Why is my heavy sliding door suddenly so hard to open, and is it a roller problem?

In 90% of cases, the difficulty is caused by a failed roller unit (bogie) or debris accumulation on the track. Rollers contain bearings that seize up or flatten under the door's weight, especially on heavy Lift & Slide systems. We specialize in replacing these specific, high-capacity roller assemblies to restore effortless operation. This is our most common repair.

Modern sliding doors (PVC, Alu, Wood) are equipped with multi-point locking systems that engage in several places along the frame. They are very secure when functioning correctly. If the rollers fail or the door drops out of alignment, the locks cannot engage fully. Our repair ensures the door is perfectly aligned, allowing the security locks to fully engage, restoring maximum protection.

For most standard residential sliding doors (PVC or Aluminium), the repair, including roller replacement and re-alignment, takes between 2 and 4 hours on-site. We aim to complete the job in a single visit as we stock the most common parts.

The cost varies by material and component. A simple alignment and track cleaning may start around €120 to €200. A full replacement of both primary roller units on a heavy door typically ranges from €350 to €600, depending on the complexity of the mechanism (Lift & Slide being higher). We provide a fixed price quote before any work begins.
