Express Water Heaters installed my last Water heater and it lasted 14 years with not one problem - they do good work and they only use quality products. The are professional, good communicators and honest. They don't try to up-sale you. I noticed a leak last night and they came out the next day and installed a new water heater. I am a very picky client and I would highly recommend Express Water Heaters.
