Diagnostics & Specialty in Northern Virginia

A plumbing inspection before you buy a home costs a few hundred dollars. Discovering a failing sewer line after you close costs tens of thousands. A second opinion on an $8,000 quote from another plumber might reveal that half the work isn't necessary. Diagnostic plumbing isn't glamorous — nobody brags about their backflow test at a dinner party — but it's the work that saves people the most money and the most stress.

We run sewer scopes for home buyers, pressure-test water lines, inspect gas connections, certify backflow preventers, and perform full plumbing evaluations for homeowners who just want to know where they stand. We also offer something simple but rare: a second opinion service. If another company has quoted you major work and something doesn't feel right, bring us in. We'll run our own diagnostics, show you what we find, and give you an honest assessment. If the other plumber was right, we'll tell you that too.

Our diagnostic work exists to give you information, not to generate a sales pipeline. You'll leave every inspection knowing exactly what your plumbing needs — this year, next year, and five years from now.
