Leak Detection and Repair in Franklin, NH
You shut everything off and the meter still moves. That's a leak — and in Franklin's basement housing, it could be under the slab, in the crawl space, or in the service line between the meter and your foundation. New Hampshire winters are severe — ground freezes deep, service line failures occur throughout the December through March window. Leak Detection Pros finds it fast, licensed and insured, 24-hour response anywhere in Central New Hampshire.
Signs You Have a Hidden Water Leak in Franklin, NH
New Hampshire winters are severe — ground freezes deep, service line failures occur throughout the December through March window. That seasonal stress creates specific leak patterns in Franklin homes. Here's what those leaks look like before they surface.
Our acoustic and thermal detection equipment finds leaks inside walls, under slabs, and underground — without opening anything first.

We specialize in leaks only — not general plumbing, not HVAC. Every service below uses specialist detection equipment before anything is opened on your property.
Slab Leak Detection — Franklin
New Hampshire winters are severe — ground freezes deep, service line failures occur throughout the December through March window. That seasonal stress is one of the leading causes of slab pipe failures in Franklin. Lines that run through concrete foundations absorb that thermal fatigue year after year until a pinhole develops. We use pressure testing to confirm the leak in under an hour, then acoustic equipment to pinpoint the location before any concrete is disturbed.
Q: How do I know if I have a slab leak in my Franklin home?
A: A warm or soft spot on the floor is the most obvious sign. But many Franklin homeowners first notice a slab leak on their Merrimack Water District bill — a spike of $150 or more with no change in usage. We do a pressure test first, acoustic location second, and give you the exact repair cost before we pick up a tool.
Underground Leak Detection — Franklin
New Hampshire winters are severe — ground freezes deep, service line failures occur throughout the December through March window. Those freeze events are a leading cause of underground supply line failures in Franklin — joint cracks that happen below the frost line and drain away silently through glacial till and granite soil. The meter runs, the bill climbs, and nothing indoors is wet. Pressure isolation and acoustic detection locate the source without a yard-wide excavation.
Q: My Merrimack Water District meter is running but nothing inside is wet — where is the leak?
A: Call immediately. In Franklin, a running meter with no indoor wetness almost always means a buried service line failure — especially after a freeze event. Every day the meter runs is money lost. Acoustic detection and pressure isolation locate the exact failure point, often in the same visit.
Water Main & Service Line Repair — Franklin
After a hard freeze in Central New Hampshire, main line failures spike across Franklin. The ground heaves, the pipe joint cracks, and the meter runs continuously with nothing wet indoors. As the homeowner, you own the service line from the Merrimack Water District meter to your foundation — that means the repair is yours. We handle it from detection through repair, one invoice.
Q: Who owns the water line between the Merrimack Water District meter and my Franklin home?
A: You do. Merrimack Water District owns the meter, but the service line from the meter to your foundation is the homeowner's responsibility in New Hampshire. A failure on that line is your repair — and every gallon lost counts against your bill until the repair is completed. We locate the failure and fix it in one visit.
Irrigation Leak Detection — Franklin
Franklin's glacial till and granite conditions are particularly hard on underground irrigation line joints — the soil moves with moisture levels, flexing fittings until they crack. Most irrigation leaks in Central New Hampshire have no surface sign at all. We isolate each zone with pressure testing, locate the failure with acoustic equipment, and repair with minimal excavation.
Q: How do you find an underground irrigation leak in Franklin?
A: Zone-by-zone pressure isolation and acoustic detection. In Franklin's glacial till and granite conditions, irrigation water drains away immediately — no puddle, no obvious wet ground. We test each zone separately, identify which section is losing pressure, then use acoustic equipment to pinpoint the failure before we start digging.
Bathroom, Kitchen & Ceiling Leak Detection — Franklin
Franklin homeowners often make the mistake of opening the wall where the stain is — which is almost never where the leak is. Water moves through insulation, framing, and drywall before it shows. Thermal imaging maps the moisture path from the visible stain back to the actual failure point. Call before you start cutting — you may be opening the wrong location entirely.
Q: I have a water stain or wet area near my bathroom — what's causing it in Franklin?
A: In Franklin's basement construction, bathroom moisture most commonly traces to a supply line fitting failure, a cracked drain connection, or a failed shower pan. Thermal imaging locates the source before we open anything. Call before you tear out tile or drywall — the visible stain is almost never at the actual leak location.
Gas Leak Detection — Franklin
Gas leak detection in Franklin covers natural gas at the supply line, flexible connection, meter fitting, and appliance level. We use calibrated gas detection equipment to locate failures that visual inspection can't find. The protocol is always the same: if you smell gas, leave now, call 911 from outside first, then call us after the utility has cleared the address.
Q: What should I do if I suspect a gas leak in my Franklin home?
A: Leave immediately without touching any switches or appliances. Call 911 from outside your property. Once the gas utility has shut off supply and cleared the address, call Leak Detection Pros to locate the exact failure point — at the line, fitting, or appliance connection — before service is restored to your Franklin home.
Commercial Leak Detection — Franklin
Central New Hampshire's commercial real estate — retail, multifamily, office — faces ongoing leak risk from pre-1950 to 1970s galvanized and copper infrastructure in older buildings and glacial till and granite soil movement in newer ones. We work with property managers in Franklin to schedule inspections around tenants, test all lines systematically, and provide the written report your insurer or management company needs.
Q: Do you handle commercial leak detection in Franklin, NH?
A: Yes. We serve apartment buildings, retail centers, and HOAs across Franklin and Merrimack. Commercial inspections include full property surveys, pressurized line testing, and written reports for management or insurance. We schedule around your tenants to minimize disruption to residents and operations.

How We Find Leaks Without Tearing Up Your Franklin Property
Four methods. We choose the right one based on the leak type, location, and Franklin's specific soil and construction conditions — not a one-size-fits-all process.
Acoustic Leak Detection
Ground microphones amplify the sound of pressurized water escaping through glacial till and granite soil, concrete slab, and wall cavities. We hear the leak before we touch anything on your Franklin property.
Thermal Imaging
Infrared cameras detect temperature differences caused by moisture behind basement walls and under floors. No cutting, no guessing — we see where the water is concentrated before opening anything.
Pressure Testing
We isolate sections of your supply line or irrigation zones and test for pressure drop. This confirms a leak exists and narrows its location before any excavation happens in Franklin's glacial till and granite ground.
Tracer Gas Detection
For deep underground supply lines, we introduce non-toxic tracer gas into the pipe. It escapes at the failure point, rises through glacial till and granite soil, and our detector pinpoints the exact location — accurate to within inches.
Non-invasive detection — we find it before we open anything. Detection fee quoted upfront.

Why Franklin Has Higher Leak Risk Than Most Markets
Merrimack Water District data shows Franklin generates a disproportionate number of high-usage flags compared to similarly-sized markets. These four local conditions explain why — and why early detection matters more here than in most cities.
🌍 Central New Hampshire Soil: Glacial till and granite
New Hampshire's granite bedrock and shallow soils mean hard ground freezes happen quickly when temperatures drop. Manchester and Concord neighborhoods with pre-1950 housing commonly have original galvanized service lines that have been corroding for decades. Short distance from freeze events to pipe failure makes same-day response critical.
🏗 Construction Type: Basement
Franklin is a small community with predominantly basement construction. In this construction type, supply line failures hide without visible surface signs until located with acoustic or thermal equipment.
🔧 Pipe Era: pre-1950 to 1970s galvanized and copper
Homes built in the pre-1950 to 1970s galvanized and copper period — common throughout Franklin — have supply lines at or approaching end of designed service life. These lines corrode from the inside and fail silently before any surface sign appears at the wall or ceiling.
❄ Seasonal Risk in Central New Hampshire
New Hampshire winters are severe — ground freezes deep, service line failures occur throughout the December through March window. Understanding this seasonal pattern is what separates a technician who knows Franklin from one who's never worked in Central New Hampshire before.
