In Sept. of 2010 contractors were installing aluminum siding and gutters on our home on Long Island, NY. The job took a week or so and they were responsible for removal of debris during this time. The contractors neglected to remove broken wood with nails protruding from it and I stepped on the rusty nail left in my driveway. The contractor was present and witnessed this. I received medical attention at a walk in clinic - including a tetanus shot. I am currently under a Podiatrist's care Due to the trauma my foot has produced fibromitosis and discovered I now need surgery. I would like to file suit against this company - how would I proceed?
