5.0 Brian B. South Elgin, IL

It was great to work with Mark from start to finish. Their prices where very fair and the work was quality. Other companies wanted to open up my walls and charge me extra labor. Marks team came in and installed everything within 2 hours with no extra labor to my home. The main plumber was very experienced and even fixed other parts of my pipes that were not part of the original project. Great service all around.

I thought I wanted a reverse osmosis whole house water filtration system. the thing I do not like about that is it wastes a lot of water and takes out everything including the minerals. I also have very limited space to install it in. mark installed a whole house water filtration system that is the next best thing to reverse osmosis and was able to install a second filter that needs to be changed out yearly but gets rid of bad stuff the big unit did not. it will remove ninety eight percent of all the bad stuff I do not want in my water. he came out soon after I asked for an estimate and sent the quote right away and was able to install it within days of that so very fast. no more strong chlorine smell and water pressure is normal. sorry to say I had a closer look at the way it was installed and saw they used pvc plastic pipe leading from my incoming water meter to the water filtration system and from the system to my incoming water line. I thought pvc is only supposed to be used for drainage so they did not do the job up to code that i am familiar with. I bought a water filtration system because I am concerned about toxins in the water not to have more toxins added cancerous nonetheless with pvc pipe bringing the filtered water into my house for usage. very disappointed. just contacted mark to have him use copper instead of plastic. he came back and switched out the plastic for copper. mark is good with customer service. i am still waiting for water test results. i would like to know the difference between before and after installing the system for my water quality to know if it was worth getting it or not. i would like to know how much difference it makes. no idea how long it takes to get those water tests results...really want to see a significant difference i am hoping for.

From the quoting process to the check in after install, Mark was professional, thorough, and very knowledgeable. I thought I needed a whole house filtration system but after checking, Mark said I only needed a softener. Mark followed up to make sure everything was working well - the water in my house is noticeably softer after only a few days. I would highly recommend Chicago Water Pros for you water treatment needs!

5.0 Jacqueline G. Crete, IL

Mark installed an osmosis system and troubleshooted my old water softener. Turns out, I didn't need a new system. Culligan waters wanted to sell me parts costing more than a new softener. Very reasonably priced and professional.

5.0 Nancy C. Huntley, IL

Mark, the owner, was fantastic! Their pricing was the best I received over 6 companies. They went over and beyond to make sure our system was installed correctly and helped us with our garbage disposal install and new faucet. I would highly recommend Chicago Water Pros hands down!

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
