"Bruce really listened to how I answered his questions and designed a natural-gas fueled steam boiler system that met all the requirements with the expansion potential I requested. During pre-installation logistics and the day of installation, Bruce and his crew were on-time, courteous and professional. Their work demonstrated the benefits of hiring a fully credentialed company, skilled and experienced at their craft. They completed their work in one very long day so that I could avoid a night without heat during a stretch of very cold January days. I trust Williams & Assoc. and would hire them for additional work in my home as needed"

"Service was performed on time while meeting my expectations. The plumber (Felipe) was very professional and answered my questions before and during the process. No mess, all cleaned at completion with a very good looking new hot water heater. All in all we are very satisfied. Yes, I would definitely use again. Highly recommend."

"We needed to replace a patch of our living room ceiling due to damage from a water leak upstairs. We contacted C&B, who responded and quoted us a price quickly. The price was fair for a multi-day job, they got it done within a week, and they even helped us repaint the ceiling. Very professional, courteous, and trustworthy. We'd strongly recommend!"

Water Heaters FAQs, answered by experts

The average cost to replace a water heater is around $1,325, with a typical range of $900 to $1,800 for a standard replacement. The final price depends on the type of heater (tank vs. tankless), its size, fuel source (gas or electric), and the complexity of the installation. A simple one-to-one replacement will be on the lower end of the cost spectrum. However, if you are switching from one type of heater or energy source to another, you can expect labor costs to be significantly higher due to the extra work involved. It's also worth considering that while gas and electric heaters may have similar upfront costs, their long-term operating costs can differ based on local utility prices.

The average water heater holds between 40 and 60 gallons, but the exact amount of water that comes out during draining will depend on your unit’s capacity. The amount of time it takes to drain a water heater averages from 10 to 30 minutes.

When replacing an old unit, you might want to switch from a gas water heater to an electric water heater or vice versa. To do this, you will likely need to add infrastructure to the area. For example, you likely don’t have a gas line that served your old electric water heater. You’d have to call a plumber to put in a new gas line. If you’re replacing a gas unit with an electric one, the plumber will need to safely cap the old gas line. You will then need an electrician to add wiring for the new electric unit.

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.

Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.
