Our Core Sliding Door Repair Services by Material

PVC Sliding Door Repair

PVC doors are prone to warping, which causes friction and roller failure. We specialize in the precise re-alignment and adjustment of PVC sashes, replacement of failed bogie wheels and runners, and calibration of the multi-point locking systems common on modern doors.

Aluminium Sliding Door Repair

Aluminium doors often use heavy-duty Lift & Slide mechanisms and are subject to wear on the running gears. We repair and replace large weight-bearing rollers, repair damaged tracks, and address thermal break issues that cause frame condensation and heat loss.

Wooden Sliding Door Repair

Wooden sliding doors require careful joinery. We handle the repair of warped frames, the treatment of wood rot affecting the track path, the replacement of traditional roller hardware, and the application of high-performance seals to stop drafts and moisture ingress. We preserve your door's aesthetic and function.

Frequently Asked Questions

We’ve taken the time to provide detailed answers to common inquiries, ensuring you have the information you need at your fingertips.

ALL FAQs
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.

Do you offer emergency repair services for track or lock failure?

Yes, we understand a stuck open or unsecure door is an emergency. We offer rapid response across Brussels for critical issues like broken locks or tracks that prevent the door from being secured. Call our emergency line for priority service.
