Customer Testimonials

Last Monday we were locked out of the office (due to a power failure which meant the shutters would not open). Alan from Castle answered the phone within 3 rings and was out on site with us in under half an hour. 15 minutes later he had us in the office and provided us with a brand new padlock. Great job Alan! Thank you.

Very good expert service!
