How to Build a Stone Fireplace Surround

A stone fireplace surround can add a touch of rustic charm and elegance to any room. Building one yourself can be a rewarding and satisfying project, allowing you to customize the look and feel to your liking. While it requires time, patience, and some basic construction skills, it's a manageable project for experienced DIY enthusiasts.

Step 1: Planning and Preparation

Before you begin, it's crucial to have a clear plan and gather all the necessary materials. This includes:

Choosing the Stone: Consider factors like the style of your home, the size and shape of the fireplace opening, and your budget. Popular choices include limestone, granite, marble, and brick.
Designing the Surround: Sketch out your desired design, including the height, width, and depth of the surround. Decide on the type of mantel you want, if any, and whether you'll incorporate a hearth.
Measuring and Marking: Accurately measure the fireplace opening and mark the wall where the surround will be installed. This will ensure a perfect fit and prevent mistakes.
Gathering Materials: Besides the stone, you'll need mortar, a trowel, a level, a tape measure, a hammer, a chisel, safety glasses, and dust masks. You may also require additional tools depending on the chosen stone type.

Step 2: Building the Framework

For most stone fireplace surrounds, you'll need a framework to support the weight of the stone. This is typically made of wood and should be sturdy and level.

Constructing the Framework: Use lumber that's appropriate for the weight of the stone and the dimensions of the surround. Cut the lumber to size and assemble it securely using screws or nails.
Securing the Framework: Attach the framework to the wall using strong anchors or brackets. Ensure it's securely fastened and level to provide a stable foundation for the stone.
Installing the Hearth: If you're adding a hearth, build it before laying the stone. This can be made of concrete, tile, or stone, and should be level and strong enough to support the weight of the fireplace.

Step 3: Laying the Stone

This is the heart of the project, requiring careful and precise work to achieve a beautiful and durable surround.

Mixing Mortar: Follow the manufacturer's instructions for mixing the mortar. Consistency is crucial, ensuring it's not too thin or too thick, and allows for easy spreading and shaping.
Laying the First Course: Begin at the bottom of the surround, carefully applying mortar to the back of the stone and placing it in position on the framework. Use a level to ensure the stones are level and plumb.
Continuing the Surround: Work your way up, laying each course of stone with mortar, carefully aligning them with each other and the framework. Use a mallet to tap the stones gently into place and ensure a tight fit.
Grouting the Joints: Once the stone is laid, allow it to cure for the specified time. Then, grout the joints between the stones using a grout specifically designed for stone. Use a grout float to smooth and clean the grout lines.

Step 4: Finishing Touches

After the grout has cured, you can add the finishing touches to your stone fireplace surround, enhancing both its appearance and functionality.

Installing the Mantel: If you've chosen to include a mantel, attach it securely to the top of the surround. Choose a mantel that complements the stone and the style of the fireplace.
Sealant and Finishing: Apply a sealant to the stone to protect it from moisture and stains. Choose a sealant specifically designed for the type of stone you've used.
Adding Accents: Consider adding decorative accents like decorative tiles, metal accents, or plants to further personalize the fireplace surround.

Building a stone fireplace surround is a rewarding and visually stunning project that can elevate the ambiance of any room. Following these steps and taking your time can help you create a beautiful and functional fireplace that you'll enjoy for many years to come.
