A Construction Estimate Disclaimer serves to limit the contractor’s liability in the event of a construction project gone wrong. It states that the estimated cost is based solely on what the contractor knows at the time of the estimate and that any unforeseen costs or delays are out of their control. It also reminds customers there may be additional costs if they choose to change the scope of the project while it is underway. Ultimately, the disclaimer helps protect contractors from liability if the project runs into any unexpected problems.
