Installing a Mantel: 5 Easy Steps 

Installing a mantel on drywall is very simple and straightforward. Anyone with a basic guideline should be able to install a mantel themselves.

Mantels are made from a variety of materials. Including marble, limestone, granite, and fine wood. They’re usually flat on top. 

Decorations like lanterns, watches, and framed portraits may be placed on top of them. Mounting a mantel is similar to installing a damper.

These are some mantels I have handpicked on your behalf:

The method I’ll be showing should work for any usual mantel you can find. 

Without further waiting, let’s jump to the interesting part!

Step 1: Assemble the Mantle

If the mantle does not arrive pre-assembled, you will have to put it together. Many mantles just require the use of screws or wood nails to secure the feet to the shelf. Because processes differ by product, follow the manufacturer’s instructions for this part.

Step 2: Place the Mantel on the Wall

Place the mantle on the wall where it will be installed. Because of its weight, you may require assistance lifting the mantle from the ground and securing it.

Step 3: Trace the Outlines on the Wall

Draw a line from the mantel shelf to the wall. Marking the height of the mantle with a pencil mark on the wall. 

Then return the mantle to its original position on the floor.

Step 4: Find Studs Using A Stud Finder

Detect the studs inside the drywall following the line you drew using a stud finder. Every time a stud crosses the line you created, mark the middle of each stud using a pencil.

Step 5: Nail the Mantel to Secure its Position

Return the mantle to its original position. Drill a pilot hole in the shelf and drywall using a drill bit. Hold your drill at a 45-degree angle downward. 

Using a nail gun or hammer, insert a finishing nail into each of the pilot holes. 

The nails should be deep enough to go at approximately 1 inch through the drywall. Make sure the wall doesn’t get hot when the fireplace is on.  The mantle will be held in place by these nails.

Finally, your mantel installation is complete.

Tips on Installing A Mantel

Here I have some tips and tricks for you to make your mantel installation better. These should help you along the way.

Tip 1: If you’re not certain that the nails on the shelf will keep the mantle in place, repeat the operation along each leg. A nail can be hammered into the studs where they connect with the feet.

Tip 2:A cleat is a piece of wood fastened to the drywall. It is provided by some mantle makers. The mantle is then suspended from this cleat, with the wood supporting the weight rather than the drywall.

How to Replace A Mantel from Drywall in 6 Steps

If you want to replace your existing mantel, you’ll probably have to take it down first. It’s as easy as putting up a mantel. Some people may even find it simpler. But it’s a different scenario if it’s a double-sided fireplace.

Step 1: Remove the Corbel Bracing

If there are corbel bracing under the mantel, remove them. Under the mantel, corbel braces are pretty big. 

Frequently used as decorative supports. Stone, wood may be used.

Step 2: Chip Away the Masonry

They use a cold chisel and masonry hammer to chip away the masonry surrounding stone or brick corbels. Pry the corbels out with the top of a pry bar. 

With the hammer, knock the pry bar to make a small hole. Remove them by gently prying them loose.

Step 3: Unscrew Screws From Wooden Corbels

Using a drill driver, unscrew screws from wooden corbels. If the corbels are secured in place by bolts, remove them with a socket and ratchet. 

In case no screws are visible, chisel them out to reveal the screws.

The screw holes may be filled with wood filler, use the chisel to chip the filler away, revealing the screw heads and removing them. If required, knock the corbels using the hammer to break them and remove them.

Step 4: Loosen the Mantel

Now you have to loosen the mantel. Push it upward and move it up and down. If required, use a rubber mallet to dislodge it from the bottom.

Step 5: Pry off The Mantel

Pry the mantel off with a pry bar from behind. There might be a ledger inside or beneath it if it won’t come off. The ledger is a wall-mounted connecting board that is screwed or fastened in place. 

Using the drill driver, locate connection screws and unscrew them from the mantel. 

Step 6: Dislocate the Mantel

Using the pry bar, pry the mantel away from the wall. If required, remove screws from the mantel and discard them. Finally, dislocate the mantel from the wall.

If you follow my guidelines thoroughly this should be a piece of cake.
