Main Water Line Repair & Replacement in Annandale: Frequently Asked Questions

How do I know if my main water line is actually failing?

Trenchless or trench — how do you decide?

Based on surface conditions, line material, length, and homeowner priorities. Both options presented when viable.

Will my homeowner's insurance pay for this?

Usually not for wear-and-tear. Service line endorsements may cover. Full documentation provided.

Does Gaa Plumbing pull the permits?

Yes, included in the scope. Handled before excavation.

How long is the warranty on main line work?

1-year on trench repairs. 5-year on new line installations (10-year material warranty on HDPE).
