Can I sue to recover expenses from plumbing error?

Plumber jet cleaned my drains to unclog. This action cause a major leak in my drain which required my cabinets and floor to be ripped out. My insurance maximum was $10,000 with a $2,500 deductible. The total from the contractor to repair the leak and replace the kitchen, all expenses, came to $15,484.42. Minus insurance of $7,500.00. So our out of pocket expenses were $7,984.42. Both the contractor and plumber are willing to state the problem was due to the work done by the plumber. We paid him almost $900.00 to clear the drain, which was not done. What is our next step to try to get the plumber to reimburse us for costs due to their improper work?
