All of our Bi-folding doors are fully assembled and tested in the factory jigs prior to despatch.

They are photographed up to 28 times to ensure they reach you in perfect working condition.

These photographs are then put into every accessory box that is sent out with every door along with full fitting instructions.

Note: The above would not apply if we are fitting for you, as our experienced fitters know exactly what they are doing.

Beaufort Bi-fold Quality Control

We believe that the best way to make sure that every single one of our Bi-fold doors arrives to you in an excellent working condition, is to check them thoroughly before they leave the factory. Each Bi-fold door therefore that leaves the factory is checked by Quality Control; for more details see our Quality Control page.
