Your written estimate is in detail outlining the proposed work. Should the scope of work change, you will be presented with a change order outlining the work needed or changes made to complete the project for your review. Our estimates also include a rock clause as our area is prone to rock in the ground. When encountered and we are unable to use standard excavation methods with a power auger we must dig by hand to break the rock or use a jack hammer resulting in extended excavation time. Please see the rock clause in your estimate for more information.
