What our customers say

Claire, Barry

Extremely happy with the door Rob supplied. He gave great advice when choosing and was always on hand to answer any questions we had. Wouldn't go anywhere else!

Chris, Caerphilly

Rob was helpful from the start always there for any questions I had. 
I work with multiple pvc manufacturers as I own and run a property improvement company and Cardiff composites service was professional with a quality product will definitely be using them again.
