Compare quotes only after checking that they cover the same investigation, repair, testing and exclusions. A lower total can hide a different scope.
Start with the problem you observed
Describe the affected fixture, timing and safe access. For a Seattle-area address, have the utility name and parcel information ready. Do not ask competing businesses to price a concealed repair as if its cause were already known. An initial diagnostic visit can be a separate paid service; confirm that charge and whether it applies to later work.
Put investigation and repair on separate lines
A useful quote explains what the assessor will investigate and what evidence supports the proposed remedy. Ask for the specific component, material or equipment, the access required and the testing planned afterwards. If a wall must be opened, agree who approves the opening and any expansion of the scope.
Find what the number leaves out
Disposal, drying, cabinet or wall repair, permits, inspection and other trades may be excluded. Ask explicitly rather than assuming the phrase complete repair includes every task. For a rented or shared building, document the person who may authorize work and water interruptions.
Compare equivalent proposals
Mark which items are included, excluded or still unknown in each proposal. Ask about warranty terms and the process for changes without treating either as a website guarantee. The comparison tool below calculates no repair price; it helps identify missing questions before you choose.
Seattle-area preparation
Use the supplier on your bill and the full street address to identify the correct utility and permit jurisdiction. For shared buildings, establish authorization and equipment access. Washington L&I has different plumbing qualification scopes; verify the business and the person who will perform the requested work rather than assuming qualifications from a service-page label.
Compare two supplied quotes
Enter each written total and any known excluded work to the nearest cent. Use zero only when the business confirms no additional charge. Unknown exclusions prevent a fair total comparison.
