"Everything looks good after the work was done. I can finally close my bathroom door. I appreciated the fact that the foreman Erick Baez, went over what was done as they were done. I also appreciated that the two installers Manny Erickson and Jesus Villagomez also communicated with me after they were done to reassure that they did a proper job installing the jacks. Very good to know how the process was going. Great job."

"After lining up three plumbing contractors to install a kitchen faucet, a garbage disposal and fix a drainage leak, I selected Superior Plumbing to do the job because their technician seemed to have the necessary professionalism for a good job and they were also the least expensive of the three contractors I contacted. My service tech Armin was on time, cheerful, courteous and knowledgeable. It was obvious that he cared for my particular needs and he even announced that he loves his job and always looks forward to doing things right. He took almost exactly the time that was originally quoted and did an excellent job, cleaning up thoroughly before leaving. I wouldn't hesitate to use their services again. Thanks Armin."

"I am re-landscaping my yard and had used Nato before for a small project and he did a good job for me so I asked him to bid this project. His price was competitive. He and his crew arrived promptly, completed the job on time and did quality work. I installed some irrigation lines and landscape lighting conduit during their job and I was pretty slow and it delayed them from filling in their trenches. Nato and his crew were very patient and Nato actually helped me at one point since I was such rookie. My landscape architect wanted the drains to be done a certain way and while it was not the usual way Nato did drains he was fine doing it the way that was requested. I would definitely use him again and told him to use me as a reference."

"I had a trenchless sewer line replacement done on my property. I got a great price for all of the work they did and incredible customer support. They repaired everything as though they were never there. I had a great experience working with Platinum General Engineering & Construction. They handled everything from start to finish without me having to deal with the city or other headaches. I highly recommend them!"

"Came earlier than anticipated. Cleared toilet promptly after 2 tries. Took approximately 10 minutes. Removed stain at bottom of toilet bowl caused by implement used, and showed me how to remove water and refill if it needs to be cleaned in future. Discussed possible future installation of hot water heater. Very personable and professional, as was owner when I made initial contact this AM."

"I used this company before and had a great experience. I was looking for a company that did re-piping and not only did they do a great job before but they came in lowest bid. They were always on time when starting. Raul was there with his crew which were all great. They re-piped the whole mobile home which is 680 sq. ft. They put in connectors for water and new gas lines for stove, gas dryer, washing machine, dishwasher, ice maker and clean out. They moved the existing gas line over to new area in kitchen and added a new gas line for the dryer which will by next to the kitchen along with new piping that didn't exist like washing machine, dishwasher and ice maker. They moved the piping for sink area to another area of the kitchen. This whole process took a few days but it was worth it because they were very reliable and honest and their price came in lower then other companies. Raul, you are the man!
