"I hired this company to extend the natural gas in my house and would definitely recommend them. I felt that the plumber who did the installation really knew what he was doing and seemed like a great guy. The installation went well and the price was fair."

"John has always been about the most polite and professional contractor we have used, and has been our go-to guy for several years now. From installing a water softener to fixing old piping to/from the upstairs bath to installing a toilet (which I couldn't do since I've never sweated copper piping, which this required). Prices are fair, and the jobs are not done until he's sure they are. Will definitely continue using his services. Highly recommended."

Water Softeners FAQs, answered by experts

Softened water prevents scale deposits, reducing appliance wear, leading to energy savings and longer-lasting household fixtures.

It’s not a good idea to oversize your water softener. Doing so will mean the tank doesn’t get full, which can lead to channeling. This leads to a large portion of the resin beads not being utilized and the beads at the bottom of the tank being overused. Over time, this will reduce the efficiency of your system, not to mention that the upfront cost of an oversized softener is unnecessarily high. If you have a timed regeneration cycle rather than a demand-based one, you’ll also spend far more on replacing salt than you need to.

Whether you need a permit or license for a water softener installation depends on your location, as requirements vary significantly. Some municipalities require the installer to hold a plumbing license, some mandate a permit and an inspection, and others require both. In some areas, no special permit or license is needed at all.

To determine the rules in your area, you can contact your local building department or consult a local water softener installer or plumber. Often, only certified professionals are authorized to pull the necessary permits, and they will typically handle the entire permitting process 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 Angi’s state licensing tool to check an installer’s license status.

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.

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.
