Our Window Installation Process

Window Consultation

During this meeting, we’ll discuss the types of windows you’d like installed or necessary repairs and then schedule a time to begin the process.

Window Sizing

We’ll visit your property to measure the size of your windows and then send you a quote based on your project’s requirements.


Our team will remove the old frames, jamb liners, and sashes. After this, they will caulk and insulate the openings before installing the windows you have ordered. Then, they’ll finish your window installation project by shimming, caulking, and sealing to ensure that your energy-efficient windows are safely and securely in place.

Once your project is completed, one of our team members will contact you again to ensure you are pleased with our window replacement service.

Words from
Our Clients

Service technicians were polite and professional. They removed damaged parts of the window, cut new pieces to fit, stained the wood, and installed them nicely. The team cleaned up as if they were never there. I would recommend Apex Windows Werks for your window repair. Friends living near me ordered window repairs based on my recommendation as well.

Glenn Kaupert Chicago, IL

Two windows in my house were cracked for a few years. The crack started to get worse on one of them, so it was time to get the glass replaced. The estimate was fair and when the crew came out to replace the glass, they were clean and neat and made sure it was done correctly. I would use them again if a future need arises.

Pete Nowicki

Very kind people. Respectful of our property. Such a cold weather day they worked & didn’t complain’. And Price was much more reasonable than replacing the whole bow picture window. One of the workers personally dropped off a needed window crank piece & installed it the next day. Highly recommend.
