I met Mr. Gary from GM Plumbing ,when I was selling a house to my client in Rancho Palos Verdes. He did the inspection for the buyer and also installed the septic tank for the seller. There was a deadline and Mr. Gary was able to get all permits and installed the septic tank on time.

Gary and his team worked very hard on the first project we had, and we were so impressed we hired them for a second job. Overall, we had a great experience and would highly recommend them.

Don’t waste your time with anyone else. Call Gary and his staff. We had a 9 yr old sewage mascerator pump that died. I had several quotes that were absolutely outrageous- way more than it cost to install the whole system! Gary took my call, worked with us to make sure we had all the correct parts, showed up on time and knocked out the job perfectly and well within budget. His crew is kind and skilled. They kept the work space neat and worked skillfully. These guys deserve your business. Don’t hesitate to call them. We have done decades worth of renovations- much of the work ourselves. I’ve dealt with all kinds of contractors and these guys are great!
