Red flag
Promised quote on whole-house re-pipe was never sent; customer reported weeks of silence after the technician's visit.
“Contacted Dulles Plumbing Group back in early October of 2021 for a quote on whole house re-piping. Technician came in, sketched the house for the water lines, main rig/manifold, and discussed various ways they were gonna get it done. Everything seemed fine, they said they were gonna contact me with a quote in about a weeks time... It's now been several weeks since then.”

What really stood out was that they provided multiple options for repair rather than pushing just …”
