Preventative Leak Detection Inspections in Redwood City, CA
Beyond emergency services, FBL Plumbing also offers preventative leak detection inspections.

Pool and Spa Leak Detection in Redwood City
Summer heat and wind can evaporate a lot of pool water, so it can be hard to tell normal loss from a leak. A bucket test compares evaporation to actual water loss. We then pressure test plumbing lines and use dye testing around lights, skimmers and fittings. Finding the leak protects the pool shell and the soil around it.
Water Leak Detection in Walls & Ceilings in Redwood City, CA
Water leaks behind walls or in ceilings can go unnoticed for long periods, leading to extensive drywall damage, wood rot and mold. We use non-invasive methods like moisture meters, thermal cameras and borescopes to accurately pinpoint the source of these leaks. This approach minimizes the need for destructive investigation, saving you time and money on repairs to your home's interior.
Water Line Leak Detection in Redwood City, CA

Our goal is to accurately locate the source of the leak, minimizing the need for extensive repairs to your Redwood City home.

Frequently Asked Questions About Leak Detection in Redwood City
Leak detection in Redwood City typically costs $150 to $450 for a typical home, depending on the size of the system and the number of areas tested. Pool leak detection runs about $250 to $500. We tell you the price before we start.
Homes on hard water see scale on fixtures and water heaters, while very soft water can be mildly corrosive to older copper pipe. Hard or aggressive water can cause pinhole corrosion in copper pipes over time. Slab foundations on shifting soils also put stress on pipes underneath the house, and high water pressure in some areas adds more stress.
Turn off all water in the house and watch the meter. If the leak indicator or dial moves, water is escaping somewhere. A sudden jump in your water bill is another strong sign.
Most standard leak detection services can be completed within 1 to 3 hours. More complex cases, such as multiple leaks or hard-to-access areas like under a slab, might take longer to accurately pinpoint.
Older galvanized steel pipes are prone to corrosion, and some older polybutylene pipes are known for early failure. However, even modern materials like copper or PEX can leak due to improper installation, high water pressure or foundation movement.
You can check your meter, test toilets with food coloring in the tank and look for damp spots. Finding leaks under slabs or inside walls requires specialized equipment. That is where professional detection saves time and money.
Many homeowner's insurance policies cover the cost of repairing sudden and accidental leaks, and sometimes the cost of leak detection itself, especially if it leads to a covered repair. It's best to check your specific policy or contact your insurance provider for details.
Yes. Repairs we complete after detection carry a written workmanship warranty. Replacement parts include manufacturer warranties.
