El Sobrante provided very good assessments of the upper laterals on several properties we own. They were prompt and thorough with the evals and providing solutions to our more serious repairs. I recommend them for your project.

Very professional group of workers. They arrived when they said they would and started working immediately, no half hour standing around drinking coffee and talking about yesterday's sports scores bs. They were obviously very competent seemed to enjoy working together. Very efficient in general and with good attitudes, which makes a big difference. They put in the new pipe without incident and once finished, they cleaned everything up and if not for the asphalt patch in the street, you would have never known they had been there. Highly recommend.

El Sobrante Sewer Repair was very responsive and fixed our problem right away. I called as soon as they opened for an appointment but had to book online which I found a little confusing. The father-son team showed up within an hour and explained what was going on, cleared our stopped up drains, and let us know what we would need to do in the future to fix our issue. 5/5 for service and 4/5 just for the confusing part about booking. Prices were reasonable. Would definitely recommend these guys for any plumbing and sewer related issues.

All of the team’s guys, Joe-Scott-Joel and others were extremely talented, friendly and very good at work. I am happy that they successfully finished the sewer lateral replacement within 6 hours and got the certificate from WCWD without any problem.
They deserve to be a 5-Star-Company.
