Question: how much does it cost to rewire a sprinkler system?
Answer: Replacing a sprinkler system timer will cost $40 to $450, plus labor. Your pro may only need to reprogram or rewire this component instead of replacing it, at an average rate of $50 to $100 per hour. Putting in new wiring for the sprinkler system ranges from $0.50 to $1.50 per foot, in addition to labor charges.
