Good News: Minimal Maintenance Required
Secondary glazing is designed to be virtually maintenance-free. Unlike timber windows that need regular repainting, powder-coated aluminium frames require only occasional cleaning to stay looking their best.
Cleaning the Glass
✓ Do
- • Use a soft, lint-free cloth or microfibre
- • Use warm water with mild washing-up liquid
- • Use a squeegee for streak-free finish
- • Clean from top to bottom
- • Clean both sides of secondary glazing panels
✗ Don't
- • Use abrasive cleaners or scourers
- • Use newspaper (can leave residue)
- • Use ammonia-based cleaners on frames
- • Clean in direct strong sunlight (causes streaks)
- • Use pressure washers
Cleaning Between the Panes
The space between your original window and secondary glazing should stay clean due to the sealing, but occasional dust may accumulate.
- For sliding panels: Slide to one side to access and clean the inner face of the original window
- For hinged panels: Open fully for easy access to both surfaces
- For lift-out panels: Remove the panel carefully (two-person job for large panels)
Cleaning the Frames
Powder-coated aluminium frames are extremely durable and resistant to corrosion. Regular cleaning will keep them looking new.
Recommended Cleaning Method
- 1.Wipe frames with a damp soft cloth to remove loose dust
- 2.Mix warm water with a small amount of mild soap or washing-up liquid
- 3.Wipe down all frame surfaces with the solution
- 4.Rinse with clean water and dry with a soft cloth
Avoid Harsh Chemicals
Never use solvents, bleach, or abrasive cleaners on powder-coated frames as they can damage the finish. Avoid ammonia-based products.
Maintaining Moving Parts
Sliding Panels
- Vacuum tracks: Remove dust and debris from sliding tracks regularly
- Lubricate: Apply a light silicone spray to tracks once a year (not WD-40)
- Check rollers: Ensure smooth operation - stiff movement may indicate worn rollers
Hinged & Casement Panels
- Lubricate hinges: Apply light oil to hinge points annually
- Check locks: Ensure locks and stays engage properly
- Adjust stays: Tighten if panels don't stay open at desired position
Seals & Gaskets
- Inspect regularly: Check seals around the perimeter for damage or gaps
- Clean gently: Wipe seals with damp cloth - dirt can affect sealing
- Replace if needed: Worn or damaged seals can be replaced without changing the whole unit
Recommended Maintenance Schedule
| Frequency | Task |
|---|---|
| Monthly | Wipe down glass with damp cloth; quick visual check |
| Quarterly | Thorough clean of glass and frames; check seals; clean tracks |
| Annually | Lubricate all moving parts; deep clean between panes; inspect hardware |
| Every 2-3 years | Professional service and inspection (optional but recommended) |
Common Issues & Solutions
Condensation between panes
Cause: Seal failure allowing moist air between panes
Solution: Check seals for gaps. Minor condensation on cold days is normal; persistent condensation needs professional attention.
Stiff or sticky sliding panels
Cause: Dirt in tracks or worn rollers
Solution: Clean tracks thoroughly and apply silicone lubricant. If problem persists, rollers may need replacement.
Draughts around panel edges
Cause: Worn brush seals or gaskets
Solution: Inspect seals for wear. These can usually be replaced easily and inexpensively.
Lock not engaging properly
Cause: Misalignment or worn mechanism
Solution: Check if frame has moved. Minor adjustments can often be made with a screwdriver. For persistent issues, contact us.
When to Call the Professionals
While most maintenance can be done yourself, some situations need professional attention:
- Cracked or broken glass
- Persistent condensation between panes
- Frame damage or warping
- Mechanism failure (locks, hinges, rollers)
- Significant reduction in acoustic or thermal performance
