A pre-hung internal door is different from a slab door. With a slab door, you’ll typically receive the door ‘slab’ (also called the ‘leaf’) alone. It will have a pre-cut hole for the handle set, but that’s all – handy for replacing interior doors of the same size leaf, when the existing door frame is also in good condition. However, new constructions, exterior remodelling, or when replacing doors with frame damage, pre-hung door sets offer a better solution and come with the frame and hinges already attached, along with the architrave, stop beads, and handles to create an altogether superior result.

From handles to hinges, each part of the door system is supplied as a single, pre-constructed product. This includes the door leaf, hung in its own door frame with locks/latches, as well as stop beads, architraves, hinges, and handles also fitted.

Our pre-hung doors are made with engineered solid timber and veneer from the same tree, resulting in a perfectly matching, technically superior finish and function. The frame does not only match the door in colour but with the same veneer and grain structure, amplifying an exquisite, high-quality feel that endures.

Expertly crafted and ready to install, Deuren's internal pre-hung door sets boast a seamless fit that saves time, reduces on-site labour costs, and minimises margins for error during installation. If you need us to take care of the full process for you, we can do that too – from measuring up to design and installation.

Each component comes from one single source, crafted with precision in our UK factory to help reduce carbon footprints. All our doors adhere to stringent European security standards and are made to measure to meet the exact needs of your home or project. By designing and manufacturing our pre-hung doors for your unique space and specifications, security and performance are optimised even further.

First, the door frames should be screwed together, keeping the frame tight and square while fixing together. Next, fit inserts around the frame, avoiding hinges. Upright architraves come next - these will need measuring then glueing to the outside of the door frame, being careful not to get adhesive on the visible part of the frame. Finish by glueing the head architrave. Then, lift up the frame, checking that freccia meets the frame all the way round. If not, a clamp can be used to better secure the frame. Once the glue has dried, remove the clamps and lift the frame into position.

Note: At this point, you may be wondering whether you should install pre-hung doors before or after flooring. It is always more efficient to have the floors put in first. It’s also advisable to install pre-hung doors after the drywall and painting process is complete.

The next step is to level the head and to insert a packer under the leg if necessary. Put a clamp in each corner of the door to adjust the frame as needed, before beginning on hinge installation. Once hinges are screwed into the door, pre-drill screw holes into the frame and use wind bags to lift the door from the ground (another pair of hands can be helpful at this point). Adjust the hinges to get the gap between the door leaf and frame even at the hinge side (approximately three to four millimetres). The rest of the adjustments are done with a combination of hinge and frame clamp adjustments, while gaps can be fine-tuned with expanding foam and packers.

The final step to know when learning how to install pre-hung doors is fitting the telescopic architraves. This can be done by slotting an offcut into the top of the door frame, then measuring from the floor to the top of the architrave. Offer each telescopic leg up to the frame and mark where the grooved cut-out is. A multi-tool or fine-toothed saw can be used to cut this section out, before slotting it into the groove. Finally, the head architrave can be measured. Once it’s apparent the architraves are all the perfect size, they can be removed and attached properly with a small amount of construction adhesive.
