"The contractor was a true pro.,he new his product ,he new how important to size the heater needed to do the job correctly and he priced the install accordingly.He was prompt always on time,removed the old water heater and made necessary changes to my home to accommodate the new tankless heater.He installed a new unit that has a great reliability history and long term warranty at a fair cost.Not heard of in todayâ s business world and the man that owns the business is the person who actually does the work! I feel like I did hire a true PRO for my job and I would recommend him to anyone that would need his service in the future!"

"I had a time slot that they were going to start which was 1:15 - 3:15pm. Rotor Rooter called about 3:15 pm asking if it was alright that they dispatched the service technician to our house which was strange since I arranged to be at home between 1:15 - 3:15 for them to start.

Once Jeff arrived, he was very professional and started immediately replacing the hot water heater. I have a 2 1/2 year old son and he did so much as to warn me that he would be making some noise. He was very easy to talk with and was able to answer all our questions. Since it was getting a little late, I suggested he could come back tomorrow to finish the toilets. He ended up doing that and came back the next day to finish both toilets. I am so glad I didn't try this myself. For him these were probably easy installs,but, he was able to know what other supplies and tools were required to complete the job correctly. I would have been lost and wasted all sorts of time.

I will call Rotor Rooter again for my plumbing needs

"RotoRooter has once again come through for me demonstrating HIGHLY Professional Customer Service. They were on time to replace a Hot Water Heater in the crawlspace. I inspected the area with them after the job was done. The quality of their work was as if it would be in a visible and high-traffic area of the kitchen where family members and guests. But this was done out of sight, in the crawlspace where only I would see it a few times a year when replacing the Whole House Filter. I am a VERY satisfied customer, and I COULD NOT BE HAPPIER WITH THEIR WORK! If you need a plumber for ANY plumbing issue that may arise in your house, I HIGHLY RECOMMEND RotoRooter!"

"Issue: water backed up in laundry room floor and downstairs bathroom commode bubbling noise when two showers were running at the same time. Anthony performed a drain vision procedure determined the possible need to replace pipes due to age, the dirt settling, small roots, grease, soap, garbage disposal, etc. A second test by Jason via drain vision for further analysis. No obstruction however, determined narrowing could continue to be an issue over time. Both Anthony and Jason are very knowledgeable."

"Murray and Sons quickly contacted me about my water heater replacement project. They were able to provide an immediate quote over the phone. They worked around my crazy schedule to get me an appointment within three days. They showed up when promised and got the job done. There were several extra things that came up which they could have easily used to raise the price above the quote but they didn't do that. The final finished installation was better than expected. And, best of all, this new water heater was installed in a way that will make it possible for me to do future replacements. I was concerned in the beginning, since they didn't have any plumbing reviews. But, their electric service reviews were excellent. I decided to give them a chance; after all, it was only a water heater. I'm glad I took the chance on them. I now have hot water again and I'm very pleased. Not many business cards make it onto my fridge but Murray and Sons Electrical is now on there."

"Andrew and his company did an amazing job with our solar system install.  They met with us, explained our options, and delivered exactly the system we were looking for.  He was always prompt, courteous, and professional.  The system looks great on our home.  The install is very clean(which was one of my wife's big concerns).  The attention to detail that they paid to our project was amazing.  They went above and beyond what was required.
I can't say yet how much electricity our system will generate since it was just installed.
I will definitely call Andrew again when I am ready to expand our system further or add Solar water heating for our pool.
