"Great. The contractor from Jimmy Gusky arrived on time and within 45 minutes had provided a full inspection and determined the unit was fine and had simply malfunctioned temporarily during several extremely hot day.s. So this saved me many thousands of dollars. Great experience."

"It went amazing. Paid the extra bucks for emergency service, because of our smallish waterfall, looking leak, sprouting from a bathroom pipe, enough to puddle water onto our basement/laundry room floor. Initially, spoke to Chris, who was pleasant and upfront with the per hour fees, for emergency services. He sent us Tim, who was hesitant at first, due to the location of the leak, but his experience and knowledge, enabled him to decipher the location of our leak and fix it. A quick trip to Lowes, where he promptly returned and in 90 minutes, the job was done. A week later and the valve is bone dry. Yay!!!"

"This was a low complexity modification to a existing gas line connecting to a gas range. It took approximately an hour with two staff. One thing I was concerned about was the usage of a lighter to check for gas leaks. Typically this type of checking is done using soapy water as using fire to check for gas leaks can be hazardous."

"Josh and his crew were professional, on time and explained the install throughly. Josh installed a wall charger for my electric vehicle, disconnect shut off switch in the garage, ran cabling from a new 60amp circuit, additional receptacles in the garage I asked for, whole house surge protector, and more. It was a big job! The best part is my kids were still able to distance learn in the bedrooms without interruption of power while install occurred. Josh answered questions I had even after the job was complete over his personal cell phone when I followed up with a call. This makes for great customer service! Iâ ll definitely be using Wenbrooke for more services in the future. Nice work gentlemen!"

Water Heaters FAQs, answered by experts

Gas water heaters last between eight and 12 years on average. You can help them reach their maximum lifespan with regular cleanings, maintenance, and professional checkups, though don’t hesitate to swing for a full replacement if the total cost of repairs is greater than that of purchasing and installing a new unit. 

No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing.

On average, a tankless water heater should last between 10 and 15 years. Its lifespan will be affected by how much it's used, the effect of weather where your home is on the unit—colder is harsher and will shorten lifespan—and if the heater is maintained appropriately and regularly. There are many signs your water heater needs to be replaced, so pay attention to anything that changes with your heater or hot water.

If your water heater is about to celebrate the big 2-0, you may want to consider sending it off to greener pastures. While the water heater may seem to be working well, any conventional, tanked water heater over 10 years of age is at risk of failure. If your water heater is 20 years or older, your best move is to replace your aging heater before it completely breaks down.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.
