Mike was clean, very professional, went the extra step, tested our water, ordered, picked up and installed new Charger water softener, explained about how it works, removed old water tank, he also drained water heater thoroughly until water was running clear. He gave us plenty of time to make sure all was well. Later the same day Moen kitchen faucet water outlet broke off in my hand (not caused by anything Mike did, the weld broke. Mike came next day to replace with new Moen and left with everything working properly. I give the highest rating to Mike and Lake Cook Plumbing.
