Plumbing leak repair pricing varies by the leak’s location, access, and damage; at Roy’s, leak detection is a $189 special, and repair pricing is confirmed after an on‑site inspection. The biggest cost driver is how accessible the failed pipe is and how much material must be replaced.
Our technicians use non-invasive tools, thermal imaging, electronic listening, and drain cameras to pinpoint the issue and select the least disruptive fix. We regularly serve the Buffalo area, including North Tonawanda homes, and plan repairs to reduce wall cuts or digging when possible. After locating the source, we’ll advise whether a targeted repair is smart or if replacing a larger section will prevent repeat leaks.
Expect costs to rise with:
- Hidden or under‑slab lines that require special access methods
- Long pipe runs or widespread corrosion needing more replacement
- Added water‑damage restoration outside of plumbing repair scope
If water is actively leaking, shut off your main valve and schedule a leak check as soon as possible.

Water leak detection in a home uses non-invasive tools to pinpoint hidden leaks without unnecessary digging or damage. Technicians typically confirm a suspected leak by measuring pressure changes and scanning for temperature differences.
They then correlate those readings with sound and visual cues to map the exact location, even under slabs, so repairs stay small and targeted. This limits disruption and guides whether a simple fixture fix, a short pipe section repair, or larger repiping is the right call. We apply these methods across Western New York homes to protect finishes and foundations.
A typical workflow includes:
- Pressure testing to verify a leak and gauge severity.
- Thermal imaging to trace temperature paths that indicate hidden moisture.
- Electronic acoustic listening to locate leak noise behind walls or under floors.
- In-pipe camera inspection and, for water lines, targeted or trenchless repair once found.
If water is actively running or a ceiling is sagging, shut off the main water valve and electricity to the area before anyone enters.

Slab leak detection typically requires an in-home assessment, and repair pricing varies by leak location, access under the slab, and repair method. Roy’s offers a $189 Leak Detection Special for diagnostics, then provides upfront pricing before any repair. We use non-invasive electronic and thermal tools to pinpoint leaks, and can repair via spot fixes or trenchless water line methods to minimize disruption. 24/7 emergency service is available. We serve Buffalo, Orchard Park, and nearby communities.

"Jeff quickly found the source of the leak and repaired it." — Maria C.
To find a water leak inside a wall or ceiling, use non-invasive electronic leak detection and thermal imaging to pinpoint hidden moisture without opening surfaces. Hidden pipe or water-line leaks are the most common sources, and pressure changes often give them away before staining appears. Roy’s uses advanced tools to locate leaks quickly and accurately, then provides repair options that minimize disruption, including trenchless methods for water lines when needed. Our local team handles these hidden leaks throughout Hamburg and nearby Southtowns.
What a pro will typically do:
- Perform electronic listening and pressure tests to isolate the leaking line.
- Scan with infrared thermal imaging to spot temperature changes from moisture.
- Use targeted camera inspections to verify the exact location before any opening. If water is actively flowing, shut off the main water supply and call for emergency service.

You can safely fix small, accessible leaks like a dripping faucet or toilet flapper, but hidden, in‑wall, slab, or pressurized pipe leaks are not a safe DIY job. Most leaks start from worn seals or corroded piping, and the leaks you can’t see often cause the fastest damage. We regularly help Grand Island homeowners avoid unnecessary demolition by pinpointing leaks with non‑invasive tools; for urgent issues, 24/7 emergency response is available.
Use this quick guide to decide:
- DIY-friendly: faucet drip, toilet flapper, or a loose supply line—only after shutting off the fixture valve.
- Call a pro: water stains in walls/ceilings/floors, warm spots on slab, meter moving with all fixtures off, or recurring moisture.
- Treat as emergency: spraying or burst line, sagging ceiling, hissing near electrical, or any sewage.
- First step: close the main shutoff, avoid energized areas, and document with photos.
If you’re unsure, shut off the main water and call a licensed plumber before damage spreads.

Yes, a slab leak can be fixed without replacing the entire slab. Non-invasive tools like electronic listening, thermal imaging, and cameras let us locate the leak so we repair only the failed section of piping. Emergency leak repairs are available 24/7. Our Buffalo-area team performs slab leak detection and repair with minimal disruption.
Common, low-disruption approaches include:
- Targeted pipe repair through a small access point above the pinpointed leak.
- Trenchless water line repair when the leak is in an exterior supply line.
- Camera verification to confirm the source and check for additional cracks.
If water is actively surfacing, shut off the main valve and schedule a professional inspection.

Yes, epoxy putty or self-fusing tape can temporarily stop a small, low-pressure pipe leak, but they are only stopgaps and not a lasting fix. Most leaks come from corrosion, loose joints, or hairline cracks that usually need a proper repair or part replacement to prevent repeats. Patches fail quickly if the line isn’t fully depressurized and bone-dry before you apply them, and they won’t solve hidden or structural leaks. Our team uses non-invasive leak detection, thermal imaging, electronic listening, and camera inspections to pinpoint the source with minimal disruption for Buffalo-area homes, then repairs the pipe or fitting and, when needed, uses trenchless options on buried lines with upfront pricing. If water is spraying or the leak is concealed, treat it as urgent. Turn off the main valve before anything else.
