Factory Direct Pricing You Can Trust

What does factory direct pricing mean for you? It means skipping the middleman and saving money. Instead of paying inflated prices at big-box stores, we bring premium windows directly from the production line to your home.

To ensure perfection, every window is double-measured and custom-built to fit your home like a glove. With us, you’ll enjoy superior quality, tailored service, and competitive pricing — that’s what factory direct pricing is all about.

Energy-Efficient, Green Replacement Windows

At The Window Source of Chicago, almost all our windows meet Energy Star® standards, making them eco-friendly and energy-efficient. Our windows are designed with Low-E glass and argon gas insulation, which help:

  • Enhance overall comfort in your home

  • Minimize fabric fading from UV rays

Our Commitment to Excellence

Our business philosophy is simple — we treat people the way we want to be treated, and we aim to exceed expectations in everything we do. Here’s how we deliver on that promise:

  • Keeping our word: Whether it’s returning calls promptly or arriving on time for appointments, we value your time and trust.

Kim's so responsive and easy to work with. Not only do my new windows look great, Kim made sure to involve the manufacturer of my home's walls so that these newly-installed windows would not void my warranty. Grateful for Window Source's care!

Great company to work with. Kim is awesome. Very responsive and communicative. She managed the entire window replacement project from start to end. Their technician who installed the windows was probably the hardest working person I have ever met. He was quiet, courteous and very neat and clean.

Nan Clarke

This was an excellent service from start to finish. David showed me a sample of what I was purchasing and clearly explained the entire process. There was NO pressure with some special deal only good for that moment. I sat through three of those, so David's approach was refreshing and exuded honesty...
