Our three-flat had a serious problem with our sump pump this winter. We chose Chicagoland Quality Plumbing based on its strong reviews here and were not disappointed. Mr. Flores kindly agreed to met us late in the day (for him) and had the problem fixed in short order. We were grateful he was willing to be so flexible and was so effective in solving the problem. A few weeks later, after heavy rains, a problem recurred. He willingly came out again, despite very wet conditions, and again made the repair quickly and explained what had gone wrong. Despite his time and the inconvenience to him, he did not charge us again. We were impressed by his honesty, skill and professionalism, and will call him again when needed, for our building or for our individual units. Thanks for the excellent work and outstanding response when we badly needed your help.
