Leak Detection in Nashua Services We Run
Every leak is different, so we carry the full kit: thermal imaging, acoustic detection, tracer gas, and pipe inspection cameras. If you searched for Leak Detection in Nashua near me and need someone open now, we run 24/7 emergency calls across Nashua and the surrounding ZIP codes. Here is the full lineup of what we handle.
Residential Leak Detection
Homes in Nashua are a mix of older copper pipe and newer PEX tubing, and both fail differently. We pressure-test the system, scan walls with thermal imaging cameras, and check every fixture so you get one clear answer instead of a list of maybes.

Commercial Leak Detection
Restaurants, offices, and retail along Main Street District and the Nashua Mall Area lose money every hour a leak runs. We work after hours to avoid disrupting business, using ultrasonic leak detectors and moisture meters to isolate the problem fast.
View service
Slab Leak Detection
A slab leak in Nashua usually shows up as a warm spot on the floor or a water bill that jumps $80-$200 in a month. We use acoustic listening devices and thermal imaging to locate the break under the concrete before anyone cuts.
View service
Pool Leak Detection
Losing more than two inches of water a week points to a pool leak, not evaporation. We pressure-test the plumbing lines, dye-test fittings, and check the shell so you are not refilling the pool every few days.
View service
Plumbing Leak Detection
Supply lines, drain lines, and everything between. Our plumbers in Nashua trace plumbing leaks with pipe inspection cameras and pressure testing gauges, then hand you a written scope of the repair before we start.
View service
Water Line Leak Detection
The water line from the street to your meter is a common failure point in older Nashua neighborhoods. We isolate the main, check pressure at the meter, and use acoustic detection to find the break without digging up the whole yard.
View service
Gas Line Leak Detection
If you smell gas, leave the house and call us. We use tracer gas detectors and Sewerin equipment to find gas line leaks at joints, valves, and appliance connections, then make the repair code-correct under NH plumbing code.
View service
Sewer Line Leak Detection
Sewer line leaks show up as soggy patches, sewer smell, or repeated backups. We run a pipe inspection camera through the line to find cracks, root intrusion, and offset joints before they collapse under a driveway.
View serviceRoof Leak Detection
Roof leaks in Nashua often start at flashing and ice dam damage from last winter. We use moisture meters and thermal imaging cameras to trace the water path inside the attic so the repair happens at the source, not the ceiling stain.
View service
Foundation Leak Detection
Foundation leaks leave damp walls, white mineral staining, and musty basements. We check the exterior grade, test interior moisture levels, and locate the entry point so you can fix the drainage instead of repainting every spring.
View serviceIrrigation System Leak Detection
A broken irrigation zone can waste hundreds of gallons a week. We pressure-test each zone, check the valves and heads, and find the break with acoustic detection before the lawn turns into a swamp.
View serviceSprinkler System Leak Detection
Sprinkler leaks show up as low pressure at the heads or a constantly wet patch. We isolate the zone, test the backflow assembly, and repair the line so your system runs at the pressure it was designed for.
View service
Water Heater Leak Detection
A leaking water heater is usually a failed tank, a loose fitting, or a bad T&P valve. We check all three, test the water heater parts, and tell you straight whether it is a repair or a replacement.
View service
Toilet Leak Detection
A running toilet can waste 200 gallons a day. We check the flapper, fill valve, and wax ring, then test the flange with a moisture meter so you know the leak is fixed and not just hidden.
View serviceFaucet Leak Detection
Dripping faucets are usually worn faucet cartridges or failed O-rings. We pull the cartridge, inspect the seat, and replace the worn parts with new seals and plumber's tape so the drip stops for good.
View serviceShower Leak Detection
Shower leaks damage the subfloor and the ceiling below. We check the pan, the drain connection, and the valve body, then use moisture meters to confirm the leak is dry before we close anything up.
View service
Bathtub Leak Detection
Bathtub leaks often come from the overflow gasket or the drain shoe. We test both, check the surrounding tile and subfloor, and repair the leak so water stops running into the framing.
View service
Pipe Leak Detection
Hidden pipe leaks in copper pipe and PEX tubing are our most common call. We use acoustic listening devices and pressure testing gauges to find the break, then repair it with the right material for your system.
View service
Drain Leak Detection
Drain leaks leave stains on ceilings and a sewer smell in the basement. We run a pipe inspection camera through the drain, find the crack or failed joint, and repair it before the damage spreads.
View service
Thermal Imaging Leak Detection
Our FLIR thermal imaging cameras read temperature differences behind walls and under floors, showing exactly where water is moving. It is the fastest way to find a hidden leak without tearing out drywall.
View service
Acoustic Leak Detection
Acoustic listening devices pick up the sound of water escaping a pipe under pressure. We use them on slab leaks, underground water line leaks, and any line where the break is not visible.
View service
Tracer Gas Leak Detection
For hard-to-find leaks, we introduce a safe tracer gas into the line and use a Sewerin detector to find where it escapes. It is the most accurate method for gas line leaks and buried lines.
View servicePressure Testing for Leaks
We isolate sections of your plumbing and pressurize them with pressure testing gauges. If the gauge drops, there is a leak. It is the simplest, most reliable way to confirm a leak exists before we open a wall.

Underground Leak Detection
Underground water line leaks waste water and undermine the yard. We use acoustic detection and tracer gas to find the break, then mark the dig spot so only one hole gets opened.
View serviceHidden Leak Detection
Hidden leaks behind walls and under floors are the ones that cause mold. We use thermal imaging cameras and moisture meters to find them without demolition, then show you the evidence on screen.

How Our Leak Detection Process Works
Call and Describe
Tell us what you see: a wet spot, a high water bill, a gas smell, a running toilet. We ask the right questions on the phone and dispatch the closest tech with the tools for that specific leak.
On-Site Diagnosis
The tech pressure-tests the line, scans with thermal imaging cameras, and uses acoustic listening devices or tracer gas to pinpoint the leak. You watch the readings on screen.
Written Repair Quote
We explain what failed, why, and what it takes to fix it. You get a flat-rate quote before any repair starts, and we answer every question until you are ready to decide.
Repair and Verify
We make the repair with the right material, copper pipe or PEX tubing, then re-pressurize the line and confirm it holds. Before we leave, we show you the gauge reading and clean up the work area.
You call, we ask a few questions, and a licensed tech arrives with the detection gear. We diagnose first, show you the evidence, and only then talk about repair. No guesswork, no surprise charges.
Why choose us
Why Nashua Homeowners Call Us First

Licensed NH Master Plumber
Every job is run under a NH Master Plumber License, with Backflow Prevention Certification and OSHA Safety Certification on the crew. We pull permits when the code requires it and leave the work inspection-ready.
Detection Gear on Every Truck
Our vans carry FLIR thermal imaging cameras, RIDGID pipe inspection cameras, Sewerin tracer gas detectors, and Fluke moisture meters. That means we find the leak on the first visit instead of scheduling a second trip.
24/7 Emergency Response
We answer the phone at 2 a.m. for burst pipes and gas line leaks. Average arrival inside Nashua city limits is 60-90 minutes, and we stock the common repair parts so most emergency calls are fixed the same night.
How much does leak detection cost in Nashua NH?
Most residential leak detection jobs in Nashua run $180-$450 in 2026, depending on whether the leak is at a fixture or hidden behind a wall or under a slab. Whole-home surveys with a written report run $650-$1,200. We give you a flat-rate quote after the diagnosis, before any repair starts.
Who is the best leak detection company in Nashua?

How do I find a hidden water leak in my Nashua home?
Start with the water meter: shut everything off and watch the leak dial. If it moves, you have a hidden leak. We confirm it with pressure testing gauges, then use acoustic listening devices and thermal imaging cameras to pinpoint the exact spot. Most hidden leaks take 45-90 minutes to locate.
What should I know before hiring a leak detection pro in Nashua?
Ask three things: are they a licensed NH plumber, do they carry detection gear on the truck, and do they give a flat-rate quote before repair. We meet all three, plus we are insured and bonded. You should also know your ZIP code matters less than the leak type, since we cover all of Nashua.
