Repair Services
Detection and repair handled by the same licensed team, so nothing gets lost between finding the problem and fixing it.
Slab Leak Detection & Repair
A hot patch underfoot or a meter that creeps with everything shut off points at a pressurized line failing beneath the concrete.
Slab Leak →Foundation Leak Detection & Repair
River-confluence clay and a historically high water table push moisture at El Monte foundations. We locate the source before it spreads.
Foundation Leak →Sewer Line Leak Detection & Repair
Camera inspection pinpoints breaks in the cast iron laterals still serving pre-war blocks around Downtown and Five Points.
Sewer Line Leak →Pinhole Leak Detection & Repair
Sixty to eighty years of hard SGV water pits mid-century copper until it weeps inside walls. We find the pinhole, not just the stain.
Pinhole Leak →Pool Leak Detection & Repair
Losing more than a quarter inch a day? Pressure testing separates plumbing loss from shell loss and evaporation.
Pool Leak →Water Heater Leak Detection & Repair
Scale from 10 to 17 grain water shortens tank life. We diagnose valve, fitting, or tank failure before the pan overflows.
Water Heater Leak →Plumbing Leak Detection & Repair
The general call for water you can hear but not see. Full-system testing narrows it to one line, one fixture, one fix.
Plumbing Leak →Pipe Leak Detection & Repair
Supply or drain, copper or galvanized, exposed or buried. Line-by-line isolation tells us which pipe is losing water.
Pipe Leak →Water Line Leak Detection & Repair
The main between the meter and the house crosses your yard unseen. A soggy strip of lawn is often the only warning.
Water Line Leak →Underground Leak Detection & Repair
Buried lines under yards, driveways, and planters get located electronically first, so digging happens in one spot, not five.
Underground Leak →Copper Pipe Leak Detection & Repair
El Monte's tract-boom copper is deep in its failure years. Spot repair, reroute, or repipe, priced honestly for each case.
Copper Pipe Leak →PVC Pipe Leak Detection & Repair
Glue joints, cracked fittings, and root-crushed sections fail differently than metal. We repair PVC drains and irrigation mains alike.
PVC Pipe Leak →Residential Leak Detection & Repair
Homes from pre-war bungalows to 1990s infill each leak in their own way. One call covers detection through finished repair.
Residential Leak →Commercial Leak Detection & Repair
Shops on Garvey, warehouses near the I-10/I-605 interchange, and multi-unit buildings get after-hours scheduling and documented findings.
Commercial Leak →Toilet Leak Detection & Repair
A silent flapper leak can waste hundreds of gallons a day without a puddle. Dye testing confirms it in minutes.
Toilet Leak →Faucet Leak Detection & Repair
Hard water eats washers, cartridges, and seats faster here than in most of LA County. We fix the drip and what caused it.
Faucet Leak →Sink Leak Detection & Repair
Cabinet floor swelling or a musty smell under the basin points to supply, trap, or seal failure. We trace which one.
Sink Leak →Drain Leak Detection & Repair
Waste lines leak slowly and quietly inside walls and under slabs. Camera and dye testing find the break without demolition.
Drain Leak →Shower Leak Detection & Repair
Stains on the ceiling below a bathroom usually mean valve, arm, or pan. Isolation testing tells us which before tile comes off.
Shower Leak →Shower Pan Leak Detection & Repair
A failed pan liner soaks the subfloor every time you shower. Flood testing confirms it, and we repair to code.
Shower Pan Leak →Bathtub Leak Detection & Repair
Overflow gaskets, drain shoes, and deck seals all fail with age. We test each path before recommending a repair.
Bathtub Leak →Bathroom Leak Detection & Repair
The wettest room in the house has a dozen leak paths. Full bathroom isolation finds the one that is active.
Bathroom Leak →Ceiling Leak Detection & Repair
Water travels along joists before it drips, so the stain rarely sits under the leak. Thermal imaging maps the true path.
Ceiling Leak →Wall Leak Detection & Repair
Bubbling paint or a warm stripe of drywall gets scanned and metered first. We open one clean access point, not a wall.
Wall Leak →Crawl Space Leak Detection & Repair
Some pre-1940 El Monte homes still stand on raised foundations. We inspect and repair the lines running beneath them.
Crawl Space Leak →Whole-House Repipe Service
When pinholes keep coming back, replacing the failing copper or galvanized system once beats patching it forever.
Whole-House Repipe →Pressure Regulator Valve Leak Detection & Repair
A failed PRV lets street pressure hammer every line and fixture in the house. Testing and replacement protect the whole system.
Pressure Regulator Valve Leak →Yard Leak Detection & Repair
Green stripes in a dry lawn, sinkholes, or a running meter with the house shut off all point to a buried yard leak.
Yard Leak →Hose Bib Leak Detection & Repair
An outdoor spigot dripping into a planter or behind stucco wastes water year-round in this climate. Quick to fix, easy to miss.
Hose Bib Leak →Irrigation Leak Detection & Repair
Broken laterals and stuck valves show up as soggy zones and summer bill spikes. We isolate and repair by zone.
Irrigation Leak →Sprinkler System Leak Detection & Repair
Heads, risers, and manifolds crack under sun and foot traffic. Zone-by-zone pressure checks find every loss point.
Sprinkler System Leak →Inground Pool Leak Detection & Repair
Skimmer throats, return lines, and light niches are the usual suspects. We test each before anyone cuts deck concrete.
Inground Pool Leak →Hot Tub & Spa Leak Detection & Repair
Spa plumbing hides under shells and decks where a small leak runs for months. Dye and pressure testing locate it precisely.
Hot Tub & Spa Leak →Garbage Disposal Leak Detection & Repair
Leaks from the sink flange, dishwasher inlet, or a cracked housing each need a different fix. We identify which before replacing anything.
Garbage Disposal Leak →Appliance Leak Detection & Repair
Dishwasher and washing machine supply lines fail behind cabinets and walls. We repair the plumbing side and test the connections.
Appliance Leak →Leaking right now? Skip the reading and get a technician moving.
✆ (626) 898-6169Detection Methods
Slab-on-grade construction across El Monte means most leaks hide under concrete. These are the non-destructive methods we use to mark a leak within inches before anything opens. Ask the dispatcher at (626) 898-6169 which method fits your symptom.
Acoustic Leak Detection
Ground microphones hear pressurized water escaping through concrete and soil, narrowing a hidden leak to inches.
Acoustic Leak Detection →Electronic Leak Detection
Line tracing and correlation equipment maps exactly where pipes run and where the signal says water is leaving them.
Electronic Leak Detection →Thermal Imaging Leak Detection
Infrared cameras reveal the temperature shadow of wet material behind drywall and under flooring without touching either.
Thermal Imaging Leak Detection →Ultrasonic Leak Detection
High-frequency sensors pick up the hiss of small pressurized leaks that ground mics and meters can miss.
Ultrasonic Leak Detection →Tracer Gas (Helium) Leak Detection
For the leaks nothing else finds: a safe helium mix charges the line and a sniffer locates where it escapes.
Tracer Gas →Pinpoint Leak Detection
Multiple methods layered on one job to mark a leak location precisely before any concrete or drywall opens.
Pinpoint Leak Detection →Non-Invasive Leak Detection
Every tool on the truck that finds water without cutting: acoustic, thermal, electronic, and pressure isolation together.
Non-Invasive Leak Detection →Trenchless Leak Detection
Locate and assess buried line failures with camera and locator gear, so repairs can go trenchless where conditions allow.
Trenchless Leak Detection →Detection visits get scheduled the same day in most of El Monte. If a line is actively flooding, say so when you call (626) 898-6169 and dispatch treats it as an emergency.
