Why Replace Your Windows?
Windows that were installed 15 or 20 years ago—even quality windows from that era—simply can't match the energy performance of modern products. Technology has advanced dramatically, and the improvement in thermal performance, noise reduction, and UV protection between older single and double-pane windows and today's best options is significant. Here are the most common reasons. St. Louis homeowners invest in new windows:
- Drafts and cold spots near window areas in winter
- Condensation or fogging between glass panes—a sign of failed seals
- Difficulty opening, closing, or locking windows
- Visible damage—cracked frames, broken glass, or deteriorated seals from storm impact
- High energy bills indicating poor thermal performance
- Outdated appearance that affects curb appeal and home value
- Noise from outside that penetrates more than it should
Energy-Efficient Window Options
Modern replacement windows offer substantial improvements in insulation, solar heat gain control, and air infiltration compared to older products. We offer a range of energy-efficient window options—including double- and triple-pane configurations, low-E glass coatings, and argon-filled insulating units—and will help you select the product that best balances performance, aesthetics, and budget for your specific home and goals.
For St. Louis homeowners, the combination of hot summers and cold winters makes the right window selection particularly impactful. A well-chosen window package can deliver meaningful year-round energy savings while improving comfort throughout both seasons. Our team will explain the performance ratings and help you make a genuinely informed decision.
Windows as Part of a Full Exterior Project
Window replacement is one of our most commonly combined services—frequently paired with new siding or a roof replacement for a complete exterior refresh. When windows and siding are replaced together, the installation can be properly integrated and sealed for optimal energy performance, and the finished result has a cohesive, intentional appearance that a single-service project can't always achieve. We coordinate multi-service projects efficiently, with one team and one point of contact throughout.
Window Replacement Frequently Asked Questions
How long does window replacement take?
Most residential window replacement projects in the St. Louis area are completed in one to two days, depending on the number of windows being replaced and the complexity of the installation. Individual window replacements—a single window or a small number of units—can typically be completed in a few hours. Larger whole-house replacement projects require more time but are scheduled and managed to minimize disruption to your household. We'll give you a clear timeline estimate during your free estimate appointment.
Will new windows actually lower my energy bills?
In most cases, yes—particularly if you are replacing older single-pane or early-generation double-pane windows with modern, properly rated units. The improvement is most pronounced in homes where existing windows are drafty, have failed seals (visible as fogging between panes), or are original to an older home. Modern low-E glass, insulating gas fills, and thermally broken frames significantly reduce heat transfer in both summer and winter. While the specific savings depend on your home's size, existing insulation, and how you heat and cool, energy savings from quality window replacement are well-documented and consistently meaningful for St. Louis homeowners.
Can storm-damaged windows be covered by insurance?
Yes—storm damage to windows is frequently covered by homeowner's insurance, particularly when damage is caused by hail, wind, or falling debris. Coverage depends on your specific policy terms and how the damage is documented and presented. Luitjens Exteriors handles storm damage documentation and insurance claim support for window damage as part of our broader storm restoration services. If your windows have been damaged in a storm event, contact us for a free inspection before filing your claim—our documentation can significantly improve the outcome.
