Don and his crew recently remodeled two of our bathrooms which were over 30 years old. He spent quite a bit of time discussing options with us and helping us make decisions on tiling, bathtubs, toilets, vanities, medicine cabinets, and light fixtures. He estimated one week for each bathroom and they were right on target, even finishing up a day early on the second bathroom. We were very impressed with their professional work ethic. The crew was here early every day and cleaned up every day before they left. Don also worked with me on several issues that needed to be handled, such as old lighting issues that needed drywall work. Each instance included letting me know what they were dealing with and making sure they had a solution I was comfortable with. He was also on target with the estimate and gave me all the receipts from all the purchases. We would definitely recommend Knowles Contracting to anyone who wanted an excellent contractor who does a very thorough job!
