DIY Wood Mantle

Updating a fireplace? Keep reading to see if a DIY wood mantle is right for you!

When we bought our house, the image I had for our fireplace was so different. There was wood paneling surrounding the fireplace that I figured we would paint, clean up the stone, and be done. However, when we got the keys we noticed light coming in where a section of panel was pulling away from the wall, and there were two distinct sun bleached rectangles on either side of the fireplace. We pulled back the paneling and discovered original windows! Someone had asked how we didn’t notice the windows from the outside. I was slightly caught off guard because I hadn’t thought about how we missed those windows! Those windows face north, the entrance faces east, and when you walk up to the door, you don’t see the windows. The house also sits next to an empty lot that was very overgrown and camouflaged the north side of the house to those on the street. Approaching the house for the first time, we were running a tally of projects in our heads, so that list must have clouded our brains ha ha! When we did walk that side of the house, the leaning chimney must have stood out more than the boarded up windows! Upon removing the paneling, we also saw that the fireplace originally had a bell curve shape and two sconces on either side; there were outlines of where these items had previously been. A leaning chimney and messed up fireplace lead our vision to a whole new place!

Fast forward a few projects, like laying new brick, building out the bell shape, installing the insert, laying tile etc, and we come to the mantle. At first we really liked the clean look of the completed fireplace, but our first Christmas in the house was coming and I really wanted to hang our stockings on a mantle! After looking at ready-made mantles for sale online, we did not see anything we loved. We decided to make our own using sources found at a bigbox home improvement store. It turned out cheaper than those we first saw and it was the exact look and size we wanted.

A before and after! As I mentioned earlier, before even considering the mantle, there was a ton of other work to do. This comparison shows some of the changes we made to the fireplace and the living room in general. Let’s get back to the DIY mantle, shall we?

A few corbel examples found at our local Home Depot.

I came across unfinished corbels in my mantle search and asked my husband if there was a way to use them for our mantle. There are many corbel options online. Just type “corbel” in your search engine and a ton come up. You can choose from very simple designs to intricately carved pieces with faux aging. We went with something fairly simple that we found online at Home Depot.

Some materials used to create our DIY mantle.

While planning the mantle shape, we were also thinking of a stain color. At the time, we had no trim around our discovered windows. The other windows in the room had old, chipped white trim. We had purchased a new front door that had been stained a medium to dark color. I attempted to match that color as best I could. Color matching stain is always tricky with different wood species. On that note, I should mention that all the wood we used was red oak. The corbels and trim pieces were actually ordered online because our local Home Depot didn’t have them in red oak.

I used a blend of MinWax wood stains in Honey and English Chestnut to get our desired color. We later matched the window trim to this color too.

Other materials not pictured: 220 grit sandpaper or sanding block, nail gun, air compressor, table saw, drill, screws, nails.

Some oak planks that could potentially be made into a mantle.

Hubby got creative and researched types of wood to use. He found some red oak planks in 1″ x 6″ and 1″ x 4″ and cove trim pieces that would pair well.

Testing out the length of our mantle shelf and how it will look on the corbels.

We centered the corbels on the “column” pieces, cut one oak plank to the length of the entire fireplace, and cut a second plank piece one inch shorter. The second oak plank was placed centered under the first oak plank.

Once we had the layout we wanted, we measured two times for accuracy’s sake, and then made the cuts on the table saw. I wasn’t able to take photos of the cutting process; must have been chasing our son or doing laundry or who knows! Thank goodness for a table saw. How did carpenters of yore build entire houses with hand tools?!!?

Once the planks were screwed together, the trim was measured and cut. The trim wraps around the lower plank, providing some visual interest. 18 gauge finishing nails were used in the nail gun.

Nailing the trim to the mantle shelf.

With the planks and trim secured together to form our mantle shelf, I stained them, as well as the corbels.

The corbels came with mounting hardware, but my husband used self-drilling drywall anchors.

With the stain dry on the mantle shelf, it was screwed into the corbels and the wall. Our mantle was done in time for that first Christmas in our home! It was also the first Christmas we celebrated away from our parents and other family, so for me, hanging our stockings was a small comforting reminder of holidays past.

According to my husband, this is an easy project. I would preface this by saying it’s easy if you have some carpentry experience and if you have the tools, like a nail gun, air compressor, table saw and drill.

Hi I'm Marie! I started an Instagram account to document our relocation and renovation. I realized that I had more to say than would fit in an IG caption, so I started this blog! We are currently living in a 1929 Tudor in Seattle; hubby (makes the projects happen), our kiddo & our kitty. If you like old homes, vintage home decor, and DIY this site is for you. Hope you enjoy!
