Synonyms for "bad work"

[kurt]

This morning I told someone the flashing around the skylite was a total mess and it would leak. I've described brick work as a disaster with catastrophic failure as a possibility.

Also, "completely wrong" (w/the correct method described), "sloppy", "idiotic", etc.

Customers understand it, and like it. A lot.

Realtors hate it, which suits me fine.
