If you find yourself unhappy with the quality of work done in your home, You first need to determine if it is cosmetic or improperly installed.I would call a home inspector to look over the project to determine quality. If it is cosmetic , ask yourself if you approved the material used and if it was installed by a professional. if it is your approval you don’t like i’m afraid you will either have to live with it , or change it. if it was the install , negotiate with your contractor for a remedy. Good Luck!
