10 Door Installation Mistakes To Avoid For Your Next Renovation Project


Door installation is a popular Do It Yourself project as it’s fairly simple to do and homeowners with a basic understanding of carpentry often enjoy the project. However, tackling a door installation project isn’t for everyone. The project can be time consuming and if it isn’t done properly, it can lead to doors that allow in air and water and simply don’t do the job of protecting the home. Avoiding these 10 common door installation mistakes can help your own project be a success.

Installing a new door is a fairly straight forward process. That’s why so many homeowners enjoy tackling the project themselves. It’s a fairly simple project and doing it themselves can save money. But many people underestimate the amount of work involved with door installation. In order to install your door correctly, you’ll need some help and you’ll need to take the time to understand exactly what you’re getting into – especially if you’re new at DIY projects.

2. Not Getting Organized Before You Begin

Getting everything you need together before you begin is one of the simplest ways you can make door installation easier. In order to install your new doors you’ll need the following; level, hammer, tape measure, caulk & caulking gun, screwdriver, wood shims, screws for hinges, foam or fiberglass insulation (or weather stripping), a friend to help.

Get everything – except the friend – together and carry it around in a large bucket so that you can easily carry it from door to door.

3. Not Checking Each Door Is Level

As you work, be sure to check that each door is level as you install it. Not checking the level as you perform each door installation can damage the door as well as the door frame.

4. Not Taking The Time To Understand How It’s Done

Before you begin, check online for videos of door installation projects. Being able to see how the job is done will help you plan better and get the job done much easier. Seeing the project being done through video can also alert you to how things should look as well as understanding the process more thoroughly.

5. Forgetting To Measure Twice, Cut Once

Part of the door installation process may require you to cut away areas for the hinges. If this is the case, be sure you measure twice before you cut. This built-in system of double checking is a rule of thumb for carpenters, engineers and contractors for good reason.

6. Not Checking Your New Doors Before Door Installation

Even if you’ve ordered your new doors directly from a manufacturer or bought them yourself, be sure you measure and re-check each door before you begin your door installation project. Even when you’ve done all the measuring yourself, mistakes can be made. Finding out a door isn’t the right size before you begin will save you time and frustration later.

7. Not Cleaning The Surrounding Area

It’s important to clean door jambs and the area surrounding a new door. This helps the door to be installed better and will also help when it’s time to install weather stripping.

8. Not Checking The Door Jamb For Scrapes And Gaps

As you install each door, be sure to check the trim for any gaps, breaks or other problems. These can indicate a door installation which was done improperly and may require more attention.

9. Forgetting To Install Weather Stripping Or Insulation

Depending on your door and door jam, you will need to install either some foam or fiberglass insulation or some sort of weather stripping in order to prevent air exchange or drafts.

10. Not Knowing When It’s Time To Call A Professional

Door installation can be a rewarding Do It Yourself project but, if done incorrectly, it can be a costly liability. Know when it’s time to call on the help of a professional so that your new doors won’t become an eyesore.
