Bifold door stiff, off its track, or not folding properly? Bifold door problems are almost always a worn track, roller, or hinge — not a reason for full replacement. We diagnose and repair on the same visit.
What We Fix
Tracks, rollers, hinges, handles and locks — we carry the most common bifold door parts on the van and repair on the same visit across London.
Worn, bent or damaged bottom tracks and rollers are the most common bifold fault. We clean, adjust or replace rollers and tracks to restore smooth operation.
Bifold door hinges go out of alignment over time. We re-align and replace pivot hinges, top guides, and swing hinges to get the door folding correctly again.
Shoot bolts and multipoint locking bars repaired or replaced. If the door won't lock or secure at the bottom, this is usually a worn locking bar or keep.
Bifold handles — both internal and external — replaced. We carry standard-size handles in the van for most uPVC and aluminium bifold configurations.
Frames that have dropped or twisted can usually be adjusted back into alignment. We check all pivot points and adjust the frame without removing the door.
Bottom brush seals and compression seals replaced on bifold doors. Stops draughts, reduces heat loss, and keeps rain out on rear bifolds.

Yes — we repair uPVC, aluminium, and timber bifold doors. The mechanisms differ by material and brand, but we carry parts for the most common bifold configurations across London.
