Damaged exterior door.

Do you have gaps around your door? What about gaps under your door or door bottom? Even if you can’t see a visible door gap, do you have a drafty door? 

Your front door can boost your home’s curb appeal and make or break a first impression, but it’s also your home’s first line of defense against the elements. Have you noticed any of the following?

  • A door gap resulting in light under the door or peeking around the edges of the door.
  • A visible door gap between the door and door frame.
  • A drafty door with chilly drafts/air blowing through your entryway.
  • Water leaking from the top of the door frame.
  • Water leaking around the door or water leaking under the door or door bottom.
  • A sticky or stuck door that makes it difficult to close or open the door.
  • Bugs crawling under the door and critters in your foyer who have no business being there!

The bad news: You have gaps in your front door.

The good news: You have several options for a proper door gap fix, and protecting your home! We’re going to review how to seal and fix a gap in your door system.

Signs of Alignment Issues

Signs of alignment issues:

  • The door catches or gets jammed when you try to open or close it
  • More light shines through one side of the door than the other
  • The gap across the top is uneven

Wear and tear on older doors can eventually cause your front door to sag, which means it falls out of alignment with the frame. You can fix this issue by tightening the hinges.

If tightening the hinges still doesn’t correct the gap around the top and sides of the front door, you can remove the screws and adjust the alignment. While you’re adjusting or shimming the hinges, replace the old screws with a slightly larger size to reinforce the hardware and prevent the door from shifting or sagging again.

Weatherstripping

Incorrectly installed or worn out weatherstripping can cause gaps in exterior doors which expose your home to drafts, leaks, and bugs. Keep the outdoors on the right side of the door by installing new weatherstripping.

There are several options for sealing gaps in your front door:

  • Felt rolls
  • Corner pads
  • Sticky foam tape
  • Tubular rubber, vinyl, or silicone
  • Kerf Weatherstripping

If you already have an old weatherstripping system on your door, remove the weatherstripping and wash the door frame with rubbing alcohol to remove any remaining residue. Cleaning the door frame will help the new materials adhere properly and create a secure seal. Be sure to install it correctly and prevent future headaches and check out our six-step guide to easy weatherstripping.
