Showing Your Door the Door: A Door Replacement & Installation Guide

Most homeowners don’t require door replacements too often unless you’re susceptible to break-ins or unlucky. The doors to your beloved castle are probably one of the most critical aspects of construction. Solid and secure entry and exit points are essential. 

There are lots to consider when purchasing door replacements, such as what kind of material, type of lock you will use, the thickness of the door itself and other considerations. Most of us simply keep the same door throughout the life of the house, but if the door requires a change, what are some of the things we should think about, and how would the process take place? This article will go through the nitty-gritty of door replacements and installation so you have a better idea of the process. 


Let's begin with the basics; first, we must decide what type and size the door will be in replacement for the old one. We need to consider a few things: the door type, materials, lock and sizing. 

The first thing you should decide is if you require a slab or pre-hung door, slabs are simply the plain old door that will need to be installed with the pre-existing frame. The pre-hung door comes with its frame as a complete package and is ready for installation. According to a team of commercial locksmiths in Melbourne, if you’re deciding to install the door onto the pre-existing frame, it may not align the components of the frame with the new door. 

Whatever you go for, you have to make accurate measurements. The newly installed door must fit precisely to the opening. If you are not precise with the measurements, you may run into trouble later down the line. It may be necessary to hire a contractor to do the measurements or install the door for you. 

Regarding materials, you can choose between steel, metal, wood or fibreglass. If you’re looking for something less maintenance, you should go for steel, metal or fibreglass because wood requires heavy maintenance. Also, wood is the most expensive material for your new door, so it may not be the best choice for those budget-conscious.

Installing the Door

Once we’ve considered the door and installation type, we’ll proceed with its time to begin the installation. If you’ve opted to do this yourself, you’ll have to follow the following steps.

Remove Old Door and Parts

We need to begin preparation by removing the old door and associated components. To do this, you must start at the bottom and remove the screws up until the top. Remove all the hinge screws and all the screws that hold the door in place. Then once all of these screws are removed, you can remove the entire frame and the interior trim. 

Flash the Frame

Once you’ve removed the old parts, you will need to flash the door frame by using a Z-flashing drip cap placed above the opening. This is used to stop water from damaging the door and generally protecting from the elements. Read the installation instructions first to ensure you don’t miss any details. Ensure that the rough opening is ½ inch higher than the door frame and between ½ to ¾ inches more comprehensive than the door frame. It should be level and square. 

Apply the Sealant

This step is vital to protect the newly installed door; we need to ensure that premium sealant is used so rainwater or melted snow doesn’t infiltrate the home wall. Ensure that the sealant covers the entire surface of the exposed framing where the threshold is and where the exterior trim connects to the wall. 

Complete Installation

You will now need to fit the door firmly into position at this stage. If you removed the door bottom up, you would need to install it opposite, so start from the top and work your way down. You will need to press the unit so it's embedded into the caulk and use a level to ensure it's horizontal.

When this is done, you will need to fasten it slowly and evenly so the door is secure. You will need to use a temporary screw to secure the top of the jamb on the hinge, then check the gaps. The gaps between the door and frame must be even. At this point, you would also want to check that the lock is installed correctly and in place; this is vital so the door can open and close properly; it is recommended that you call a commercial locksmith if you want professionals to handle the job. 

Once everything is in place, you want to double-check that there are no excessive gaps; if so, you can shim it tighter. Now that you’ve completed this final step, you’ll just need to go over and add any more sealant if necessary. Then there you have it; your door is installed.
