It depends on the municipality, but it can range from a couple hundred dollars to a few thousand dollars. The main water line repairs will usually be one of the more expensive jobs a homeowner has to undertake. The cost can vary depending on several factors, such as the distance between the shut-off valve and the source of the break, how accessible the broken pipe is, and whether or not any underground utilities need to be moved. If there is extensive damage to your property or if you have a flooded basement, those costs will also add onto the final bill.
