Thank you for coming out to sort the alarm. Can I just say the gentleman that came was very pleasant and professional. He also warned us when the alarm was going to go off which was nice as I have small children. I just wanted to thank you all for the very efficient service I received from my first telephone call yesterday morning to the engineer's visit today and the emailed report and invoice. I look forward to doing further business with you in future years. Thank you Calder Security for a fabulous service yesterday at my dance school.

Nigel and Debra knew they wanted an MLA registered locksmith to upgrade their locks and found us via their website. Gordon turned to us to service a business fire alarm after a bad experience with a large national company. Following this experience he has continued to use us for his home security needs.
