What is the difference between a door frame and a jamb?

A jamb, also referred to as a side or head jamb or a door jamb, are the individual pieces of a door frame. The jambs and mullion form the entirety of the frame itself, making for a secure fit in the doorway.

Is there a difference between the door lining and the door frame?

Yes. Door linings are used to hide the gap between the wall and the door. The door frame, on the other hand, is attached to the door and used to hold the door upright with support from the hinges and the overall frame.

How much does a door frame cost?

Door frames vary in cost depending on the material, finish, and make. Internal door frames typically start at less than £40 for the full kit, ensuring that you can transform the doorway without breaking the bank.

Can a door frame be replaced?

Yes, door frames can be replaced. This can be done if wear and tear have weakened the frame or if you want to give your door a new lease of life. You can buy full kits or opt to buy the various parts of the frame, such as the lining or jambs.

Are door frames a standard size?

Door frames do not come in one specific size. You will need to buy the closest size to the door frame you need and then cut it down to the size of the door. This is easy to do and ensures that you get a perfect fit each and every time.
