"More than exceeded my expectations. Very professional in every way from cleanliness to respectfulness. Needed a new water heater installed. Other companies wanted an arm and a leg while hermoso plumbing gave me a great deal with even greater service. In and out faster than expected with no hassles. Will definitely be giving them a call back for all my plumbing needs. Highly recommended."

"I called Water Heaters Only out of desperation on Sunday...Seth @ toll free # was fully aware of our tenants being without hot water for 2 days and was able to get a technician out on Monday morning. Monday @ 5 pm, hot water was up and running. David, the technician knew what had to be done to get the heater up and running. The next day, we did have a hiccup with a part but David came out immediately and tweaked the part -- all is good. Here is what I like -- 1. no sales pitch. 2. David gave me a plan b for possible additional work. 3. this company is available 365 days and you dont have to wait for parts to be delivered from out of state. 4. Water Heaters Only has their own facility for parts."

"The whole process was very smooth. They came out and spent a couple of hours assessing the problems...turns out we had several. The water heater burner had failed and was under warranty. But they also discovered our pressure regulator had failed, our gate valve was frozen, and we had a pipe leaking in the wall! They found the necessary part for the warranty repair and drove 50 miles each way to get it rather than make us wait 1-2 days for for the part to be shipped. They stayed until all the problems were resolved which was greatly appreciated! (My wife and three daughters were not relishing cold showers!)"

"Generally, it went well. I was told exactly what they were going to do before they did the work. The first day, I was taken aback at the price of the work, I assumed the original request would not be such an ordeal, so they allowed me time to consider the work and price while they fixed the toilet. I did decide to go ahead with Top Contender, and I am glad I did. They opened up the wall opposite the faucet, shower head, etc, and found rotten wood, which they replaced, cut away old pipes that were causing electrolysis, reinforced the pipes with staples(not sure of the technical terms), and patched up their work after replacing the shower head, faucet and spout. They were thorough. I had to add additional work to the kitchen faucet problem after cleaning under the sink and notice a crack on the pipe and ask if they would replace it after they fixed the faucet. The issue with the faucet was that it looked like it should have been stuck in the wall a lot further. I wanted to add tile on the wall behind the sink and the faucet stuck out of the wall. The exposed section was covered nicely and I am able to slide the piece, install the tile, and slide the piece back to the wall - problem solved. They did remove the plumbing underneath the sink with new, ABS p-trap assembly. Before they worked in the bathroom, they papered the floor from the front door through the bathroom, used any parts I had on hand, and aired out the bathroom during the entire time. They did clean up, better than most.. not perfect (but I would only notice that).."

"Evening of Valentine's Day we learned our water heater had broken.
Called Bob & Marc the next morning and had an appointment of 3 pm. They were available earlier, but I could not get out of work any earlier.
Spencer was on time and got right to work. He was very professional, careful and friendly.
He assessed that the water heater was broken, drained and removed the old one and installed the new one.
He made sure that the TPM piping was exact, fit and would last. He was very helpful in explaining what he was doing and was even very helpful in providing advice on how to extend the life of this new water heater.
He cleaned up and all that was left was a professionally installed water heater that has been working great.
Thanks for the quick, friendly service (also be sure to use the 10% off coupon found on their  Angie's list page).
