Castle Rock Leak Detection Specialists
Protect your Castle Rock property by locating a hidden leak before it causes more damage, disruption, or expense. Subsurface Leak Detection of Colorado provides professional leak detection for plumbing leaks, slab leaks, underground water lines, irrigation systems, sewer problems, and commercial properties. Our advanced, non-invasive testing helps narrow the source, avoid unnecessary excavation or demolition, and move the repair forward with greater confidence.
Check the Castle Rock Meter and Utility Side First
Castle Rock Water explains that meters are commonly located in a basement or crawlspace near the street-facing wall, although some are in outdoor pits. With known water use off, meter flow can show whether water is still moving. The Town can also schedule a meter-technician flow-detection service call through its Meter Services.
The Town maintains service to the property-line connection; the private piping after the Town valve or meter connection is the property owner’s responsibility. Water running in the street should be reported to Castle Rock Water at 720-733-6000. Confirm that the address is inside the Town’s water service area because some nearby or extra-territorial properties use other systems.
Private Leak Detection for Castle Rock Properties

Residential Leak Detection
After known fixtures and irrigation are shut down, continuing meter flow may indicate concealed plumbing, a private service line, a slab-related system, or another customer-side demand. The layout and access determine whether acoustic, pressure, thermal, moisture, tracer-gas, or line-tracing methods are appropriate.

Commercial Leak Detection
HOAs, multifamily communities, offices, retail sites, and other managed properties may involve private mains, shared meters, fire lines, common irrigation, and multiple buildings. A system map and isolation sequence help identify the network responsible before location testing begins.

Plumbing Smoke Testing
Sewer odor, open drain connections, and vent problems require a different test plan from water loss. Controlled smoke can reveal odor pathways and failed seals, while camera inspection can support the evaluation of accessible drains or sewer piping.
Castle Rock Is Not One Uniform Property Type
The Town describes more than 150 neighborhoods and a range from 100-plus-year-old homes near the Town center to new construction. Downtown and Craig & Gould, The Meadows, Founders Village, and Crystal Valley are useful orientation points, but neighborhood name or building age alone does not establish the failed material or location.
We review the actual meter position, shutoffs, irrigation, private service route, branch layout, symptoms, and use history before selecting the diagnostic methods.

Frequently Asked Questions
Can Castle Rock Water check whether water is flowing through my meter?
Yes. Castle Rock Water publishes meter-check guidance and can schedule a meter-technician flow-detection service call. A meter showing flow confirms use but does not identify the exact source.
Which part of the Castle Rock service line is the property owner’s responsibility?
The Town says it maintains the service to the property-line connection. Private piping after the Town valve or meter connection, along with in-building and private sewer lines, is generally the owner’s responsibility.
Can a repaired leak qualify for a Castle Rock bill adjustment?
Possibly. The Town publishes an adjustment program for certain high-use events after repair. It may reduce the rate tier rather than remove all metered use, and proof, timing, and frequency requirements apply.
Is every Castle Rock mailing address served by Castle Rock Water?
No. The Town’s service-area map includes defined Castle Rock Water territory as well as nearby areas served by other systems. Confirm the provider for the exact address before using Town-specific ownership or billing guidance.
