Leak Detection in Thornton, CO
A water bill that jumps with no obvious cause, or a damp spot that won't dry out, usually means a hidden leak somewhere between the meter and the fixture, and electronic leak detection finds it without cutting open walls or flooring to search.
Leak Detection In Thornton
Thornton's expansive clay soil movement is a common contributor to hidden leaks here, since ground shift can stress a buried line or a slab-set pipe at a joint that was perfectly fine when the home was built decades ago.
Signs You May Need Leak Detection
A water bill that rises with no change in household water use
A damp or warm spot on a slab floor
The water meter still moving with everything in the house shut off
A musty smell with no visible source of moisture
What Causes This
- A pinhole leak in an aging copper or galvanized line
- A joint stressed by expansive clay soil movement
- A slab leak beneath the concrete foundation
- A leak in the underground line between the meter and the house
How We Diagnose The Issue
We use acoustic listening equipment and, where needed, thermal imaging to pinpoint a leak's location without guesswork, confirming the spot before any cutting or digging starts.
This work follows the International Plumbing Code (IPC), which Colorado has adopted statewide, along with any local Thornton permit requirements that apply.
Fixing It Right
Once located, an accessible leak is repaired directly. A leak under a slab or driveway sometimes calls for rerouting the line through an accessible path instead of breaking through concrete, which we'll lay out as an option before starting.
Stopping It From Recurring
Keeping an eye on your water bill month to month is one of the simplest ways to catch a hidden leak early, since a real jump with no change in household habits is usually the first sign. Knowing your water meter's location and checking it occasionally with everything in the house off can confirm a suspicion before it becomes a bigger problem. For a home with known expansive soil movement nearby, an occasional professional check on exposed and accessible plumbing is a reasonable precaution rather than waiting for a warning sign.
What To Check Before You Call
What to do before we arrive
- Check your water meter with everything in the house off. If it's still moving, a leak is very likely.
- Do not attempt to cut into a wall or floor yourself to search for a suspected leak.
- Note when you first noticed a higher water bill or a damp spot, since timing helps narrow down the cause.
- Shut off the main water valve if you see active water pooling anywhere, even if the source is unclear.
The Cost Of Waiting
A hidden leak left undetected doesn't just waste water and money on the bill, it can cause mold growth, structural damage, or foundation issues depending on where it's located and how long it continues. What might have been a straightforward repair when first suspected can become a significantly larger job once water has had months to spread through wood framing or beneath flooring.
Cost Factors To Know
Every job depends on what we actually find, but these are the real factors that move the price:
Detection method needed
A straightforward leak is faster to locate than one requiring thermal imaging or specialized equipment.
Leak location
An exposed line costs far less to repair than one under a slab or driveway.
Repair vs. reroute
Rerouting around a slab leak sometimes costs less overall than breaking and repairing concrete.
Extent of hidden damage
A leak found late may have caused damage that needs its own separate repair.

Leak Detection FAQ
Acoustic equipment picks up the sound of water escaping under pressure, and thermal imaging can reveal temperature differences from water in an unexpected place. Both let us narrow the location before any cutting starts.
Leak detection covers finding any hidden leak in the home's plumbing. A slab leak specifically refers to a leak under the concrete foundation, which needs its own detection and repair approach.
A rising water bill with no change in usage, a warm or damp spot on the floor, or a water meter that keeps moving with everything off are the clearest signs.
Even a leak too small to notice by sound or sight can waste a significant amount of water over weeks or months, which is usually what first shows up as an unexplained jump in the bill.
