Our verdict
Fast emergency response with honest pricing, but rare no-show incidents and one 12-year-old overcharge complaint create hesitation on larger jobs.

Red flag
Two no-show or incomplete commitment incidents: one reviewer taken off work on scheduled date with no show/call/followup (2019), and another experienced a quote appointment that turned into just a quote rather than scheduled work (2021)

Cited in 1 of the 103 reviews we analyzed.
Communication breakdown on quote follow-up: one reviewer scheduled a quote, received an invoice a week later with no contact, had to clarify it was a mistake, and never received the actual quote

The evidence — in reviewers' own words
Critical
“They will try to take as much money as possible from you, get different estimates from other plumbers. They wanted to charge me $2800-$4800 for a sewage problem. When I called another plumber for an estimate he came out and fixed the problem for $500. I know this review will be taken down since Yelp allows the business owners to do that but if I could help just one person to stay away from these con men then my job …”
“I had them out to quote a project. No contact until a week later when I received an invoice. I asked what it was and they said it was a mistake. I never received a quote. I'd give a one star review because it wasted my time and I had to maneuver my schedule, but that's just mean when they have so few.”
“I contacted Andersen Plumbing on 9/27/19 to schedule a bathroom faucet installation and rodding. Appointment was set for 10/2, so I made arrangements to work from home that day. Greg Gazda showed up, looked at the sink, and provided a verbal quote. I had been expecting to have the work done, not a quote provided, but whatever. Greg offered the next Monday, 10/7, as the day for the work to be completed. I texted him …”
Positive
“I have used Andersen a few times now. They have serviced my home once and my business twice. They are easy to schedule, seem reasonably priced, and are honest. They have also provided less expensive solutions to our problem than other plumbers have. Highly recommend.”
“I appreciate the level of transparency of what needs to be done. I choose Andersen Plumbing, because I know they take pride in doing doing a great job, and they care about the customer's experience. It's the simple things, like having shoe covers ready to go without having to be asked. They're great!”
