“

Orad and his team were great to work with. They showed up exactly when they said they would and handled our extremely difficult plumbing issue with patience and professionalism. I really appreciated that they took extra time and offered to clean up after the work was completed both in the kitchen and basement. I highly recommend O.I Plumbing and will be contacting them for any future plumbing needs.
