What happens when two skilled and successful plumbers join forces? They become Chicago’s team of super plumbers (also known as Northwest Plumbing & Piping)! NP&P was born from the merger of Tom Catenzaro’s 30 years of plumbing experience with Jason Kjaer’s 20 years, and together, they have become a force to be reckoned with. Whatever your plumbing needs, you’ll find fast, skillful, and ethical service from Northwest Plumbing & Piping.
