How to Fix a Door Knob

If your door knob has become loose and you are finding that when you are using it, it now spins helplessly in your hand?

Here's a quick read to help you get it back to functioning correctly.

A common issue due to heavy use, that little wobble isn't just annoying—it can also cause further issues with a door’s mechanics if not resolved as soon as it is noticed. But here’s the great news: fixing it is easier than you might think. and can take the same time it does to brew your morning coffee and make some toast. And yes, if you are relatively good at DIY it is possible to do the repair yourself.

Here’s your step-by-step guide to resecuring your door knob, so that it will return to functioning properly.

What You’ll Need to Make The Repair

Before you dive in, make sure that you have these essential tools to hand:

•    Screwdriver – Phillips or flathead, depending on the type of screw. 
•    Allen wrench – For tightening and loosening those sneaky hidden screws. 
•    Replacement screws – Just in case any are stripped and for a more secure hold. 
•    Thread-locking adhesive – a clever glue which gives a soft hold. Allowing for minimal movement

Pro tip: Having your tools laid out makes the whole process feel way less “DIY panic” and more “I got this.”

What to Do Next

Step 1: Know Your Knob

There are many different types of door know, which are fixed in place differently. To make the repair easier, check the positioning of the screws before you start. 
•    Visible screws: Easy to spot and tighten. 
•    Hidden screws: Sneaky little set screws that might need an Allen wrench. 

Pro tip:  Doing this quick check will avoid error later on.

Step 2: How to Tighten the Screws

Visible Screws:

1.    Locate the door screws on the faceplate.
2.  Tighten each one carefully with your screwdriver until the knob feels solid.

Hidden Screws:

1. Look for a small hole or slot on the side.
2. Insert the Allen wrench and turn clockwise until the screw feels snug and secure.

Step 3: Carefully Secure the Base Plate

An unsecured base plate can affect the door knob when it function – because the plate holds it in place.

To make sure it's more secure:

1.    Remove the knob from the spindle. 
2.    Tighten the screws securing the base plate to the door. 
3.    Pop the knob back on and secure it.

Note: If you find that the door knob is still loose you will also need to check the spindle

Step 4: Check the Spindle

The spindle connects both sides of your knob. Over time, lots of regular use can wear the spindle down and therefore it may need to be replaced. To check this:

1. Unscrew and remove the knob and base plate from both sides of the door.
2. Inspect the spindle for damage or wear. This can be replaced at relatively low cost if needed.
3. Reinstall the base plate and door knob, ensuring all screws are tightened properly.
   

Step 5: Add Optional Extra Security

For high-use doors, a dab of thread-locking adhesive will ensure the repair is more effective and prevent the door screws from loosening over time.

1. Remove the Screws: Take out the screws holding the door knob or base plate
2. Apply Adhesive: Apply a small amount of thread-locking adhesive to the screws.
3. Reinsert and Tighten the Screws: Reinsert the screws and tighten them. The adhesive will help keep them secure over time.

This simple step can save you from wiggly knobs for much longer.
