Mainline Leak Detection is a husband-and-wife-owned company operated by Brian and Angie Kirk, serving homeowners, businesses, property managers, contractors and municipalities throughout South Central Pennsylvania.
We built Mainline around a simple idea: before you tear it apart, dig it up or start replacing things, find out where the problem actually is.
Hidden leaks require more than guesswork. Mainline uses specialized diagnostic technology and proven investigative methods to locate leaks beneath concrete, underground and behind finished surfaces—helping our customers and their repair professionals determine where to focus their efforts while minimizing unnecessary damage and expense.
As a veteran- and woman-owned family business, Mainline brings a personal level of responsibility to every job. When you contact Mainline, you're working with the people who own the company—not a national call center or a rotating network of subcontractors.
Brian handles the technical side of leak detection and investigation, using specialized equipment and experience to identify and pinpoint difficult problems. Angie works alongside him in the business, helping ensure customers receive the responsive, professional service expected from a locally owned company.
Our job isn't to sell you a repair. Our job is to find the problem.
That distinction matters. Because Mainline specializes in detection and investigation rather than performing the repair itself, our focus is on providing accurate findings and useful information that homeowners, plumbers, contractors, property managers and other professionals can use to determine the appropriate next step.
Our mission is to locate hidden leaks and water-related problems as accurately and non-invasively as possible—reducing unnecessary demolition, excavation, disruption and repair costs.
From a hidden leak in a family home to underground piping serving a commercial property, farm or municipal facility, we approach every investigation with the same goal:
Find the problem. Pinpoint the location. Give the customer clear answers.
Mainline Leak Detection serves York, Lancaster, Adams, Dauphin, Cumberland and Chester counties and surrounding areas of South Central Pennsylvania.
