All your plumbing needs with one company

"Gold Star Plumbing provided excellent service and, most importantly, stood by their work. Although there was an issue after the initial installation, they responded with professionalism and took full responsibility. They didn’t make excuses or try to avoid the situation—they came back, listened to my concerns, and took the time to thoroughly investigate and address the problem. In today’s world, it’s rare to find companies that not only do the job but also stand behind it when something goes wrong. Their commitment to follow-through and customer satisfaction really stood out to me. Thanks to their honesty, accountability, and respectful communication, I now feel confident that the work was done right. I highly recommend Gold Star Plumbing to anyone looking for reliable and trustworthy service."

AT Fred Oakley Construction Company, we are experienced professionals providing quality Kitchen, Bathroom and Interior Remodeling in the Hendersonville/Greater Nashville/Middle Tennessee area. We use only quality sub-contractors that cover every aspect of Construction and remodeling. Call us today at 615-975-8916 to schedule an appointment. We look forward to serving your home improvement needs. "When it comes to Quality Remodeling, WE NAIL IT!

"We have a home that was built in 1930, that is loaded with charm but needed some adapting to our family’s needs. It had two too many doors and one large window that we never used because it looked directly at the neighbor’s driveway! We also needed to have new windows and floors installed, custom bookshelves built, and of course new paint. We decided to hire Fred because from Day One you could tell he was someone that was knowledgable and someone you can trust. Having someone you can trust to do projects in your home is so important because they become a part of your lives for at least a month or so! Fred took care of everything: the supples, installation, paint, and making sure that the brick installers completed the job successfully as well. I now have an office that used to be an “all weather” porch that I can actually be in all day, another office/second bedroom that has more wall space thanks to the seamless work Fred did in closing up a large window and door (not to mention it was with plaster!) He was really precise in doing “delicate demo” since we were trying to save as much of the old house charm as possible. We were even able to use one of the doors in my new office, and it looks beautiful. Cost wise, everything was up front and there were no surprises (even though he was very gracious about us adding items along the way (like extra plugs and installing a storm door). We also had our attic re-insulated and part of our floor lifted which Fred took care of as well. He communicated with us every step along the way, which is also so important. We hope to have a custom closet installed in the near future and will definitely call Fred to do that project as well! 10/10 recommend Fred Oakley for your home renovations!"

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
