1 cited review

What reviewers report — the concerns
Other directories bury these. We think you should read them before you call. Every concern below comes from the reviews it cites.
Quote bumped $75 after service without prior notice (2 couplings charged extra); customer relied on office staff to recover
“I was quoted 230$ initially then plumber ended up charging 250 plus 2 couplings 50$ additional. I thought that was steep for 2 couplings — 75$ extra unanticipated cost was not in my budget.”
Poor workmanship flagged in multiple Yelp reviews — tech didn't resolve issue on first visit and wanted additional charge; no-show on estimate then late arrival
“Unprofessional, incorrect information given by operator on initial call. Didn't fix the issue with the first visit, had to come out again and wanted to charge an additional amount for something that was still broken.”
