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!

Phillip, Bridgend

A good local company and they were very professional. I gave them rough measurements and a few pics and got a price without any sales pitches or forced selling. I was happy with the price and they arrange for a survey to recheck my sizes. Because of this I have placed a second order with them and would rate them as a competitive company, with great customer service skills .

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.
