"Will Melendez visited our home and confirmed an independent lab finding of hard water. He listened to our concerns and outlined options to address them. Once we decided which option to pursue, he set a date for system installation and associated electrical work, which provided by an independent licensed electrician. Nick, the installer, arrived on time and worked a full day to implement the system. His work was neat and professional. I had 3 other contractors in - all of whom received good grades on Angies List - before selecting Culligan. They had the most competitive price and provided the most comprehensive solution."

Water Softeners questions, answered by experts

Whether or not your water softener installation requires a permit depends on where you live; some municipalities only let certified plumbers and electricians pull the necessary permits and complete the work, others only require a professional to sign off on the work, and some don’t mandate permits at all. You can contact your local building department to find out, but you can also ask a local water softener installer or plumber to see if a permit is necessary. They will usually pull the permits for you and can help close them out after the work is complete.

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.

Hard water stains can be a headache because they will reoccur as long as hard water flows through. Thankfully, hard water stains are not permanent. With the right tools and an appropriate cleaning routine, you can prevent hard water stains from ever building up. However, you might feel like you are stuck in a constant cleaning cycle. In that case, you may consider hiring a contractor to perform routine cleaning.

Replacing a water softener costs $200 to $6,000, depending on the capacity of the water softener, the type of water softener, and the amount of people living in your home. An ion exchange water softener is the most common type and costs $500 to $3,000. Water distillers, which cost $1,200 to $4,000, and dual-tank models, which cost $1,000 to $5,000, are definitely pricey, but they offer more filtration or capacity, respectively.

No, a water descaler won't descale pipes. The charged water running through the pipes may very slowly dissolve mineral deposits and hold them inside the water, but it's a very gradual process. If your pipes do need descaling, it's much better to get a local plumber to descale your pipes.
