Prep By Choosing The Area

Before you begin, make sure the area is level and that it’s not near any trees or structures (such as your house). 

The patio door needs to be in an area with good visibility so you can see who is coming and going. You also want to avoid putting it in a high traffic area.

Choose The Materials You Will Need

You will need to choose the right materials for your job. You should take into account the weather and your budget, as well as what kind of tools you have at your disposal. If you don’t have all the right tools, then go out and purchase them before starting this project.

Gather Your Tools

Gather your tools. You’ll need a hammer drill, concrete chisel, concrete saw and tape measure with level attached. 

You also want a screwdriver for making pilot holes in the concrete for your door hardware and caulking gun to fill any gaps between door frame and patio slab after it’s installed.

To complete the job you will need: a utility knife for cutting wood trim pieces; paintbrush for painting the interior of your new patio door casing (optional).

Place The Door On The Patio And Mark It To Remove The Concrete

You’ll need a level, a pencil and tape measure. Use the level to mark the door frame to remove concrete from around each side of it. Use your tape measure to check that the door is square with the patio floor.

  • Make sure that both sides of the patio are level using your level before you install your new patio door.
  • Check that all four corners of your new patio door are even with one another by measuring each corner and adjusting as needed by adding or removing material from underneath them until they’re even with one another at all four corners.

Use A Hammer Drill To Break Up The Concrete

Once you’ve picked out the door and decided where to place it, there are two main ways to install a patio door on concrete:

  • Use a hammer drill to break up the concrete.
  • Use an excavator or jackhammer to remove it. (Or, if you’re on a budget, rent one for an hour.)

No matter which method you use, after breaking through your patio’s surface, you’ll need to drill holes in the concrete so that screws can go through them later for example if they’re holding down decking boards or other materials that sit above grade. 

You’ll also want at least one hole in each corner of your floor joist framing support structure so it doesn’t crack when installing windows or doors later on (this is called “framing out” because it provides structure around where these things will go).

Makita HR2641X18.0 Amp motor, AVT anti-vibration technology, variable speed, SDS-plus chuck
DEWALT D25263K8.5 Amp motor, shocks active vibration control, variable speed, SDS-plus chuck
Milwaukee 2712-201-1/8″ SDS Plus rotary hammer, anti-vibration system, variable speed, SDS-plus chuck
Hilti TE 7-C710-watt motor, active vibration reduction, variable speed, TE-C chuck

Remove Excess Pieces Of Concrete

With the hammer drill, use a masonry drill bit to bore holes into the concrete. These are where you’ll insert your expansion anchors for mounting the door frame to the concrete (the heavy-duty metal brackets that attach to your door frame). 

If you’re installing a patio door system by yourself, consider renting a concrete countertop saw or wet saw this will make it much easier to cut through old concrete.

After drilling holes into the concrete, use a chisel to remove any excess pieces of concrete in your way. 

This is especially important around doors with glass panels because there may be more clearance needed between them and surrounding walls/doors than with standard solid doors; removing excess pieces of rough-cut stone will help prevent any accidents when installing these windows into place later on down this process!

Diamond Blade GrinderVersatile tool with a diamond-tipped blade for grinding and smoothing concrete surfaces.

Remove Dirt And Debris From The Area Under The Door

Before installing the door, you will want to remove any dirt and debris from under the door. Use a broom to sweep out the area and use a shop vacuum or wet/dry vacuum to remove any remaining dust.

Use A Leveling Tool To Level And Stabilize The Door

To ensure that your patio door is level and straight, you’ll need a level. Place the level on the patio surface under the sill of the door and make sure that it reads level in both directions. Use shims to adjust the baseboard if necessary until it reads perfectly straight. 

Once you have your baseboard leveled, use 2 x 4 blocks of wood (or other materials) to raise or lower it until its height matches up with the height of your concrete slab. 

Now that your baseboard is secured to your patio, check again with a long level to make sure that it’s still stable and not leaning away from where you want it.

Measure For The Cement Board And Cut It To Fit Under The Door

After you’ve measured the space between your door and patio, make sure that you cut the cement board to fit. If you’re using a circular saw, be sure to use a level as a guide to ensure that the cement board is cut straight.

Attach Cement Board To The Patio With Concrete Screws

Now that the cement board is on top of your patio, you can attach it to the concrete with screws. First, use the drill bit included in your kit to make holes through one side of each piece of cement board. 

Then, screw a concrete screw into each hole and push down until they are flush with or below the surface of the cement board.

Make sure that both sides of each piece are level before attaching them so that when they’re attached, they’ll be level across their entire surface area as well (this will make everything work smoothly).

Attachment MethodDescription
Concrete ScrewsUse concrete screws to securely attach cement board to the patio surface.
AdhesiveApply a strong adhesive specifically designed for bonding cement board to the patio.
Mechanical FastenersUtilize mechanical fasteners such as nails or screws to secure the cement board in place.
Construction AdhesiveApply construction adhesive to ensure a durable bond between the cement board and the patio.
Anchoring SystemImplement an anchoring system that provides stability and reinforcement for the cement board.

Drill Holes Into The Cement Board With A Masonry Drill Bit

  • Drill holes into the cement board with a masonry drill bit. Make sure you’re using a masonry drill bit and not just any old drill bit from the store.
  • Drill holes every 6 inches or so, making sure to use a level to make sure that the board is straight.
  • Attach cement board to patio with concrete screws, making sure it’s level when you attach it to your patio so that it stays even throughout its lifetime as a patio door!

Once you have leveled and installed the cement board, it is time to install the bottom track. You will need to measure and cut the track to fit around your patio door frame. 

Make sure that this measurement covers any trim on the sides or top of your door frame so that everything is even with no gaps visible from either side of the door. 

There should also be a ½” gap between each side of the track because this will allow for expansion in hot weather!
