Recommended Customer Reviews

Great customer service! Dispatcher was so helpful and technicians came when scheduled which helped plan my day accordingly. They finished and fixed my problem and had my toilet working in no time. Would definitely use them again.

The sewer lateral was replaced 3 years ago by Dave from Sewer Rat. This past week, we had a major blockage in our sewer lateral that resulted in raw sewage backflowing out of our clean out onto our property. We couldn't use our toilets, sinks, washing machine, etc for a total of 5 days. Life was miserable. I contacted Dave and he came out as soon as he could to clear the blockage. Dave is a straightforward no nonsense guy who wants to get the job done. After snaking and putting a camera into the sewer lateral, he managed to clear the blockage. He said since he did the original work 3 years ago, he wouldn't charge me. That is solid service.

We used Sewer Rat a couple of times in the past. Should have checked recent reviews. I just had new grout put in a shower so was sparkling clean. It was draining, but slowly. Appt. was arranged in timely manner & tech arrived within window. He didn't give his name. After 40 min. he informed me it was now totally plugged, probably from rust. He gave me with no suggestions on how to fix the problem. What upset me was the horrible mess --- closed to two inches of rusty, brown water in the bottom of the shower. When I questioned him, his response was ""it wasn't working before"". I talked to Debbie in the office & her response was the same. When I asked if I had to be the one to clean up the mess, she answered "" I can have the supervisor call you next week.""
Cross them off your list. Never again.

When it rains, it pours...Our washing machine was not working and when trying to figure out the problem, I also noticed that the faucet/valve supplying the cold water to the washer was leaking. I first called Noel Appliances regarding the washer. It was a relatively easy repair, but he had to order a part. He suggested that I get the leak fixed while we waited for the part and he recommended Sewer Rat.
I called on a Thursday, hoping to get an appointment on Friday my roommate was working from home. I explianed that he had to be on a call from 12-1pm so we needed to make sure that the work was done by then. Debbie, who answered the phone said she understood and would check the schedule when she got to the office, but she thought she could give me a 9-11am and would call back to confirm.
Debbie called back within 2 hours and said that she could give me an 8:30-9am window to make sure the work was done by noon. She explained their rates were hourly plus parts.
When Friday came, the plumber called and asked if he could come early. We said sure and he arrived a few minutes later. He was friendly, professional, and fixed the probelm in less than an hour. He also connected the new hoses that we got for our machine.
I highly recommend this company and they will be the first one I call next time I have a problem.

Called this morning and didn't get a call back for 2 hours but Joe came out even before the time window that they quoted me for the afternoon. He doesn't have a good bedside manner but knew what he was doing, worked fast and kept things neat and clean. Definitely one of the cheapest for jetting out your sewer line in SF!

They get 1 star for the obnoxious telephone service. I have been a loyal customer of theirs now for about 6 years since they fixed the main to my apartment building. I called to make an appointment for today to have the main cleaned out. Debbie said they had service between 1 and 4. So I made an appointment. Come to find out when I called back at 3:45 that the appointment was for Monday. Debbie was extremely rude to me so rude I will never call them again. Actually she cancelled my appointment for Monday. I guess they are so busy the don't need my business. Too bad guys I guess there is always someone else that is nicer...

David from Sewer Rat solved a problem involving a complex plumbing issue at my office. I had consulted with several experts to try to solve the problem, but no-one could come up with an answer. David methodically evaluated and identified the problem and in a short period of time solved it. He made solving the problem look easy. He saved me a lot of money. Friends had given me the recommendation to call Sewer Rat.
If you have a tough problem to solve, your best bet is to call David at Sewer Rat.

Showed up on time.
Gave friendly and good advice on problem with water heater.
Would definitely call again.

Wow! I called this business after my next door neighbor recommended their services, he is a contractor I might add. A small business owner myself, first impression lasts and why I bothered to waste my breath with the first point of contact to this business I do not know. The woman who answers the phone is rude and obnoxious. I inquired about a sink blockage and was given their hourly rate, minimum of one hour regardless and when I tried to explain I needed the pipes underneath replaced she got annoyed with me and told me she could not answer anymore of my questions. I'm sure this woman loses this company hundreds of dollars a day with her short fuse and complete lack of customer service skills. I called a local plumber who was pleasant and eager to please, professional, on time and fixed our problem with a smile and all at an affordable flat rate. Do yourself a favor and call someone else who will treat you with respect and not bite your head off. Disgraceful way to do business.

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.
