How to Build Steps Off Sliding Glass Door

How to Build Steps Off Sliding Glass Door

Constructing a set of stairs leading up from a sliding glass door is much simpler than it seems. Perhaps, with the aid of an engineer, you may create a sophisticated step. However, a simple staircase may be built without the help of anybody. 

How, therefore, can one construct a set of stairs leading down from a sliding glass door? 

If you want to construct a set of stairs leading to your sliding glass door, you’ll need to begin by determining its dimensions. The plank must be trimmed to size. Tighten the screws to secure the boards to the stringer. Avoid stringers by making separate animation frames for each procedure. Next, make a pilot hole in the door frame for the first step. 

To be honest, this is simply a brief overview of the steps involved. If you want to know the specifics, continue on to the conclusion of the article.


Necessary Equipment:

  • Chalkline
  • Sword saw 
  • Reaching clamps that are at least 18 inches long 
  • Corded Drill
  • Framing Square
  • Hammer 
  • Handsaw 
  • Level 
  • Protective eyewear 
  • Sawhorses 
  • Level indicator 


Supplies Needed: 

  • 2×12 x 12 ft. (3) (3) 
  • 2×6 x 12 in. (1) (1) 
  • Fasteners for decks, 3 inches in length 
  • Riser and tread decking


How to Construct Outdoor Steps from a Glass Slider?

Sliding glass door stair construction begins with material selection. The stairs must be modified so that they fit snugly over the sliding glass door. 

The following is a detailed explanation of how to construct steps leading to your deck from your sliding glass doors. 

Step 1: Determine the size of the space via the sliding glass door. 

Get a measuring tape and place it across the doorway. Take a measurement of the whole width of the door, from one edge to the other. Check the width as well. 


Step 2: Reduce the length of the wooden plank to match the one you just measured. 

When the length and breadth have been determined, the wooden planks may be cut to size. If you’re installing hardwood flooring, you’ll want to have them cut to the precise dimensions you determined in advance. You have the necessary stair parts now. 


Step 3: Attach the wooden boards to the stringer using Screws

When the stair treads have been trimmed, the two stringers should be set up at a little angle. The wooden planks will be held up by the stringers. The stringers must be spaced at a distance equal to the rise of the steps.

The boards are drilled after being placed on the stringer. Accurately position the boards and screw them to the stringers. 


Step 4: Secure the First Wooden Tread to the Stair Nosing 

A single hardwood tread is then vertically screwed into place at the top of your stairs’ approach. Remove the whole stairwell and secure its front section to the end of the sliding door. 

Step 5: Make sure the stairs are horizontal on the Ground

One last thing to do is to make sure the steps are perfectly horizontal. See whether the stairs are even by digging a hole and checking the ground. You may rest easy knowing the steps are straight once you check their alignment. 

Check one last time that the stairwell is safe to use by walking up and down them. Bravo! You made the stairs from scratch, huh?


How Can You Construct Steps Without Stringers? 

You may now construct stairs without the need for stringers if you find working with them to be cumbersome. What you should do is this: 

Step 1: Build the First Step 

You should begin by gauging the dimensions of the first stair. Be sure to save the biggest one for last. First, measure and mark the long edges of the two wooden boards you will be using. Put them together with four tiny, vertically fastened wooden pieces and a few screws. 


Step 2: Construct the Remaining Steps

The subsequent stages must be constructed in a manner similar to the first one. You may compare it to making four or five long boxes. Add two vertical wooden pieces to each end. It’ll strengthen the structure overall. 


Step 3: Link All the Steps

This means that, after the stairs have been constructed, they must be joined together. Screw each step onto the next while maintaining a minimum spacing of 16 inches between them. You may use the area as a place to wander or relax.

Step 4: Reinforce the Structure 

Insert a rod through the gap between the two wooden frames. Finally, put some 12″ GR KS in the middle of each stair’s wood by drilling pilot holes. With this method, the central section of the stairway may be locked and strengthened. 


Step 5: Attach the door’s frame to the door’s side

Let’s move on to the next and most crucial stage now. Grab the stair frame and set it down just below the folding door. A proper fit requires that the top be flush with the door. You should next attach the stair to the house’s studs using drills. 


Step 6: Install the Staircase Railing Top Screws 

And last, lay one or two horizontal wooden planks on each stair. Tighten them to the frame using screws or nails. Carry out the procedures in the correct order, beginning at the top. 

Any leftover decking material or plastic wood inserts might be used to line the area under the stairs. Steps may have their bases fortified in this way.


Managing Pressure-Treated Lumber 

If you want to install wooden steps next to your sliding glass door, these instructions will be very helpful. 



  • Employ stainless-steel or hot-dipped, galvanized screws since they are specifically designated for use with treated timber. 
  • Remember to butt the timber together securely during construction if it is damp, as it usually is after being brought from the store. When it dries, pressure-treated wood contracts. 
  • For a more secure nail or screw connection, drill pilot holes into the board ends before assembling. 
  • When it’s required by the task at hand, choose the wood that is rated for ground contact. 



  • While working with or cutting wood, always remember to use appropriate safety equipment. 
  • When handling treated wood, be sure to thoroughly wash your hands. 
  • Follow the rules of your community while getting rid of sawdust and other trash. 
  • Never use pressure-treated wood for a fire. 
  • When mulching, avoid using wood that has been treated with chemicals.


What are the various deck stair options? 

Spiral stairs, straight stairs, straight stairs with landings, numerous staircases, broad steps, and no steps are the six possible stair configurations for your deck. 


In terms of stairs, what is the optimal design? 

L-shaped stairwell: 

The center landing of these stairways helps to limit the number of steps a person may tumble down in any particular ascent, leading some to conclude that they are safer than traditional straight stairways. In order to catch one’s breath before continuing further, the landing is available. If it’s more convenient for your layout, you may place them at a room’s far corner. 


What’s the current stair fashion like? 

Sleek and Contemporary 

The modern staircase design emerged in the late 2020s and shows no signs of disappearing by 2022. Iron balusters and wood treads have been more popular in the last year. 


Which stair design offers the most value for money? 

Typical Staircase 

Which stair design offers the most value for the money? Without a doubt, the simplest and least expensive staircase to build are a set of straight steps. Building contractors may save time and money by using straight runs of stairs. 


What makes a staircase good? 

Elevation gain or loss The stair slope must be no steeper than 40 degrees and no shallower than 25 degrees. It has to be sturdy and rigid for long-term use. The materials used to build the staircase should be fireproof. Landing The landing’s breadth must be greater than the stair’s width.

Final Words

Taking steps down from a sliding glass door is now a reality. Either approach will work for reading this material from beginning to end. You may utilize any of these step-building strategies to your advantage, regardless of whether or not you like employing stringers. 

Please allow us to provide one little suggestion. If the soil is too soft, a concrete base must be constructed before the stairs may be built. Your stair won’t sink as much if you do this. 

Have fun with the stair construction!
