The evidence — in reviewers' own words
Critical
“Tech was scheduled between 10-2 he showed up around 3:40 no communication what so ever on being delayed except when I called numerous times wasn’t able to complete due to supply house about to close at 4.

“Property Damage Caused by Improper Installation of Emergency Sump Pump I am filing this complaint against Dauenhauer Plumbing regarding significant water damage to my basement that appears to have been caused by the improper installation of my emergency (secondary) sump pump by their company.

The rating picture
Newest review in our sample: Mar 2026.
Across platforms
Significant discrepancy between platforms: Google 4.8/5 (8905 reviews) and BBB A+ with zero complaints vs. Yelp 1/5 (1 review detailing major property damage from faulty installation and non-responsive management).
