A sticking door can be frustrating, and often, people will simply put up with it to avoid the hassle of taking it off its hinges and sanding down some of the problematic edges.

Whether it’s a door that doesn’t close smoothly, scrapes against the floor, or needs a good shove to open, this problem can become a real nuisance. 

If this is you, fear no more. Fixing a sticking door is often more straightforward than you’d think, requiring just a few basic tools and a little know-how. 

In this guide, we’ll walk you through simple steps to diagnose the issue and offer fixes so you can get your door moving smoothly again in no time.

What tools do I need?

  • Phillips Screwdriver (not a drill)
  • Belt sander or sandpaper & block
  • Hand or Electric Planer
  • Chalk

Steps to Fix a Sticking Door

  • 1. Tighten the screws:

    Loose hinges are a common and easy fix for a sticking door. Use a screwdriver to tighten the hinge screws on both the door and the door frame. Loose hinges can cause a door to sag, sticking as a result.
    Tip: Avoid using a drill, as it can sometimes strip the screw holes.

  • 2. Adjust the hinge:

    Your door might need a little repositioning. Drive a long screw through the door frame into the wall framing. This can move the door by approximately 1/8th of an inch, which may be enough to stop your sticking problem.

  • 3. Adjust the jamb:

    Another way of drawing in the hinge is to try driving a long screw through the latch side of the door frame. This will give the door the extra bit of wiggle room it needs to open and close without sticking.

  • 4. Sand or Plane the door

    If none of the above methods work, you may need to plane the door.  Mark on the door with chalk exactly where it rubs against the door frame, then remove the door from its hinges. We recommend planing the door using a belt sander, hand plane or electric planer. You’ll need to hang the door back on its hinges to check the fit. If this fixes the problem, all you’ll need to do is repaint or stain the sanded area.

Has Your Door Dropped?

A sticking door is often because of a dropped or sagging door. This is usually an easy fix by following the steps above.

What causes a Door to Stick? 

While the above steps are quick ways to fix your stuck door, it will be more beneficial to identify the cause to ensure it doesn’t happen again. Here are the common causes and their fixes:

  • Door Misalignment
  • Door Swelling or Warping
  • Door Sagging
  • Door Not Adjusted for Flooring

Door Misalignment

What It Is

Doors can shift out of alignment over time. It can happen because of changes to the foundation or the doorframe settling. Moving foundations is a more common problem with new homes. As the foundations ‘settle’, the walls can warp, meaning the door frames are no longer straight. Houses are usually built to accommodate this, but any significant shifts will lead to frame misalignment and doors sticking. 

How To Identify

To check if your door is misaligned, close it and see if the top or side of it sits close to the frame. If not, the door might be sticking due to misalignment. You can also use a spirit level to check the alignment of your frame. If it’s not level, your door frame may have shifted out of plumb.

How to Fix a Misaligned Door

Tighten the screws in the top hinge. If the screws don’t tighten because they’re stripped, drive a longer screw through instead.

Door Swelling

What It Is

Wooden doors can naturally swell or warp due to changes in humidity and temperature. If you live in a humid area or your home has excess moisture (more than 70% humidity level), the door may have swelled slightly, causing it to rub against the frame. This is more common during seasonal changes and can also be true for non-wooden doors like PVC, fibreglass or metal.

How To Identify

Your door sticks at the bottom

How to Fix a Swollen Door

Sand or plane the bottom edge of your door, and use dehumidifiers to reduce humidity levels. Investigate where the moisture is coming from for a long-term solution.

If the door is too warped or has excess moisture, you will need to replace it, planing can only help so much.

Door Sagging

What It Is

If the screws holding the hinges to the door or frame become loose or the door is too heavy for the hinges, the door can sag/drop out of alignment, causing difficulty when opening & closing.

How To Identify

Check the hinges to see if any screws need tightening. 

How to Fix a Sagging Door

Tighten the hinge screws on both the door and the door frame. Use a manual screwdriver rather than a drill to avoid stripping the drill holes.

Door Not Adjusted for Flooring

What It Is

If the door was not adjusted when installed, or you've got new flooring put down and forgot to adjust the door, chances are this is the cause of your door sticking.

Flooring comes in various thicknesses, and you may have bought a thicker option than you had before.

How To Identify

Your door drags along the floor, over time you'd see scrapes or scuffs along the floor, especially from laminate and other hardwood types. If you have carpet, it will eventually wear over time.

How to Fix a Dragging Door

Sand or plane the bottom of the door to accommodate the flooring.

Tips for Preventing a Sticking Door

  • Check doors regularly, especially at the start of summer and winter
  • Oil the hinges annually
  • Check for moisture damage and sand down any swollen areas
  • Tighten the hardware 

Door Sticking FAQ's

How do I stop a door from sticking in winter? 

When doors warp or stick during winter, it’s usually due to temperature or humidity changes. Carry out the usual door maintenance by inspecting the door frame and hinges for signs of excessive moisture or loose screws. Use a dehumidifier and tighten the screws if needed to help the door stay secure.

Will a swollen door ever go back to normal?

A swollen door might return to normal when humidity levels decrease. If there has been excessive moisture, which has warped your door too much, no amount of sanding will fix it - it's time to replace your door

Conclusion

A sticking door is a common but fixable problem that most homeowners can tackle with basic tools and a little patience. By identifying the cause – whether it’s loose hinges, swelling, or misalignment – and following the appropriate steps, you can restore your door to smooth operation.
