I had Callum do several major intricate jobs in my property - Including dealing with the CBUS system. He has to be commended on his attention to detail, the finished repairs and the cleanup. He guarantees his work and is good for his word. The head of the complex, where my property is located, was so impressed he requested Callum do all the strata area and his personal property. I cannot recommend Callum highly enough for his professionalism, knowledge, advice, availability for urgent requirements and his friendly nature.
