Mario and his crew at Solid Plumbing & Drains are amazing and I can’t recommend them enough. They saved us from multiple crises when our sewer lateral began collapsing and would be at our house same day, sometimes within an hour, when we’d call them. Mario was always very empathetic to our situation and made sure we understood what the issues were with our pipes, what the repairs should be, what the costs would be, and how to best work with our insurance. We ultimately went with them replacing our entire lateral with a pipe burst and they got it done on time and on budget. Super hardworking, nice, professional guys. They’re definitely our go-to for plumbing. Adrian ATrustindex verifies that the original source of the review is Google. Very difficult situation but turned out great. Thank you for your hard work and expertise. Thank you. David Frank

Based on 115 reviews Mario from Solid Plumbing came in response to a clogged drain under the kitchen sink. We found that the problem was more complicated. Mario explained our options and answered our questions. He used hydro-jetting which was successful. There was a lot of hard work required, and we found the cost reasonable. Mario is friendly, helpful, and very professional. I would certainly contact this company for future plumbing work, and recommend to others as well. Patricia D. Angel did a great job and left zero mess on our main line repair he is a huge asset to his company and I highly recommend Angel Alec H. My sewer line backed up. They showed up, attempted to clear the line and discovered the line was broken and full of tree roots. The owner Mario worked directly with the insurance company and got everything covered. They arrived early to start the digging and replaced the line in a day. I couldn't be happier and saved his number in my phone to call for any plumbing problems in the future. Thanks guys KC K. We love these guys. They are always speedy, nice, tidy, and reasonably priced. We have definitely given their name to friends needing plumbers. Alissa G. This was our second experience with this company and we were really happy! They did a great job the first time so we called them back for a bigger project. Mario is super helpful, always available and very honest guy. He will not try to rip you off like other companies. No hidden charges, no unexpected costs, overall a great choice for plumping! Maria M. I recently had water damage issues and was referred to this local business. Mario and his team of people were very professional and efficient during the initial visit. They came on time, assessed the situation, explained what needed to get done, and also provided me with other referrals for other issues that needed to be done. They came back the following day, and completed the job. Very fast and easy to work with price points. Thank you for doing me a solid! Christine T. We had an issue with our plumbing and Solid Plumbing came and took care of business. Mario and Eric came and assessed the situation and after trying to solve the issue they informed me that things were a bit more complicated but they would be able to take care of the problem. They delivered on their promise and cleared the blockage in a short amount of time. Mario and company were very detailed on explaining what was going on and what they would be doing to fix the issue. Mario and Erica are very knowledgeable and honest with their work. Everything upfront and clear. Will definitely be recommending Solid Plumbing. Carlos R. Mario from solid did a good job. His team was very professional and helped us get to the root cause of our drainage issue. Carlos S. I woke up at 5am to head to the gym where my entire first floor was flooded. Called couple companies and didn't get an answer. Called Solid Plumbing and the owner Mario answered and immediately took my information down and within an hour he had a team member with the right equipment in front of my door step. I was quoted on the spot and work was done efficiently and very professional. I'm very picky with my home and my stuff. I saw personally that this company did train their team properly! Mario can't thank you enough for saving my morning . I HIGHLY RECOMMEND... you'll get @ SOLID TEAM @ SOLID PLUMBING David E. The following review is on behalf of my Dad (Rik A) I had a series of plumbing drainage issues which a local plumbing company failed to resolve after three attempts. My insurance company contacted Solid Drain and Plumbing. They responded quickly and sent Erik who did a scope check and made a quick determination that my main sewer line was plugged up due to root invasion. Mario and his staff contacted me and explained what the project would involve and scheduled a start date. They showed up on time and fixed the issue expeditiously. They also cleaned up thoroughly after they were done for the day. I highly recommend this outstanding company and give them FIVE STARS. Update : After the rains, the ground area where they trenched to access my sewer line settled and left a gaping hole. I contacted Mario on 2/16 /25 and was informed they will fix the issue and that it will be scheduled within the following week. This is another reason why they deserve the highest customer satisfaction rating. They are very quick to respond . Erika A.
