CL Jones for all you r building needs. They are situated on the Cibyn Industrial Est in Caernarfon just behind the royal mail sorting office. Huge yard there with plenty of stock items from sand and gravel to you r timber needs. A well stocked counter service indoors with plenty on display. A good manager and his staff and they are very helpful as to getting stuff orderd and phoning you if you r orderd items ave turned up. Good value for money here too. The only negative thing there is parking can be a bit of a problem first thing in the morning as everyone want s their stuff at more or less at the same time.
