What types of aluminium doors do you repair?

How long does a sliding door repair take?

Most repairs take 30–60 minutes. Roller-only replacements are usually done in under 45 minutes; track and roller replacements take around an hour.

How do I know if I need a track replacement or just new rollers?

If your door is stiff or noisy but the track looks straight and clean, rollers are usually the culprit. If the track is visibly bent, corroded, or grooved, a full track replacement gives the best long-term result. Our technician will confirm on arrival.

Yes. We Fix Doors can carry out sliding door repairs without removing your security gate. You do not need to dismantle or move the gate before we arrive.

What are the most common sliding door problems?

The most common sliding door problems are worn or broken rollers, dirty or damaged tracks, misaligned door panels, faulty handles or locks, and damaged seals. Worn rollers cause the door to drag, grind or jam. Bent or corroded tracks prevent smooth sliding. Our technicians diagnose and fix all of these issues, usually in a single same day visit.
