Repair-shop disputes generally come down to the same things: the written estimate, what was actually authorized, and the final invoice. Organize those facts and get a free letter outline; the full demand letter is in the $39 Case Pack.

In Washington, all repair estimates exceeding $100 must be in writing and include the date, shop and customer contact information, vehicle identification details, a description of the problem, and a choice of parts alternatives. Before providing parts or labor, a repair facility must give the customer a written estimate, unless the customer signs a statutory alternative form choosing to waive it, set an oral-notification price ceiling, or decline any estimate. The facility may not charge more than 110% of the total shown on the written price estimate (i.e., a flat 10% overage tolerance), exclusive of sales tax, unless the customer authorizes exceeding it. A written estimate is not required for the repair of vehicles with historic/collector license plates, though the customer may still request one. Every repair facility must post a statutory rights sign, and both estimates and invoices must be retained per RCW 46.71.060. Failure to comply with estimate requirements bars the shop's lien rights under RCW 46.71.041.
