Brilliant bi-fold doors from this business. I bought them 15 years ago and they have worked perfectly. Just recently I had a small problem with the lock on one of them. Called ID systems and one of their Engineers came to fix it at no charge. I was local (Norwich) which I know made a big difference in terms of callout. Brilliant customer service - thank you so much ID systems - you really made my day!
