Your options

Choosing the right repair

We look at the cause, the condition of your plumbing, and what will work best for your property.

01

Visible source or hidden path

Water can travel along framing, pipe, and flooring before it becomes visible. The wet spot is not always directly below the failed plumbing.

02

Supply, drain, fixture, or non-plumbing

Meter tests, usage patterns, temperature, fixture testing, and timing help separate pressurized leaks from drains, irrigation, roofs, and HVAC condensate.

03

Repair access

Testing should narrow the likely source so access can be planned around cabinets, tile, flooring, ceilings, business operations, and restoration.

Around the Valley

Dry desert conditions do not make every leak obvious

Water can soak into soil, masonry, cabinets, and wall cavities. A high bill or moving meter may be the first clue even when no puddle is visible.

Planning the work

What affects the price

  • Visible versus concealed source
  • Testing needed to isolate the system
  • Wall, ceiling, slab, cabinet, or underground access
  • Localized repair, reroute, or broader piping work
  • Dry-out and restoration performed by other trades

Common questions

Before you schedule

Does leak detection require opening walls?

Often the testing can narrow the source before access is opened. Final repair may still require access, but the goal is to avoid exploratory demolition.

Can a high water bill be a leak?

Yes. Toilet valves, irrigation connections, service lines, slab leaks, and other failures can waste water without an obvious puddle.

How can I check for a hidden leak?

Turn off known water uses and observe the meter without operating any fixture. If it still registers flow, confirm irrigation and equipment conditions, then arrange professional isolation testing.
