Patriot was established by four industry leaders with over 50 years of collective experience. Drawing from extensive collaboration with major home improvement corporations, we developed a strategic vision that culminated in the formation of Patriot. Our motivation stemmed from identifying inefficiencies within prominent home improvement firms and their impact on everyday consumers. At Patriot, our mission is rooted in a commitment to serve the community.

"Patriot Bath Remodeling (PBR) provided excellent craftsmanship, excellent quality of materials, and excellent communications for my bathroom remodel. I had a very small, dingy, claustrophobic shower (32" x32") in a very cramped bathroom (6' x 6') that was in desperate need of replacement. PBR took the time to understand my needs and the restrictions of the room and transformed the area. PBR coordinated all details of the project from getting permits, to delivery of materials, and to scheduling the plumbers, floor installers, and electrician. Every workman was talented, courteous and professional; best of all they showed upon time and made every effort to minimize the unavoidable mess caused by remodeling in a very old house. I HIGHLY recommend these folks!!! You won’t regret it!! "

Water Heaters questions, answered by experts

The time it takes to replace a water heater depends on the complexity of the job. Expect your contractor to spend:

  • One to three hours on a standard tank-style water heater replacement

  • Two to three hours on a tankless water heater replacement

  • Four to six hours replacing a tank-style water heater with a tankless water heater

  • One hour for each additional parallel or point-of-use water heater

Your project will take longer if you’re switching fuel sources, upgrading to tankless, or relocating your water heater.

It usually takes a professional water heater installer between two and three hours to remove an existing water heater and install a new tank heater. However, it could take four to five hours if they have to work in a small utility closet or another tight area, like a crawl space. Tankless water heaters have a more complicated installation process, so they will take a bit longer. Additionally, a gas water heater requires a connection to a gas line, and that alone can add about an hour to the installation timeline compared to installing an electric water heater.

The right way to vent a gas water heater is to have a pipe directly upward or slopes upward out of the house. Because hot air naturally rises, this type of venting will efficiently ensure that all gas moves out of the house. Your system may rely on fans or blowers as well.

The lifespan of your water heater depends on the type of water. For traditional water heaters, you can expect it to last between 8 and 12 years if gas or 10 to 15 years if electric. Tankless water heaters can last up to 20 years with proper maintenance. The total number of years you’ll get out of your water heater depends on the maintenance it receives and how much it’s used.

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.
