Red flag
Gross negligence complaint: left 14th-floor glass patio door wide open while tenant on vacation; unit covered in pipe sludge on counters, under sinks, and across dishwasher — 1 of 5 analyzed reviews at this volume is a significant signal
“Unprofessional, Negligent, and a Major Security Risk. They left my 14th-floor glass patio door wide open. Leaving a high-rise apartment unsecured and exposed to the elements while a resident is out of town is gross negligence. The unit was covered in 'pipe muck.'”

“Hector from Andersen Plumbing did a fantastic job and was very polite and professional. Highly recommend! Will request him in the future, for sure. Thank you! 🙂”
“Josh was amazing. He figured out the issues, came up with a proposal, purchased everything so we didn’t have to, installed it brilliantly, and even taught us how to maintain it as well as identified other issues that needed to be addressed. Honestly, one of the best experiences we’ve had.”
