Apex has done two projects for me, and both have been impeccable. A lot of companies just ghost you because they don’t want your business, but Apex has responded to every voicemail or email I’ve sent them. Their work is great. I would definitely call them first if I need anything done again.

One of the best decisions I made this year was choosing Apex Exteriors to replace our roof. From the moment I contacted them to the day the job was completed, the entire experience was excellent. Chris and Jim, our project managers, kept me updated every step of the way and communicated promptly about any changes or updates. The crew was fantastic — they worked efficiently, did a great job, and the finished roof looks amazing. Their pricing was very competitive and ultimately the best among the roofers I considered. I highly recommend Apex Exteriors. You really can’t go wrong with this choice!

They handled my window installations quickly and when they were done everything was cleaned up as if they weren't there. A Quality Commitment, Nick, went to each window to confirm all parts worked properly as well as made sure the windows closed and latched before the workers left. The workers were very respectful and a delight to deal with. I am currently contracting the company again to do my siding.

Practical Answers About Our Window
And Door Installations
If you’ve never replaced windows or doors before, it’s normal to wonder about timing, disruption, and what makes one product better than another. These FAQs cover the groundwork we go over with homeowners so you can move forward with clear expectations.
Am I Within Your Service Area?
Our company is based in South Elgin, Illinois, but we install replacement windows throughout the Chicagoland region. Our red work trucks can be seen from St. Charles to Naperville, Hinsdale to Arlington Heights, and Evanston to South Wisconsin’s Lake Geneva. Visit our Service Areas page for more information, or call us if you’re unsure.
Can I Finance My Window Project With Apex?
Financing window replacement is common, especially when replacing a large number. Other customers finance to get higher-quality or longer-lasting windows. At other times, they finance because windows are just one part of a much broader project scope. In any case, we can help. Visit our Financing page for more info, or call and let us know you’re interested.
How Long Will My Window Replacement Project Take?
This all depends on your situation. For example, installing 20+ windows takes our in-house teams longer than 5-10 windows. Are these somewhat conventional windows, or highly customized and being installed in harder-to-reach places? Your timeline will be clearly outlined at the beginning and throughout every step of your project. You’ll always know who’s doing what, when, and for how long.
Is Replacing Windows With Apex On The High-End?
