I had concrete work done - it wasn't done to the drawing submitted - he didn't roll the sod (on quote - we kept it - he only cut it) - width is short 8" to 1', outer edge thickness quoted 6" slab - vary 3" - 6".... and list goes on and on. I am trying to negotiate a settlement with contractor. He will only warranty work and complete a repair if I pay full amount. Can the contractor lien property for more than what is owed on original quote?
