I highly advise anyone who comes across this review to avoid this man and his company at all costs. I am astounded at the lack of professionalism that I experienced working with Kelly Walters. I have also attached images of all written documentation of my below experience. I originally texted his company on October 6th. Within the hour, Kelly called me personally and asked what issues we were experiencing. He let me know he would speak with me soon, but would potentially come out that day to take a look. After no follow up on the 6th, I sent another text message on October 7th, asking if he was still able to help us out and that there was no urgency. He said he was working on the schedule for the next week and he had not forgotten about us. October 13th, I sent him another text and he responded letting me know he would call that day to get us on the calendar. October 16th, I sent another text. He responded and asked where we were located, then asked if he could come out and diagnosis it that day (which was a Saturday). He arrived at our house and spent quite a bit of time explaining our system to my husband and diagnosing the problem, which was that we needed a filter replaced and some tubing replaced for a chlorine system we have. While he was here, he was very professional, kind, and easy to talk to. He apologized multiple times for the delay and got everything back in order again, letting us know that he would send his technician out later that week if we had not replaced the filter yet. As he was leaving, my husband asked him what we owed and he said nothing, he said that if we did additional work, it would be included in the total there but there was no charge for the day. Later the following week, he called to let me know that he found that we had higher levels of manganese in our water, which can be dangerous since we have small children. He also had his technician replace our filter and tubing, which was completed. Our total was $432.00, which we paid with no hesitation. I personally prefer to have documentation when work is completed on my home, for my own records and in case I need to provide it for a future sale. The invoice that I was emailed, under charges, just listed $432.00 with the word ‘Fix’. This does not describe any of the parts, labor, or service charges. I decided to email Kelly, asking if he could itemize the invoice for me. The email ([*** Link removed ***] that I received in response was one of the most insulting, rude, and unprofessional emails I have ever been sent. Clearly, me asking for clarity was extremely offensive to him and he made sure I was aware of this. While he provided a rough invoice, he listed his service call fee as $300. This was not something we discussed at any point, nor is it currently (as of 10/23/2021) listed on his website. As I stated previously, he told my husband no charge initially. In regards to the water test, he offered to do it while he was here, and did not indicate any dollar value at that time. Had I been made aware of a $750 water test, I would have politely declined. Simply put, until his “itemization” he was not upfront about any of his charges. He also threatened to withhold the water testing results, due to the “additional overhead charges for itemizing extremely minor and low-priced maintenance services”, despite letting us know how dangerous manganese can be in a home water supply when there are children in the home. In his email, I would also like to point out that he made it clear that him coming on a Saturday was a major sacrifice. He asked to come out on a weekend. I did not push for this. He also, in many other reviews that are posted on various sites, will see that weekend visits are not an uncommon occurrence in his business. This situation is a clear example of how a 5-star business becomes a 1-star business, over a simple choice to email a paying client with such blatant disrespect. I would never work with someone who is this easily unhinged in his ability to maintain appropriate discourse and respect to those who trust his work.
