I hired a contractor to refinish a pool. Quoted 3 days took over 30 because of no shows. $4200. Have paid most of the money except the final payment Because I'm unsatisfied with the final product. Apparently she never pulled a permit. I've told her I would pay if she gets a manufacturer's rep out here to let me know that this finish will clear up over time (which she agreed to but did not do). She has come out several times to vacuum and clear up and scrub the pool surface with no change. She is now attempting to charge me for these visits. She is filing a lien on my son's property. I hired her.
