I SOLD & INSTALLED FLOORING FOR A CONTRACTOR WHO WAS REMODELING A HOME FOR HIS CUSTOMER. I HAVE A SIGNED CONTRACT FOR THE PROJECT. I HOWEVER SOMEHOWN MISSED PUTTING THE LABOR TO INSTALL THE FLOORING ON THE CONTRACT, BUT STILL DID INSTALL THE FLOORING. THE CONTRACTOR ACKNOWLEDGES I DID MAKE THE MISTAKE, BUT SAYS THATS ON ME AND HES NOT PAYING AN EXTRA $632.00 FOR THE INSTALL SINCE IT WAS MY MISTAKE.... DOES HE OWE ME IF I DO THIS? IS THIS WORTH MY TIME?
