If you want a contractor who's going to cut corners these are the guys for you. But don't expect them to pass on the savings to you..."that wasn't included".
But it will seem like you're getting more than your money's worth since they will keep coming back week after week after week after week, and again and again, even if it's just for an hour or two, usually Friday morning if you know what I mean. And if they don't finish the job don't blame them...it's not their fault "because the job was harder" than they thought. Oh yes, and they will explain that everyone they know agrees the job was harder than they thought.
In time I came to understand that yes, everything was too hard for them to do. On that point they were finally being honest.
