Client reviews

Our customers are happy to recommend us.

Fantastic service, cannot recommend 1st Folding Sliding Doors highly enough. Marcus and his team were exceptional and spent time running us through the options and answering questions we had. The doors were fitted to a really high standard and look amazing. If you need Bifold or Sliding doors don't go anywhere else. From start to finish both presale and after sale service is amazing and they were a pleasure to deal with.


We got several roof lights as well as bifold doors done by 1st Folding Sliding Doors. They have been very responsive all through. They adjusted and accommodated any change of dates to fit the work plans of the main contractor. The quality of the work, the finishing and looks are of a high standard. Anything comparable in the market is much more expensive! We have been using these for a few months now- all very smooth and easy to operate. We highly recommend them. Thanks to Marcus and Team.

Excellent service. Marcus and his team do a great job with fantastic backup. More than happy to recommend them. I've already recommended 1st folding to a number of people.

We had a few problems, mainly due to our builder, but 1st folding got everything sorted. Very professional service Staff polite and friendly. Would definitely use them again.

Paul WriteGreat Service!

Thank you for supplying and installing the windows and doors in my property. They look fantastic; the blinds give me privacy and light when required and I will certainly recommend you to anyone. The job was completed on time and problem free.

FENSA enables companies that install replacement windows and doors to self-certify compliance under these Building Regulations without the need for a separate assessment from Building Control.
