Husen (Sam) was unbelievably helpful and really saved our bacon. We had a leak in the water valve behind our washing machine that prevented a new one from being delivered. We needed fast service and he came same day diagnosed that it was simply a broken valve handle and went out to a plumbing supply store to order a replacement. We always get 2 opinions on all our work and a 2nd plumber came and told us the whole valve needed to be replaced for over $1000 worth of work. This was obviously false so Sam saved us nearly $800 overall. I would highly recommend his honest and fast work.Posted on Google![]()

Had an emergency repair needed, my gardener cut my gas line by mistake. Understandably I was very concerned, I called a number of plumbers and was unsatisfied with all of their responses until I called Husen. He showed up right away, gave me a clear quote, and got the job done in less than 2 hours. He calmly walked me through the process, clearly outlined the work I needed and what I didn’t need. I will be adding Hi-Tech Plumbing to my list of trusted businesses. I wholeheartedly would recommend Hi-Tech to anyone looking for a trusted and honest plumbing professional.Posted on Google![]()

HiTech plumbing are truly lifesavers. This is a second time we are rescued by their technicians due to a leak in toilets. On each occasion they dispatched the tech promptly, quickly identified and fixed the problem. No pushy tactics, very professional, and their work van alone deserves 10 stars - always organized and has literally every part you might ever need. Company itself has very personable approach to customers, which is hard to find nowadays. Totally recommended service!Posted on Google![]()

Sam (Hi-Tech Plumbing) came to the rescue!… Very responsive (unlike other contractors) and personable. He assessed the situation and answered all our questions. Let me tell you, I had lots of questions…. Sam, thank you for your patience! I could tell he was experienced and an expert in the trade. Sam kept me abreast of all that took place to ensure I understood the process of replacing piping and valves. I could literally feel my anxiety subsiding while he worked to correct all our issues. And he’s very reasonable and affordable (unlike another contractor). We hope not to have a need for a plumber in the future, but if so…. Hi-Tech is at the top of our list.Posted on Google![]()

These gentlemen worked for hours in the pouring rain, just so that we were not out of hot water. It was a desperate situation and these guys came through for us. I highly recommend this company.
