Door Installation Step by Step – DIY or with a Professional?

Replacing a door is important not only from an aesthetic point of view: it also significantly affects our home's thermal insulation, security and comfort. Many people think that with a bit of DIY skill they can take it on at home – but is it really worth it? We show you step by step how a door is installed and explain why it is a better choice to turn to a professional.

Step 1: Removing the old door

At first glance it may seem simple, but the wall, plaster or floor can easily be damaged. Professionals work with protective equipment and experienced movements, so unnecessary damage and extra costs are avoided.

Step 2: Preparing the opening

The key to a precise fit is preparation. A laser level, precise measuring tools, a stable base – without these, installation errors can easily occur and cause problems in the long term.

Step 3: Fitting the frame

If the frame is not perfectly level and plumb, the door may warp, fail to close properly, and may even open or close “by itself”. We often see this fault in DIY installations.

Step 4: Fixing and sealing with PU foam

PU foam does not only fix, it also provides heat and sound insulation. But it is only effective if applied professionally – otherwise the whole structure can be unstable.

Step 5: Handle, lock, accessories

A badly drilled lock or handle is not only annoying but can also be dangerous. An experienced professional knows which hardware suits the given door and works precisely.

Step 6: Aesthetic finishing

After the foam has been trimmed and the skirting and trim boards fitted, many people think that the door installer will also do the painting – but that is a separate trade. As a layperson it is easy to underestimate how many different work processes are needed for a perfect final result

DIY or with a professional?

If you want a long-lasting, perfectly functioning door, choose a professional! An improperly installed interior or entrance door can be hard to close, may squeak, or leave gaps – this is not only an aesthetic problem but can also cause heat and sound insulation issues. A faulty lock can also pose a risk to privacy and security.

DIY experimentation often consumes more time and money than could actually be saved – and because of faults arising from unprofessional installation, even the product warranty may become void.
