Can I repaint or recoat aluminium frames myself if the finish fades?

We'd recommend having this assessed by a professional rather than DIY — a mismatch in coating type can trap moisture against the metal and cause more harm than the fading itself.

Is uPVC really maintenance-free?

uPVC never needs repainting, but it still needs the same cleaning, drainage-clearing and hardware checks as aluminium — "low-maintenance" refers to the finish, not the moving parts.

How to Maintain Aluminium & uPVC Windows in Malta's Coastal Climate

Quick Answer

Regular cleaning of frames and tracks, checking and lubricating hardware twice a year, keeping drainage channels clear, and inspecting seals for wear are the main maintenance tasks for aluminium and uPVC windows and doors in Malta — more frequent than in milder climates because of salt air and constant sun exposure.

Aluminium and uPVC are both low-maintenance compared to timber, but "low-maintenance" doesn't mean "no maintenance" — especially close to Malta's coast. A few simple habits, done consistently, are what actually gets a system to its full lifespan.

Clean Frames and Glass Regularly

Salt residue and dust build up faster near the coast than most people expect. Wiping down frames with a mild soap solution every few weeks — more often on exposed, sea-facing elevations — stops salt from sitting on the surface long enough to start attacking the finish or hardware.

Keep Drainage Channels and Tracks Clear

Window and sliding door frames have small drainage holes designed to let rainwater escape. Dust, sand and debris can block these over time, which lets water pool and eventually find its way where it shouldn't. Clearing them out during a routine clean takes a few minutes and prevents a much bigger problem later.

Check and Lubricate Hardware Twice a Year

Hinges, rollers, multi-point locking mechanisms and handles all benefit from a light silicone-based lubricant a couple of times a year — never oil-based, which attracts dust. If a handle feels stiffer than it used to, that's usually the first sign it's due.

Inspect Seals and Gaskets Annually

Rubber gaskets around the glass and frame perimeter degrade with UV exposure faster in Malta than in cooler climates. A quick visual check once a year — looking for cracking, shrinkage or gaps — catches a failing seal before it turns into a draught or a fogged double-glazed unit.

What Not to Use

A few common cleaning habits do more harm than good on architectural aluminium and uPVC finishes:

Abrasive scouring pads or powders — they dull powder-coated and painted finishes
Bleach or strong solvent-based cleaners — can degrade gaskets and seals over time
Pressure-washing directly into drainage channels or hardware at close range

As a general guide, sea-facing or highly exposed elevations benefit from cleaning every few weeks, while inland or sheltered elevations can usually go longer between cleans — use visible salt residue or dust build-up as your cue either way.
