Get matched with top water treatment pros in Grayslake, IL

"Very satisfied with their job. Excellent work. Will definitely recommend them for plumbing work, especially water treatment / filtration projects. We rate them 5 stars."

"The technician came on time and, although it took him longer than expected to install the system, he installed it and demonstrated the system for me. The next day, I noticed there was still water on the concrete close to the system but, I figured it was residual water. Apparently the system was leaking. Two days after install I contacted Leaf and advised them that the system was leaking. Early, the next business day, they arrived and repaired the leak and made sure I was happy. My system seems to be working well and I am satisfied."

"He did a great job going over my questions and explaining the water heater, checking the plumbing and making suggestions for the future."

"The experience beginning with Scott coming out to test the water to Jim installing the water softener tank and reverse osmosis unit was great. They are very professional and informative and the price was just right. I will highly recommend and will refer this company to any family or friends looking to improve their water."

"We had our ejector pit pump go out, had a few people recommend Cosmic plumbing. Called and within 2 hours they had the pump back up and running! Can’t thank Chad enough for getting it fixed so fast. Could have been a disaster. Competitive pricing. Highly recommend!"

"Everyone from the sales person to installers were great. I love our new HVAC system!"

"The salemam put on an hour presentation so that I could see my bad water verses the filtered water. He was patient with me and most importantly he didn t act as if he was wasting his time and assume that I couldn t pay for the system. The system works great and I saw a difference immediately. The system was installed neatly and I although I initially inquired about the water system for bathing and washing only; I also purchased the reverse osmosis system for drinking water. They are pricey though."

"There was a delay in removing the water softener due to Covid but after 4 months in hiring a handyman, it was resolved and they came out to recheck the softener to make sure it was working properly. Excellent water softener and free service on it for two years."

"Dave's sons were great. They installed a new water softener. They were on time and very courteous. Once the install was complete, they told us how to use the system, what kind of salt they recommend. They were great answering all of our questions. We highly recommend using this company."

"Mark, sales, & Rob, installer, were fantastic. They were respectful of the Covid-19 safety protocols, were efficient with the installation of my whole house water filtration system and the cost was exactly as quoted. Mark followed up a couple of days after the install to ensure we were satisfied. Iâ d highly recommend them for any water services!"
