Princeton Plumbing Pros is truly professional and know their stuff. They were honest and gave me the right advice for unclogging the drain. They suggested installing a more accessible cleanout and offered to do it at reasonable price. I have hired them to perform this task. I like how professional they are with an attitude to delight the customer. I hope to use them for all plumbing issues in the future. The owner is personally involved in making sure that they provide the right solution to address the needs.
