I have an in-ground sprinkler system that was installed with thermostat wire instead of sprinkler wire (i guess the genius that put it in was trying to save himself some $$). Now the wire has broken and fused. I need to replace all of the wiring for all 6 zones, replace an antiquated timer, and add a rain/freeze sensor. I have 2 estimates, 1 for $1500, and 1 for $955. Can you please help me?
