"In the process of buying a home, we had Tony’s to give an estimate on the inspection report items found. Even though he was busy he arranged his time to fit it into his day. His quote was reasonable. After buying the house we hired Tony’s to do the inspection repairs and was able to get an appt quickly. Chris and Winston were very nice and professional. It took longer to complete the job but that happens. On one of the days they were to come back to work, we had appts at the DMV so I arranged for Chris to drive over and pick up the house key so they could work while we were stuck waiting. The work they did passed the city’s inspection as well. Just as Chris and Winston were finishing up the job, the pilot light go out on the water heater. Thankfully the tank was still under warranty so the part was free. Once the part came in Paul was able to install it that day, which was a Fri so we would have hot water over the weekend. Mandie, Angie and Karen were a huge help during the whole process and are all very nice. I truly appreciated their patience with working with me through it all! We are also working with Tony’s to have the sewer pipe repaired and my interaction with John, who is their pro for this type of work has been super nice and patient while explaining things to me and answering my questions on the subject. This repair is still in the strategic stage as the city is involved but I have no doubts in John’s ability to fix the repairs. We also are immensely appreciative in his efforts working with the city! I definitely recommend Tony’s! They will be our plumber for as long as we live here!"

"Unfortunately there was a defective fitting that caused a pipe to burst. The house was vacant so we didn't learn about it until the next day. Alvin bent over backwards to repaire the damage, replace the ruined water heater, and make us whole. He even changed the water heater to a tankless model because the location of the ruined water heater didn't meet code and tankless was our only option."

"Thank you to Geremi and GMC plumbing for all your hard work. They replaced all my pipes, my tub, toilets, faucets and fixtures, my hot water heater and the casing that houses it and they re-dug the sewer line. All this for a very reasonable price and they could not have been any more courteous and professional. Highly recommend this licensed plumber for any project that you have."

"I had Glover Plumbing Solutions replace my old yucky tub with a Delta rainforest Walkin Shower, as well as my old tank water heater with a Navien 240A2 tankless water heater and recirculation system. Ryan did a great job with the installation and made sure everything met California code requirements. The workmanship was excellent, everything was tested before he left. Im beyond thrilled he gave me the bathroom of my dreams and im hard to please. I seriously recommend this young man."

"Great service and work from Miguel and team. I would hire them again. What originally was a slow draining sewer line turned into a root infested backup. Miguel was able to scope the drain and visualize the root of the problem. They were prepared to start digging and had the tools and supplies on the truck to get the job completed. He clearly explained the discovery, repair, and installation process as well as potential other root intrusion spots. After the dig, the soil and grass was replaced and can hardly tell that any work was done. They also cleaned the dirt/mud on the concrete walk way. Thank you Miguel and team for the great work."

"Tony was good mostly. Pros: He was on time every time. This is big for contractors. He was on time for estimates and both times he had to come to place He was the best priced The water heater is installed and working. Cons: His quote was very vague. He told me he would put plywood and install a replacement water heater. And he did. However, the first time he installed was with OSD board...basically looked like junkyard plywood that they put underneath water heater... not good and it was inside my house, maybe if this was in a garage you could get away with it, buy my water heater is in my closet. The first time they came out they installed the wrong water heater, claiming mixup at the warehouse. I can not confirm or validate this, but they did come back the next day with the correct size and also replaced the particle board stuff with real solid plywood that he put a layer of paint on. Once the discovery of the error with the wrong water heater and the bad wood. Communication got very short. He agreed to get replaced then hung up on me. We ended up texting and I offered to pay a bit extra for higher quality material, I just asked that he let me know what that cost would be. He never told me what the new cost would be until the job was completed and I was given the bill. Overall: All in all, he is very well priced, his people were on time and professional, and he did what he said he would do, so he is an honest contractor which is good. My experience was not the best but I would give him a call again however would request a more detailed quote."

"I had another plumber install a line for an ice maker about a year ago.  Told him it needed an T-Valve, not a saddle valve, as noted in the refrigerator manual (and later to find out L.A. Building Code requirements).Well, he didn't and the ice maker broke.  Sears said before they would fix it, the line needed to be fixed, and there was no talking to the original plumber.That's where Plotke came in.  The plumber (Danial) arrived on-time and was polite and professional.He told me that the work done was also not in code (see above) and got right to work. Now I have a working ice maker.  No more buying ice from the market."
