Windows Crafted for Mountain Living
At Weldon Enterprises, we specialize in professional window installation designed for Colorado’s mountain climate. As a Pella and Milgard certified contractor, we combine premium products with expert craftsmanship to deliver windows that are as durable as they are beautiful. Whether you’re updating an older home or building new, our team ensures every installation meets the highest standards of performance and style.

Built for Colorado’s Unique Climate
Living in Clear Creek County means dealing with unique environmental challenges—high elevation, intense sun exposure, heavy snow, and fluctuating temperatures. Standard windows often fall short in these conditions, leading to drafts, poor insulation, and higher energy bills. That’s why we install windows specifically engineered for mountain environments, helping homeowners maintain year-round comfort while reducing heating and cooling costs.
Energy Efficiency That Works Year-Round
Energy efficiency is a major benefit of our certified window installations. Pella and Milgard windows are built with advanced glass technology, tight seals, and insulated frames to minimize heat transfer. This not only lowers energy consumption but also protects interiors from UV damage, preserving flooring, furniture, and finishes. With Colorado’s bright, sunny days, this added protection is a key advantage.
Designed to Complement Your Home
In addition to performance, our installations enhance the look and feel of your home. Large, black-framed windows capture sweeping mountain views and bring in abundant natural light, while a variety of styles and finishes allow you to customize your home’s appearance. From modern designs to timeless classics, we tailor solutions to fit your vision.
Experience That Sets Us Apart
With over 25 years of experience, Weldon Enterprises has earned a reputation for precision, reliability, and customer-focused service. We take pride in delivering window installations that not only meet manufacturer certification standards but also stand the test of time in Colorado’s rugged environment.
Key Benefits of Professional Window Installation
Improved Energy Efficiency
Modern window systems are designed with insulated glass, low-E coatings, and airtight seals to reduce heat transfer. They help maintain consistent indoor temperatures by preventing heat loss in winter and heat gain in summer. This efficiency lowers HVAC usage, reduces energy bills, and creates a more sustainable home with better thermal regulation across all seasons.
Enhanced Indoor Comfort
Properly installed windows eliminate cold drafts and heat infiltration, ensuring a stable interior temperature year-round. Advanced glazing reduces UV exposure, which protects furnishings and flooring from fading. In addition, high-quality window systems help block external noise, contributing to a quieter, more peaceful indoor environment, making daily living more enjoyable and consistently comfortable.
Boosted Property Value
Replacing old windows with energy-efficient, low-maintenance designs adds both visual appeal and functional improvements to a home. Prospective buyers appreciate updated windows for their energy performance, aesthetics, and ease of use. As a result, new window installations often increase a home’s resale value, improve buyer interest, and reflect responsible home maintenance and investment.
Increased Natural Light
Well-designed window placements allow more sunlight into the home without sacrificing insulation or comfort. Natural light enhances interior spaces, boosts mood, and helps reduce the need for artificial lighting during daylight hours. The increased brightness makes rooms feel larger, more inviting, and energy-efficient—while contributing to the overall aesthetic of the home’s interior.
Better Ventilation
High-quality windows offer adjustable ventilation options to support healthy indoor air quality. Whether using double-hung, casement, or sliding styles, homeowners can control airflow for fresh circulation and moisture reduction. This helps balance indoor climate, expel stale air, and minimize the buildup of allergens, leading to a more breathable and pleasant living environment.
Safety and Security
New windows are built with enhanced locking mechanisms and stronger materials such as laminated or tempered glass. These upgrades improve resistance to forced entry and accidental breakage, increasing overall home safety. Advanced window technology also includes child safety features and impact-resistant designs, offering peace of mind for families prioritizing both security and durability.
Frequently Asked Questions
What makes Pella and Milgard windows better suited for Colorado’s mountain climate?
Pella and Milgard windows are engineered with advanced glass technology and insulated frames that perform exceptionally well in high-elevation climates. They provide superior energy efficiency, UV protection against Colorado’s intense sun, and durability to withstand snow, wind, and temperature swings common in mountain environments.
Why is it important to have a Pella and Milgard Certified Contractor install my windows?
Certification ensures your windows are installed according to strict manufacturer guidelines, protecting both performance and warranty. A certified contractor like Weldon Enterprises guarantees a precise fit, proper sealing, and installation techniques that maximize energy efficiency, comfort, and long-term durability.
How long does a typical window installation take?
Most standard window installations are completed in one day, depending on the number of windows and the home's condition. Larger or custom projects may take additional time for preparation and finishing.
Can new windows really lower energy bills?
Yes. Energy-efficient windows reduce heat loss, minimize drafts, and block UV rays. This decreases your heating and cooling load, which translates to noticeable savings on monthly utility costs over time.
Are permits required for window replacement?
Permit requirements vary by municipality. In most cases, replacements that alter window size or structure require permits. Our team handles all necessary paperwork to ensure compliance with local codes and regulations.
What types of windows are best for cold climates?
Double-pane or triple-pane insulated windows with low-E glass and gas fills are ideal for cold climates. These options improve thermal performance and reduce condensation issues common in high-elevation areas.
Do you work on older or historic homes?
Yes. We specialize in historic window restoration and replacement. We preserve the home's original appearance while improving energy performance and durability using modern, compatible materials.
How do I know if my windows need replacing?
Common signs include drafts, difficulty opening or closing, condensation between panes, or visible damage. Rising energy bills and faded furnishings also indicate failing window performance.
Are vinyl, wood, or fiberglass frames better?
Each material has pros and cons. Vinyl is low-maintenance, wood offers classic appeal, and fiberglass provides strength and insulation. We help select the best fit for your climate, budget, and design.
Can windows be installed in winter?
Yes. Our team uses cold-weather installation methods to ensure airtight sealing and proper adhesion even during colder months. Winter installs help prepare homes for harsh weather more efficiently.

Derek and his family team did an absolutely fantastic job remodeling my bathroom. His team were extremely respectful and communicated with me throughout the project. He used quality materials and his craftsmanship was superb. I was most impressed with his ability to stay on schedule. I gave him 2 weeks to do an entire bathroom remodel and his team delivered. He made it clear that it was his priority to meet my timeline which is a rarity in the industry. I would recommend him for anyone looking to do remodel/renovation work to their home. He will be doing my basement renovation next.
