A private contractor and I changed and added modification for a small bathroom remodeling project . The original quote before the start of the project was 1290. Then after the project was fully completed with add-on modifications the total came out to be 2080. The add on costs were never verbally approved nor written in agreement. He simply told me that he will bill me to calculate how much total he would add only after completing the project. The project also went over the 2 day project he quoted me verbally and took entire 5 days and even requests me to give him a ride to grab a lunch and drive him to Lowe's on own time which i agreed to do. I paid the 1290. And i told him I will pay the rests if I can have more funds available. And he has charged 10% on the remaining fee. Is anything the contractor did legal within his own right?
