He fixed a crack in our clay sewer pipe, as well as some unexpected repairs where he saw future problems (all for the original quoted price- which was still lower than two other companies.)

Thanks for being awesome!

I honestly can't say enough about this company. This is my second repair with Sewer Lines Only, a…read morecollapsed secondary line replacement in 2024 and a collapsed lateral this month on a 120+ year old duplex in Sloan Lake. I was 7 days from closing on a sale, the line was discovered during inspection. The other duplex owner was rightfully out of her mind because the line ran under her beautiful stamped patio. Sewer Lines Only recommended tunneling under the patio from my property. We had (I'm counting....) 7 very reputable sewer companies quote this job. No one else mentioned going in from the side, and when I circled back to ask, none could. SLO's quote was 25% lower than the next lowest bid (thousands in savings) and 50-75% lower than most bids. So I was hesitant. Enter Joe from SLO - a project manager or engineer? He was so confident they could do this job from the side (really confident, not salesy confident), he made himself available to me at any time to explain the work but never once called me to "seal a deal." He probably took 20 calls/texts from me. I took the gamble and got on a plane to Denver. Jerry and his team showed up promptly for the job, were professional, courteous, and thorough. The line was fixed, no patio or fence demo required. When a possible additional leak was discovered with scoping, Joe came out and confirmed personally that there was no issue. Enter Monica in Billing who went the extra mile to figure out how to split invoicing to bill the other owner her portion and free my property up for sale. And did it gladly. Intelligent, progressive solutions, lower-cost, personalized service - same as in 2024 when I worked with Cameron. They dug a trench in my garage and repatched with concrete. No issues 2+ years in. I'll never use anyone but SLO.

This was a job we have dreaded for several years. We knew a sewer line replacement was coming but…read morethe expense involved really worried us. We had the job quoted on several occasions with bids coming in from 10k to 14k and we always opted to just keep waiting and shopping. We used Yelp to start a "job" and half a dozen companies looked us up. We spoke to four of them then had Sewer Lines Only come out and talk to us. My sister had used them a year earlier and recommended them from the list of possibles. A man named Murray showed up at our house and we liked him immediately. He was honest, funny and simply very likable. He scoped our line and told us we're not in desperate need of a line replacement. We enjoyed the honesty. We had roots in our line and needed to have them cleared about once a year. Not a huge deal but the sewer backups were aggravating and always happened at terrible times. Murray worked us up a quote and we were flatly shocked and dumbfounded at the quoted price. 5k for thirty three feet of line replacement. We started wondering what the catch was. How was this possible? A full half of the best quoted price of the last three years. We took to Yelp and the BBB to research this company and the reviews were stellar as was their A+ BBB rating. A few days later I stopped in their office to accept their bid. That's where I met two more of this companies stellar staff, Monica and Kim. These two women put us further at ease this thus was going to be money well spent. A week later, Pablo showed up at our house with his crew and a skid steer. Pablo treated us like gold and was happy to learn he actually worked for Sewer Lines Only and was not a contractor. This man is a surgeon with a back hoe. They had all thirty three feet dug up and replaced in three hours. We were only minus a sewer line for three hours which really minimized our in house inconvenience. The next several hours were simply waiting for the city inspector to show up. It was very confidence inspiring when the inspector told us that he doesn't really even need to check Pablo's work as he simply never makes mistakes. The trenches were filled back in and tamped down very well. Mi sidewalks, lawn and driveway were cleaned up very well. Murray then returned and scoped the lines to make sure it was all good and he scraped the inside of our cast iron line inside the house. This was an absolutely exceptional experience from the get go. An unbeatable price and first class staff and workmanship. It's nice to have this huge worry off our backs and it came with a five year transferable warranty. Thank you Murray, Pablo, Monica and Kim from very happy customers.
