Frequently Asked Questions

What are signs of an underground water line leak?

Common signs include reduced water pressure, unexplained wet spots in the yard, foundation moisture, or an unusually high water bill.

Can you repair just a section of the water line?

Yes. If the rest of the line is in good condition, we can replace only the damaged section. If piping is old or corroded throughout, full replacement may be recommended.

Do you offer trenchless underground water line repair?

Yes. In many cases, we can use trenchless methods like boring or pipe bursting to repair or replace lines without extensive excavation.
