Centennial homes from the 1970s and 1980s have supply lines that have been in service for decades, and aging supply lines develop pinhole leaks at corrosion points that can run slowly inside walls and ceilings for weeks before becoming visible as water stains. A water meter that runs when all fixtures are off, unexplained wet spots on walls or ceilings, and unexplained increases in water bills are all signs of a hidden leak in a Centennial home that should be investigated before the leak causes structural damage or mold growth.

After the leak is located, repair is the next step. Our pipe repair team handles the supply line repair or replacement once the source is confirmed. For leaks in slab foundations, the repair approach depends on the pipe condition and leak location. See all Centennial plumbing services.

• Hidden wall and ceiling leak detection for homes with water stains or wet spots where the source is not visible at the surface.
• Slab leak detection for homes where a supply line under the concrete floor has developed a leak, often indicated by warm spots on the floor, wet floor surfaces, or unexplained water bills.
• Water meter leak check to confirm whether a running water meter with all fixtures off indicates a leak in the supply system.
• Irrigation and exterior line leak detection for homes with underground supply lines to irrigation systems or exterior hose bibs that may be leaking below ground.
• Post-repair leak verification to confirm a repaired line is holding correctly before walls are closed or slabs are patched.

Here are the leak detection calls our Centennial plumbers handle most often.

How Do I Know If My Centennial Home Has a Hidden Leak?

The clearest non-visual signs of a hidden leak in a Centennial home are a water meter that continues to run when every faucet, toilet, and appliance is off, an unexplained increase in water bills that does not correspond to any change in usage, and the sound of running water inside walls when no fixtures are in use. Visual signs that appear later include water stains on walls or ceilings, soft or discolored drywall, peeling paint or wallpaper near plumbing walls, and visible mold growth in areas adjacent to plumbing.

In Centennial homes with copper or galvanized supply lines that are 40 or more years old, pinhole leaks are a known failure mode. Copper in certain soil conditions and galvanized steel as it corrodes internally can both develop small leaks at corrosion points that start slowly and worsen over time. Early leak detection allows for targeted repair before the leak causes significant damage.

What Is a Slab Leak and How Is It Repaired in Centennial?

A slab leak occurs when a supply or drain line running under the concrete slab foundation of a home develops a leak. In Centennial, slab leaks most commonly occur in copper supply lines that have corroded through from the outside due to aggressive soil chemistry, or at joints and fittings that have shifted over time. Symptoms include warm spots on floors for hot water line leaks, wet floor surfaces, reduced water pressure, and the sound of water running when all fixtures are off.

Repair approaches for slab leaks include breaking through the slab at the leak point for a spot repair, rerouting the affected line through the wall or ceiling to bypass the slab section entirely, or whole-home repiping where the slab-routed lines are abandoned and new lines are run through the walls.
