Internal Bi-Fold Doors

The rooms that benefit most are the small ones: en-suites and cloakrooms where a swinging door would hit the sanitaryware, box rooms where the door would land on the bed, and built-in wardrobes and airing cupboards where a hinged door blocks the walkway when open. In an awkward hallway a bi-fold can also free up wall space that a standard door renders unusable.

The trade-off is worth knowing before you commit. A bi-fold has a track and pivot at the head, so it is a slightly more mechanical door than a hinged one and the running gear is what determines whether it still works smoothly in five years. The opening also needs to be reasonably square and the head strong enough to carry the track — both things we check when measuring rather than discover on the day.

Prices include supply, the track and pivot set, and installation. We hang and adjust the doors so they close flush and stay that way, which on a folding door is mostly a matter of getting the track dead level.
