Alto Sewer Services sent Devin out to our home on 2/5/25 for a blockage in our basement floor drain under our utility sink. He initially opened a capped pipe to drain the standing water by breaking off the cap as he broke his adjustable pliers and his pipe wrench was not working for the cap. The initial snake he brought in was too large to get into the floor drain so he was going to leave because he cleared the water by accessing the capped pipe. We asking him to clear the stoppage as thatâs why we contacted our warranty company. After using a smaller snake he cleared the floor drain and attempted to find the source of the clog in the utility sink ask that wasnât draining either. He opened the right basin trap side and was struggling with the left side. He inserted the pipe wrench inside the pipe and pulled the flange off the concrete basin. Immediately he started apologizing and said they would set up with the warranty company to have a plumber come out. We didnât know he wasnât a plumber AND they told me I *had* to sign a work authorization so he could work on the home. Well when the home warranty company, myself and husband spoke with Zach in dispatch with Alto he simply said that they werenât liable as I signed a waiver. I wasnât presented it as a waiver, also super fine print says theyâre not liable for faulty plumbing or defective pipes. Not improper use of tools by their technicians breaking our pipes! After Zach said they werenât liable he hung up and they wonât take further calls. I very much caution anyone from letting them work on your home.

I had a great experience with Alto Sewer Service. We had a main drain blockage with water backing up into the basement on the weekend (Sat. morning) following thanksgiving. The service I used previously had nobody on call or available until Monday. My call to Alto was returned quickly and the office person was great. The technician Frank, arrived in no time and did an outstanding job. Frank explained why the issue occured and provided great information on eliminating future issues. I'll be scheduling Alto Sewer Service for preventetive maintenance and I highly recommend their service!

It's near impossible to get emergency service on Sunday, but fortunately I was referred to Alto Sewer Service. Not only was their technician Dylan, able to get to me promptly in SW Minneapolis, but he was very informative, pleasant, and the charge was less than what I expected. I will definitely use them again, and can recommend to anyone with confidence to use their services.

It is never fun to have a plugged or slow flowing drain. My basement bathroom sink was plugged. It had been draining slow. This morning it was PLUGGED! We send so many of our customers to Alto Sewer, so I knew who to contact. Alto dispatched Frank and he cleared the drain in short order. Great communication, clean work, and excellent results. Call Alto Sewer if you have drain issues! I don't have a good photo to post, and who really wants to see photos of a clogged drain????

Outstanding service and problem resolution. Our sewer line backed up and they arrived promptly, identified the issue, and cleaned it out. The technician was friendly, knowledgeable and efficient. What was an unpleasant problem turned into a great experience. Thank you Alto!

On 4/15, we had an Alto technician come to out to clean out our blocked main line vie the floor drain next to our washer, as other companies have done since we bought the house in 2009. In retrospect, we should have questioned the first the when he only got to "60 to 70 feet" per his notes on the invoice, when the full line is a minimum of 100 feet. We paid $250 with a 30 day "warranty". On 4/19, after a shower and running a load of laundry, the floor drain (again, connected to the main line within 2 feet) led to water again in the basement. I called Alto dispatch, told them what happened, and they said a tech would be out soon. I have never felt so unsafe with a tech before. The tech who came that day asked me if I was HOME ALONE right away. I immediately called my husband and had him on speakerphone for the rest of this. The tech told me, after running water for 10 minutes that I was faking the backup (there was water on the floor!!!!). He was so aggressive and so awful and I just kept asking him to leave. He refused. He only left after his "supervisor" was put on speakerphone with me and him. I should have called the police in retrospect. Not only was the first tech lazy ( We have previous work orders that explicitly show how Alto was incompetent), but they sent a tech into my home who threatened me. It took a call that day to another company who actually could do their job to get the line cleaned out. Alto owes us money. Be careful. Not only did they not fix the line the first time, they sent a tech the second time who harassed and threatened a mom.

Dylan came to our house last night and helped fix the broken seal under our toilet. He was very friendly and allowed my husband to watch him and learn. He quickly solved and fixed the problem. He had a great attitude and came for an odd time appointment from 4-8pm. We highly recommend Dylan and this company for plumbing repairs! Thank you Dylan.
