As an investor and GC I understand both parties frustrations.. one having dealt with horrible contractors on my own properties and then having at one time good contractors, botch a job that they were subbed out for.
So while it isn't ideal.. Lynn, you need to make it right, even if it cost you 5k because in the long run, it will cost you way more in lost business by not fixing it. Not only that, but you've got the opportunity to turn a bad situation into a win all the way around. But it won't be a win, if you let the fire keep burning too much longer.
I agree with Mark, that the only way to completely avoid this is supervision, which is NOT ideal at all. But is the ONLY way to stop it from becoming a problem, where you can address quality control issues immediately and terminate if necessary, sooner rather than later.
So you have 2 sides of the coin here as a contractor- Either large volume of work where not everything can be 100% supervised or small batches of work with a higher rate of supervision. It is the GC's job to patrol this.. If you choose the first option, large volume, you're going to have to budget for mistakes, and Make them right.. because lets be honest, -**** happens. It's a cost of doing business. But FIX IT and REMOVE the SUB.
Donald, sorry to hear about the issues, I hope they step up to the plate and do what is right.
