Water main replacement cost factors

  • Location of the leak: If the water main line leak is located under your driveway or a slab, the cost to replace the water main line will be more expensive. That's because the plumber will probably need to use demolition equipment (like a jackhammer) to reach the leak. Then you'll also need to factor in the cost to restore your driveway, porch or slab. 
  • Length of the line: The longer the section of pipe that needs to be replaced, the more expensive the total cost of the project will be.
  • Local permit fees: If your plumber needs to pull any local permits, the cost to replace your water main line may increase.
  • The contractor you choose: More experienced contractors generally charge more for their services, but they typically do better replacement work, which saves you money down the road.

Signs you have a water main leak

You might need to have your water main line replaced if...

  1. You notice puddles of water in your lawn. If one patch of ground is wet (and the surrounding areas are not) you may have a water main line leak.
  2. Your water bill is more expensive. If you've noticed a sudden spike in your water bill and your water usage hasn't changed, you may have a water main line leak.
  3. You have low water pressure. When your main water line is leaking water, you may notice decreased water pressure in your home (cold water only). If you turn on a cold-water faucet and the water doesn't flow like it normally does, a leaking water main line might be the culprit.
  4. You notice sudden cracks in your home's foundation. When water gets into the cracks of your home's foundation, it causes the cracks to expand and eventually crack the concrete. Foundation cracks are common in older Boise homes because of aging, but if you notice cracks suddenly, they may be due to a leaking water main line.
