Why didn’t the sub-contractor file a mechanics lien?
I would assume because they aren’t experienced in being in business for themselves, and don’t understand what recourses they have. Spazzo probably has the money to out wrangle them in court if their I’s aren’t dotted and their T’s aren’t perfect.
The sub contractor was working for the general contractor, not the homeowner. The sub should have waited to get paid, and never have trashed someone else's property. The sub now owes the woman a nice paint job.
