Are your aluminum windows drafty, stuck, or just looking tired? Learn the steps, the options, and the tips you need to make a smooth upgrade—whether you DIY or hire help.

Yes, aluminum windows can be replaced—either just the glass or the entire window, depending on their age, condition, and your goals. Modern replacements offer better insulation, comfort, and curb appeal.

Window replacement can feel overwhelming, but you’re not alone—many homeowners, contractors, and dealers face the same crossroads. Let’s break down the main questions so you can approach your project with confidence and clarity.

Can aluminium windows be replaced?

Old, leaky windows can turn comfort into frustration. If you’ve considered replacing aluminum windows, you’re in good company—technology and design have moved on significantly.

Absolutely! You can replace aluminum windows with new aluminum, vinyl, fiberglass, or aluminum-clad wood units to gain performance and style upgrades.

Types of Replacement and Upgrade Paths

Not all replacements are the same. Here’s how your choices line up:

Modern windows offer improved thermal breaks, lower maintenance, and lots of customization—something we’ve made core at HOGLAD. If you want to balance energy savings, appearance, and cost, it’s worth weighing both full-frame and retrofit solutions.

Can you replace just the glass in an aluminum window?

A shattered pane can ruin a perfectly good window. But do you need to replace the whole unit?

Yes, if your aluminum window’s frame is sound, you can usually just replace the glass. This is cost-effective for cracks or fogging, but old frames may limit improvements.

When Glass-Only Works—and When It Doesn’t

Let’s consider the technical and economic factors:

In my experience, serious corrosion or outdated single-pane frames in our industry rarely justify glass-only fixes. For owners wanting true upgrades in comfort and energy savings, a full window swap pays off—especially with today’s customizable systems. Still, if the goal is quick, low-cost fixing (e.g. rental or budget sell), glass-only can make sense.

Should I replace my old aluminum windows?

Drafts, condensation, tough-to-open sashes—sometimes a window is just past its prime. Should you invest in new ones?

If your aluminum windows are single-pane, inefficient, or hard to operate, replacement usually delivers far better comfort, efficiency, and curb appeal than repair.

Weighing Repair Versus Replacement

Here’s how most homeowners and pros weigh the options:

When do I suggest repairs? If a frame is straight and hardware is fine, re-glazing, weather-sealing, or hardware fixes can sometimes extend life. But if corrosion or routine headaches persist, full replacement means less stress, lower energy bills, and more choices in look and feel. Many HOGLAD clients are stunned by their room’s transformation after an upgrade.

Can I install replacement windows myself?

DIY can save money, but replacing windows isn’t for everyone. The wrong step, and you could face leaks or failed inspections.

You can install aluminum replacement windows yourself if you have construction skills, the right tools, and patience—otherwise, professional help is best for lasting results.

DIY or Pro—How to Decide

Here’s how to assess if DIY makes sense:

I always suggest testing your skills with one small window. If in doubt, a professional installer⁸ brings peace of mind—especially with waterproofing, large windows, or walls like brick/stucco.

Conclusion

Replacing aluminum windows is doable and worthwhile. Modern options mean better comfort and style—just weigh your skills and goals before you DIY or call in pros!
