Beautiful Bifolds fitted our lovely roof terrace bifold doors. They were very professional and quick to respond on text and email. We had a slight problem with the locking mechanism on our door due to a factory fault. I phoned Andrew who immediately arranged for his team to repair to door that night. The Engineer came over and fixed the problem within 10 minutes. It’s really reassuring to know that they were more than happy to come back and sort out any glitches even after installation. Would definitely recommend.
