Diagnose Your Water Quality for Free

Hardness? Iron? Hidden Contaminants? Mast Family Culligan provides a FREE basic water test to identify water issues affecting your water.

Why You Need a Professional Diagnosis

We believe you shouldn’t have to pay to find out what’s in your water.

Here is why we offer a comprehensive in-home analysis to every homeowner in Southwest Florida:

  1. Southwest Florida’s Water is Too Complex for “One-Size-Fits-All” With hardness levels swinging between 16–40 grains per gallon, plus localized spikes in iron and sulfur, a generic system from a big box store is destined to fail. We customize the solution to your specific address.
  2. 50+ Years of Local Expertise We have been diagnosing Southwest Florida’s unique water issues since 1975. We don’t guess, we use decades of local data to get it right the first time.
  3. Evaluate Your Current System (Any Brand) Already have a softener? We test your water after it flows through your equipment to verify it’s actually working. If it’s failing, we give you honest data and repair options, no pressure, just proof.

Don’t guess. Know. Whether your water smells off, your skin feels dry, or you just moved in, let us give you the answers you need for free.

What We Look For (And What Requires a Lab)

Southwest Florida’s water is complex. Our free analysis identifies immediate water quality issues, while specific health contaminants require specialized laboratory testing:

PFAS ("Forever Chemicals")

Found increasingly in Southwest Florida, these man-made compounds are linked to immune system risks and are difficult to eliminate. Note: Due to their complexity, PFAS requires a specialized laboratory test (not included in the free in-home analysis).

Hard Water

Hardness destroys appliances and requires you to use up to 65% more cleaning products to get results. Our free test gives you an exact grain-per-gallon reading immediately.

Bacteria

Unlike city water, private wells are not chlorinated. The only way to ensure your well is free of coliform or E. coli is a certified lab test. Note: This requires a 2-4 day laboratory incubation period.

Chlorine

Municipal treatment keeps water safe to tap, but the residual chlorine dries out your skin and makes hair brittle. We test chlorine levels right at your kitchen sink.

Total Dissolved Solids (TDS) & Salts

High levels of dissolved salts (common in local surface water and some wells) can ruin the taste of coffee and tea. We measure your TDS levels instantly.

Fluoride

Commonly found in municipal supplies. While treated, excess levels can cause issues for some families. If you have concerns, we can arrange a specialized test to determine exact levels.

What To Expect From Your Free Water Test?

  1. Tests your water right at your kitchen sink (15-30 minutes)
  2. Provides a written report you keep (regardless of whether you buy anything)
  3. Explains what the results mean (in plain English, not jargon)
  4. Shows you custom solution options (no pressure, no sales tactics)

They are great. They delivered my waters asap. They answer all my questions.
They came at the time they were supposed to. They were very polite. They replaced the things that needed to be replaced and we discussed a preventive way to hope that it doesn't happen again from rain getting into the control panel, they're very polite and courteous and this is usually what I expect and they outdid theirselves

We had our sink filter installed a year ago and have been very pleased with it over the past year. Had our annual service call today and filter change. At ever step they’ve been professionally, courteous and prompt.
Been with Mast Family Culligan for over 15 years. Their service has been nothing short of great. Their delivery drivers are top notch. Been more than 1 occasion where I forgot to put out my empty bottles and they’ve knocked on the door to see if I needed water, I always did. If you are looking for a reliable water service you can’t go wrong with Mast Family Culligan.
Great techs. Always cheerful and know what they are doing. I love my water osmosis unit under my sink.
I got Culligan filtration system installed back in February of 2026. It's been an amazing experience since. However; water stop flowing in my home on Saturday, August 22nd, 2026. The technician over the phone was helpful. We went through the process of turning on the bypass, which caused water to flow, but the smell was awful. Rick Velez, Technician came out on Monday, got everything running the way it should. Rick customer service skills was professional and very upbeat, which was very welcome.Thank you Culligan water 💧
I'm so elated about my system and the Platinum Program benefits. The Technician that comes by to take care of my equipment is Logan Haack, and I want to make sure I give him a massive shout out for being so thorough. This guy works so hard and is so competent in his job, AND so friendly and professional as well. He literally goes above and beyond to make sure my system is not only functioning effectively, but that I am aware of everything during the process and happy with the results. He's awesome.
Joe is a very good delivery guy excellent performance….
Culligan always have worked with excellence for my family and me for many years. This is a company that values customers and that employs outstanding people.
They are very professional and listen to what customers have to say.
Great service! Great water quality’!
I had a wonderful experience with Culligan from start to finish! Bryan, my sales representative, was incredibly kind, knowledgeable, and helpful in making sure I understood what I needed for my home. He made the entire process easy and went above and beyond to get me scheduled for installation as quickly as possible.Jeremy, my installation technician, was equally fantastic. He installed both my whole-house water softener system and the point-of-use system in my kitchen. He was kind, professional, efficient, and took the time to walk me through how everything worked and how to use and maintain the systems. He made sure I felt completely comfortable before he left, and the entire installation was completed in no time.The level of service from both Bryan and Jeremy was exceptional. I’m extremely happy with my experience and would absolutely recommend Culligan, and especially Bryan and Jeremy, to anyone considering a water treatment system for their home!
Great professional service
The installers arrived right on time and were very efficient in setting up the system. They also helped me understand the new system and where the pipes were located in our garage. Thank you Gus and Dillion!
