How to install a steel front door 

A steel front door must be properly installed to ensure that your home is both well protected and energy-efficient. Featuring steel interior frames reinforced with extruded aluminum, GIT steel doors deliver outstanding durability and heightened security compared to all other types of doors on the market.  

This guide will take you through all the steps required for installation, to help you complete this task simply and effectively. 

Step 1: Inspect the door 

Inspection 

Following delivery and before beginning installation, take the time to carefully inspect your new steel door. Make sure no damage, such as dents, scratches or deformations, has occurred during shipping and handling. To ensure a successful, durable installation, an intact door is essential. 

Step 2: Prepare the opening 

Frame the opening 

The dimensions of the opening must be one inch wider on either side and one inch higher than those of the door. That extra space will allow you to add insulation and optimize adjustments.  

With a tape measure, calculate the height and width of the opening in several places. This way, you can check that the opening is uniform, with no major variations that could lead to problems during installation. 

Clean the opening 

Next, it’s very important to clean the rough opening: remove all debris, dust and residue that could prevent a proper fit and installation. A clean, dry opening will help ensure that the door fits perfectly and operates properly. 

Step 3: Prepare the door 

Add shims 

Before fitting the steel door into the opening, you’ll need to support it by inserting shims. Position shims at the bottom and on each side of the frame to keep the door in place during installation. The shims will also create the necessary space to add insulation around the door.  

Make sure the shims are correctly positioned and sturdy enough to support the weight of the door without anyone needing to hold it in place. This will make it easier to level the door and ensure a stable, secure installation.  

Step 4: Install the door 

Fit the door into the opening 

With preparation now complete, it’s time to fit the steel door into the opening. Centre the door so that it will not move during installation. Make sure the door is plumb (vertical) and perfectly centred in the opening.  

Use a bubble level to check that the door is perfectly level (horizontal) and plumb (vertical). This adjustment will help ensure that the door operates properly for a long time. Adjust the bottom shims until the door is perfectly level.  

Once the door is set (properly positioned), secure the frame in place using three screws on each side. (Important: never screw the frame into the door head or sill.) Next, tighten the screws so that the door hangs firmly in place but any necessary adjustments are still possible.  

Step 5: Fasten and adjust 

Seal sidelights/transom 

If your steel door includes sidelights or a transom, these need to be properly secured. Apply silicone sealant between the glass and frame: this will prevent air and water infiltration while holding the sidelight/transom firmly in place. Make sure to apply a uniform bead of sealant for optimum air and water tightness.  

Reinforce around the handle 

Strengthen the area around the door handle and lock by using shims. Place shims close to where the handle is to ensure greater stability and keep the door from moving over time. This will help ensure the door operates smoothly and securely.  

Solidify the top hinge 

The topmost hinge has to support a lot of the door’s weight, especially if it is heavy (e.g., because of a glass insert). Replace one of the supplied screws with a four-inch screw ensure that this hinge is firmly attached: this will help the door remain in place and keep it from sagging over time.  

Insulate 

Adding enough insulation is essential to ensure optimum energy efficiency and airtightness. Fill the gaps between the door frame and the opening with expansion foam (take care not to overfill, as this could warp the frame). Once the foam is dry, trim off any excess with a utility knife to leave a flat surface.  

Step 6: Complete the outdoor finishing 

Install the flashing 

To complete the installation of your steel door, it’s very important to install flashing around it. This finish covering, usually made of folded aluminum, provides extra protection against the elements and improves the aesthetics of the door.  

Position flashing all around the outdoor frame, making sure it completely covers the edges to prevent water and air infiltration. Once the flashing is in place, secure it using finishing nails. Use nails in all four corners to firmly secure the flashing, making sure the nailheads are discreet and don’t detract from the esthetics. 

This exterior finishing will not only provide better protection for your door, but also ensure a polished, professional look.

Preparing the site for installation by GIT 

To help the work go smoothly, here are a few tips for preparing the site before our installers arrive. 

1. Remove vehicles from your driveway. 
2. Move furniture and accessories that are near the work area, like blinds, curtains, rugs, carpets, framed art, decorative objects and so on. 
3. Make sure there is at least 4 feet of clearance in front of the door(s) to be replaced. 
4. If need be, clear snow to ensure a pathway to your door(s), including basement openings if necessary. 
5. Remove any air conditioner units from doors to be replaced. 
6. Remove any security bars/grates covering doors to be replaced. 
7. If you have a pet that could run away, have someone watch it, or make sure to keep an eye on it at all times.

9. Give our installers a number where they can reach you any time, if you can’t be home during the work. 

Note 

You are responsible for contacting your municipality to obtain parking, sidewalk closure or alleyway closure permits, depending on the nature of the work. If the installation requires work at height using special tools, please inform your municipality of this as well, to comply with their requirements.  

You must make sure the work site is safely laid out so that we can deliver and install the door(s). Ensure that there will be parking spaces available over a length of 65 feet in front of your property.  

If need be, we can lend you “no parking” signs. If you aren’t able to use your personal vehicles to block off parking spaces for us, please e-mail your request to us at installation@git.ca.
