“Thank you Quandt Plumbing for saving Christmas! We had a drain plug two days before Christmas Eve dinner, Quandt made time to come out, were right on time and fixed the problem. The repair man was also very nice!”
Handled full main sewer line replacement under concrete slab in 7 hours after Roto-Rooter failed — coordinated excavating subcontractor same morning.

“TLDNR: If there was a 6th star, they've earned it. You call professionals for a reason and Quandt Plumbing is as good as you'll ever get. Needless to say, Quandt came out because I had a clogged sewer that Roto-Rooter was unable to fix (filled with gravel). The issue came down to needing to replace my main sewer line from inside to outside my house. After finding out that I hadn't been able to flush a toilet for the last 5 days, Quandt contacted and coordinated with Wally Schmid Excavating and came out the next morning.

“From my experience they don't do good business!!! I know what the home warranty states yes I pay the first hundred. But when u come in for 5 min and say u need ur septic pumped and that's it and still charge 100 dollars for that to me that's bad business. And just to let u know that wasn't the problem the pipe was clogged so that tells me ur company isn't really that good at plumbing”
Denied responsibility for toilet performance degradation after their own reinstall during a remodel — refused to inspect before dismissing the claim.
“In may Quandt came out to do the plumbing work for a bathroom remodel. Most things went well but after they reinstalled the toilet within a couple days performance was substantially degraded. I did my due diligence as the home owner trying to figure it out with no success. I lived with it for 2/3 months hoping it would resolve itself but it became challenging. I then contact Quandt and they were quick to deny responsibility without even taking a look at it. It was an existing toilet which is about a year old. If I would have known of their policy to do the work and deny responsibility on”
