Red flag
1 reviewer describes confirmed no-show with two rounds of false ETA updates; reviewer concludes 'they aren't honest'
“They made an appointment with me for a 2-hour service window but didn't show and didn't contact me...They admitted they were late but said the service tech was 30 min away in downtown SF. Then 90 minutes later, still no show.”
Red flag
Weekend pricing at $625/hr (minimum 1 hr) confirmed by long-term customer who switched to Roto-Rooter after ownership change
“Because it's a weekend they said they would charge $625/hr. I asked if they charged per quarter hour, but no. It's $625, even if it takes 5 minutes to fix your problem.”

The evidence — in reviewers' own words
Critical
“Be careful with these guys - they aren't honest. They made an appointment with me for a 2-hour service window but didn't show and didn't contact me. So at the end of the 2 hours I called them. They admitted they were late but said the service tech was 30 min away in downtown SF. Then 90 minutes later, still no show, so I called again and now the tech was supposedly somewhere on the Peninsula 50 more minutes away. …”
“I have used Heise's for years, maybe decades, and have always had AMAZING service. I even carry around an ancient Heise's canvas bag. And Mark is great. But with the change in ownership, prices have skyrocketed. I called today to deal with a clogged toilet, and because it's a weekend they said they would charge $625/hr. I asked if they charged per quarter hour, but no. It's $625, even if it takes 5 minutes to fix …”
“The cost to come to our house and do basically nothing was $225. I don't even remember the name of the guy, and I really don't want to remember. Nobody from this place is ever setting foot in my house again. Our tenant downstairs said the shower was not working, so my husband called Heise's Plumbing. They sent someone out fast enough, which is why I was inclined to leave two stars. We also asked him to check …”
Positive
“Mike, Jose and the staff at Heises plumbing are terrific. They are friendly, knowledgeable, trustworthy and always get the job done right the first time. I have used Heises plumbing for years. Thank you Mike, Jose and staff for all you do.”
“Jose was outstanding. He came in and fixed what we had been told by another plumber was an unsolvable problem with our faucet and that our entire faucet would need to be replaced. Instead Jose expertly repaired it, checked the other faucets and installed a new mechanism in our toilet. Not having to change out two sets of faucets for new ones also saved us a ton of money in parts and labor. Can't recommend …”
