Water Line Services

Water Line Leak Detection

Using advanced acoustical leak detection equipment, we locate hidden leaks under slabs, in yards, or within walls—without unnecessary digging.

Water Line Repair

We repair broken or cracked water lines caused by root intrusion, corrosion, shifting soil, or age. Our goal is to preserve as much of your property as possible.

Full Water Line Replacement

If your line is beyond repair or made from outdated material (like galvanized steel), we offer full replacements using modern, long-lasting pipe—installed with minimal disruption using directional boring and trenchless methods where possible.

Main Shut-Off Valve Replacement

A working shut-off valve is critical during emergencies. We replace or upgrade old, corroded, or stuck main shut-off valves for quick, dependable control.

Backflow Prevention Installation & Repair

Protect your home’s water supply from contamination. We install and service backflow preventers to meet local codes and keep your drinking water safe.

Boring & Underground Piping Services

For full replacements or major reroutes, we use directional boring to minimize surface damage and get the job done efficiently—even under driveways, sidewalks, or landscaping.

Pressure Testing & Line Inspections

We test your water system for pressure loss or irregularities and inspect for leaks, blockages, or worn components.
