Get matched with top water treatment pros in Dover, NH

"Installed a water treatment system quickly that turned rusty opaque water into clear water., and for a reasonable price."

"Did a great job. Also came back to install an arsenic water filter system."

"Ryan came to house and reviewed our needs and what was available. Everything was explained to us so we understood what was to be installed and what what future services we would need (filter changes and when to expect the need to change filters). The filter system was installed the next week and was done in a professional manner. We would definitely recommend them for water filtration needs."

"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!"

"Colin was very quick to contact me and get out to my home to fix my plumbing issue."

"They responded quickly to my inquiry, and were able to get someone to my home in a day to assess my boiler system"

"My only complaint was when I made the call I was not told that there was a service fee - that is not right! The guys that installed the water heater were great and left no mess - they get 5 stars â­ ï¸"

"Tech arrived on time and quickly replaced the water softener. Cleaned up afterwards and explained everything."

"George and his team did an excellent job with the install. I received quotes that were much higher for the same project and similar systems. As busy as George was he always answered my questions leading up to the install and was there right when he said he would be. George even helped me plumb a water line to my refrigerator and didn't charge me for the material he used! I have already recommended Absolute Water Systems to a friend and will certainly be using them for any future projects."

"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."
