Repairing your home’s main water service line costs $400 to $1,500 on average. Most homeowners spend around $950 for materials and labor to fix the water line. However, that cost varies greatly depending on the location and extent of the damage. If the repair involves digging up concrete or landscaping, costs may go much higher than average.
The home’s main water line typically runs underground from the house to the city’s main water supply line at the property’s edge.
