Water Leak Detection in Walls & Ceilings in Upland, 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.

Fixture and Appliance Leak Detection in Upland, CA
Running toilets, worn faucet cartridges and leaking water heater connections waste more water than most people realize. A silent toilet leak can lose hundreds of gallons a day. We check flappers, fill valves, supply lines, softeners and water heater fittings. These repairs are usually quick and inexpensive.
Hidden Wall and Ceiling Leak Detection in Upland
Leaks inside walls and ceilings often show up as stains, bubbling paint, soft drywall or a musty smell. We use thermal cameras to spot temperature differences caused by water, then confirm with moisture meters. Acoustic tools help when the leak is on a pressurized line. Pinpointing the source lets us cut a small, clean access opening.
Advanced Leak Detection Technology in Upland
FKM Plumbing invests in modern leak detection technology to provide precise and efficient service. Our tools include high-resolution thermal cameras, sensitive acoustic sensors, non-toxic tracer gas and digital moisture meters. This equipment allows us to identify leaks in various materials, from copper and PVC to PEX, with minimal disruption to your property.
Pool and Spa Leak Detection in Upland
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.
Sewer Line Leak Detection in Upland, CA
Sewer line leaks can cause foul odors, slow drains and potential health hazards. Our team uses camera inspections to visually identify breaks, cracks or blockages within your sewer lines. This method allows for precise location of the leak without guesswork, leading to more efficient and targeted repairs. We address sewer leaks in all types of piping materials common in Upland homes, from PVC to cast iron.
PEX and Copper Pipe Leak Detection in Upland, CA
Whether your Upland home has modern PEX plumbing or traditional copper pipes, leaks can occur. We are experienced in detecting leaks in all common piping materials found in Southern California homes. Our tools are designed to work effectively with both metallic and non-metallic pipes, so no matter your plumbing system, we can reliably locate any leak. We handle everything from pinhole leaks to joint failures.

Main Water Line Leak Detection in Upland
The service line between your meter and house can leak underground for months, especially in older galvanized or copper lines. Wet spots in the yard, oddly green grass or a sinking area near the front of the house are clues. We use line tracers to map the pipe and ground microphones to hear the leak. That keeps excavation to a small, targeted hole.

Frequently Asked Questions About Leak Detection in Upland
The cost of leak detection in Upland, CA can range from $250 to $800, depending on the complexity and location of the leak. Factors like slab leaks or hard-to-reach pipe leaks may be at the higher end. We provide a clear estimate after our initial assessment.
Small repairs usually do not, but reroutes, repipes and main line replacements often do. Requirements vary by city and county. We handle any permits needed.
Older homes may have galvanized steel or polybutylene pipes, both known for higher leak rates due to corrosion or material breakdown. Copper pipes can develop pinhole leaks over time, while PVC and PEX are generally more reliable but can still leak at fittings or due to installation errors.
Most residential leak detection appointments take one to three hours. Larger homes, commercial buildings or multiple leaks can take longer. We give you an time estimate when we schedule.
Municipal water across much of Southern California is hard, leaving chalky scale on faucets, showerheads, and inside water heater tanks. 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 strain.
If a gas leak is suspected, right away evacuate the property and call 911 or your gas provider. Once the area is safe, FKM Plumbing can be called to precisely locate the leak and perform the necessary repairs according to strict safety protocols and codes.
While you can check for obvious leaks like dripping faucets, hidden leaks require professional tools and expertise. DIY attempts can often misdiagnose the problem or cause further damage, especially with slab or gas leaks.
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 clear sign.
