"Absolutely fantastic service!!! Jason did an amazing job installing our new tankless water heater, and the whole experience was smooth and stress-free. He took the time to answer all our questions, made sure everything was set up perfectly, and left the workspace spotless. You can tell he takes pride in his work. We?re beyond happy with the results and grateful for the excellent service"

"Called Monday morning, and they were out that day to evaluate and troubleshoot my lack of water pressure. Returned next day with crew and parts to install new well pump. Completed the job and had water running again in the afternoon. Cannot say enough about the professional service of Hardie Plumbing. Excellent Crew and excellent service."

"The company plumbers arrived on time. They got right to work and completed most of the jobs within an hour. I am pleased with their work. They did not repair my instant hot water dispenser, because their price was too high for me."

"We have a lot in Sammamish with a seaonsal stream and pond. Since our first month in the house, in 2007, we've had annual flooding in our basement. PermaDry promised that they could fix our basement flooding problem with a new interior drainage system that would capture the stormwater seeping between the footings and foundation walls. I was skeptical, but they offer a lifetime warranty, so it seemed like I had nothing to lose. The installation took three days, and just two weeks later we had a three day storm, with 2-3 inches of rainfall. Our yard was flooded extensively. In fact, it was the worst exterior flooding we've experienced since our first November in the house. The creek and pond overflowed into the surrounding yard. I can report that the basement remained completely dry for the duration of the storm. In past storms, much less severe than this one in 2015, I could detect water rising through cracks in exposed areas of the basement floor. This year I saw no moisture at all. The system worked flawlessly, and as promised. If you have basement or crawl space flooding problems, you should call these folks. They know what they're doing.

Water Softeners FAQs, answered by experts

If your water softener repair is fairly straightforward, like a simple filter replacement, then you can probably do it yourself with little risk. However, anything beyond a simple fix should be addressed by someone with extensive plumbing expertise to avoid costly water softener problems, like leaks. 

That said, even simple problems can be complicated to diagnose, particularly if your water softener is attached to a whole-house treatment system. So, unless you feel absolutely certain that the problem is an easy fix that you can take on yourself, it's probably best to hire a plumber to diagnose and fix the problem.

Selecting the right system depends on testing your water to understand the contaminants present and considering your household's water usage and specific needs, such as removing specific contaminants.

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.

The main difference between a water softener and a water filter is what they remove from the water. A water softener is specifically designed to remove hard minerals, while a filter removes a wider range of contaminants above a certain size, such as bacteria and other impurities. If your primary goal is to remove minerals, a softener is the best choice. If you want to remove various contaminants for safety or taste, a filter is more suitable. Filters are also typically less expensive to install. Depending on your water supply's specific issues, you may need to install both systems for comprehensive treatment.

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
