What Our Customers Are Saying About FastFold Bi Folding Doors
Thank you so much for our amazing new folding doors, they are just perfect and really open up our kitchen dining area. I can not believe the total transformation it has made to our light and the space. A special thank you to the fitting team who took great care in their work and made sure they tidied up after themselves. I am proud as punch of my new folding doors.
Mrs Wright

Brilliant service from start to finish, came today bang on time to fit the 3 fold door in my garden cabin, installers were very professional from the time they arrived. I would highly recommend FastFold UK for its price, communication and professionalism. The cabin has been transformed and looks amazing.
Many Thanks

Just had a set of three bifold doors and a single door fitted. Service and product were exceptional. Dealt with Alan by email for a number of months leading up to the purchase who was extremely helpful and patient in discussing what I required, even sending cill samples so I could make sure the frame fitted correctly. Manufacture and supply only took 6 weeks once I ordered, and the two fitters who turned up were friendly, and professional and had it all fitted in two and a half hours. Cannot recommend highly enough for the service and price which I might add was the cheapest I could find but certainly didn’t mean less quality! Very happy customer, thanks!!
