American Leak Detection of Western Washington is the recognized world leader in non-invasive location of concealed leaks, backed by over 40 years of experience serving homes, businesses, and municipal properties. We operate under one guiding principle: “Leak Detection Without Destruction™.” That means we find the leak, mark it precisely, and hand that information to a repair plumber without tearing through your slab on a guess. Our “Know Before You Go” pricing approach means you understand the cost before we begin, and our technicians arrive on time, finish within the agreed timeframe, and leave your property clean.

A slab leak located before excavation begins may save thousands of dollars. Call us at (425) 276-6850 to schedule a detection visit in Tacoma or throughout Pierce County.

Signs Your Tacoma Property May Have a Slab Leak

The clearest early indicator is a water meter that keeps moving when no water is in use, or a pump that runs continuously. Both signal a loss somewhere in your potable water plumbing (i.e. drinking water plumbing) that supplies your home or building. That loss may be in the service line running from the meter or pump to the house, though leaks are more often hidden beneath the structure itself, inside the hot and cold water lines embedded in or below the concrete slab.

Other signs worth taking seriously:

• Unexplained water bill increases with no change in household usage
• Warm or hot spots on flooring that point to a leaking hot water line below
• Reduced water pressure throughout the building
• The sound of running water when every fixture and appliance is off

Left unaddressed, a slab leak can saturate the soil beneath your foundation. That moisture can erode support over time and may contribute to foundation settlement and cracking. The water bill is often the least expensive part of the problem when detection is delayed.

Our Three-Step Slab Leak Detection Process

We don’t dig until we know exactly where to dig. Our process follows a defined sequence: tracking the plumbing lines, pressure testing the lines to determine whether there is a leak in the system, and determining the location of the water loss and marking the location for the repair plumber.

Each step builds on the last. Tracking maps where the lines run. Pressure testing confirms a leak is present and isolates which line is losing water. Pinpointing and marking tells the repair crew precisely where to open the slab. That sequence is the alternative to hit and miss search or replacement strategies that drive up labor costs, or the search and destroy method that can leave a slab in pieces with a leak still unconfirmed. Accurate detection before any repair work begins can reduce total project cost.

Tacoma Conditions That Put Slabs at Risk

Pierce County’s Pacific Northwest climate keeps soil moisture elevated for extended periods. That sustained saturation can accelerate corrosion in older metal supply lines, and aging galvanized, lead, and polybutylene pipe materials remain in service throughout the area. Ground movement from clay-heavy, glacially deposited soils adds mechanical stress to those same lines across years of seasonal wet and dry cycles.

Slab foundations in the Tacoma area appear across garages, home additions, accessory dwelling units, and some primary home foundations. Any structure on a concrete slab with supply lines running beneath it can be a candidate for this kind of leak, regardless of the building’s age or size.
