"Fantastic communication, for both the assessment appt and the installation. Right on time, quick and efficient, whole install took about an hour, and left the area cleaner than when they arrived. 10/10 for this company"

"Excellent job replacing under cabinet lights."

"Secondwind Water Systems was excellent from start to finish. The process began about three months ago with Jesse, a Certified Water Specialist, who thoroughly tested our water and designed a comprehensive system. He was patient, informative, and never pushy while I took time to decide. Installation was completed this past Monday and included sediment filtration, a water softener, radon and PFAS removal, and reverse osmosis to our drinking water and refrigerator ice maker. Patrick, the senior technician, and his assistant Ronald were professional, knowledgeable, and did a very clean, well-organized basement install. Patrick took the time to explain how the system works and what maintenance is required. Christine in the office was friendly and extremely helpful with payment and organizing all documentation needed for state reimbursement related to the PFAS system. Highly recommend Secondwind Water Systems for quality work and excellent customer service."

"They were fantastic, would use them again."

"Installed water filtration system and softener, was very helpful and explained everything clearly with transparent pricing."

"Install was scheduled for 9:30 EST 12/22/2025. At approx10:30am called to inquire as to his status. He told me he was 10 mins away. He arrived an hour later. He was somewhat agitated on arrival. We together unboxed the new faucet and he examined the existing functional kitchen faucet. The system in place was result of new construction in 2017.He raised no concerns about new product quality or concerns about getting the job done. He was at the job approx. 2 hours and I was present close by throughout. After approx. one hour he became more and more agitated. He asked me to show him the basement as he "needed more length" to hook up the product. No changes took place in the basement. Shortly thereafter he announced the new product was "cheap" and suddenly "fell apart". He became agitated and told me the only option was to return the product and that he now had to replace the previous existing faucet. At this time on my exam noted one of the water hoses on the new product was no longer functional. There was a short extension on the other hose which I commented seemed to imply he had realized the new product hoses were too short. He quickly took off that extension and put it in his pocket, reiterated the new product was "junk". When done he asked me for 500$ for the two hours work and left. On my further exam of the new faucet after he left was clear he had been trying to stretch these short hoses to the point of damaging beyond repair both (please see pics) hoses. It was obvious all of this could have been avoided by adding extensions from the start. The under sink area would have easily accommodated this. In retrospect I am sorry I paid him. But, I am elderly, live on a rural dead end dirt road and just needed him out of the house. It is why I use a company like Angi to hopefully have some screening responsibility. Follow up communication has been difficult during the holidays. Ultimately I did speak with him. He continued to be dismissive and challenged me to seek legal recourse. I questioned his agitation that day. I asked if he had been drinking (both my parents were heavy drinkers and I regret not following that suspicion that day). He did not deny just replying "If you are so smart why didn't you do the job yourself". I told him that is why I strive to employ reputable contractors, always."
