Good morning- I am the owner of a property in Santa fe NM where a unlicensed contractor worked on a large (4' x 8') shower renovation project that had a hard deadline of 2/18. The shower has non-functioning defective slope so that neither of the two shower head's water reach the 36" linear drain. It cannot be used and needs corrective work to make functional ( estimated cost is $5100 to redo). I have held back $900 of the final payment to apply to the corrective work ( to be done by a licensed shower tiler). He is threatening to put a mechanics lien on my property for the $900. Can a lien be enforced for defective work that requires significantly more $$ to remedy? Thank you for your time and response. Sheila Plunkett 612-669-7828
