is meant to be flush with the floor but sits too high, tap gently on the stone with a rubber mallet to compress the thinset and lower the hearth. If the hearth sits too low, lift it and add additional thinset. This leveling process is critical for both the appearance and functionality of your fireplace.

Fill the joint between the firebox and hearth with thinset, then scrape away any excess. Tool the joint smoothly to create a neat, professional appearance that will hide the connection between the hearth and firebox.

Step 6: Set the Surround Pieces

With the hearth properly installed, you can now install the surround pieces that frame the fireplace opening. Using a trowel, comb thinset mortar onto the backs of the side pieces, creating the same evenly spaced furrows you made for the hearth.

Set each side piece in place on top of the hearth and press it firmly against the brick. Ensure that the inside edges of the side pieces slightly overlap the sides of the firebox for a professional appearance and to ensure proper coverage.

Lay a straightedge across the tops of the side pieces and check that they align perfectly. If they’re misaligned, pivot the pieces slightly until they’re perfectly level and aligned. Apply thinset to the top of the surround piece that will sit atop the side pieces. Set this piece in place and press it firmly against the brick, ensuring all joints are flush and properly aligned.

Allow the thinset to harden overnight before proceeding to the next step. This curing time is essential for the thinset to achieve full strength and bond the surround pieces securely in place.

Step 7: Fit the Wood Mantel

If you’re reinstalling your original mantel or installing a new one, careful fitting is essential for a professional appearance. Set the mantel on the hearth, positioning it tight against the new surround and aligning it with the outline you marked on the wall at the beginning of the project.

Measure from the back of the mantel to the wall to determine the thickness of filler strips you’ll need. These filler strips ensure that the mantel sits properly against both the surround and the wall. Cut wood filler strips to the required thickness and glue and nail them to the back of the mantel, keeping them flush with the mantel’s edges.

If you have molding extensions, glue and nail them to the filler strips as well. Using a compass, scribe the strips where they touch the wall and any irregularities in the wall surface. This scribing ensures a perfect fit that accounts for any wall irregularities. Cut along the scribe lines carefully using a jigsaw, then test fit the mantel again to ensure it sits properly against both the wall and the surround.

Step 8: Fasten the Mantel to the Wall

Mark the locations of the wall framing behind your mantel—these are the points where you’ll secure the mantel for permanent installation. Position the mantel so it’s perfectly centered on the new surround. Push the mantel tight against both the wall and the new surround, then use a level to verify that the mantel is perfectly horizontal.

Using 8d finish nails, toenail the mantel into the wall framing at each marked location. Toenailing—driving nails at an angle through the mantel into the framing—provides strong, nearly invisible fastening. Drive the nails carefully, ensuring they go fully into the framing for maximum holding power. Once the mantel is secured, your fireplace refacing project is functionally complete.

Fireplace Refacing Finishing Touches and Safety Considerations

The final steps in your fireplace refacing project involve adding finishing touches that enhance the overall aesthetic and ensure the longevity of your work. These finishing details transform your newly refaced fireplace from a well-executed renovation into a truly stunning focal point.

Grouting and Sealing

If your surround uses tile or stone materials, grouting is an essential step. Apply grout between all tiles or stone pieces according to the manufacturer’s instructions. Once the grout has cured, apply an appropriate sealer to protect the grout from staining and moisture damage.

Decorative Enhancements

Consider adding decorative molding around the mantel or surround to enhance the overall appearance. Crown molding, beaded trim, or custom millwork can add sophistication and elegance to your finished fireplace. Carefully measure and cut these elements, then install them using finishing nails and wood glue for seamless integration with your new fireplace design.

Safety Considerations

Throughout your refacing project, maintain proper clearances between combustible materials and your firebox. Building codes typically require at least 2 inches of clearance between wood framing and the firebox opening. Never compromise on these safety requirements, as they exist to prevent fires.

Ensure that all materials you’ve installed can safely withstand the temperatures your fireplace generates. Use only materials rated for fireplace applications, and never use flammable materials in close proximity to the firebox.
