Look for unexplained high water bills, damp walls or ceilings, musty odors, or low water pressure. These are common signals Northern California facility managers search for when they suspect a commercial water leak.
Non-invasive detection uses acoustic listening devices, infrared cameras, and pressure testing to pinpoint leaks without tearing up floors or walls—ideal for office complexes, warehouses, and municipal buildings.
Yes. Underground water leaks can erode soil and crack slabs, leading to costly structural repairs. Early slab leak detection protects both your foundation and your operating budget.
With modern thermal and acoustic leak detection tools, professionals can often locate leaks within hours and guide prompt repairs, minimizing downtime and water waste.
Absolutely. Many counties have strict water conservation requirements and fines for excessive use. Detecting and repairing leaks quickly keeps your business compliant and reduces utility costs.
Strong sulfur/rotten egg odors, hissing sounds, or unexplained spikes in gas bills all point to a possible natural gas leak requiring immediate professional inspection.
Most experts recommend annual gas leak detection and pressure testing, and always after seismic activity or renovations that could stress gas piping.
A gas pressure test ensures that commercial or municipal gas piping can safely hold pressure without leaks. California building codes often require it after new installations or major repairs.
Technicians use sensitive gas detectors, tracer gases, and line-mapping equipment to locate leaks quickly, protecting employees and the public while avoiding unnecessary excavation.
Immediately call PG&E or your local gas utility’s emergency number, evacuate the area, and then arrange for a licensed commercial gas leak detection contractor to inspect and repair the system.
Persistent sewer odors, slow drains, gurgling toilets, or soggy landscaping can indicate a hidden sewer line leak or break.
A high-resolution sewer camera travels inside pipes to identify cracks, blockages, and root intrusions early, allowing targeted repairs and avoiding expensive sewer overflows.
Smoke testing uses safe, non-toxic smoke to reveal leaks, illegal connections, or cross-contamination in municipal or commercial sewer systems, a key maintenance step for older infrastructure.
Yes. Undetected sewer leaks can contaminate groundwater and violate California water quality regulations, potentially leading to fines and public health hazards.
Experts suggest a full sewer camera inspection every 1–2 years for commercial kitchens, high-use restrooms, and aging municipal lines to prevent major repairs and comply with environmental standards.
Common signs of a hidden water leak include higher-than-usual water bills, damp or warm spots on floors and walls, musty odors, or hearing water running when no fixtures are in use. You can also check your water meter: turn off all faucets and appliances, and if the meter is still moving, you likely have a leak. Catching these signs early can save you from costly water damage and mold.
Professional leak detection in Northern California typically ranges depending on the complexity and location of the leak. For example, detecting a slab or underground leak may be on the higher end. The good news is that accurate leak detection helps prevent expensive structural damage, making it a smart investment for your property..
Homeowners insurance usually covers sudden and accidental water damage—such as a burst pipe—but it doesn’t cover long-term leaks caused by neglect or wear. Some policies may also reimburse the cost of professional leak detection if it’s part of repairing a covered loss. Since every policy is different, we recommend checking with your insurance provider before scheduling service.
Modern leak detection uses non-invasive technology to find leaks without tearing into your home. Our specialists use acoustic listening devices, thermal imaging cameras, moisture meters, and video pipe inspection tools to pinpoint leaks behind walls, under slabs, and underground. This means we can locate the problem quickly and accurately, with minimal disruption to your property.

Simple repairs like tightening a fitting or replacing a short section of pipe may cost $150–$300. Larger jobs, such as replacing sections of underground gas line, can cost $800–$1,500+ depending on location and complexity. In Northern California, prices vary with permits and labor, but plumbers typically provide upfront quotes before repairs begin.
Yes. Even a small leak can allow enough gas to build up to cause a fire, explosion, or health hazard. Natural gas is flammable and displaces oxygen indoors, which can lead to dizziness, illness, or worse. For safety, treat every gas leak, large or small as an emergency and call a professional immediately.
Signs of a sewer leak include strong sewage odors, wet or sunken patches in your yard, or multiple slow and gurgling drains at once. Indoors, you might notice pests, mold, or cracks in your foundation. If you live in an older Northern California home (San Francisco, Sacramento, or San Jose especially), these warning signs often point to a sewer line problem that needs immediate professional attention.

The cost depends on the damage and location. Minor pipe repairs might be a few thousand dollars, while a full sewer line replacement can range high.
