This article provides easy DIY steps to fix big door jamb gaps that occur after installing a new floor. When installing a new floor, it is common for the height of the floor to change, resulting in gaps between the door jamb and the floor. These gaps can affect the appearance of the room and may also allow drafts and insects to enter. However, with a few simple tools and materials, it is possible to fix this issue without hiring a professional.

The first step in fixing big door jamb gaps is to measure the gaps accurately. This can be done using a measuring tape. It is important to measure each gap individually, as they may vary in size.

Once the measurements are taken, the next step is to purchase a door sweep. A door sweep is a flexible strip that can be attached to the bottom of the door to seal the gap between the floor and the door.

After purchasing the door sweep, it is time to install it. Start by removing the existing sweep from the door. This can usually be done by unscrewing it or lifting it off, depending on the type of sweep. Then, cut the new door sweep to the appropriate length using a utility knife or scissors. Make sure to leave a little extra length to ensure a snug fit.

Once the door sweep is cut, place it against the bottom of the door and mark the screw hole positions. Pre-drill the screw holes using a drill bit that is slightly smaller than the screws provided with the door sweep. Finally, attach the door sweep to the door using the screws.

In addition to installing a door sweep, it may also be necessary to adjust the door jamb. This can be done by using a chisel to remove any excess material between the door jamb and the floor. Start by placing a piece of cardboard or another protective material on the floor to prevent damage. Then, carefully chisel away at the excess material until the gap is closed.

It is important to be patient and take your time to avoid damaging the door jamb or the floor.

Once the door sweep is installed and the door jamb is adjusted, the final step is to touch up the door trim. If the door trim is no longer flush with the door jamb due to the floor installation, it may be necessary to trim or replace the trim. This can be done using a miter saw or a handsaw. Measure and cut the trim to the appropriate length, then attach it to the door jamb using a hammer and finishing nails.

In conclusion, fixing big door jamb gaps after a new floor installation can be easily done using simple DIY steps. By installing a door sweep, adjusting the door jamb, and touching up the door trim, the gaps can be effectively sealed, improving the appearance and functionality of the room.
