Hi, I live in the Ffestiniog area north Wales, and for ten years I had been looking for a reliable builder. I was recommended Evans building plastics by my daughter.

I've now used Evans for many years. I would recommend them to anybody, and I've recently had new windows and new roof by them.

They have very good workmanship and are very neat and tidy.
