What actually moves the price
Depth & shared mains
Back-to-back townhomes with deep shared mains change shoring, equipment, and time — we’ve dropped 9 ft then 15 ft in a few yards of trench.
Right-of-way / under-street work
Permits, 811, traffic control, and full-lane repaving multiply cost vs the same footage in the yard.
Camera + line location first
Free with drain cleaning; standalone $350–$550. Footage decides spot vs sidewalk vs full-to-main — and trenchless vs dig.
