Septic System reviews in Rancho Palos Verdes, California

An unbelievable experience added to first use in November 2025, which was “over the top”…& again why Gary became our first choice this time. Fully equipped team, expedient, efficient, forthright and only stopped an honest day of work when job completed not just based on time. Relentless, until causative issue found & repaired. Great team. No one forced me to write anything…I wanted to!!

Gary handled our situation like a pro. We had a cesspool overflow and he took care of it ASAP. Highly recommended!

The service provider was punctual and efficient. He did the job quickly and cleaned up everything after. He was super helpful with the permitting renewal process for the city as well.

Gary was an excellent resource to have on my team. I hired him to do a septic certification and operation permit from the City of Malibu. I highly recommend him!!

My project had been delayed for over a year, the previous contractor kept making excuses and couldn’t get the job done. In my search for others, no one was willing to take on this project…until Gary. Gary came on a Monday, said he would be back Wednesday and finished Saturday. He was completed Friday, he even cleaned the area to the grueling standards of my neighbor. I am completely satisfied withGMP, I can’t recommend them enough, you will not be dissatisfied going with GMP!

Given all the challenges of our particular job, Gary and his crew were able to navigate them well, and get the job done to our satisfaction. They are experienced, professional, take pride in their work, and do all they can to ensure the highest quality.

Called GMPlumbing to get rid of sewage waste and their price was better than the other places I called and they cane next day first thing in the morning and drained our septic basin and removed the old pump. So glad we found these guys- all really nice and got the job done! Thanks Gary and crew!

GMP is very professional, on time and easy to work with. They helped us with water removal from our elevator pit and did a wonderful job. Highly recommend them.

Gary and his team are the BEST. You will not find anyone nicer, more professional, more knowledgeable or harder working. I recommend them 100%. Do not look any further! You are wasting your time. Call Gary and get your job done right the first time! And for a reasonable price too!!!!

Gary and team did an excellent job and really helped me out in a bind. His pricing was reasonable and his team were very professional. Happy with the work he did and would highly recommend GMP for your needs.

Gary and his team were a pleasure to deal with. They were able to diagnose and fix the problem with our septic evacuation pit that another plumbing company incorrectly did. They’re very knowledgeable, super hard working and very reasonably priced. I would recommend them a 100%.

Title: Exceptional Service!

⭐️⭐️⭐️⭐️⭐️

I recently had the pleasure of hiring GMP Septic and Sewer for their services, and I couldn't be more satisfied! From the moment I contacted them to the completion of the job, the experience was top-notch.

The team at GMP demonstrated professionalism and efficiency throughout. They arrived promptly, assessed the situation with expertise, and provided a clear explanation of the necessary steps. Their attention to detail and commitment to quality were evident in every aspect of the service.

Not only did they address the issue efficiently, but they also went above and beyond to ensure that everything was in perfect working order before they left. The level of customer service I received was outstanding, making the entire process stress-free.

I highly recommend GMP Septic and Sewer to anyone in need of septic and sewer services. Their team's dedication to excellence and customer satisfaction sets them apart. Five stars without a doubt!

Gary came to my house and inspected the situation. He was professional, calm, and friendly. He is an expert in his field as he knew what needed to be done from his inspection. He brought his guys the next day and fixed the issue. I highly recommend Gary and his company! Honest, reliable and professional.

Gary was amazing!! He did a wonderful job at repairing a collapsed main drain. He was very knowledgeable and his prices were very reasonable. I would highly recommend him. In fact we are hiring him to do an additional job relocating a septic tank which was an extremely difficult Job to research. Gary was available to answer all of our questions even after hours and on weekends.

We had an issue with the septic tank and Gary and his team saved the day! First off, Gary actually answered the phone on my first call. His team showed up the very next morning and immediately got to work. They were all very courteous, professional, and knowledgeable. I was skeptical that the problem could be fixed as our system is 40 years old but to my surprise, GMP Septic did not disappoint. I am extremely happy with the work that was done and customer service was top notch. Gary was very easy to communicate with and was available to answer all our questions throughout the process. The price quoted was very reasonable and I think they saved us a lot of money by fixing the issue instead of having to replace the whole system. I highly recommend GMP Septic & Sewer and will definitely use their services again!
