I contacted Robert Johnson to replace the water heater in my home. We discussed the tasks involved and came to an agreement. He showed up the next day and completed the job within a few hours. I was very impressed with his professionalism and quality of his work. I found the price to be very reasonable and would highly recommend him to my friends and family.

If you are seeking a professional plumber and outstanding individual to replace a hot water heater look no further. Robert was everything I was looking for to address my needs. Robert was exceptional at addressing all of my questions and concerns. His communication was outstanding and he was punctual the day of the installation. Robert quoted a fair price for his services and did exactly what he said he would do. Upon completion of the installation , he left the work space in better condition than when he started. Can’t thank him enough. Robert exceeded my expectations. Job well done and grateful!

Great pro. Put in hot water tank. Neat and perfect. Done in 2 hrs. as stated before starting the job. Loved having chosen Robert for the job. Very efficient and arrived on time. The space was small and he had no problems. Don’t hesitate to call Robert Johnson to replace your hot water tank. We are very pleased. Thank You

Best price of 6 quotes. But more importantly, did a great job and worked with my 90 year old mom home alone that has hearing and vision difficulty. He sent pics and everything. 6 STARS!

My water heater tank was leaking. I called Robert and he came within minutes ( literally). He gave a free evaluation and quoted a very reasonable price to replace the water heater and remove the old unit. He came the next morning and completed the job by noon. Robert did an excellent job. I highly recommend him for your plumbing service needs. Especially water heaters….

Replacement of hot water tank. I wasn't able to do the job right away because of my schedule, Robert guided me and reached out several times to see if anything changed during the process. Once he was able to complete the project, he even showed me how to maintain the tank. What a great job.
