“We operate a retail shop near The Quad and had warm concrete under our inventory shelving that caused tile grout to darken. Having someone jackhammer our showroom during business hours was out of the question. Precision came in with acoustic sensors, listened across the slab without opening the floor, and located the leak precisely where the line entered the restroom. We fixed it after hours with zero store closure.”
Slab Leak Detection in The Quad
The area around The Quad at Whittier shopping center includes homes as well as commercial and mixed-use properties. Wherever a hidden leak is suspected, the goal is the same: find it accurately with as little disruption as possible.

Signs worth investigating
Whether your property is in The Quad or elsewhere in Whittier, slab leaks tend to reveal themselves through indirect clues:
- Water use that keeps rising with no change in habits
- A water meter that moves with every fixture off
- Warm or damp areas on the floor
- Musty odors or moisture at the base of walls
- The sound of running water when nothing is on
Any one of these can have another cause. Several together — or a meter that will not stop moving — are a good reason to call. See 10 warning signs of a slab leak for more detail.
Commercial and mixed-use properties
A suspected leak at a business or mixed-use property brings extra considerations — operating hours, customers or tenants, and larger or more complex plumbing layouts. To help us plan:
- Tell us the type of property and roughly how large it is
- Share any building plans or plumbing drawings you have
- Note where symptoms appear and whether they follow business hours or water use
- Let us know any access restrictions or preferred times for testing
Detection is done from the surface first, which helps keep disruption to a minimum while the leak is located. Learn more about our leak location and diagnostic assessment.

What The Quad Area Clients Say
Feedback from homeowners, commercial occupants, and local property managers near The Quad.
“Our water meter showed constant rotation even after we turned off both house valves on our duplex. Precision isolated the dual branch lines quickly, identified the leak on unit B’s hot water loop under the slab, and gave us photo documentation that our insurance adjuster approved without hesitation. Cannot recommend them enough.”
