We put off this fireplace makeover for way too long! I had to do some serious convincing when I first suggested painting the red brick, but once my husband saw how a simple white paint job gave this dated focal point new life, he was totally on board! From there, an upgraded rustic overmantel to play up the farmhouse charm took things to the next level.

In just ONE day using materials from the home improvement store and my step-by-step DIY guide, see how we created a showstopping, modern-yet-cozy new heart of the home overmantel for only $225. I’m so in love with this transformation and you will be too!

Dive into the details and prepare to get inspired to DIY your own fireplace fabulousness faster than you can imagine!

In its original state, the space featured a conventional brick fireplace with a modest mantel (first photo). Our revamped version unfolded across two projects: painting the brick and expanding the mantel. The second project, highlighted in this post, showcases the addition of a shiplap overmantel in just one day.

About this Post

In a previous post, DIY Painted Brick Fireplace Before and After (with new DIY Mantel) I covered painting the brick and how we built a new mantel. In this post, I’m focusing on our one-day shiplap overmantel build which was the last step in one of my favorite DIY projects to date!

About this Space

This mantel sits on the outside wall of our living room. Our living room has a cathedral ceiling that at its highest point measures approximately 18 feet high. Due to the high ceiling, the builders of our home built a fireplace that sits higher than the norm. According to this informative article by www.pickHvac.com the average mantel height is 52-56 inches from the floor. Our mantel was built 66 inches off the floor to assist in making the fireplace in scale with our high ceilings.

Even with this higher-than-usual fireplace, there was still a significant amount of wall space above the mantel that looked off and was quite frankly hard to fill. This is where our idea to add a panel – or overmantel came in. We wanted to extend the fireplace with a more substantial, decorative look that would fill in the odd empty wall space and put the finishing touches on our previous outdated fireplace.

About Overmantels

I’ll be the first to admit that I had never heard the term “overmantel.” I had always described ours as an over-the-mantel panel but overmantel makes sense. The basic definition of an overmantel is “a decorative structure or an ornamental panel situated above a mantelpiece” and with a little research, I learned these date back to Europe where they were seen in more ornate homes. Overmantels can be made of wood like ours, stone or tile, or plaster. Some are elaborate, and some are simple with a smooth finish which gives a more contemporary look. All are made to enhance a home and become a beautiful focal point of your living space. Mirrors continue to be a popular choice to add to an overmantel as they match everything and can make a space look larger.

Paintings are another common choice and in today’s age, many have flat-screen TVs hung from overmantels. Sconces are often added to overmantels as well. Below is our fireplace decorated for Christmas with my DIY candle sconces.

Regardless of what you choose to hang on your overmantel, the fact remains overmantels help make your mantel more decorative and define the space.

Building our Overmantel for this DIY Updated Fireplace

With our red brick fireplace painted and the extended mantel done, we moved to the overmantel starting with shiplap. We decided we wanted the width of the panel to match that of the mantel base (box below the decorative top). To do so the first step was to plan the width of the panel frame and then cut the shiplap to fit that frame. Below is a photo of the finished overmantel to show how the overall width aligns with the box and the top of the mantel extends beyond both the box and the panel. You can also see we designed the decorative crown molding on the top of the panel to line up with the mantel top.

The width of the frame is 3.5″ (x’s 2) and the length of the shiplap boards measures 56″ resulting in the entire panel measuring 63″ (frame +shiplap+frame). The crown molding with the decorative flat piece is 69″ long.

Tools and Materials for this DIY Updated Fireplace with Shiplap Overmantel

Tools:

• Ladder (we used a gorilla ladder)
• Drop cloth
• Tape measure
• 48″ level
• Miter Box Saw
• Safety goggles
• Nail gun (finish)
• Finish Nails
• Paintable Caulk
• Caulking gun
• Painters putty
• Quart of paint ( we used Benjamin Moore latex paint – Chantilly Lace)
• Paint can opener
• Painters bucket tray
• Paint brush

Materials:

(note: we recommend you go to your local lumber store to hand select the best boards you can find)

• 7- 1 x 6 x 8ft Primed Shiplap
• 2 – 1 x 4 x 8ft Primed pine boards
• 1 -2 3/4″ x 8ft Crown molding
• 1- 1 x 4 x 8ft Primed pine boards top piece

Tip: if you decide to buy boards that are not primed, plan to prime them before painting.

Step-by-step Instructions

Prep:

• Clear the mantel and lay down a drop cloth to protect the floor.
• Set up your ladder and gather your tools.
• Set up the miter box (we tend to cut outside. Be sure to remember your safety goggles)
• Measure and make your cuts on the Miter box starting with the shiplap. You may decide to cut in sections (ie first shiplap, then frame, then crown molding). Our mantel and the overmantel crown molding measure 69″ across. The shiplap panel (with the frame) measures 63″. The overall height of our overmantel is 42″.

Build:

• Using your level as a guide and starting directly on the mantel, begin installing the shiplap. Attach the shiplap to the wall using your finish nail gun. Place a nail through the top and bottom of each shiplap board. Below you can see the progression of the shiplap installation.

• Once the shiplap has been installed move to the frame. Use the 1 x 4 x 8ft Primed pine boards and cut them to fit around the shiplap panel. Extend the top portion of the frame to have a base to attach the crown molding. We used scrap pieces of 1 x 4 x 8ft Primed pine boards to build this extension to cut costs. (see the second photo below)

• Next move to the crown molding. We plan to devote an entire post to DIY crown molding. In the meantime, Home Depot has you covered in this post that includes videos.

Paint:

• Fill the nail holes with painter’s putty, and use a wet rag to wipe off the excess. If needed sand the putty once it has dried.
• Seal the seams and around where the overmantel meets the wall with caulk. We use a caulking gun and a wet rag to remove the excess. Let dry.
• Using a paint brush paint the overmantel with two coats of latex paint, allowing the first coat to dry before moving on to the second coat. We used Benjamin Moore interior latex paint in semi-gloss. This is the same paint we used on the brick and new mantel. It is also the same paint that is on our living room woodwork.

Frequently Asked Questions About This DIY Updated Fireplace

Decorating our Fireplace Update

This newly revamped fireplace is one of my favorite places to decorate. I DIY’d this fireplace cover and love the way it looks. Don’t worry it slides right off for when we want to use the fireplace! On the raised hearth I typically put fun storage baskets holding firewood and our dog’s toys. On the mantel, I will often use a collection of candles, books, and plants or flowers. This heavy antique mirror stays put and I have fun decorating around it.
