Mark and his company have been the utmost professionals. We were told we needed to change our septic tank this year. We asked three companies to quote on this project and Mark‘s company was by far the most professional. From the initial visit Mark took his time to explain the process, the potential issues and hidden cost should these issues arise, the timelines and the work required. He provided us with a written quote and was willing to come by and further answer all of our questions. Mark and his team were able to deliver earlier than their predicted timeline. During the installation the crew maintain the site very well and ensured we were kept in the loop every step of the way. They were done in less than two days and left a clean site, fully secure and a working septic system. Mark and his team were polite, clean and efficient during the whole process. They removed their equipment promptly and gave notice when they had to enter the property. I highly recommend Advanced Wastewater and Excavating Solutions to any homeowner who needs this type of work. You are getting more than just a contractor, you are getting advice and an owner who is willing to go the extra mile to put your mind at ease.
