By now you will have a good idea what a doorset is so you will want to know how to install one!

Ideally you should put in a subframe made from 18mm MDF or Ply screwed securely to the brickwork. A top Subframe is not required for single doorsets but is for doubles. In a new build this enables you to make an accurate opening and be able to plaster up to it. Then you will be able to install these door sets at the last minute after all decoration has been completed.

As the diagram shows you should allow 45mm on the width and 30mm on the height (from the finished flooring height). So if the door is 762mm, the opening is 762+45mm =807mm.

With this subframe in place it allows you to fix the veneered frame in place ideally using corrugated staples every 150mm using a high powered staple gun. These will be hidden once the architrave is on. Also on the hinge side of the frame replace the hinge screws with long screw in each of the four hinges. You can also put in longer screws through the striking plate. This method of fixing will leave the frame without any noticeable fixing marks. You can see the types of locks and hinges used by clicking the links by viewing the Ironmongery Page.

We have a couple of videos of the SWD Fitters installing doorsets into the preinstalled subframes. Please view the videos. We also have Pictures of doorsets being installed at different stages.
