FAQ's

Commercial/Municipal Properties

Water Leaks

How do I know if my commercial property has a hidden water leak?

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.

What is non-invasive water leak detection and why is it important for businesses?

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.

Can underground or slab leaks damage concrete foundations?

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.

How quickly can a professional locate and repair a large commercial water leak?

With modern thermal and acoustic leak detection tools, professionals can often locate leaks within hours and guide prompt repairs, minimizing downtime and water waste.

Does Northern California drought policy make early water leak detection more critical?

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.

Gas Leaks

What are the warning signs of a commercial gas leak?

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.

How often should Northern California businesses schedule gas line inspections?

Most experts recommend annual gas leak detection and pressure testing, and always after seismic activity or renovations that could stress gas piping.

What is a gas line pressure test and when is it required?

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.

How do professionals locate underground commercial gas leaks safely?

Technicians use sensitive gas detectors, tracer gases, and line-mapping equipment to locate leaks quickly, protecting employees and the public while avoiding unnecessary excavation.

Who should I contact first if I suspect a natural gas leak in my building?

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.

Sewer Leaks

What are common signs of a sewer line leak in a commercial facility?

Persistent sewer odors, slow drains, gurgling toilets, or soggy landscaping can indicate a hidden sewer line leak or break.

How does a sewer camera inspection help prevent costly backups?

A high-resolution sewer camera travels inside pipes to identify cracks, blockages, and root intrusions early, allowing targeted repairs and avoiding expensive sewer overflows.

What is sewer smoke testing and when is it recommended?

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.

Can sewer leaks affect local health and environmental compliance?

Yes. Undetected sewer leaks can contaminate groundwater and violate California water quality regulations, potentially leading to fines and public health hazards.

How often should businesses schedule professional sewer line inspections?

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.

Residential Properties

Water Leaks

How do I know if I have a water leak in my home?

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.

How much does leak detection cost?

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..

Will my insurance cover plumbing leaks or leak detection?

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.

How do plumbers detect hidden leaks?

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.

Do you offer emergency or same-day leak service?

Yes. We understand that leaks can’t wait—whether it’s water pooling indoors, a slab leak, or a burst pipe. That’s why we provide 24/7 emergency leak detection and repair throughout Northern California. If you have an urgent leak, call us immediately, and our team will dispatch a technician to your property the same day.

What should I do if I smell gas in my house?

If you smell rotten eggs (sulfur), evacuate immediately—don’t flip switches or light anything. Once outside, call 911 or PG&E’s emergency gas line. After the gas is shut off and the area is safe, call The Leak Authority who is a licensed plumber in Northern California and specializes in gas line repair to fix the problem before restoring service.

How can I tell if I have a gas leak?

Should I call the gas company or a plumber for a gas leak?

Call the gas company first (PG&E in most of Northern California) or dial 911—they’ll shut off the gas and make your home safe. After that, call a licensed residential plumber to handle the gas line repair. The gas company ensures safety, while plumbers perform the actual fix.

How much does gas leak repair cost in Northern California?

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.

Are small gas leaks dangerous?

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.

How do I know if I have a sewer leak in my home?

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.
