Maintenance means preserving your glazing system before problems emerge. When done well, it keeps your windows and doors operating smoothly, retains insulation performance, and extends service life. This guide applies to Australia’s climate, materials, and supply ecosystem.
Origins & Importance
Routine upkeep of glass, seals and frames has long been part of Australian household culture. Early Queenslanders would oil window tracks, repaint timber frames, and re-putty glass panels routinely to combat sun, wind, termites, and moisture. Today, modern materials reduce demands — but neglect still leads to drafts, leaks, fogging (in double glazing) or frame decay.
Types of Maintenance
DIY Routine Care
- Tracks & sills: Remove debris, vacuum, then wipe with mild soapy water. Helps sliding doors/windows stay free-flowing.
- Rollers & hinges: Use silicone spray (not grease) to keep mechanisms moving without attracting grime.
- Seal & gasket inspection: Feel edges for drafts; check for signs of brittleness or shrinkage.
- Glass cleaning: Use non-abrasive cloth and ammonia-free glass cleaners, especially for coated or Low-E glass.
Quick tip: in coastal or dusty areas, schedule quarterly reviews rather than annual only.
General & Preventive Maintenance
- Seal replacement: Worn seals undermine thermal and acoustic performance. Replace before full failure.
- Scratch correction: Minor scratches may be polished out; deep ones usually require replacement glazing.
- Re-puttying: For traditional timber windows, remove failing putty, clean the rabbet, apply fresh glazing putty, then paint.
- Drainage/weep hole clearing: Ensure water paths remain open so moisture doesn’t accumulate inside frames.
Frame Maintenance
- Timber frames: Repaint or restain every 5–7 years. Sand and seal peeling or cracked areas. Inspect for rot or termite damage.
- Aluminium frames: Clean with mild detergent to remove salt spray or pollutants. Check for corrosion or pitting.
- uPVC frames: Low maintenance, but still clean regularly; monitor for warping or seal damage.
- Hardware: Tighten screws and apply silicone lubricant to locks, handles, and stays.
Sealing & Glazing Seal Maintenance
- Perimeter caulking: Inspect for cracks or gaps around glass-to-frame and frame-to-wall joints; reseal with neutral-cure silicone.
- Weatherstripping: Renew strips where compressed or cracked.
- IGU (double-glazed unit) seals: Once failed, moisture between panes usually requires full IGU replacement.
- Moisture control: Address ventilation and sealing immediately if condensation appears inside glazing.
