Recommended Customer Reviews

Robert ""The Boss"" and Neil from Express Water Heaters & Plumbing came to my home. They came the same day that I called them and after assessing my leaking water heater, advised it needed to be replaced. Robert took the time to explain in depth what the issue was and the cost to repair. Robert additionally explained what had caused the issue (Faulty water pressure regulator). Robert was very honest and both he and Neil were very professional. I will recomend them for all my friends plumbing needs in the future!!

I called around 11:00 and Robert and crew arrived by 2:00 with a new water heater. Robert was courteous and concise on the phone. They replaced my leaking water heater in about 2 hours. They charged me a little extra to move my washer but overall didn't nickel and dime me. Overall I am pleased with the service.

VERY pleased with the service :) My hot water service went out this week, and I had Robert ('the Boss') and Neil from Express Water Heaters & Plumbing come to my home. They came the same day that I called them, and after assessing it Robert took the time to explain in depth what the issue was and the cost to repair, and educated me to my options. I opted for a replacement rather than repair as my old system was out of warranty. He was able to have the new system ordered, delivered and installed the very next morning.
I also had issues with my 3 toilets (all of which leaked) and the kitchen tap which thumped when the hot water was on. A previous plumber had told me I needed a replacement kitchen tap because a part inside it had worn out. I had purchased a new one from Home Depot and asked Robert to install it for me while he was here, and take a look at the toilets. He fixed all three toilets on the first day he was here, and after taking a look at the tap found the issue was a valve allowing air in, made some adjustments and fixed the issue in seconds (at no charge). I just saved myself $200 on the tap replacement which I am taking back to Home Depot for a refund!!!
On the second day while installing my water heater my cat got out (not to do with him). But I was outside looking for her, and Robert and Neil offered to help me and once they had finished the job they walked around the block looking for her. If that is not great service I don't know what is!!
Also Robert offered me the ability to pay via credit card through PayPal without charging additional fees which I was really pleased with, as you don't always get this service these days. He also gave me the $25 off Yelp offer on both days he was here, so I saved another $50.
They were very friendly, personable, knowledgeable, efficient and helpful and the service really was outstanding. I highly recommend them and will certainly use them again for any of my future plumbing needs, very very happy :)

This man was rude, angry, and unhelpful. I am not sure why he is even in business. When I called my husband and he spoke with my husband he created a softer, nicer tone. But he acted as if he didn't like women and was angry to even be doing our installation. I would never use this man ever again based on the way he treated me as a customer. I bought 3 toilets from Pacific Sales, but I will buy nothing from them again if he is the installer because I would never allow him into our home to install anything.

I am very very pleased with the service I received from Express Water Heaters. Robert was on time, very professional and did an excellent job. Both he and his associate were very polite and thorough in explaining all that was being done and why. I have used other companies in the past but will only use Express Water Heaters from now on. Great service, thanks Robert!!!

Great job and they do it right! Came home Tuesday afternoon to my water heater leaking. Robert and company had installed a new water heater and were out of here less than 2 1/2 hours from when I made the initial service call. One more thing, $price was just as we discussed on the phone. Highly recommended!

Yet another 5-star review for these guys. On my suggestion, my elder son hired them for a shutoff valve (3), water heater, and pressure regulator replacement job. My sons and I are proficient do-it-yourselfers, but every truly successful DIYer knows when to ask for help. Robert delivers what he promises, when he promises, at the price he promises, and he and his associate definitely know their trade. You can't go wrong with them.

Wow! I had water leak in water heater that soaked the surrounding drywall in my garage. I got a quote of $1269 for new water heater with install. They also wanted to have another company come out to repair drywall and charge me another $450 to reinstall water heater once they were done. Robert came out and for $931 replaced the water heater and all its surrounding parts, reinforced the platform with steel stand, I am currently drying the barely wet drywall with a fan. What a deal and I got a good brand water heater and service being on time and done in a timely manner. Next I am going to have him install a new toilet for $175 flat rate. Yepee!

I was very happy with this company and would use them again. My water heater is located in the house and the staff took extra care to protect my hardwood floors. Installing in a home was $100 extra, but I was notified before they came out so no surprises. They arrived on time. They replaced all attachments to the water heater including: venting, new drip pan, reattached the earthquake strap, cleaned up the area and recycled the old water heater all for the same price listed on the website. Good Job!

Robert squeezed me in at the last minute and installed our new water heater in about 2 hours... works great, clean install, and very nice and professional installers!
