Ken called ahead of his arrival, he looked over my sink and thoroughly assessed what needed to be done. He spent time explaining what was needed to fix the problem and gave me the price. He was very cordial and professional. The work was completed and he showed me exactly what he had done. Ken also gave me some suggestions as to avoid any further clogs. I was very satisfied with his work as well as the price. I will certainly refer him to anyone with plumbing needs.
