I have used them for two different jobs in the past year. In both cases they were EASY to work with, and I was Confident in the workmanship. One project took a lot of communication and was a challenge, getting power to an exterior stucco wall to mount a flat panel TV. The other was a "standard", leaking exterior manifold. The simple job got done fast with one call, and for the complex job we were provided with options and multiple resources to get it done right.
