The tech was prompt and did excellent work.
Michael Jones
I had solid plumbing & drains come out to make some repairs on the drains for both my toilets and replaced my outdated laundry box that was not working. The techs Emmanuel and Mario were so professional, fast, and knew exactly what the problem was. They even went the extra mile and hooked up my washer and dryer once they finished the repairs. Everything works perfectly now. Solid service, fair pricing, and real attention to detail. I’d highly recommend them.

I needed a plumber to take care of a main line back-up on a Saturday. The team responded promptly, was very professional, and took care of the issue all in one visit. Thank you!
Jennifer French
I had some landscape drain problems. Had one of the TV big company over and they essentially said they needed to bust up my concrete patio etc etc and they would not touch a lateral drain. Got in touch with Mario and had a great conversation with him on the problem. He came over with his crew Emanuel and Angel. Mario diagnosed the issue and created a plan of attack. The main drain line was full of roots but he got them and the issue if FIXED. They were pleasant to deal with, very professional and did a great job. I will definitely go back to them for any further inside or outside plumbing problem! Thank you Mario!

Mario and his crew were extremely professional and very thorough during their job. We had sewage back ups and burst pipes and they worked quickly to get the job done. I would 100% recommend Mario to anyone with plumbing concerns.

Solid Company & Drains Representatives reported as scheduled and came with an attitude of getting the job done. They secured their ladder, hopped up in the attic and within 5 minutes Mario had determined the problem. He took pictures of the area and sent them to me on my phone. He explained each photo. Incredible! Additionally, he suggested that I get a specialty company to use special tools to determine if there is additional water damage in the wall area that they could not see. I really appreciated that suggestion. Thanks to Mario and Angel for their professionalism, friendly attitude, and great plumbing skills!

Emmanuel and Angelo are the best team! They showed up at my house in El Cajon within 30 minutes of calling. We had been dealing with this issue for almost a year, and they were the first ones to actually figure it out. They ran a camera down the drain, found the clog right away, cut out the damaged pipe, and replaced everything properly. Great pricing, super professional, and easy to work with. Highly recommend Solid Plumbing & Drains!

i hired Mario and his crew (Emmanuel and Angel) today for a landscape drain issue after turning away one of the big TV companies that essentially refused the work. Mario showed up on time, reasonably diagnosed the issue and made a game plan. In the end he was able to clear the problem! They left the job clean. very professional and job well done! thank you!!!

Linda A.Verified
I had a patio drain that was very sluggish. Mario and Angel came and took 2 hours unblocking a mountain of mud from down the line. They were professional, resourceful using multiple pieces of equipment and persistent working till the blockage finally gave way.They also had to go through my house to get to drain and they were very neat laying down plastic to protect my floors. I am a very happy and highly recommend them.
