What does a main water line repair/replacement cost in Connecticut?

  • Low: $5,900
  • Median: $8,950
  • High: $12,000

What factors affect the cost of a main water line repair or replacement?

The price of servicing a water main varies based on four factors: whether the line is being repaired or replaced, the length and depth of piping required, the landscaping challenges of the job and the plumbing contractor you hire to perform the work.

  • Repair vs replace: If repairing or replacing a section of your water main is enough to get the water turned back on, it's going to cost a lot less than a full water main replacement.
  • Length and depth of piping: How deep is the existing water main, and how far does it extend between the home and the street? Both factors play an important role in quote you receive.
  • Landscaping challenges: Trees, walkways, patios, driveways and other obstacles can impact how long a project takes and the solutions required to complete the job.
  • The contractor you hire: Pricing for a main line repair or replacement varies based on a contractor's years in business, skill level, training and other factors.

Our 5-star water main repair and replacement process

  1. We secure your appointment

    When you call Aiello or request service online, you're put in touch with a friendly service representative that works right here in our Connecticut office. They'll greet you with a friendly "Hello, Aiello!" and take down your contact info. From there, we'll match you with the perfect plumbing specialist for the job.

  2. We introduce you to your technician

    We want you to feel comfortable with your plumber, even before they arrive at your door. That's why we text you your plumber's name and picture, along with a brief bio with a few fun facts about their background. You can even follow your plumber's service truck while they're on their way to your home, so you know exactly when they'll arrive.

  3. We prepare for a successful water line repair or installation

    During your in-home diagnostic, we'll look at the location of the water main, the obstacles which may impede access to the piping and go over possible solutions for how to complete the repair or replacement. Each customer receives multiple service options to ensure the needs of their home and budget are met.

  4. We give you a 5-star installation or repair experience

    Most main water line projects can take anywhere from 4 to 12 hours. In that time, a team of licensed plumbers will perform the necessary trench or trenchless work, remove some or all of the existing water line and replace it with brand new piping.

Your satisfaction means the world to us

Our goal is to give every Aiello customer a 5-star experience. That's why we ask if we delivered 5-star service at the end of every job. If not, we'll do everything we can to correct that issue before we leave.
