What Our Customers Think About #1 Plumbing

Kim K.

“Mike did a great job replacing the galvanized pipes and the hot water heater. They stayed until the job was complete (9:30 pm) and left no mess behind. It’s great having water pressure and HOT water. Thanks Mike!”

Ken Stojak

“I would highly recommend Number One Plumbing to anyone. They went above and beyond to get water service restored at my home.”

Chris M.

“I completely remodeled my condo downtown Chicago. Mike did the work himself and all I can say is his work is fantastic. The city inspectors had no problem approving his work….If you use MIKE you will be pleased. Go for it!”
