Homeowners Pinch A Penny, Cost Them A Dollar.

Bodger

I've had similar situations where the H/O gets involved and this type of thing happens. Although I've never seen it this bad.
I think I may look into putting a clause in my contracts that precludes this situation. For dumb-ass H/O's AND their "subs".
Cheap is expensive every time. Seems like the second the H/O gets involved in the actual work and starts trying to pinch a buck, the work goes to sheeite.
