“Thank you to Castell Security for sorting out the security for our live music event last month, they went above and beyond to make sure we had the right service at the venue, the market hall in Caernarfon, at a really competitive price. They took away all the hassle and worry, the staff were professional and helpful. There was almost no trouble, and they dealt with the couple of issues we did have quickly and efficiently.
