Derek came out yesterday for our plumbing inspection. He arrived within the specified time range and gave us a text heads up with his picture to identify himself with (we already know him though from prior great experience). Derek is polite, professional, courteous and friendly. He answers all our questions and always provides valuable tips. He is patient and never makes you feel awkward for asking questions. He is thorough and takes his time doing his work. He previously installed a kitchen sink drain line for us, hooked up the icemaker for our refrigerator/freezer unit and installed a valve needed for a dishwasher hookup, and does a careful, thorough job each time. We greatly appreciate Derek's expertise in helping us maintain our home.
