Aluminium Window & Door Maintenance UAE: The Annual Service Checklist

Why UAE maintenance schedules differ from European guidance

The maintenance intervals recommended by European aluminium window manufacturers are designed for temperate climates with moderate UV, occasional frost and seasonal rain. In the UAE, the operating conditions are categorically different: average summer surface temperatures on south and west-facing frames exceed 60°C, UV radiation at Dubai's latitude is among the highest in the world, and sand abrasion runs year-round rather than seasonally. If you follow the manufacturer's standard 2-year maintenance interval, you will be replacing hardware and sealants years earlier than necessary.

The guidance below is based on Swiftrooms' fifteen years of UAE service experience and reflects what actually degrades first, fastest, in this specific climate. For manufacturer warranty to remain valid, the intervals and methods below should be observed from year one.

Every month: track cleaning

The drainage channels at the bottom of each window and door frame must be cleared of sand, dust and debris monthly. In the UAE, fine sand accumulates rapidly in these channels — if it compacts, water from cleaning or rain cannot drain and sits in the rebate, accelerating sealant degradation and hardware corrosion. Use a soft-bristle brush or a vacuum to clear each drainage port. Rinse with clean water from a hose or bottle.

For ground-floor frames in sandy environments or near landscaping, this monthly check is non-negotiable. For upper-floor frames in enclosed buildings, quarterly may suffice.

Every 6 months: hardware lubrication

All moving hardware — hinges, multi-point locking bars (espagnolettes), handle mechanisms, tilt-and-turn gearboxes, and lift-and-slide rollers — should be lubricated every 6 months. Use a PTFE-based dry lubricant spray or a light machine oil (such as 3-in-1). Avoid WD-40 for ongoing lubrication — it is a displacing fluid rather than a lubricant, and will dry out within weeks, leaving hardware unprotected.

For lift-and-slide door systems, the sill track rollers and the anti-lift blocks should be cleaned of any grit before lubrication. Grit on the rollers causes premature wear to the track. Apply lubricant to each roller, then open and close the door twice to distribute it evenly.

Bi-fold door hinges have a tension adjustment screw — check that panels align correctly when folded. Misalignment causes uneven wear on the gaskets at the panel-to-panel seal. Adjustments can be made with a hex key without specialist tools.

Annual: sealant inspection and frame cleaning

The silicone sealant at the glazing bead (where the glass meets the frame) and at the perimeter of each frame (where it meets the wall) is the first component to degrade in the UAE climate. UV and thermal cycling cause silicone to harden, crack and pull away from the substrate. Inspect these lines annually — press the sealant with your finger: it should be flexible and springy. Hard, cracked, or visibly pulled-away sealant should be removed and replaced. This is the single most important maintenance task for preventing water ingress.

Powdercoated aluminium frames should be washed annually with warm water and a pH-neutral detergent. Do not use alkaline cleaners, abrasive sponges or solvents on powder-coated surfaces — these damage the film. Rinse thoroughly after washing. For anodised aluminium, the same applies: neutral detergent and clean water only.

Inspect the weep holes (small slots at the base of each frame) to confirm they are clear. On sliding doors, confirm the sill gasket is seated correctly and not compressed flat — a permanently compressed sill gasket provides no weather sealing.

Annual: glass inspection

Inspect the glass units annually for edge seal failure — this appears as a milky or fogged appearance in the edge zone of a double-glazed unit, sometimes with condensation forming between the panes. A failed unit seal does not always require immediate replacement, but it will progressively worsen and eventually impair the thermal performance of the unit. Failed seals should be replaced within 1–2 seasons.

Solar control glass coatings are on the inner surface of the outer pane in double-glazed units — they should never be cleaned with abrasive materials. For heavily soiled glass, use a glass cleaner and a microfibre cloth. Hard water deposits (calcium scale from UAE tap water used in window cleaning) should be removed with a dilute white vinegar solution before they etch the glass surface.

When to call a professional

Hardware replacement (hinges, locks, espagnolettes, roller assemblies) should be carried out by an authorised installer or service engineer — incorrect installation can void manufacturer warranties and may compromise security. If a handle is difficult to turn, a lock does not engage properly, or a sash no longer seals correctly when closed, book a service visit rather than forcing the mechanism.

Swiftrooms offers an annual service programme for all systems we have installed. The programme covers hardware adjustment, lubrication, sealant inspection, drainage clearing and a full operation check — scheduled to coincide with the beginning of the September–November cool season, when natural ventilation use increases significantly.
