What this site is
WaterMainCall is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands, and work on a service line is normally permitted and often coordinated with the utility — ask to see the permit. We carry out no work, we test no water, we do not set prices, and we never charge homeowners anything. Nothing here is a statement about the water at any address.Checking a credential in Delaware
Delaware licenses are issued by the Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners, which publishes a public search you can use before work begins.

How a water line repair job goes
A service line repair starts with a question of ownership. The utility is responsible up to a point written into its own policy — usually the main, the curb stop or the meter — and the homeowner from there. Finding the leak is one job; establishing which side of that line it is on is what decides who pays, and it is worth settling before the excavator arrives.
What the call asks about water line repair
- Where the water is surfacing, and whether it is between the meter and the house or on the street side.
- Whether the meter is in a pit at the boundary or on the wall of the house.
- Whether the utility has already been out and said whose side it is on.
