"Chris Cash and his assistant Hunter replaced my underground water service line on 10/27/25. Both were a pleasure to work with and I wouldn’t hesitate to recommend them both for all of your plumbing needs. Chris knows how to take care of his customers and exceeded my expectations again & again!"

"My prior water heater, a 50-gallon tank, started leaking after 15 years. I called Streamline to confirm that it needed replacement, and to replace it. I was considering a tankless water heater already, and the first tech walked me through the pros and cons, then wrote up an estimate. Two additional techs came the next day to install the heater and the necessary gas and power lines. The only issue I had was that one of the newly installed gas fittings leaked gas into the basement. I shut off the supply valve and called Streamline, and they came out within half an hour to fix it at their expense. Mistakes happen, and I was impressed with how professionally they corrected that one."

"Most professional HVAC company I've ever dealt with. From estimating to installation - first class service."

"Outstanding Service from Modern Plumbing LLC! I had an excellent experience with Modern Plumbing LLC when they installed my new water heater. From start to finish, the service was professional, efficient, and stress-free. The plumber arrived on time, clearly explained my options, and walked me through the entire installation process so I knew exactly what to expect. The installation was done quickly and cleanly, with great attention to detail. Everything works perfectly, and I can already tell the quality of work is top-notch. It’s rare to find a plumbing company that combines expertise, honesty, and great customer service, but Modern Plumbing LLC absolutely delivers. I highly recommend them to anyone needing reliable plumbing or water heater installation—you won’t be disappointed!"

"Very responsive and professional. They were extremely helpful in answering all of my questions while I was researching plumbers and the best way to approach my hot water tank replacement. Given their great service and the quality of their work, I thought their pricing was competitive. I wouldn't hesitate to use them again."

"I called in the morning and Chris came out in the afternoon, when I was available. He explained and showed me what the problem was. He didn't have a new water heater on his truck so Tim came about 45 mins. to bring one. Installation was fast and Chris was very professional. They will be the first ones I call if I have any other issues."

"Only small issue was low fan speed for cooling on initial install"
