Professional Leak Detection & Repair in Westport & Fairfield County
Hidden water leaks are among the most destructive plumbing issues a Westport homeowner can face. A pinhole leak in a copper pipe behind a finished bathroom wall or beneath a concrete basement slab can silently discharge hundreds of gallons of water each week, rotting wood framing, feeding toxic mold, and inflating water utility bills.
Westport Pro Plumbing & Drain utilizes state-of-the-art non-invasive electronic leak detection technology. We eliminate destructive guesswork—no randomly cutting open walls or jackhammering floors to find where water is escaping. Our certified technicians isolate the exact failure point within inches.
Once detected, we provide surgical repair solutions ranging from localized pipe crimping and solder bypasses to complete run reroutes that protect your home's finishes.
- Unexplained spikes in your Aquarion Water Company monthly utility bill
- Water meter leak indicator or dial continuously spinning when all fixtures are off
- Warm or hot spots on tile or hardwood floors (sign of a slab hot water line leak)
- Sound of trickling or hissing water inside walls when no appliances are running
- Musty odors, bubbling paint, warped floorboards, or damp basement foundation walls
- Sudden drop in overall water pressure across the house
How We Diagnose & Execute Leak Detection
Step 1: Whole-House Isolation & Meter Flow Testing
We isolate plumbing zones to verify active leakage rates and determine whether the leak is on the hot, cold, or irrigation supply line.
Step 2: FLIR Infrared Thermal Imaging Scan
High-resolution thermal cameras reveal subtle temperature differentials on walls, ceilings, and floors caused by moisture evaporation and hot water pipes.
Step 3: Ultrasonic Acoustic Frequency Detection
Ground microphones and contact listening discs amplify the acoustic frequency of pressurized water escaping through pipe fissures.
Step 4: Non-Destructive Spot Repair & Verification
We access the exact spot with a minimal opening, perform an insurance-approved repair, and conduct pressure decay testing.

Frequently Asked Questions: Leak Detection
How do you find a leak under a concrete slab without digging?↓
We use a combination of acoustic frequency sensors that hear pressurized water spraying underground, electromagnetic pipe locators, and thermal imaging cameras that detect thermal plumes radiating through the slab.
How can I test for a water leak myself before calling?↓
Turn off all faucets, ice makers, and water-using appliances. Locate your water meter and look at the small red or blue flow indicator triangle or digital dial. If it moves at all over a 15-minute period, water is leaking somewhere in your plumbing system.
Is it better to jackhammer the floor or reroute a slab leak?↓
In almost all cases, rerouting a new PEX line overhead through walls and joists is more cost-effective, less disruptive, and eliminates the risk of future leaks on the old buried pipe run.
Will my homeowners insurance pay for leak detection?↓
Most Connecticut insurance policies cover the cost of locating and accessing a hidden leak and repairing the resulting water damage, even if repairing the individual pipe fitting is excluded. We provide detailed reports for your insurer.
