It is certainly reasonable to try to negotiate a lower price with a contractor.

You should keep in mind, however, that there might be differences in where and how the contractors hire and pay sub-contractors and work teams, the quality of the materials used, and the quality and workmanship achieved in the final result.

You might begin by asking why the contractor’s price is higher than another quote you received. An honest discussion will help you understand the preferred contractor’s pricing. It might also help you identify ways to reduce the cost of your project by making some minor changes or by becoming more involved and doing some of the work.
