Any legal deck contract must set specific dates for the project to start and finish. This date will be given to you by the contractor to fit into the company’s schedule and should represent a realistic time frame for your project. In construction, the weather and other unforeseen conditions can often slow down a contractor’s schedule. You will want to find out what will happen if the project is significantly delayed. Will you be given a discount or be able to back out of the contract without a penalty? If you need your deck by a specific date like a graduation party this may be a crucial detail for your agreement. You will want to try to be understanding and patient but the stated dates are listed on the contract for good reason. It is ultimately the contractor’s responsibility to ensure your deck finishes on time. Your contract will offer you some assurance that your deck will be built in a timely manner.
