    Nick, Corbin, and Kody did fantastic work. As a DIYer I was on the fence about hiring a large company for a job I knew I could do myself — no regrets at all. They installed a new sink, faucet, valves, dishwasher supply line, and garbage disposal, plus all the plumbing to go with it. Removed the old stuff and hauled it away. Cost was ~$1,450; I supplied the sink, disposal, and faucet. Fast, too. Nick came out the next day to quote, and everything was done under a week start to finish. Two things worth knowing: there’s a ~$65 quote fee that’s waived if you hire them, and you get text updates and a call when the tech is en route. Professional, reputable, and I’d use them again.

    My house wouldn't drain a red solo cup. Till Nick and Aiden. The super twins fixed me up. Very professional and I trust them for future work.

    Gabe and Aiden were polite and professional. They diagnosed and fixed the issue on the same visit. Price was fair and they did a great job explaining the issue,

    We had a sewer problem where our drain in the basement kept backing up any time the washer would empty out. Ryan came out and took a look at it and after running a line he deduced that we had a separated pipe which he then said would cost $4900 to fix but he was going to discount the $630 he charged just to snake and run a camera. Two issues I have is that the issue was not fixed after spending $600 and he incorrectly diagnosed the problem. He also said that he could only get his camera roughly 30ft down the drain. Before we authorized the work, we had a second plumber come out and he was able to run a 65ft camera line through our pipes to where we saw no damage whatsoever. We found out that the issue was our stack was not properly vented. After installing an additional AAV for less than $50, our problem was completely fixed. Ryan was extremely friendly but I will say the job was not thoroughly done and I don’t believe this job was fairly priced. UPDATE: Cardinal was prompt and proactive about solving my dissatisfaction. Austin came out and gave complimentary service and they really integrated my regards as a learning experience. I am well pleased with the company’s professionalism and their handling of misunderstandings.

    Stop reading reviews and go with Cardinal Plumbing! They beyond exceeded my expectations. First the lady who answered the phone was very nice and personable. See was easy to talk to and listened to my whole story. They set me up for the next day. And I'm 40 minutes away. My husband met with the tech and said he was very nice and he liked him. Which my husband doesn't normally like anyone. These were the 3rd plumber we've had out. The first was roto rooter and they said to call a real plumber. Then the other plumber wanted to charge me almost double what Cardinal charged me. I recently saw a post recommending them in a local fb group and I'm so glad I called them. You won't be disappointed!
