I used them to fix a non-working sprinkler system. They charged $178. A month later, I called the back because the system still was not working. They charged $244. They also told me that I would have to pay another $150-$200 for further repair. I called another company, who came out and found all the wires in the control box switched around and covered in cobwebs. Evidently the box was not checked the first two visits. The new company charged $30 to repair and $60 for the service call.
