Struggling to choose between casement and double hung windows? Let’s uncover which option stands the test of time—and what you should consider for your next project.
Casement windows often last longer than double-hung types thanks to their design and fewer moving parts, but proper installation and maintenance truly decide longevity.
In my career at Hoglad, I’ve seen firsthand how window selection impacts building lifespan and maintenance workload. The right window design can save you years of headache. Let’s dive into key considerations—beyond just a simple durability contest.
What are the disadvantages of casement windows?
Casement windows sound like a perfect option—until you count the drawbacks, which can frustrate even seasoned pros.
Casement windows can have issues with mechanical hardware, require clear space outside, and may be vulnerable in strong wind areas, making them less ideal in some situations.
Here’s what I see most often when talking with contractors like Michael and dealers like Ahmed. Casements rely on a crank or lever system, and while it operates smoothly, these mechanisms can jam or wear out with heavy use. They also require unobstructed exterior space to open—something that’s not always practical for tight urban projects. And if you’re in a windy location (think Leon’s New Zealand sites), casement sashes can catch gusts and slam shut or suffer damage.
| Disadvantage | Details |
|---|---|
| Hardware Wear | Crank systems prone to mechanical failure |
| Clearance Needs | Requires open exterior space |
| Wind Vulnerability | Can catch wind and risk damage |
| Cost | Typically higher than double hung |
In my own factory, we advise customers to consider project location and maintenance culture before specifying casement windows—it’s not one-size-fits-all.
Which is better, window casement or double hung?
Choosing between casement and double hung? Your project’s needs, budget, and climate will shape the best solution—not just the window type.
Casement windows offer better air sealing and views, while double hung windows excel in versatility and ease of cleaning—each has strengths suited to different priorities.
Having helped both homeowners (like Emily) and procurement managers (like Leon) compare these styles, I notice casements deliver a superior weather seal. Their design presses the sash tightly against the frame, reducing drafts—perfect for cold climates or premium energy savings. Double hung windows, by contrast, let you open both the top and bottom sash, making cleaning and air flow a breeze (especially in multi-story homes). Maintenance is easier, and they cost less up front—but you’ll trade off a bit on insulation. Here’s a quick side-by-side:
| Feature | Casement | Double Hung |
|---|---|---|
| Ventilation | Maximal, full opening | Moderate, two sashes |
| Weather Sealing | Excellent | Good, may develop leaks |
| Cleaning | Exterior harder to clean | Easy, tilt-in sashes |
| Cost | Higher | Lower |
| Durability | Often better with upkeep | Good, with regular service |
When advising Hoglad clients, I always ask: What matters most to you—performance, price, or practicality? That determines the winner.
Do casement windows last longer?
Wondering which window will stay strong over time? Maintenance and environment matter more than type for true durability.
Casement windows, with proper hardware and care, often outlast double hung styles—mainly due to their fewer moving parts and tighter seal against weather elements.
Over two decades at Hoglad, I’ve seen casement windows remain sturdy after years of wind, rain, and sun—if owners keep the hardware lubricated and the seals intact. Double hung types are structurally solid, but their sliding tracks and balances require more frequent adjustment and cleaning. Heavy use or poor installation will shorten any window’s life, so careful selection and maintenance routine is key. Here’s a quick chart:
| Factor | Casement | Double Hung |
|---|---|---|
| Typical Lifespan | 20+ years | 15–20 years |
| Failure Points | Crank, seals | Tracks, seals |
| Maintenance Need | Moderate | Higher |
| Weather Resistance | High | Moderate |
I always tell my clients at Hoglad—the window isn’t just a purchase, it’s a partnership for decades.
Do casement windows leak more?
Worried about leaks? A window’s design and installation process play a bigger role than its type alone when it comes to water infiltration.
Casement windows generally leak less than double hung styles because their sash presses tightly against the frame, but poor installation or aging seals increase risk.
Many homeowners (like Emily) are concerned about water leaks, especially in rainy climates. Casement windows have an edge thanks to their compression seal—they literally seal tighter as wind pushes against them. Double hung windows rely on sliding tracks, which can develop small gaps over time and let in moisture or drafts. But the biggest culprit is installation: gaps, warped frames, or shortcuts by installers leave both styles vulnerable. So, whether I’m briefing contractors or helping a dealer prep a showroom model, I always stress the need for professional fitting and regular gasket checks. See below:
| Style | Typical Leak Points | Seal Strength | Best Practice |
|---|---|---|---|
| Casement | Along seal & hardware | High | Inspect gaskets regularly |
| Double Hung | Track & meeting rails | Moderate | Maintain tracks, adjust fit |
To truly avoid leaks, your best bet is working with trusted suppliers and skilled installers—like our team at Hoglad.
Conclusion
The winner between casement and double hung depends on your needs. Both can last decades with the right care—choose quality and fit for peace of mind.
