When hiring someone to perform renovations on your home, they will usually offer an estimate on the cost of materials and labor. When getting a bathroom remodeling estimate take the time to go over it with the contractor to be sure of exactly what is included in the price. In most cases a bathroom remodeling estimate will include a margin of error, but there should also be a section that covers how much of a price adjustment will be allowed by the homeowner or if all changes and additional charges will require the customer’s approval and signature.
