Recommended Customer Reviews

This is as good as it gets. From the owner David to Debbie the office manager to Mike and Joe the technicians and to Rene and Javier that does the REAL HARD grunt work....you could NOT ask for a better group of people. Sewer Rat Plumbing should be a household name. I am grateful that I know exactly who to call to resolve any of my sewer issues.

Made an appointment, but the office manager who took the appointment made an error and set it for the wrong day. When I received a voicemail indicating an error had been made, I called back. The office manager insisted it was my mistake (even though I distinctly recalled the conversation), and made a snide comment that she didn't ""have time for this crap."" Stunned, I asked for the owner to give me a call back. In response, she told me to take my business elsewhere and stated she was ""an owner."" I wish I had the opportunity to speak with the real, managing owner, as all that was needed to fix the error was setting it for the right date, without all the attitude.

Each time they come to handle my problem same day that I call. Their prices are reasonable. They have not charged me if the problem is insignificant. I have not needed to call back because their work works first time. They have snaked my line twice, replaced a toilet seal, and fixed a broken toilet. Will call them next time I need a plumber. The receptionist, yes someone answers the phone, is super pleasant. Joe was here the last few calls and he's good at his job.

Sewer Rat was tremendously helpful fixing the sewer lateral in our new home. They're knowledgeable, reasonably priced, communicative and had great follow through - everything you would want from a plumbing company!

i live in a flat in an old house in the mission. my landlady lives right below me. i've been here for almost two years and we have never had plumbing issues.
until recently.
about a month ago i noticed the toilet flushing a little sluggishly. hm, peculiar. i didn't think too much of it until i was face-to-face with backed up disgustingness from my landlady's toilet (which is weird because girls don't poop, heh). in the past two weeks we have had plumbers from Sewer Rat pay us several visits, though i don't think the subsequent second and third visit were due to errors on their end... just old plumbing, i suspect.
FIRST VISIT: a young man came, unclogged our toilets, said we have a 30-day warrantee
SECOND VISIT: an older gentleman came, unclogged our toilets again, flushing heaven and the visit was included in the warrantee!
THIRD VISIT: i'll let you know, he's here right now
but we did learn that the 30-day warrantee means you get one free phone call in the 30-days after the first visit. i can't speak to the pricing because my landlady is obviously incurring the cost but she did mention the first visit was about $200. my landlady and i had no problems with the plumbers who came and i think they may have arrived a little later than they anticipated but to be honest, i don't really care. they deal with other people's pee and poo all day so if they want to show up 30-minutes later than they said they would, fine by me.
do you want me to stop talking about gross toilet issues?

Caution: stay away from Sewer Rat! The owner is a nice guy until he sends out one of his crew that is completely incompetent and too lazy to replace a $3.00 part..... . His crew's shotty repair caused a massive flood in the middle of the night and 10's of thousands in damage, and the most dispicable part was that the owner (Dave) didn't even take the time to come see the damage or respond to the emergency call when it happened.
Obviously, we'll never use them again and if you want a competenant plumber you won't use them either!

The servicemen seemed nice on the phone and in person but the woman I talked to on 2 occasions was rude and very unprofessional. She is sure to drive off a good share of business for these guys. I think she's the wife of one of the plumbers. They better hire someone else and tell her to find another job (maybe a prison guard/bart police?).
I manage property that has frequent sewer/plumbing needs. I would have used these guys for years and years if only she had showed some common courtesy for the customer. Instead she ended up YELLING at me on the phone. My payment was revoked as they did not honor their warranty.

super fast response, Mike was nice and fixed the problem quickly! thanks so much!!!

Often, the only thing worse than having a plumbing problem is trying to find a competent, honest, affordably priced plumber. I am so thankful I found Sewer Rat (thanks to my neighbor, thanks to his father in law). They have been extremely competitively priced on both small jobs (snaking drains) and big jobs (pulling a new sleeve through our sewer pipe). They are also expert, polite, come on time, clean up after themselves, and take credit cards. It's nice to feel happy after suffering through a nasty plumbing problem.

The problem was not the plumber--he did his job. What made the experience unnecessarily unpleasant was the operator/dispatcher. On two different days I spoke to her, and each time I was met with the thinly concealed hostility of a truly wretched person. Absolutely rude, rushed, rancorous. Such toxicity should be flushed away, not leaked back to a customer paying full fee.
