Recommended Customer Reviews

Was fortunate to have Jimmy come out to give us an estimate today. Courteous, knowledgeable, down-to-earth, and confident, I appreciated his assurances that they will do a great job.

I had such a great experience with them! Their rates were very reasonable, the office staff was easy to work with and had better equipment to be able to clean, rather than replace, my sewer as another company wanted to do (because their cleaning tool wasn't able to get through everything). Cameron who came out for the initial inspection and then for the cleaning was fantastic!

Sewer Lines Only came out as a second estimate for our necessary repair work. They had a much stronger understanding of engineering and problem solving than the previous company and provided a couple of more affordable options for us. Their work was done well and they replaced our stones and mulch so that no one can even tell we had sewer line work done.

i had sewer lines only at my house today, tyler was on time and professional , i had a small floor drain opened up and tree roots cleared from the main line, it was done perfectly and at the price quoted , i could not be more pleased with the service..... not what i have come to expect in these times......a pleasant surprise

Worked with Cameron who was awesome.
Sewer line maintenance - scope and clean.
Prices were upfront and reasonable.
Work was efficient and on time.
All my questions were answered. They did great work.
Will definitely work with them from now on.

SLO is an outstanding company. Called yesterday to schedule periodic maintenance and they were able to come out this afternoon. I was sent a reminder of the appointment which I confirmed, Tyler was the technician- a polite, knowledgeable professional who wore a mask and was gloved. He was on time, scoped & cleared the line of some roots, remarked about a flat place and small offset, showed me the video, indicated I had no significant issues, cleaned up nicely and was on his way. This took about an hour.
You can find cheaper, but I doubt you'll find better. Highly recommend.

The dug a trench and connected me to the city's sewer line. They did a good job of not messing up my lawn where the heave equipment had to go. I'm connected to the city's main and it all looks (via scope) and works fine.
Where they fall down is fixing all the things they had to tear up to dig that line. They said they would restore the landscaping and fix the area where they had to cut through the driveway (not sure why they couldn't dig under the driveway).
Here is what really happened...They filled the septic tank and area where they dug with loose dirt which 3 months later after the snow and rain has compacted and I still have 2 foot hole in my yard where the septic tank was. The whole line area has lowered as well as the dirt has compacted. They cut a 2 foot way area through my driveway and sent a team to ""fix"" it. That team did a super half-assed job and now my driveway has this crappy, chipped area in it.
All in all, they did what their name claims. They put in a sewer line. Might want to see if they'll discount you a good chunk of change so you can fix the landscaping yourself or higher some real professionals.

Sewer Lines Only evaluated my sewer line inspection report and gave an honest evaluation of the line (at least one other company I called attempted to up-sell me on doing unnecessary work). Kim was very helpful and responded to my request immediately. I really appreciated the professional integrity shown by Sewer Lines Only and will be using them in the future for my sewer line needs!

I highly recommend sewer lines only. They are a professional and thorough company. I have had a lot of problems with my roots because of the Clay foundation and they took the extra step by using a special type of equipment list plus to get rid of these routes. The technician had a scope and included a video after he was done. They charge a flat rate with no hidden fees. It's nice to know that there Are some honest companies in the world

My main line kept clogging so I called these guys for a scope. Really impressed with how honest the techs were. Turns out I didn't need any emergency repairs but I'd definitely recommend for anyone needing work done.
