Coronado Excavation offers an unconditional 5-year fully transferable warranty on every full sewer and water line replacement we do. We assure our customers that we will perform our best work for you the first time. If during the five years, any problems arise, our priority is to take care of any issues pertaining to the work we did. Also, if you sell your home, this warranty will be transferred to the new owner. This is the Coronado Pledge to you.
