Junk company. The plumber was 1.5 hours late (they forgot the appointment and I had to urge), and when he arrived he stated that this type of problem (backlash in the drain) they usually fail to fix. Had to call car wash and wait 1 hour until the middle of the night. A total of 4500 for plumber + 4500 for flushing car.

A serious company would refer to the car washer on the phone instead of taking the job and billing roughly for a problem they know is probably not going to fix.
Steer away!
