Meet Noah & Joseph
JMack Window Washing was started by two friends, Noah Mack and Joseph Harmening — both students at Saint Ignatius College Prep. What began as a way to earn our own money turned into something we genuinely take pride in: leaving every window spotless and every customer smiling.
We're young, but we show up on time, work hard, and treat your home with the same care we'd give our own families. When you hire us, you're not just getting clean windows — you're supporting two local high schoolers chasing big goals, one streak-free pane at a time.
Give us a shot. We promise to earn your trust — and your five-star review.
