If he is legit that is a great price.
Agreed. It makes you wonder...
I would definitely check out his previous work.
Do your homework. If you aren't aware of how things should be done, find out, do your research, and inspect what he is doing every step of the way.
This is your house. Don't be shy. Make sure it's done right. That's what I am trying to do. I am researching everything he is doing, the materials he is using or wants to use, etc.
Get a detailed contract on what specific materials you want used (type of drywall, type of insulation, vapor barriers between wood studs and concrete floors & walls, etc.) and the specific processes involved, etc. If I had it to do over again, I would have gotten more details on what materials were to be used before construction started, because I've had to discuss this stuff and change some things with him as we go. I guess it's not a huge deal, but it just would have been nice to have it all mapped out before hand.
I've learned a ton from this whole process.
My contractor is pretty good I think. I'm out there almost every evening at the house to check on the work done each day, and I go out there a couple times a week during the day (over lunch) when he is there to talk to him about stuff and point out concerns/ideas/etc. He's one of those old school builders who seems to take pride in doing things the right way. The process has been a slow one, but I'm happy with the quality of work.
I'd recommend him to you (after he's done with our house of course
), but he's out of Edwardsville...so you're probably out of his service area.
