Frequently asked questions

Should plumbers charge a trip fee on the invoice?

Many plumbers do, especially for diagnostic visits. List it as its own line and state whether it is waived when the customer approves the repair.

How do I price a plumbing bid for new construction?

New construction bids are usually split into rough-in, top-out and finish (trim) phases, with fixtures either supplied by the builder or priced as allowances.

What is included in a construction bid?

The project details, a detailed scope of work, pricing, exclusions, schedule, payment terms, how long the bid is valid and a place for acceptance.

How do I make my bid stand out?

Be specific about scope and exclusions, respond quickly, and make it easy to accept. A bid the owner can approve online often gets an answer faster.
