What our customers say

Excellent (10/10)

Great service and support.

I had got quotes for Windows & Doors from other companies in Diss and they were all about the same. I called Polytrade who were a little cheaper but the guys were so helpful. Really can't fault them, will use again.

Very helpful staff and good quality building supplies at a very competitive price.
