How to Maintain Aluminium Windows for Long-Lasting Use in Kenya

Aluminium windows have become a favourite choice for homeowners, contractors, and developers across Kenya. They are stylish, durable, weather-resistant, and perfect for both modern homes and commercial buildings. But like every long-term investment, proper care is what keeps them performing beautifully for years.

Whether you have sliding windows, casement windows, tilt-and-turn models, or modern black aluminium designs, the good news is that aluminium windows are low-maintenance. With a simple routine, you can prevent wear, preserve their beauty, and avoid unnecessary repairs in the future.

Below is a practical guide to maintaining aluminium windows for long-lasting use, featuring expert insights from industry leaders like TSL Industries.

1. Clean the Aluminium Frames Regularly

Dust, moisture, and coastal air (especially in places like Mombasa) can settle on your frames, causing dullness over time. Cleaning the frame every 1–2 months helps keep them fresh and corrosion-free.

How to clean them

Use mild soapy water and a soft cloth.

Avoid steel wool or abrasive cleaners they scratch the surface.

Rinse with clean water and wipe dry to prevent water spots.

If your windows have a wooden finish, regular gentle cleaning helps maintain the colour and texture.

2. Keep the Glass Sparkling Clear

Clean glass not only enhances visibility but also keeps your home looking bright and elegant.

Tips for glass maintenance

Use a soft microfiber cloth.

Apply a glass cleaner or a vinegar-water mix.

Avoid harsh chemicals that can damage tint or laminated layers.

For larger windows or balcony glazing, a squeegee is your best friend.

3. Lubricate Moving Parts

Sliding windows, hinges, handles, and locks work smoothly when properly lubricated. This prevents squeaking, jamming, or stiffness.

What to do

Apply silicone spray or light machine oil every 3–6 months.

Wipe away dust before lubricating.

Avoid heavy grease — it traps dirt.

If your aluminium windows use a single or double roller system, lubrication greatly increases the lifespan of the wheels.

4. Check and Clean the Drainage Channels

Most aluminium window systems come with built-in drainage holes that remove water during rain. If they are blocked, water can accumulate and damage seals.

Maintenance steps

Use a brush or blower to remove debris.

Test the drainage by pouring water and observing flow.

Clear any blockages immediately.

This step is especially important in areas with heavy rain like Western and Central Kenya.

5. Inspect the Rubber Seals and Gaskets

Rubber seals are essential for insulation — they keep out dust, noise, and moisture. Over time, they may dry, crack, or loosen.

What to check

Look for gaps or hardened rubber.

Replace worn-out seals to maintain airtight performance.

Ensure the gasket remains flexible.

High-quality windows from companies like TSL Industries come with durable, long-lasting seals, but periodic inspection is still important.

6. Keep Tracks and Frames Free from Dirt

For sliding windows, dirt buildup along the tracks causes friction and eventually damages rollers.

How to maintain tracks

Vacuum or brush out debris.

Wipe with a damp cloth.

Lubricate lightly (avoid excess oil).

Clean tracks ensure effortless opening and closing.

7. Repaint or Refinish Only When Necessary

Most aluminium windows come with powder-coated, anodized, or wood-grain finishes that hardly need repainting.

But if the surface ever fades or chips

What to do:

Call a professional to refinish or repaint using the correct coating.

Avoid DIY repainting — aluminium requires special treatment.

8. Avoid Excessive Force

If a window feels stuck, do not force it open. This can bend the frame or damage the rollers.

Instead:

Check for dirt in tracks.

See if lubrication is needed.

Request professional repair if necessary.

9. Clean the Window Screens (If Installed)

Mosquito screens collect dust fast, especially in urban areas like Nairobi or industrial locations.

Maintenance routine

Remove the screen carefully.

Wash with mild soap and water.

Dry before reattaching.

This helps maintain airflow and hygiene.

Benefits of Maintaining Your Aluminium Windows

Proper care ensures:

Longer lifespan (can last 20–30+ years)

Smooth operation all year round

Better energy efficiency

Clean, modern appearance

Reduced repair and replacement costs

Enhanced security

When maintained well, aluminium windows remain as impressive as the day they were installed.

Why Professional Maintenance Matters

For repairs, seal replacements, large window adjustments, or roller replacements, always hire a qualified technician.

Companies like TSL Industries, with over 13 years of experience in aluminium and glass fabrication, offer expert servicing, including:

Aluinium windows & doors installation

Repair and maintenance

Fabrication of sliding, casement, tilt-turn, and curtain wall systems

This ensures your windows remain structurally sound and aesthetically appealing.

Conclusion

Aluminium windows are one of the best investments you can make for your home or commercial building in Kenya. With the right maintenance routine — simple cleaning, lubrication, inspections, and professional care when needed — you can enjoy their sleek look, strength, and smooth performance for decades.

Whether you’re building, upgrading, or maintaining your space, keep your aluminium windows in top shape to protect your investment.
