How Long Do Aluminium Doors and Windows Actually Last?

When investing in new doors and windows, one of the biggest questions homeowners ask is:

How long will they actually last?

If you’re considering aluminium windows or aluminium doors, the short answer is simple:

Quality aluminium systems can last 30–45 years or more.

But like most things in construction, longevity depends on more than just the material itself.

In this guide, we’ll break down what affects lifespan, how aluminium compares to uPVC, and whether aluminium doors and windows are worth the investment long term.

How Long Do Aluminium Windows Last?

High-quality aluminium windows typically last three to four decades, often longer when properly installed and maintained.

Unlike older timber systems that require regular treatment, or lower-grade materials that can warp over time, modern aluminium frames are:

• Structurally strong

• Corrosion resistant

• Powder coated for long-term durability

• Designed to withstand UK weather conditions

Premium systems such as Origin, Smart, and Cortizo are engineered specifically for longevity, with robust profiles and high-performance finishes.

How Long Do Aluminium Doors Last?

The lifespan of aluminium bifold doors, sliding doors, and aluminium entrance doors is similar — typically 30–45+ years.

Because aluminium is significantly stronger than uPVC, it allows for:

• Slimmer sightlines

• Larger glazed panels

• Reduced frame movement over time

That structural strength is one of the key reasons aluminium doors maintain alignment and smooth operation for decades.

What Affects the Lifespan of Aluminium Doors and Windows?

While aluminium itself is extremely durable, a few factors influence how long your system will perform at its best.

1. Powder Coating Quality

Not all finishes are equal.

Marine-grade or high-quality powder coating protects against:

• Fading

• Peeling

• Corrosion

• Discolouration

A professionally applied finish should last decades without needing repainting.

2. Installation Quality

Even the best aluminium system can underperform if installed incorrectly.

Proper:

• Levelling

• Sealing

• Fixing

• Load support

All contribute to long-term performance.

This is why correct surveying and installation are just as important as the product itself.

3. Hardware & Moving Parts

Handles, hinges, rollers and locks experience wear over time.

Premium systems use higher-grade components that:

• Resist corrosion

• Maintain smooth operation

• Withstand daily use

Hardware may need occasional adjustment or replacement long before the aluminium frame itself reaches end-of-life.

4. Environment

Homes in coastal or exposed locations require additional corrosion resistance. Choosing the correct specification from the outset ensures long-term durability.

Aluminium vs uPVC Lifespan

One of the most common comparisons is aluminium windows vs uPVC windows.

Here’s the realistic breakdown:

uPVC remains a cost-effective option, but aluminium generally offers greater longevity, strength, and premium appearance over time.

Do Aluminium Windows Require Maintenance?

Aluminium is low maintenance.

To keep your doors and windows performing well:

• Clean frames occasionally with mild detergent

• Lubricate moving parts annually

• Check seals periodically

There is no sanding, repainting, or intensive upkeep required.

Are Aluminium Doors and Windows Worth It?

If you’re planning to stay in your home long term, aluminium systems often provide better value over time.

They offer:

• Longer lifespan

• Slim, modern sightlines

• Higher structural integrity

• Excellent thermal performance with modern thermal breaks

When comparing lifecycle cost rather than just upfront price, aluminium frequently comes out ahead.

Final Thoughts

So, how long do aluminium doors and windows last?

In most cases, three to four decades or more — making them one of the most durable glazing options available in the UK today.
