I have used other builders' merchants in Cardiff but none compare. All materials priced competitively and they stock everything you need.
Liam Gaughan
Great company, best builders' merchants in Cardiff. Nice staff and a great bunch in the yard.

Phoned up to get some bulk bags delivered as needed asap and other suppliers saying they couldn’t deliver for several working days. Guy on the phone was really friendly and helpful and they turned out far cheaper too so i was glad i wasn’t able to order through the other supplier in the end. Phoned about 4pm and the delivery came at 8am the following day! Delivery guy was just as good too. Will be going to them first in future.
