Next time, I'm specifically going to ensure another contractor is hired to ensure QC of the home during construction. No moving onto the next stage until the 1 foot hole in the subfloor caused by a falling drill from the 2nd story is fixed.
Anybody, and I mean anybody, can point out little things that are wrong in something. Especially in construction, by people that have never done it themselves but holds financial power. Also, I guarantee all the slight changes he thought were critical enough to warrant constant intervention actually weren’t, or could’ve been addressed later. The cost would have been significantly higher if the contractor factored in the time it took to satisfy him. He was getting what he paid for.
