I'd count Schaefer's very high on a short list of maybe half a dozen of my most trusted and…read morefavorite local companies. Really just exceptional. As a Realtor, I've got to know who I can safely recommend to clients, and this one is a no-brainer for me. They do water softener, iron filter, and reverse osmosis installation and service, and even salt delivery. I've personally used them, and numerous clients of mine have done the same (including again just today). They're located in Watertown, WI (Jefferson County), which is just a little west of Oconomowoc, though they'll travel a decent distance. Today's client was in Richfield. This is a longstanding, family owned business, and their folks are polite, on time, reasonable, and really experts on all things water. As highly as I can recommend anyone, call Schaefer's with confidence. Please note, I get exactly nothing from anybody I recommend, but the knowing that I can do it with confidence is worth plenty to me and my work.

They are prompt, and always respectful of me and my home. Every visit they also check my two refrigerators to be sure they are filtering the water/ice properly. Call 2 months in advance, because they are busy and book fast. I would recommend their company over others that I have used in the past. Last year I purchased a water filter faucet from G&F. They have many designs and finishes to choose from.

Called Guthrie & Frey and they came out the same day and installed an iron filter the next day. Wow, I know that wasn't the usual time frame but they understood our concern. I would recommend them for anyone with an old or new water system. I think an RO system is next for our ice maker!!

So, whenever we have had to do maintenance on the system, we have called them for service. Their technicians are prompt, friendly and knowledgeable about the products. Recently, we felt the iron filter was not working well enough. We scheduled an appointment for Hanson to send someone over. Dustin came to check out our iron filter and determined that at 15+ years we had some hard choices to make. He walked us through our options, patiently answered my questions, and did not try and sell anything specific. We talked about replacing the water softener at the same time. He ran tests and confirmed it was in working order. We scheduled time for them to replace the iron filter. Again, Dustin and his assistant arrived on time, worked efficiently and cleaned up after themselves. He took the time to explain the whole setup to me and ensured I was comfortable with the work done. They are easy to work with and a great service-oriented company. I also love the fact they are heavily involved in the local community. Strongly recommend Hanson Soft Water for any water filtration needs. Wish more businesses were like them!

He came prepared with anything he needed, even if he had to rebuilt it. Turned out it was not my softener. Aaron took a quick look around, found the leak was the float switch on sump pump, told me the size, so I could let a plumber know & recommended a couple in the area. I actually found one exactly the same on Amazon & replaced it myself! If not for Aaron, I probably still would not know where this flood was coming from. He is a great asset to your company! I really appreciated him going above & beyond, when most contractors do what they come to do & they're out the door. It only took him a minute, but it saved me from more headaches & a lot of money. I can't recommend Aaron enough!!!! 10 stars!
