Transforming your fireplace into a stunning focal point doesn’t have to be complicated or time-consuming. This easy DIY Fireplace Makeover project can be completed in just one day and can make such a dramatic difference in your entire room’s appearance.

In our previous fireplace tutorial, we demonstrated how to use a simple technique with grout and paint, to whitewash our traditional red brick fireplace. To learn more about this project – read the blog post here. Once we achieved the desired base look, we moved on to the next phase: building a basic fireplace over mantel. This step not only adds visual appeal and completeness, but also creates a stylish space above the fireplace.

Start Your DIY Fireplace Makeover

1. Planning Your Over Mantel Design

Before diving into the construction process, take time to plan your over mantel design. Consider the style and aesthetic of your room, the size and shape of your fireplace, and how the over mantel will complement the overall decor theme.

2. Gathering Materials and Tools

Ensure you have all the necessary materials and tools for the project. This may include wood boards or panels, molding, nails or screws, paint or stain, and any decorative elements you plan to incorporate.

3. Building the Basic Structure

Follow a step-by-step guide or tutorial to build the basic structure of your fireplace over mantel. This typically involves assembling wood panels or boards to create the framework and adding molding or trim for a polished look.

4. Finishing Touches

Once the basic structure is in place, apply paint or stain to match your desired color scheme.

By following these steps and customizing the design to fit your style preferences, you can achieve a stunning fireplace makeover that enhances the beauty and functionality of your living space. Let’s get started with all the details and create a fireplace over mantel that transforms your room into the modern space you’ve always wanted!

The Red Brick – Before we started our DIY Fireplace Makeover x2 (two-sided fireplace)

DIY Fireplace Makeover Supplies:

  • 2 1×6 boards (we used prefinished to decrease the amount of prep work)
  • 1 1×8 board
  • Miter Saw/Circular Saw
  • 2 Inch Finishing Nails
  • Hammer
  • Nail Punch
  • Wood Filler
  • Sand Paper
  • Caulk – White Paintable
  • Painters Tape
  • Paint Brush
  • Paint Roller
  • 1 Quart White Semi-Gloss Paint

Step 1: Starting Your DIY Fireplace Makeover: Building The Upper Mantel

First measure the width of the lower surround or the length of the brick (outside edge to outside edge). This will be the length of your 1×8 board. Cut the 1×8 board and then placed it on the wall using 6 – 2 inch nails and then sink them with a nail punch. *If you can try to find the studs, this will help anchor the board more securely. The 1×8 board will be the anchor for our crown molding, so we left an inch space from the top of the ceiling to accommodate the crown and to leave us with 6 inches of board left below it. If you are not adding a decorative molding, place the board at ceiling height.

*If you decide to finish this look with crown molding, the length of your 1×8 board will also be the bottom edge length of the crown. You will need to have extra length on each side of your crown molding to make your 45 degree angle cut upward.

Next measure the length from the top of the mantel to the 1×8 board. That will be the length of your 1×6 boards. Cut the boards with your saw and nail them in using the 2 inch nails. Finish this step by sinking the nails with the nail punch.

Step 2: Fill in the nail holes

Now that your frame is built, fill all your nail holes with wood filler (make sure its smooth and wipe off the excess). You can also sand these areas to ensure a smooth finish with the boards.

Step 3: Caulk your edges

Next, caulk along all the edges of the boards. Once you have let the caulk dry the appropriate amount of time, line your walls/mantel edges with painter’s tape.

Step 4: Time to Paint!

The last step is to edge all inside space and edges of the boards with the paint brush. Next use a roller to finishing painting the boards and middle wall space. We used semi-gloss paint because it matched the trim finish for the rest of our house. This will require at least two coats of paint.

After 1 Coat of Paint – You are almost done!

The Final Reveal:

In one day you can complete this easy fireplace makeover and transform the overall appearance of your fireplace! This basic fireplace over mantel can be a great base if you want to add more decorative molding (such as crown) or it can be perfect just the way it is, for a more simple elegant appearance.
