    Leak Detection & Repair in Leesburg, VA

Fast, accurate, and minimally invasive.

    Electronic Leak Detection

    We use specialized listening devices and thermal imaging to locate leaks behind walls, under concrete slabs, and beneath floors. This lets us find the exact source of a leak with minimal disruption to your home — no guesswork, no unnecessary holes in your drywall. Whether it's a slab leak, a pinhole leak in copper piping common in older Loudoun County homes, or a concealed fixture leak, we'll find it fast.

    Slab Leak Repair

    Slab leaks — leaks under your home's concrete foundation — can cause cracks, damp floors, and high water bills. We locate the leak with precision, then explain your repair options clearly: a targeted spot repair, a full reroute of the affected line, or pipe re-lining where appropriate. We handle permits and inspections so the job is done right.

    Pinhole & Copper Pipe Leaks

    Many older Loudoun County homes with copper plumbing develop pinhole leaks from corrosion. We repair the immediate leak and help you understand whether a targeted repair or a partial/full repipe makes the most sense for your home's age and condition — no pressure, just honest guidance.
