Wonderful service from start to finish. I came across Prime Aluminium online, after receiving a few quotes from others I found these to be the best price I could find. Delivered within the time scale promised and really pleased with the quality of the doors. Send them a picture of your door after it’s been fitted and you will be entered in to a draw for a voucher. Fingers crossed. Thank you.

Very happy with our doors, we got a few quotes from some other companies which was in excess of £10,000 for 4 bi-folds – Prime Aluminium saved us over £3000. Anyone thinking about fitting yourself just make sure there is 2 of you as the panels are about 50kg each. Will recommend in the future to anyone looking for new bifold doors.
