Answers to Common Questions
View All FAQsHow much does plumbing leak repair typically cost for homeowners?
Plumbing leak repair pricing is confirmed after an on‑site diagnosis, and Roy’s currently offers a $189 Leak Detection Special before repair options are quoted. Most costs are driven by where the leak is and how easily a technician can access it without opening large areas. After we locate the issue using non‑invasive tools (thermal imaging, electronic listening, or cameras), we present upfront pricing so you can approve the work before we start. Small fixture leaks are typically straightforward repairs, while hidden leaks in slabs or water lines may require section replacement or a trenchless method to limit disruption. We service homes across the Buffalo area, including Williamsville, and factor local construction styles into estimating. If water is spreading fast, that is an emergency; our team provides 24/7 response.
What most affects repair cost:
- Leak location: fixture, supply line in walls, under‑slab, or main/water line
- Access method: minimal opening vs. non‑invasive pinpointing; trenchless options when applicable
- Scope: simple seal/part swap vs. section replacement or reroute
- Urgency and any needed water‑damage mitigation
If water is near electrical, shut off the main valve and call a licensed pro right away. <br/> Updated: 2026-05-02 <br/> Need help in Williamsville, NY? Call (716) 202-9997 or book online. “Aaron from Roy’s found the source of our leak, diagnosed the problem and then fixed the issue.” — Laura M.

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.

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. <br/>

Yes. A slab leak can be repaired without replacing the entire slab. Most slab leaks come from a damaged water line beneath the concrete, which can be located precisely with non-invasive electronic listening, thermal imaging, and camera tools. After pinpointing the source, technicians repair the affected pipe section or restore service using targeted methods that avoid large-scale demolition; some water line issues also qualify for trenchless repair to minimize disruption. Our team performs slab leak detection and repair across the Buffalo area using state-of-the-art equipment and upfront pricing. If the leak is isolated, repair is the typical path; full replacement is only considered when wider piping is compromised or repeat failures occur. If water is actively surfacing or you hear hissing under floors, shut off the main and call for leak detection right away. <br/> Updated: 2026-05-07 <br/> Need help in Cheektowaga, NY?
