Our Mission Statement
OUR PURPOSE IS TO ENHANCE AND ENRICH THE LIVES OF OUR CUSTOMERS, TEAMMATES, AND OUR COMMUNITIES BY PROVIDING WORLD-CLASS REMODELING PRODUCTS AND SERVICES. NOT ONCE, BUT FOR A LIFETIME!
Our Values and Promise to You
At Illinois Energy Windows & Siding, we’ve been upholding our customer-focused mission for decades now, and our dedication to 100% customer satisfaction hasn’t wavered in the course of our 27+ years of service. For you, our mission statement translates directly into several straightforward and uncompromising promises: best quality, best warranty, best service—all for a reasonable price.
Here’s what that means for you:
- Best Quality: We’ve selected windows, doors, gutters, and siding options that can withstand the Chicagoland climate with minimal maintenance.
- Best Warranty: We’re home of the True-Lifetime Warranty on parts and labor! In the rare event that your product does not perform as it should, we will make things right.
- Best Service: Our company is proud that over 27 years we have cultivated and created an amazing team in order to serve you. You will receive excellent service during your home improvement process, and if you ever required warranty service work in the future. Service and communication is one of our main focuses as a business!
Many of our customers are repeat customers whom we’ve helped in the past—for instance, previous window customers who now need more energy-efficient siding, or previous door customers who've decided to upgrade to better quality windows. We treat all of our clients, new or repeat, to the very same level of unsurpassed service.
