Can a contractor file a lein on a private property when the small water leak job wasn't finished after 9 months time? They received $1000.00 to begin work..and never finished and no communication to finish it and what was done was very sloppy work and very unprofessional ...now threaten to file lein...and take more advantage of an old lady who is not happy too..Please help me! The balanced is $1800.00
