In our new place, the living room has an existing fireplace with a really large, river rock stone wall that runs from wall to wall and floor to ceiling. We are very excited to finally have a house with a fireplace, we’ve always wanted one, but never had one (which is why we built this faux mantel before). One problem though… it was missing a nice wood mantel. We have to have a mantel to decorate for the holidays right? I am a blogger after all… and come on, where else would we hang our socks for Santa?
We wanted to have something that was rustic but simple. Because of the stone, our house lends itself toward a farmhouse/country style so the rustic wood also fits in there! When we started ripping out this wall, it meant we needed a new place for our TV. So, we immediately made designs for our new mantel.
This project however was a whole new beast that we have never faced before, a stone wall…. (or if you have a brick fireplace it is the same deal) We couldn’t just tape the mantel on, so we had to do some research to figure out what to do. Once we figured it all out we wanted to share what we learned with you about installing a wood mantel on a stone wall. This was a little tricky and it required a new tool (a hammer drill) that we really need to add to our tool box.
Here is a list of materials we used:
- (1) 2 x 6 x 8’ pine board (for the ledger)
- (2) 1 x 10 x 8’ pine boards (top and bottom of mantel)
- (1) 1 x 6 x 6’ pine board (middle supports)
- gray stain
- (36) 1 1/2” wood screws
- (12) 1 1/2” pocket screws
- (2) 1/2” wedge anchor bolts
- (3) 1/2” drop anchor bolts
- (7) weathered fence wood slats
- (1) 5/8” x 12” long concrete drill bit
- wood glue (for thin strips of weathered wood)
Cost breakdown of the project $100
- wood = $30
- stain = $10
- pocket and wood screws = $10
- anchor bolts = $50
- weathered wood = free
Tools we used:
- circular saw
- drill
- hammer drill (for drilling through concrete)
- Kreg Jig
- ratchet wrench
- nail gun
Here is a before picture during our move into our new place. Sorry about the mess, heck this actually looks pretty darn good compared to what it was some of the time!
We decided to do an eight foot long wood mantel, that would float above the fireplace.
Here I am posing for the mockup. We are trying to get an idea of how it might look (so we take a picture or two) and how high above the fireplace we wanted it. It was not easy posing for this picture. Hold a heavy eight foot board level from one end isn’t fun. I tried my best though, with all my manly strength.
Here we wanted to see how a layer of old weathered fence wood would look over the pine structure. We were excited to see that it really tied in all to colors of the stone wall. (sorry about the bright lamp, with that wall still in place, there NO natural light at all in the space)
After we found the right height, we leveled a string from wall to wall, to use as a guide where the top of the mantel would go. We also taped where the edge of the mantel would go for reference when we started drilling holes.
The first thing that we needed to do was, anchor a ledger board on the wall with bolts into the concrete wall. Behind the rock wall is the foundation wall. The ledger board required, holes drilled through 4” of mortar and 2” into the foundation wall. (Do not drill into the fireplace flue!!!)
Once the mantel location was decided upon, we had to map out the holes for the bolts. We started with only three, but then added two more, for a total of five. We decided not to drill through the stone, in case we wanted to make any changes in the future. The mortar can be easily patched, but stone? Not so much.
We drilled 5/8” holes in the thickest portion of mortar that we could find within the mantel dimensions. Keeping it in the thick mortar areas, prevented the mortar from chipping away from the stone and keeping the stone nice and secure.
We had to use a hammer drill to get the holes drilled. This type of drill saved my life. We tried to use a regular drill but it took about 10 times as long and it was not easy once we hit the foundation wall. We definitely recommend that you use a hammer drill if you have access to one. (We borrowed our uncles drill THANK YOU!)
Here is a picture of the level that we used. This is a level commonly used in laying out fencing. Also, here is the long 12” long 5/8” masonry drill bit that we had to use to get the hole deep enough.

Below is one type of bolt that we ended up using. It is called a wedge bolt. But they are only 7” long, and we also needed bolts that were 10” long. So, additionally I had to use a drop anchor and a 10” long threaded bolt for those deeper bolt holes. The drop anchor was a little tricky to use, but once I had a system down, it was pretty slick.
To add the blots, you need to clean the hole out with a vacuum to remove any loose debris. Then just tap the drop anchor all the way into the end of the drilled hole. When pushing in the drop anchor, you need to push it in with a metal rod that is the same diameter as the anchor to avoid engaging the wedging mechanism. Once the anchor is in place, you use a smaller rod inserted into the thread portion of the anchor to engage the wedging mechanism, til the anchor is snug. Then you bolt the ledger board in place, with your 10″ bolt that is threaded into the anchor until secure.
As for the wedge bolt, as you tighten the wedge bolt, it creates tension automatically and wedges the bolt snug within the mortar.
Below is the ledger board with two small anchor bolts in place to get it level. Once I had it leveled, I drilled the holes for all the other bolts.
Because the holes were so deep I had to come up with a way to clean out the debris. I used some copper pipe, slightly smaller then the hole, and a funnel to create a vacuum nozzle to push into the hole to clean it out.

Now that all the holes where drilled and the bolts in place, I just had to tighten the nuts with a ratchet.

Here is a close up of one of the bolts, washer and nut, nice and tight.
The next step was to get the middle supports cut and in place. The ledger board was not level vertically, because of the unevenness of the stone surface. That required us to cut the support edges, that where against the wall, at a custom angle on each one. So, I scribed the angle onto the support when it was level horizontally. This made sure the the top of the mantel was level, even though the ledger board was not. Then i just trimmed the board according to the line that was scribed.

Once the supports were cut to length, I used my Kreg Jig to drill pocket holes for a strong tight fit.

This is a picture of the finished ledger board ready for the supports.
Here are the supports in place, 6 1/2” long x 5 1/2” wide. Two in the middle and one on each end.

Here is a picture of the installed top pine board, 9 1/2” x 8’ long. Just drilled through the top to the supports and ledger board.
Clamps are handy when you need an extra hand. All I did was screw the boards to the supports. You can also see here that the mantel sticks out from the wall on the edges, because of the uneven stone surface. We dodn’t mind how it looks, since you can’t really see it from any other angle in the room.
If you really wanted, you could scribe the stones onto the top board and cut it around the stone, for a nice tight fit. That would take a lot more effort, but it is definitely doable.

Here it is all assembled and ready for the weathered wood skin.
We decided to stain it gray, incase any portion of the pine it showed through the joints of the weathered wood. The images below show the sequence of the weathered wood installation.

This is how we decided to miter and wrap the corners. We didn’t have enough wood to cover the top and bottom, but you don’t really see those very much (especially since it is stained to a similar grayish color) and it makes the top easier to dust without getting slivers!
Well here it is in all it’s glory! Just wait until we really get to decorate it for the holidays.
The total dimensions are 8’ long x 10” wide x 7” tall.
Now that the mantel is done and we have a cool place for the TV (away from little greasy fingers and keeping eyesight intact), here is a picture of the wall starting to be torn down, and all the randoms from the dresser the TV used to be on now on the mantel and no I didn’t actually arrange anything to look nice, I just didn’t want the munchkins playing with it
What do you think?
Do you like how it turned out?
Here is a link to our faux mantel that we built in Texas, just in case you didn’t get a chance to see it finished.
That’s one good-lookin’ mantle!
Michele, thanks!
Looks good!! Can’t wait to see more! I love watching remodels unfold.
Thanks Ronda! I believe you and I have similar remodel loving souls for sure!
I am SO glad you posted this because we’re in the same situation. We actually bought a pre-fab mantel a year ago at a yard sale but have been researching how to install it forever and couldn’t find a set of concise instructions! thank you!!
Yay! I am so glad we can help! **just be sure to avoid drilling into the flue, and you should be all set!
Great documentation. I am a huge fan of old wood next to stone too. I need one of those Krag jigs, it looks pretty handy.
Yes, the Kreg jig is worth it’s weight in gold!
Kudos to you – I think it looks great!
Thank you! We are loving having it!
This turned out amazing. I hate the fact that we have no mantel on our stone harth. Pinning this!
Thanks Jen!
That was a big project! It sure looks good. We waited so long to do our fireplace makeover, and I know how much I love it. I bet you are just tickled with this!! Enjoy. It’s awesome
Thanks Shannon! We are happy to have it! I think it might just be a requirement to have a mantel in every future house! They are just fun!
WOW! Looks amazing! Thanks for the instructions!!!! Great post!
Cait
Cait! Thanks you so much!
honestly, it is amazing. What a difference it makes that space – Good Job Justin!
Thank you! I LOVE the difference it makes. The wall is SO vast, and not exactly what I would chose, but the stone is real and nice, and my dad installed it, so it has a nice history. The mantel makes a huge idfference, we will have to see what other things we can do to make the space more exciting
Thank you for the tutorial! I’m actually looking at doing something similar with cross beams on my ceiling! Where did you find the thin weathered wood?
Free on the side of the road! it is just weathered fence wood! Keep a look out, if you see some, people tend to grab it fast.
Thanks for this great overview! I am in the process of doing the exact same thing on my stone wall/fireplace. I had the same issue with the length of the bolts, however I had to use very large toggle bolts in some areas and drop anchors in others. I am also running all the video and power cables through it for the TV mounted above it.
I’ll immediately snatch your rss as I can not find your email subscription link or e-newsletter service. Do you’ve any?
Kindly allow me know in order that I could subscribe.
Thanks.
Janette, here is a link to our rss. http://feeds.feedblitz.com/remodelaholic We would love for you to subscribe.
I would love to do this on a jagged white rock wall. What did you do about the gaps caused by the uneven rock between the wall and mantel?
Thank you,
Melinda
Melinda, I attached the ledger board snug to the rocks. I decided to leave the gaps between the mantel and rock. I could have cut the mantel wood to fit the contour of the rock, but that would have taken a long time. I found that you don’t even notice the gap since we don’t view it from above or below. You can kind of see what I am talking about in one of the small images in the middle of the post. I hope that helps!
Thank you so much!
Thank you so much!
