A local crew that treats your house like our own.
Since 2008 we've helped thousands of Chicagoland families get more comfortable, safer and better-looking homes, one project at a time.
Since 2008 we’ve replaced windows, doors and siding on 3,950+ homes across Chicagoland, with a 99% client satisfaction rate and an A+ from the Better Business Bureau.
Built on quality, kept going by referrals.
Apex Windows started in 2008 with a simple idea: homeowners deserve contractors who show up on time, explain things clearly and do the job right. No shortcuts, no surprises, no pressure.
Today we serve families across Chicagoland, with deep roots around Lemont, Orland Park and Naperville. Our team speaks English and Polish, so nothing gets lost between the estimate and the final walkthrough.
Whether it's one window or a whole new exterior, we handle it with the same care. That's why so much of our work comes from neighbors recommending us to neighbors.

The same four promises on every job, whether it's one storm door or a whole new exterior.
