How to Maintain Aluminium Windows & Doors: A Practical Guide

Aluminium windows and doors are low-maintenance by nature — but "low maintenance" doesn't mean "no maintenance." A small amount of regular care goes a long way in keeping them operating smoothly and looking great for 20 years or more.

This guide covers everything from routine cleaning to hardware care, so you know exactly what to do and how often.

Cleaning the Aluminium Frame

How often: Every 1–3 months, or when visibly dirty.

What to use:

• Warm water with mild dish soap or a pH-neutral household cleaner
• A soft cloth or sponge
• A soft-bristle brush for track channels

What to avoid:

• Abrasive cleaners or scouring pads — these scratch the powder-coat finish
• Steel wool
• Bleach or solvent-based cleaners
• High-pressure water jets directly onto seals and joints

Method: Wipe the frame down with a damp soapy cloth, then rinse with clean water and dry with a soft cloth. Pay attention to corners and joints where dirt accumulates.

Cleaning the Glass

Use a standard glass cleaner or a diluted white vinegar solution. Wipe with a lint-free microfibre cloth in overlapping strokes for a streak-free finish.

For double-glazed units: if you notice condensation between the glass panes (rather than on the surface), this indicates a failed seal in the IGU unit. Contact us for an assessment — the glass unit will need to be replaced.

Cleaning the Track Channels

Track channels on sliding and folding systems collect dust, debris, and insects over time. Blocked tracks cause increased friction and can accelerate wear on the rollers.

How often: Every 3–6 months.

Method:

1. Use a soft brush or vacuum to remove loose debris
2. Wipe the channel with a damp cloth
3. Dry thoroughly
4. Apply a small amount of silicone-based lubricant along the track

Lubricating Hardware

Hinges, rollers, handles, and locking mechanisms all benefit from periodic lubrication.

How often: Every 6–12 months, or when you notice stiffness or unusual noise.

What to use: Silicone-based spray lubricant. Apply sparingly — a little goes a long way.

What NOT to use:

• WD-40 or petroleum-based oils — these attract dust, leave residue on powder-coated surfaces, and break down rubber seals over time
• Thick grease — clogs the mechanism

Method: Apply silicone spray to the moving parts of hinges, the roller wheels on sliding doors, and the locking bolt mechanism. Operate the door or window through its full range of motion a few times to distribute the lubricant evenly.

Inspecting and Replacing Weather Seals

The rubber or brush seals around the perimeter of your windows and doors serve two functions: keeping water out and improving energy efficiency. Over time, seals can harden, crack, or compress permanently.

Signs a seal needs replacing:

• Visible cracking or gaps in the rubber
• Drafts felt around the closed frame
• Water ingress during rain

Weather seals are inexpensive and straightforward to replace. Contact us for a service visit or purchase replacement seals from our showroom.

Checking Fixings and Handles

Periodically check that:

• All handle screws are tight (use a screwdriver — don't overtighten)
• Window stays and restrictors are secure
• No visible corrosion on exposed fasteners (rare with quality hardware, but worth checking in coastal areas)

What to Do If Something Isn't Working Right

Stiff or heavy to operate: Usually solved by cleaning the track and lubricating the rollers. If it persists, the rollers may need adjustment or replacement.

Door or window won't close flush: Aluminium frames can shift very slightly over time with building movement. This is usually a simple adjustment to the hinges or the locking keep. Don't force a misaligned door — call us for a service visit.

Lock difficult to engage: Often just needs lubrication. If the bolt doesn't align with the keep, the strike plate may need repositioning.

Within warranty: All the above are covered by our 10-year warranty if caused by a manufacturing or workmanship issue. Contact us and we'll arrange a free inspection.

Summary: Maintenance Schedule

| Task | Frequency | |---|---| | Wipe down frames | Every 1–3 months | | Clean glass | Monthly or as needed | | Clean track channels | Every 3–6 months | | Lubricate hardware | Every 6–12 months | | Inspect seals | Annually | | Check fixings | Annually |

Following this simple schedule takes less than an hour per year and will keep your aluminium windows and doors in excellent condition for decades.
