GOOD, CHEAP AND FAST, You can only pick two!!
If a contractor is good and fast he wont be cheap.
If hes cheap and fast he wont be good.
If hes good and cheap, he wont be fast.
I was a contractor for 22 years. I dealt with a lot of subs contractor. The most important thing in hiring a contractor is the ability to control him. But that is only part of it. This may sound funny but, I look at his marital status, financial status, his health, his momentum in business and I call his supplier to see if he pays his bills on time. Of course a good contract. I use an AIA form.
I was consider a premium contractor in certain areas of Brooklyn and Manhattan for many years. Than, in 2010, I was sick for 6 months, the doctor couldn't figure out what the problem was. It turn out to be Lyme Disease. I was sick for many years after that. I was not the same contractor I was before I got sick.
At the end of the day you need to look at the fore mentioned item regularly.
