Get matched with top water treatment pros in Alton Bay, NH

"I would recommend this company 100% to anyone. My husband and I are pleased with our water treatment system. Also, Brad and Jack provided excellent customer service."

"Brian responded promptly, was professional and courteous. He came right away to do an assessment and returned within a few days to install a new water softener system. He presented me with a lower cost option that could have been done same day but I chose to replace a 17 year old system with a new system that is more accurate (better monitors water use) and less costly to operate because it uses less salt. He performed several preventative maintenance updates: re-piped and plumbed in a new particulate cartridge, cleaned the screen on the radon system and replaced the solenoids, all within the cost of what other companies quoted for only the water softener replacement. The last technician that serviced our water systems (Radon & RO) rushed through the job and left them in worse shape than they were before he "serviced" them. Brian recognized the issues and fixed them. I will now be using H20inthe603 for all of my water treatment service. Thank you Brian for a job well done!"

"Ended up just replacing my gas hot water heater. Proactive Comfort had the best price so I chose them. They explained all the options and we felt best going with them for the value."

"I had my full home repiped as I switched from electric to forced hot water heating. Fred was courteous, communicative, and timely in making the repairs. We ran into quite a few snafus and he took them in stride. His quote was MUCH lower (about half the price) of the original quote we got. Definitely recommend."

"They did a great job. Outstanding customer service. Communicated very well keeping me updated with all details and explained everything I needed to know about the system. The install went smoothly and the workmanship was very neat. When they completed the job, they cleaned up very well. I would definitely recommend them and actually have already to a friend."

"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."

"George was wonderful to work with in the planning phase, very responsive, he answered all my questions as we discussed the install. I sent him photos of where the system would go and and he confirmed it would be a good fit. He arrived promptly on the install day, along with Dave who was also great, and they put in the system. About a half hour after they left, I discovered a leak from a small copper pipe and called George. He came right back to fix it which he did, but we realized it was not his work. Someone else had put in that section of copper tubing incorrectly. George was very kind and accommodating and fixed the problem. He and Dave were a pleasure and I really appreciated it and I would absolutely hire them again."

"I thought I needed a new water softener. Justin came out and had my water tested. It ends up I don't need a softener, so it saved me a lot of money."

"Professional, experienced, and efficient installation of whole house water filter system. Very good man to work with and the system works great."
