Bi-folding doors are a stylish and practical addition to any home or business, but over time they can develop problems with alignment, rollers, tracks, locks and other components. At Ace Windows & Doors, we provide specialist bi-fold door repairs and servicing throughout London & Surrey, helping restore doors so they operate smoothly, securely and efficiently.
Many bifold door faults can be repaired without replacing the complete door system. Problems such as dropped or misaligned doors, worn rollers, damaged running gear, faulty locks and handles, glazing issues and general wear can often be resolved by repairing, replacing or adjusting the affected components.
Our aim is to identify the underlying fault and provide a practical repair wherever suitable, helping extend the life of your existing bifold doors and avoid unnecessary replacement.
We provide expert fault diagnosis, high-quality replacement parts, and professional servicing, ensuring long-lasting performance and improved functionality.
Doors not sliding smoothly: Often caused by misalignment, track obstructions, or poor-quality hardware.
Locks or bolts not engaging properly: This issue can result from worn-out lock mechanisms, broken bolts, or incorrect alignment.
Double glazed units slipping or moving: Non toe & heel’d glazing can cause doors to slide incorrectly and fail over time.
Broken handles or hinges: Excessive use or low-quality fittings lead to snapping, loosening, or complete failure.
Gaps or draughts around the doors: Damaged or worn-out seals and gaskets allow air and moisture to enter.
Our team quickly identifies the cause of the issue and provides effective repairs and part replacements.
