There's A Better Way Than Digging Up Your Whole Yard

In most cases trenchless technology lets us replace your water line using only two small access points instead of an open trench across your property. Master Bore handles the directional drilling and the plumbing connections with our own in-house crews, so one team is accountable from the first shovel to the final hookup — and your water is usually back on the same day.

We were told our whole driveway would have to come up. Master Bore replaced the line through two small access points instead. Yard looks untouched.

Low pressure for months and two other plumbers guessed at it. These guys found the failing section, quoted it plainly, and had it done in a day.
