Finding hidden water leaks in Colorado Springs homes

A leak you cannot see still costs water every hour. We prove it exists at the meter, then narrow it down with listening gear and thermal imaging so the one opening we make lands in the right place.

  • Meter test first

Quick answer

Leak detection in Colorado Springs starts at the water meter: with every fixture off, a moving leak indicator means water is escaping somewhere, wet spots or not. Closing the main then splits the house from the yard line, and listening equipment and thermal imaging narrow it to a spot before any wall or floor is opened.

Locating the leak before anyone cuts drywall

Opening a wall where a stain appears often misses, because water runs along studs, joists and pipe insulation before it drips. We narrow the search in stages: is water leaving the system at all, is it inside the house or out in the yard, which branch is losing it, and then which few inches of that branch. Each stage rules out most of the house.

Once the spot is marked, the fix depends on where it is. A line inside a wall is usually a short splice, a line under concrete means choosing between opening the slab or rerouting, and a leak between the meter and the foundation is a yard line repair. Silent toilet leaks get checked first, because they are the cheapest to fix.

Cost

What leak locating costs, apart from the repair

Most cost guides price detection separately from the fix, and the figures below come mainly from slab and pipe leak work. They are third-party numbers, not our prices.

Slab leak detectionThis process costs from $100 to $400, depending on how invasive the detection needs to beSource: Fixr
Pinpointing a slab leakmost homeowners pay between $150 and $400 (about $280 to pinpoint a slab leak)Source: HomeAdvisor
Pipe leak repair plus diagnosis$150 to $350, plus about $100 to diagnose the leak locationSource: HomeAdvisor

What moves the price

  • Whether the meter test shows a leak at all
  • Inside the house or on the yard line
  • Hot side or cold side
  • Tile, carpet or wood over the suspect area
  • How many branches need isolating
  • Sprinklers, softener and RO units on the system

Ranges are published market figures for planning, not a quote. We price your job after we see it.

High water bill with no visible leak

A bill that jumps with no change in how the house uses water usually comes from one of four places: a toilet flapper seeping into the bowl, an irrigation zone valve that never fully closes, a water softener or reverse osmosis unit stuck in a drain cycle, or a pipe leaking out of sight. We check the cheap suspects with dye tablets and a look at the softener and sprinkler valves before any locating gear comes out. Plenty of high-bill calls end with a new flapper and nothing more.

Acoustic and thermal leak locating

Pressurized water escaping through a pinhole makes a hiss that carries along the pipe and through concrete. Ground microphones and contact sensors pick it up, and we follow the sound to its loudest point. Thermal imaging helps on hot lines, which show as a warm streak across a floor or up a wall. Neither tool is magic: a slow cold-water drip under thick carpet pad can be nearly silent, so we combine readings, isolate branches with valves, and mark only what the evidence supports.

Water meter leak indicator used to confirm a hidden leak

Meter test before opening any wall

This is the step we never skip. With every fixture, ice maker and sprinkler controller off, we watch the meter's leak indicator, then close the main shut-off and watch again. If the meter keeps moving with the main closed, the leak is on the service line outside the house. If it stops, the leak is inside. A main valve that will not close fully shows up here too, and it needs replacing before any repair can be done safely.

Local conditions

Leaks between the meter and the house are the owner's to fix

Under Colorado Springs city code, the utility handles the water service line in the public right-of-way, but the property owner is solely responsible for repairing it from the right-of-way or easement line to the building. The curb stop is jointly owned, though only the utility may operate it. Once you find a service line leak, the code gives you 24 hours to report it, then 72 hours to repair a line over 1 inch or 45 days for 1 inch and smaller. A fast, accurate locate keeps those deadlines manageable.
