"Very professional. Matt was great! Explained exactly what he recommended and listened to me as well. He was very prompt to get the situation resolved. He cleaned up after he was done. I would most definitely reach back to him for any future plumbing projects."

"They came and gave me a quote of 4500, I needed the job done so I hired them They sent another company to suck the tank out and they discovered that my tolites was running water they had some suggestions well I repair them and that fixed my problem then the guys from superior came and run the pressure washer and the job wound up costing me 5144 and in advance I told them I was on disability and fixed income, I highly recommend looking around before taking with these guys I know I feel like I was taken advantage of, they will never do any business for me again, another company found the problem and told me how to fix it, I fixed it, and superior made the money for it to me this is a big ripoff"
