    Last week we called Donnelly Plumbing to check and replace a wax seal on our upstairs toilet. Ardacan arrived and was very friendly and knowledgeable. Upon investigation, he discovered that a 65 year old cast iron sewage pipe was spalding and ready to crack and thus explode all over our finished basement!! Ardacan returned the next day with Nick, a new pipe and equipment and took care in opening up the wall and replacing the large pipe. Thank you! Your expertise averted a very messy and smelly catastrophe in our finished basement!!

    Amir was great. He was very professional. He checked out the unit and then advised what needs to be done and the cost. The area was cleaned up after everything was completed . Thank you Amir.

    T J was on time, efficient, and very thorough. He was here to do the annual maintenance on our heater. He answered all of my husband's questions and offered some suggestions. Will continue to use Donnellys. This is part of our annual contract.
