Hidden Water Leak Detection in Castle Rock, CO
High water bill, a damp wall or the sound of running water with everything off? We find the exact spot of the hidden leak in your Castle Rock home, show you the photos, and explain your repair options before any wall gets cut.
The Basics
What is hidden water leak detection?
Hidden water leak detection is how a technician finds a leak you can’t see: inside a wall, under a floor, above a ceiling or in a pipe you can’t reach. We combine a meter check, a pressure check, acoustic listening, thermal imaging and moisture mapping to mark the leak’s exact location. That means a small, targeted repair instead of opening up half a room.
Signs you may have a hidden leak
- A water bill that climbs while your household stays the same
- Hissing or running water when every fixture is off
- A water meter that keeps moving with everything shut off
- Paint that bubbles, drywall that softens or baseboards that swell
- A musty smell in a basement, closet or crawl space
- A warm patch on a floor, or a lawn spot that stays wet
- Water pressure that drops or changes for no clear reason
One sign is a reason to check. Two or more means the leak is probably real and still running.
⏱ Do This First
Do this first: the 5-minute meter test
1
Turn off every fixture, the dishwasher, the washer and the ice maker.
2
Find your water meter. If it sits in a pit with a metal lid, do not leave the lid open in cold weather. Opening it lets warm air out and can freeze pipes.
3
Look at the low-flow indicator. If it spins while everything is off, water is going somewhere.
4
Wait a while and read the dial again. If the number went up, you very likely have a leak.
Castle Rock Homes
Where hidden leaks start in Castle Rock homes
The median Castle Rock home was built in 2007, and about seven in ten were built in 2000 or later. These homes are newer than most, so the usual trouble is not rusted-out old pipe. It tends to be:
2007
Median build year
7 in 10
Built in 2000 or later
Pressure regulating valve (PRV) problems.
High pressure strains every fixture and connection in the house.
Irrigation lines and zone valves.
Irrigation is over three-quarters of summer water use here, so a leak in a zone line can run for weeks unseen.
Water heater and appliance connections.
Slow drips behind a closet door or under a heater.
Outdoor spigots and the lines feeding them.
These are the first to suffer in a hard freeze.
Pipes near the foundation.
Parts of Douglas County sit on expansive clay that swells and shrinks with moisture, and that movement can stress lines close to the house.
Our Methods
How we find the leak without tearing into your walls
We start with the least invasive tool that can answer the question, then confirm with a second method before anyone cuts.
Meter and pressure check
Tells us whether water is leaking and whether pressure is part of the cause.
Acoustic listening
Sensitive microphones on pipes, valves and floors pick up the sound a pressurized leak makes.
Thermal imaging
Shows temperature differences behind walls and under floors. It does not see water, so we confirm with a second method.
Moisture mapping
Shows how far the damp has spread, which narrows where the leak sits.
Pressure testing
We isolate a section of pipe and see if it holds pressure.
High pressure, the leak cause people miss
Normal water pressure in Castle Rock runs 40 to 80 psi, with 65 as a good target. Above 75 can damage appliances. Most pressure changes come from the pressure regulating valve or backflow device on your own home, not from the main. If your pressure jumped, your faucets bang or your water heater relief valve drips, we check the PRV as part of the visit.
40–80
psi, normal range
65
psi, good target
75+
psi, can damage appliances
Could this be why your water bill is high?
Often, yes. Castle Rock Water bills in tiers. Tier 1 is your indoor use, based on your average winter use from November through February. Tier 3 is everything above your budget, at a higher rate per 1,000 gallons, and use above 40,000 gallons in a month carries a surcharge. A small leak running for weeks can push you into the higher tiers without any change in how you live. Castle Rock has also proposed a 5% water rate increase for 2027, so a leak costs more the longer it runs.

FAQ
Frequently asked questions about hidden water leak detection in Castle Rock
How do I know if I have a hidden water leak?
Start with the meter. Turn off everything that uses water and watch the low-flow indicator. If it keeps moving, water is leaking somewhere. A bill that rises with no change in how you use water, the sound of running water with fixtures off, and damp or warm spots on floors and walls point the same way.
Can you find a leak without cutting into the wall?
Usually yes. We narrow the location with acoustic listening, thermal imaging and moisture mapping, then confirm with a second method. If the wall has to be opened, the opening is small and aimed at the exact spot.
How long does leak detection take?
Most visits take a few hours, depending on the size of the house and how many methods it takes to confirm the location. We tell you what to expect when you book.
Is a hidden leak an emergency?
If water is actively spraying or flooding, close the main valve near your meter and call us. A slow hidden leak is not an emergency, but it keeps damaging the structure and raising your bill, so do not wait weeks.
Can a hidden leak cause mold?
Yes. Damp drywall, insulation and subfloor can grow mold, often within days to weeks. A musty smell with no visible source is a good reason to check for a leak.
Will Castle Rock Water adjust my bill if I had a leak?
You may qualify for a leak adjustment. Check your bill’s eligibility with Castle Rock Water. Keep a written record of the leak and the repair, and ask what documents they want, since we cannot promise a credit.
Does homeowners insurance cover leak detection?
Policies differ. Many cover sudden water damage but not always the cost of finding the leak or repairing the pipe itself. Check your policy or ask your insurer, and keep our report with photos for the claim.
Is the leak my responsibility or the city's?
In general, the utility looks after the main and the meter, and the line from the meter to your house is the homeowner’s. Confirm where your property line of responsibility sits with Castle Rock Water.
Do you offer same-day leak detection in Castle Rock?
Same-day when we have an opening. Call us and we tell you how to limit the damage while you wait.
