These six details tell you what you're agreeing to. Under each one is how many of the 15 plumbers in this report told us. ### Total price and what it includes Ask whether the quote includes permits, materials, cleanup and any equipment. A low number that leaves out part of the job isn't a low number. Disclosed by **0 of 15** plumbers below ### Deposit at signing Know the amount before the first meeting. In many states a large deposit comes with legal deadlines for permits and a start date. Disclosed by **0 of 15** plumbers below ### Payment schedule Payments should follow finished stages of work, never get ahead of it. Disclosed by **0 of 15** plumbers below ### Warranty: what kind and how long Structural, materials, equipment and workmanship warranties are different things. Check which one the number refers to. Disclosed by **0 of 15** plumbers below ### How changes are priced Changes after signing are where budgets drift. Ask for the method in writing: fixed price per change, or cost plus a markup. Disclosed by **0 of 15** plumbers below ### Proof of insurance Ask for a current certificate of liability and workers' compensation insurance, sent by the insurer, before work starts. Disclosed by **0 of 15** plumbers below ## Section 3 Comparison table All 15 plumbers, listed alphabetically; the order is not a ranking. A dashed Not provided cell means the business hasn't told us and we couldn't confirm it from a public record. Not offered means the business told us it doesn't offer it.

[Read the Washington cost guide for plumbers](https://theopenbooklocal.com/guides/plumbers-cost-washington/) ## Section 6 Questions to ask before you sign Each question matches a field on our sheets. If a sheet says Not provided , this is where to ask. 1. **What exactly is in the price?** Get a line-by-line list: permits, materials, equipment, disposal and cleanup. 2. **How much is the deposit, and what are the payment stages?** Each payment should be tied to finished work you can see. 3. **How do you price changes after I sign?** Fixed written price per change, or cost plus a markup? What is the markup? 4. **Which warranty covers what, and for how long?** Ask for the warranty document itself, and whether it transfers if you sell the house. 5. **Who does the work?** Which parts are done by your own crew and which by subcontractors, and are the subcontractors licensed? 6. **Can I see your license and a current insurance certificate?** Check the license yourself on the state's license lookup, and ask the insurer to send the certificate. 7. **What happens if I cancel?** Before permits, after permits and after work starts: what do you keep, and what do you refund? 8. **When could you start, and what delays the finish?** Get the start date in writing, and ask how weather and inspections are handled. ## Section 7 Frequently asked questions Which plumbers in Washington are included here?
