The Original Plumbing Company Satisfied Customers!


 

5 star ratingVery professional from start to finish. The plumber who came out wore a mask the ENTIRE time!! Was very cautious and also wore gloves properly. We called this company and they were able to come out the next day. Upon arrival the technician was covered up for our safety and his. After reviewing our issues he was straight forward and did not push us to do work that was not needed. He was able to resolve our issue right then and there and you wouldn't have even known he was here when he left. Respected the orders in place due to COVID and extremely reasonable when it came to the resolution. Very happy we contacted them especially considering the precautions needed during this Pandemic time. Definitely know who to call next time we have any plumbing issues.

5 star ratingGreat customer service!!  Joel came out at 6pm Friday night to identify problem, but needed parts (old breakers).  He identified a safety issue from a prior modification and fixed it.  He was thorough, communicated well, and the charge for parts and labor was less than $300 - very reasonable.  I highly recommend them and Joel.

5 star ratingI cannot recommend these guys highly enough. All day we were dealing with another plumber who wouldn't return calls and had already made us wait all the day before and never showed. We called Joel at The Original Plumbing Company and he had someone out within the hour. These guys are professional and courteous. The problem was diagnosed and we were told the various routes we could take to repair the problem. The minute we authorized work the work began. These guys had everything they needed on the truck, none of that "Let me get a part and my office will back call with a schedule for the repair" stuff. The job was done in a couple hours and we were back up and and in business. I highly recommend Joel and The Original Plumbing Company. Top Notch outfit here.
