Hi. Wildly different quotes usually mean different scopes. When we got quotes for our Seattle Siding Installation project, GotRot's estimate was clear about what was included: removal, disposal, repair of any damaged sheathing, house wrap, flashing and trim. Some cheaper quotes didn't include rot repair at all. In the end, the clear estimate saved us from surprises. Honestly, compare line by line, especially how they handle surprises underneath. We chose clarity over the lowest number, and we're glad we did.
