Signs of a Hidden Leak
Not Sure Where the Water Is Coming From?
Hidden leaks cause long-term damage. If you notice any of these warning signs, early detection can save you money and prevent a much bigger repair.
- Higher-than-usual water billsSame usage, rising bill month after month.
- Reduced water pressureWeak flow at fixtures or sprinklers.
- Mold, mildew or musty odorsOften growing in damp, hidden areas first.
- Ceiling stains or saggingWater collecting above drywall.
- Peeling or bubbling paintMoisture pushing through walls.
- Damaged floors or damp carpetA common slab-leak symptom.
- Running water in the wallsWhen no fixtures are turned on.
- Rusty or discolored pipesCorrosion signals deterioration.
How We Find the Source
Advanced Leak Detection Without Unnecessary Damage.
Guesswork means torn-out drywall and lifted floors. We combine diagnostic methods to locate wet areas rapidly and precisely, so repairs start in the right place.
Visual infrared reports available with thermal inspections
Infrared Thermal Imaging
Follows the thermal signature water leaves behind walls, ceilings, floors and building exteriors, and confirms whether an area has fully dried out after water damage.
Pressure Testing & Acoustic Locating
Pressure tests help isolate which line is losing water, and acoustic equipment helps pinpoint where, so slab and underground leaks are found before any repair.
Moisture Mapping
Moisture sensors, thermo-hygrometers and penetrating and non-penetrating meters measure how far water has migrated through materials.
Camera & Borescope Inspection
Sewer cameras and borescopes show the inside of drain lines and wall cavities: the exact spot and nature of a leak, clog or root intrusion.
- No cutting into walls to find the source
- Estimate before any repair work begins
- Findings explained before any repair

How do I know if I have a hidden leak?
Common warning signs include a water bill that keeps rising while your usage stays the same, reduced water pressure, mold or musty odors, water stains or sagging ceilings, peeling or bubbling paint, damaged flooring or damp carpet, and the sound of running water when nothing is on. If you notice any of these, review the signs of a leak and schedule leak detection before the damage spreads.
Can you locate a leak without opening walls?
In most cases, yes. Infrared thermal imaging, moisture meters and camera inspection let us locate wet areas non-destructively, so there is no need to cut into walls or ceilings, pull up tile or tear up hardwood floors just to find the source. Learn more about infrared leak detection.
What is slab leak detection?
A slab leak is a leak in the water lines that run beneath your home’s concrete foundation. Common causes include pressure and soil movement, pipes expanding and contracting with hot and cold water, friction against the concrete, and corrosion in older homes. Slab leak detection pinpoints the exact location so the repair is targeted. Watch for rising water bills, damp carpet, and mold or musty smells.
Does thermal imaging detect every leak?
Thermal imaging is one of our most powerful tools. It reveals the thermal signature water leaves in walls, ceilings and floors. It works best as part of a complete diagnosis, so we combine it with moisture detection, pressure testing and camera inspection depending on what your property needs. See thermal imaging leak detection.
Do you offer emergency leak detection?
Yes. We are available 24 hours a day, 7 days a week, 365 days a year. Call (619) 374-8554. If you have a burst pipe or major leak, first turn off the water at your main shutoff valve (or at the meter if you don’t have one), avoid touching appliances or anything electrical near the water, and contact your insurance company.
Do you handle commercial properties?
Yes. We provide commercial leak detection for office buildings, restaurants, retail spaces, gas stations, apartments and municipal properties, and we give you an upfront quote before we begin any repair work.
What areas of San Diego do you serve?
We proudly serve all of San Diego County, including Downtown San Diego, La Jolla, Carlsbad, Oceanside, Escondido, Chula Vista, El Cajon, Coronado, Poway and Santee. See all service areas.
What should I do if my water bill suddenly increases?
Start by comparing your current bill with previous months. Then look for leaky faucets and running toilets, which can waste thousands of gallons of water a year. If the cause isn’t obvious, a cracked or hidden pipe may be to blame, and professional high water bill detection can find it.
