"We were having so many issues with flooding and hard water. H20 Care came in found the issues and fixed them. We have not had any flooding issues since. We also decided to have a Reverse Osmosis System installed on our Well and let me tell you "BEST DECISION EVER" no more hard water, our skin is softer, the drinking water is crisp, clear and even tastes better. I can't thank them enough! Water issues, the only number you need is to H20 Care Inc! 5STARS"
Whole House Reverse Osmosis Desalination System
High efficiency water softener with sediment and carbon filtration to correct hard water, manganese and sediment build-up as well as chlorine taste & odor on this public water supply.
The water from this private well revealed high radon and iron in the lab water test.  This system eliminated these water quality issues.

"I am very happy with the work that was done by their team. They even helped with a small related issue that wasn't part of the original contract free of charge. I would recommend them for water filter and softener installation."

"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!"

"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 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."

Water Softeners questions, answered by experts

Whether you need a license or permit for water softener installation depends on your location. Some municipalities require the installer to hold a plumbing license, while others may only require a permit and an inspection. In some cases, both a permit and a licensed installer are necessary, and some areas have no requirements at all. Often, only certified plumbers and electricians are allowed to pull the necessary permits. To find out the specific regulations in your area, you can contact your local building department. Alternatively, a local water softener installer or plumber will be familiar with the requirements and can typically pull the permits for you. Regardless of local laws, it is always recommended to hire a licensed professional to ensure the system is sized and installed correctly. You can use tools like Angi’s state licensing tool to verify an installer's license status.

The average cost to install a water softener, including the system and labor, is approximately $1,500. However, the total price can range widely from $600 to $6,000. For some complete systems, the cost may be between $800 and $2,500. Labor for the installation typically costs between $150 and $1,000.

The final price is influenced by several factors, including:

  • System type, capacity, and complexity

  • Home size and household water demands

  • Water hardness levels

  • Accessibility of the installation site and the extent of plumbing work required

  • Whether new electrical work is needed

  • The professional hired and any local permit costs

Yes, a water softener can remove scale deposits. According to the U.S. Department of Energy, after you add a water softener to your home, “gradually the softer water will dissolve limescale scale deposits and remove the problem entirely.” Installing a water softener—or water descaler—will also help prevent new scale deposits from forming.

A lower-end water softener would cost around $900, not including installation. Each home has different requirements, water hardness, and number of inhabitants, so there’s a huge range in pricing—$600 to over $6,000. The average water softener repair bill is around $500, meaning it’s a much better option to repair any issues and only replace your softener if absolutely necessary. 

Yes. Hard water is what causes scale buildup, and a whole-house filter provides numerous benefits beyond water softening. Any water that enters your home will go through the filter, which cleans up all water that you will use for cooking, bathing, and drinking. A whole-house water filter also blocks harmful particles like heavy metals.
