Why should I get a written contract?

Without a written contract, there is no way to ensure that your expectations of product, installation, project scope and pricing are being met.

Remember that proposals from different contractors may look as different as apples and oranges! Don't be shy about asking any contractor to clarify the proposal. Ask lots of questions and each contractor the same questions for consistency.
Insist upon a written proposal. Examine it to make sure you think it is complete and fair. Do not settle for an oral agreement on any of the work to be performed. Have the contractor document all points clearly in writing.
At Exovations, our detailed proposal becomes our contract so that you can clearly see what you are getting and what it costs. No surprises.
