The complaint
“The GC's plumber no-showed for three weeks and froze the whole addition.”

How we beat the big chains: GCs who rent their plumber run 20%+ higher on wet-space additions. No franchise fees, no commissioned salesmen, no rented subcontractors — that's typically 15–30% under national-brand quotes for the same or better spec. Bring us any written quote and we'll match the scope line by line.
