For remodeling and new home projects, allow at least a 10 percent increase for changes from the contract. If changes in the plans or contract occur during the project, put them in writing as amendments to the contract, including any differences in cost. Both you and the contractor should sign the change orders. Change orders are a major source of misunderstandings and cost overruns. Talk to your contractor during the project.
Many disputes happen because people fail to communicate at every step of the project.
If in doubt, talk it out. There are no stupid questions you can ask your contractor. We are continually improving our site. Please check back regularly to see what's new.
