Perry was introduced to us to help with our telephone system, which seemed to have developed faults with a couple of the phones. As the wiring looked like a bird's nest from previous attempts to fix the situation, he suggested they rewire the system.
There was minimal disruption while they worked, left a lovely neat tidy job and the problems have been solved.
Perry and Dave obviously have a very wide and in-depth knowledge of telephone systems and I would therefore highly recommend them.
