What a General Plumber Handles Well

For visible, accessible leaks — a dripping faucet, a leaking supply line under a sink, a toilet that won't stop running — a general plumber has everything needed to diagnose and fix the problem in a single visit. Most routine plumbing leaks fall into this category and don't require specialized detection equipment.

If a situation like this is happening right now, you can request emergency service and we'll get moving.

When a Specialist Makes More Sense

If the leak's source isn't visible — a slab leak, a leak inside a wall cavity, or a leak in an underground yard line — a dedicated leak detection specialist with acoustic, thermal, and moisture-mapping tools is typically better equipped to pinpoint the exact location before anyone starts cutting into concrete or drywall. Many plumbers refer these cases out precisely because locating a hidden leak is a different skill set than repairing one. If you want to go deeper on this, our guide on Repiping vs. Spot Repair: Deciding After a Leak Detection Report covers it well. We also break this down further in Protecting Your Phoenix Vacation Home from Water Damage.

Some Companies Do Both

A number of Phoenix restoration and plumbing companies offer combined leak detection and repair services, which can simplify the process since the same team locates and fixes the issue. If you go this route, ask specifically what detection equipment they use and whether locating the leak is included in the service call or billed separately. For background from an independent source, see the IICRC S500 restoration standard. the Insurance Information Institute's claims overview has useful guidance on this if you want to read further.

Coordinating Detection, Repair, and Restoration

For leaks that have already caused visible water damage, you may end up working with three parties: a leak detection specialist to find it, a plumber to fix the pipe, and a restoration company to dry out and repair the affected structure. Our guide to choosing a water damage company covers how to keep that process organized rather than juggling separate, uncoordinated vendors. You can also review FEMA's National Flood Insurance Program for an outside perspective on this.

Frequently Asked Questions

Some can with basic tools, but a dedicated leak detection specialist with acoustic and thermal equipment is generally better equipped for underground or slab leaks.

Some do, others focus only on locating the leak and hand off the repair to a plumber — ask before booking to understand what's included.

It can add a step, but accurately locating the leak first usually reduces overall repair costs by avoiding unnecessary demolition.

If you can't see or access the leak directly — it's inside a wall, under a slab, or underground — that's a strong signal a specialist's tools will help.

Ask what detection methods they use, whether they also handle repair, and whether the detection fee applies toward any repair work.
