Leak detection for Highlands Ranch homes
Hidden leaks waste water and rot framing before anyone sees them. In dry climates a slow leak can evaporate as fast as it drips, so a stain may never appear. The first sign is often a water bill that jumps between seasons that should match.

Local conditions
Leak detection in Highlands Ranch: what's different
The earliest Highlands Ranch neighborhoods are reaching the age where original water lines, valves and drain connections start to leak. Many basements were finished years after construction, so pipes behind drywall along foundation walls are hard to reach.
A plumber confirms the leak at the meter, then uses pressure testing, acoustic listening and thermal imaging to pinpoint it. Centennial Water and Sanitation District provides water and sewer service.

Other Highlands Ranch conditions that affect plumbing
- First-generation homes aging: The earliest neighborhoods are reaching the age where original water lines, valves and drain connections start to leak.
- Basement finishing: Many basements were finished years after construction. Pipes hidden behind drywall along foundation walls are harder to reach when a leak starts.
- Outdoor watering: Centennial Water has watering rules and conservation programs; a leaking irrigation backflow device or valve can waste a lot of water quickly.
- HOA and irrigation season: Most Highlands Ranch neighborhoods have irrigated yards and HOA landscaping rules, so spring sprinkler start-up, backflow testing and fall blowouts are routine plumbing tasks.
