Custom Exteriors

Northern Colorado’s Top-Rated Choice for Energy-Efficient Windows & Roofing

At Custom Exteriors, we don’t just install windows and roofs; we provide peace of mind for Northern Colorado homeowners. From replacing windows in the historic neighborhoods of Longmont to the growing communities in Windsor and the plains of Greeley, we understand that our local climate demands more from your home’s exterior.

Between intense high-altitude UV rays and the unpredictable hail seasons of the Front Range, your home needs materials that are as resilient as they are beautiful. That’s why we specialize in “A+ Rated” solutions, like the Pella Impervia, engineered to handle the specific temperature swings and wind loads of our service area without warping or failing.

Whether you’re looking to lower your Xcel Energy bills or protect your biggest investment from the next storm, our local crews are ready to provide the expert craftsmanship and honest service you deserve.

Colorado’s Trusted Partner for Premium Window Replacement

Replacing windows in Colorado isn’t just a home improvement project; it’s an essential defense against one of the most volatile climates in the United States. At Custom Exteriors, we specialize in high-performance window systems engineered specifically for the Front Range. From the extreme UV exposure at 5,000+ feet to the 100 mph wind gusts of the Eastern Plains, our team provides the local expertise required to ensure your investment stands the test of time.

With decades of combined experience in Northern Colorado and Southern Wyoming, we understand that a “standard” window isn’t enough for a Colorado home. We curate only the highest-rated products from industry leaders like Andersen and Pella, ensuring every installation meets rigorous energy codes and structural requirements. When you choose Custom Exteriors, you’re choosing a locally owned partner committed to transparency, master-level craftsmanship, and long-term energy savings.

Why Local Expertise Matters for Your Exterior Project

We find customers looking to upgrade with window replacements often focus on “price,” but in Colorado, the real value lies in performance. Our installation teams are factory-trained and deeply familiar with local building codes from Longmont to Cheyenne, ensuring your warranty remains valid and your home stays airtight.

Beyond the technical specs, we prioritize the homeowner experience. We are fully licensed, insured, and deeply embedded in the communities we serve. We don’t use high-pressure sales tactics; instead, we provide a consultative approach to help you navigate the complex choices of frame materials, glass packages, and local rebates. From initial consultation to the final walkthrough, our goal is to provide a seamless, stress-free upgrade that increases your home’s value and comfort. Contact us today and let the window team at Custom Exteriors refresh your home!
