5 Door Installation Mistakes You Should Avoid

Door installation might sound like a simple DIY project, but it has many small details that you should not overlook. Failure to do so will have you dealing with an array of unexpected problems that will only make the installation process more frustrating. Here are the five most common door installation mistakes you should avoid.

1.   Not getting the correct measurements

Taking proper measurements is the most critical step in your door installation project, and it calls for high accuracy levels. You will need a measuring tape and proper leveler for accurate measurements before ordering a new door at Remember, you should maintain accuracy to the last millimeter if you want a smooth installation process that will not require trimmings or adjustments of the door frame.

2.   Failure to consider your floors and walls

Too often, DIYers level the door by aligning it with their floors and walls as they assume these surfaces are even or parallel. Unfortunately, this is not always the case, and doing this will leave you with a sagging or misaligned door. If your wall is out of plumb or floors are uneven, you will need to make up for these errors by taking more time during shimming and placing jambs off the floor.

3.   Using the wrong hinge screws or over-tightening them

Using suitable hinge screws for door installation is vital as it dictates how well they will hold the door in place. Screws that are too small will not sustain the door’s weight for too long, while screws that are too big might not correctly fit your hinges. Most doors require 3 ½ inch screws, but you should always consult experts while shopping for the perfect door. Remember to avoid over-tightening your screws, as this will only cause tension to the door frame and cause it to warp. It will also lead to problems in opening and closing your door, calling for a re-installation.

4.   Improper leveling

It is not only essential to have all the right DIY tools before you start your door installation project, but you should master the ins and outs of proper leveling. There is no room for error when you want to install a properly fitting door, and you must ensure that the wall, frame, and door are plumb. Always start with a level sill as it is the foundation to attaining the best results, and check the reveals before installing the door.

5.   Wrong installation process

Before you engage in a door installation project, you will need a handful of useful DIY hacks to make it easier to manage this upgrade. The first step is to master the correct order of installation to avoid problems such as installing hinges and shims to the door rather than the wall first or placing your shims backward. Aim to get the installation right the first time, as correcting your mistakes later can prove to be a costly affair that is best avoided.


Taking on a door installation project is a big step that requires proper management to avoid these common mistakes that can be quite challenging to fix.
