  1. Choosing the Wrong Door Size

Imagine buying a door, bringing it home, and realizing it doesn't fit. Frustrating, right? Many people assume all interior doors are the same size, but they're not. Standard sizes exist, but older homes or custom-built houses might have unique door frames. Always measure before purchasing a new door.

  1. Skipping Proper Measurements

One of the biggest reasons interior door installation goes wrong is inaccurate measurements. A small error can lead to big gaps or a door that won't close. Experts recommend measuring the width, height, and thickness of the door opening at least twice before cutting or installing anything. DIY door installations always require adjustments due to incorrect measurements.

  1. Ignoring the Door Frame Condition

A new door won't fix an old, damaged frame. Before installing a door, check the frame for cracks, warping, or rot. If the frame isn't square, the door won't sit properly, leading to sticking or uneven gaps.

  1. Not Leveling the Door Correctly

A door that doesn't line up properly can be a nightmare. If the door isn't level, it might swing open on its own or refuse to close. A simple trick? Use a level tool before securing the hinges. A majority of door alignment issues come from skipping this step.

  1. Using the Wrong Tools

A butter knife is not a screwdriver, and duct tape won't fix a bad fit! Using the wrong tools can cause damage to both the door and the frame. To do the job right, have a drill, level, measuring tape, chisel, screwdriver, and shims handy. Investing in the right tools makes the process easier and more professional-looking.

  1. Forgetting to Check Door Swing Direction

Ever installed a door only to realize it swings the wrong way? It happens more than you'd think! Before installation, decide whether the door should open to the left or right based on the layout of the room. A door swinging in the wrong direction can block furniture, cause inconvenience, and just look odd.

  1. Rushing the Installation

Patience is key. Rushing through the installation often leads to mistakes like misaligned hinges, uneven gaps, or damaged materials. Take it slow and follow each step carefully. If needed, watch a tutorial or ask for help.

  1. Poorly Placed Hinges

Hinges that aren't installed at the right height or depth can cause the door to drag or not close properly. Standard placement is from the top: 7 inches down, from the bottom: 11 inches up, and the middle hinge centered between them. Proper placement keeps the door stable and long-lasting.

  1. Ignoring Weather and Humidity Factors

Believe it or not, weather and humidity can affect interior doors. Wood expands in humid conditions and shrinks when it's dry. If a door is installed in summer, it might fit perfectly, but in winter, gaps may appear. Allow the door to adjust to room temperature before installing to avoid seasonal changes affecting the fit.

  1. Not Testing the Door Before Finishing Up

Imagine finishing the job, only to find out the door doesn't close properly! Before fully securing everything, test the door by opening and closing it several times. Check for gaps, misalignment, or uneven swinging. Fix small issues before finalizing the installation.
