Necessary Materials

Given below is a list of materials that you’ll need to have before starting your fireplace replacement.

  • Level and hammer

Step-by-step Guidelines on How to Replace Fireplace

Step 1: Preparation

Before beginning any project, it’s important to be mindful of the safety precautions that need to be taken. Make sure the fire is out before starting your process and that there are no live electrical wires connected to the fireplace. Keep in mind that you may need to remove and cap off any existing gas lines before proceeding with your replacement job.

Step 2: Measurements

Using a measuring tape, measure the full width, height, and depth of your existing fireplace opening. This is important when you purchase the new surround or mantel so make sure to get accurate measurements. But also be sure to double check any measurements for accuracy before making a purchase. It’s also important to account for any additional items such as a fireplace grate or glass doors that will be added later.

Using a Measuring Tape

Step 3: Removal

Start by removing the existing fireplace surround or mantel. You’ll likely need a drill to remove any screws that may be holding it in place, and you may also need a pry bar if there’s adhesive present. This part of the job can be tricky and requires some patience so it’s important to go slow here. You may also need to remove any existing brick or tile from the firebox, depending on the end result you’re aiming for.

Step 4: Clean Up

Make sure to clean up the area and remove any debris that may have been left behind after removing the old surroundings. It’s important to remove any dust and dirt before beginning the installation of your new fireplace. But be careful not to damage any existing wiring or plumbing that may have been hidden behind the existing fireplace. If anything looks suspicious, it’s best to call in a professional.

Step 5: Leveling

Using a level and a hammer, ensure that you have an even surface before continuing your project. It’s important to make sure your surface is level before beginning the installation of your new fireplace. This will prevent any issues when it comes time to mount the surround or mantel. It’s also a good idea to use the level to ensure any existing wires or pipes are secure before continuing.

Step 6: Cement Board Installation

If you are replacing brick or stone around your fireplace, you will need to install a cement board before proceeding so that it has something to attach to. But be sure to double check your measurements for accuracy before making any cuts. It’s also important to make sure that the cement board is securely attached to the walls so that it does not move when you begin installing the brick or tile.

Step 7: Tiling

Once the cement board is in place, you can begin installing the new tile or brick around your fireplace and begin forming your desired design. Make sure each layer is level before adding more tiles or bricks on top of it. This will ensure that your design is even and will look professional when complete.

Installing the New Tile or Brick

It’s important to double check your measurements for accuracy before cutting any tiles or bricks, as this can have an impact on the overall look of your finished design.

Step 8: Mortar and Grout

Once all the tiles or bricks are in place, it’s time to begin adding your mortar and grout. Make sure that you follow the manufacturer’s instructions when doing so in order to ensure proper installation. Otherwise, you may run into problems later on and where you don’t want them. You may also want to consider adding a sealant to your fireplace once the mortar and grout have been applied for extra protection.

Step 9: Hearth Surround

After installing the tile or brick, you can now begin installing the hearth surround. Make sure to measure and level each part before making any cuts or drilling holes. Otherwise, you may run into issues when it comes time to attach the surround. It’s important to make sure that all parts are securely attached before moving on to the next step.

Step 10: Mantel Installation

Once the hearth surround is in place, it’s time to install your new mantel! Measure twice before cutting any wood and make sure everything fits together snugly. But be sure to double check your measurements for accuracy before making any cuts, as this can have an impact on the overall look of your finished design.

Step 11: Finishing Touches

Finally, add any finishing touches you may have such as fire grates, glass doors, and decorations to complete the look. Always use caution when working around a fireplace, as it can be hazardous if you don’t take the necessary safety precautions. But with a little bit of patience and some hard work, your new fireplace will be complete and ready to enjoy for many years!
