Repair your sliding door or sliding window yourself: with knowledge and support
A poorly operating sliding door or sliding window rarely needs to be replaced immediately. In most cases, it is wear on parts such as carriages, wheels or locking parts. With the right information and support, you can often repair this yourself.
At Van Doorn Openingstechnieken we help customers with:
✔ clear blogs
✔ practical YouTube explanations
✔ personal support via email or chat
✔ Sliding door (NL), sliding window (BE) and lift-and-slide door
The terminology differs per country:
✔ Netherlands: sliding door, lift-and-slide door
✔ Belgium: sliding window, lift-and-slide window
The technology and parts are the same.
Also read our brand- and system-focused blogs about this, such as:
-
GU sliding door parts

✔ For which brands is self-repair possible?
In practice, self-repair is quite possible with almost all common systems, including:
