Window Replacement in Denver, Colorado
Replacing your old and outdated windows can transform your home’s appearance. While it may seem like a big and costly project, it comes with incredible benefits. Residential windows have a lifespan of 15-20 years. While some windows may last over two decades with proper care and maintenance, upgrading to more energy-efficient windows is a better choice.
Consider replacing your windows if the existing ones:
- Fails to open or lock properly and compromises the home safety and security
- Have become less efficient
- Have broken seals
- Have cracked and rotten frame, experiencing condensation, and allowing water intrusion
- Have experienced extensive storm damage or have worn out over time
- You want to upgrade to modern window designs during the renovation

FAQ's
How do I know when it’s really time to replace my windows, rather than repair them?
While some minor issues like broken hardware or weatherstripping can be repaired, there are telltale signs it’s time for full replacement. If your windows are drafty, have visible rot, condensation between panes, or are difficult to open and close, these signal deeper problems. Older single-pane windows also lack energy efficiency. At Colorado Western Construction, we assess both performance and structure before recommending replacement, ensuring you’re not investing unnecessarily in new windows unless it's the most cost-effective and long-term solution.
Will new windows actually lower my energy bills, or is that just a sales pitch?
It’s not just hype—modern energy-efficient windows can significantly reduce heating and cooling costs. In Denver’s variable climate, older windows often leak air or transfer heat easily. Our double- or triple-pane windows with Low-E coatings and argon gas fillings act as an insulating barrier, reducing the load on your HVAC system. While savings vary by home, many of our clients report a 15–30% reduction in energy costs annually, making window replacement a smart long-term investment.
Is it true that not all “energy-efficient” windows are created equal?
Absolutely. Energy efficiency isn’t just about double-panes—it involves frame material, U-factor, solar heat gain coefficient (SHGC), and installation quality. At Colorado Western Construction, we work with top-rated manufacturers and help you compare certifications like ENERGY STAR® and NFRC labels. We also guide you in selecting the right specs for Denver’s unique climate—balancing solar gain in winter with protection from intense summer sun.
Can I replace windows in the winter, or should I wait until spring?
Yes, we replace windows year-round—including winter. Our team uses proven cold-weather installation methods to ensure minimal heat loss and moisture control during the process. Denver’s winters can be unpredictable, but delaying replacement can mean months of higher energy bills and discomfort. We prep each opening carefully, install windows one at a time, and work swiftly to avoid exposure. Many homeowners appreciate off-season scheduling flexibility and even seasonal discounts.
Do replacement windows really increase home value, or is the return on investment exaggerated?
According to national remodeling studies, window replacement often offers one of the highest returns on investment—typically 70–80% at resale. But the benefits go beyond numbers. Buyers notice updated windows, especially energy-efficient ones, as it signals proper home maintenance. Enhanced curb appeal, improved insulation, and quieter interiors can give your home a competitive edge in Denver’s housing market. It's not just about aesthetics—it’s about long-term livability and performance.
What’s the most common mistake homeowners make when choosing replacement windows?
Many focus solely on price or appearance without considering installation quality or performance ratings. Low-cost windows may look similar but often lack durability or efficiency. The biggest impact comes from the installer, not just the product. Colorado Western Construction provides expert installation backed by warranty and local experience. We help you choose the right material (vinyl, fiberglass, wood-clad, etc.) based on your needs—not just trends.
How long does the average window replacement take?
Most standard window replacements take about 30 to 60 minutes per window. A typical home project can be completed within 1–2 days, depending on the number of windows and any structural issues encountered. Our process is streamlined—from property protection to final cleanup. We also inspect each opening and ensure perfect fit and insulation before moving to the next. You’ll never be left with an unfinished job or exposed opening overnight.
What’s the process for replacing my windows with Colorado Western Construction?
Our process starts with an in-home consultation, where we assess your current windows, measure precisely, and discuss your style, efficiency, and budget preferences. Next, we custom-order your windows for a perfect fit. Installation day includes setup, removal of old windows, insulation, sealing, and finishing trim work. After a full cleanup, we conduct a walk-through to ensure satisfaction. Our warranties cover both product and workmanship, so you’re protected from start to finish.
Are window replacements disruptive to my home life?
Most homeowners are surprised by how smooth the process is. We typically work room by room, so you're never completely displaced. Our team protects flooring and furniture, contains dust, and cleans up thoroughly after each installation. We also coordinate with you to minimize noise and disruption. Many clients continue working from home or handling daily tasks while we complete their project.
How do Denver’s climate and altitude affect my window choice?
Denver’s mix of hot summers, cold winters, and high elevation calls for high-performance windows. UV rays are stronger at altitude, making UV-resistant coatings and Low-E glass especially valuable. Windows also need to handle frequent freeze-thaw cycles and protect against drafts. At Colorado Western Construction, we recommend features like insulated frames, double- or triple-pane glass, and composite materials that perform well in all seasons and stand up to Colorado’s environmental stressors.
