Plumbing prices in two dialects: time and job. Published national guides put standard work at $75 to $150 per hour plus a $50 to $150 trip fee, emergency at 1.5 to 3 times that. By the job, the anchors are steadier: single drain snaking $100 to $275, main line $200 to $500, hydro jetting $600 to $1,400, camera inspection $125 to $500, leak detection $150 to $600, tank water heater replacement $1,200 to $3,500 installed.
San Gabriel quotes should name the era junction they cross. Old to new transitions, galvanized meeting copper behind a remodel wall, are where scopes hide their contingencies. The written estimate that prices the junction honestly, and states what opening the wall may add, is the one that can be held against a second bid.
What moves a specific quote is mostly access and evidence: a line in an open basement versus inside a finished ceiling, a soft clog versus roots on the cable, a tank swap in kind versus a tankless conversion with new venting. Honest quotes name those factors instead of absorbing them into a mystery total.
The comparison habit that protects you: get the diagnosis in writing, with the part or the footage that supports it, before approving the repair. A price without a named cause is a price you cannot compare, and in plumbing the second opinion is only useful when both are pricing the same failure.
