Bill's handyperson service

We used Bill Bishop for a bunch of work in our house including drywall, electrical, flooring and painting. Bill always seemed to be a straightforward guy and fairly knowledgeable. When the work was being done, we noticed the workers did not really seem like skilled tradesmen. Well, now that months have passed since the work was done, we have noticed a number of problems, including air drafts, water leakage and even a door that swings open by itself (poorly mounted). Bill came by once to take a look, but didn't really follow-up or take interest. Seems like he just "moved on". Hard to recommend someone like that...
