Windows aren’t just frames for your view; they’re essential components of a well-designed home or commercial building. Whether you’re a builder looking to add long-term value to a project or a home renovator aiming for that perfect finish, understanding how to maintain your windows properly is key. It’s not just about keeping them looking fresh; it’s about extending their lifespan, improving energy efficiency, and enhancing the overall comfort of your home.
At Coastal Windows and Doors, we understand this better than most. We’re a family-owned business, proudly crafting custom-made windows and doors for homes and businesses across the Illawarra region since 2004.
Why Window Maintenance Tips Matter
Windows and doors are significant investments, and like any investment, they require care. In fact, maintaining your home’s windows is crucial for both energy efficiency and long-term cost savings, particularly in Australia’s varied climate. Studies show that up to 40% of a home’s heating energy can be lost through inefficient windows, while 87% of summer heat gain enters through them. This means that poorly maintained or outdated windows can have a dramatic impact on your comfort levels and energy bills throughout the year.
Regular maintenance not only protects your windows from wear and tear but also ensures they continue to perform at their best. When properly looked after, your windows will:
- Extend Their Lifespan: A well-maintained window can last for decades, avoiding the need for premature replacement.
- Save You Money: Keeping seals tight and components functioning smoothly helps reduce energy consumption and lower power bills.
- Improve Curb Appeal and Comfort: Clean, undamaged windows enhance both the visual appeal and the indoor comfort of your property.
Whether you’re a builder aiming to deliver lasting value or a homeowner planning a renovation, taking care of your windows is a smart and necessary step.

Key Window Maintenance Tips for Every Homeowner
1. Regular Cleaning: The Foundation of Window Maintenance
The most straightforward yet effective maintenance tip is regular cleaning. Clean glass not only looks great but also allows more natural light to enter your home.
- Use a soft cloth or microfiber towel with mild soap and water to wipe down the glass, frames, and tracks.
- Avoid abrasive pads or harsh chemicals that can scratch or damage finishes.
- For aluminium or timber frames, use cleaning products that are specifically designed for those materials.
2. Inspect for Damage: Spotting Issues Early
Preventative maintenance always starts with inspection. Catching minor issues early can prevent them from escalating into costly problems.
- Check for cracks, warping, or rot in window frames, especially in timber.
- Look out for broken seals, drafts, or foggy panes (a sign of failed double glazing).
- Inspect hardware and mechanisms for signs of wear.
3. Lubricate Moving Parts: Ensuring Smooth Operation
Windows and doors that open and close smoothly are a pleasure to use, and that comes down to regular lubrication.
- Lubricate hinges, locks, and sliding tracks at least once a year.
- Use silicone-based lubricants for best results, as they repel dust and don’t degrade rubber or plastic parts.
4. Maintain and Restore Seals
Weatherstripping and caulking are crucial for keeping your home insulated.
- Check around window frames and sashes for deteriorated or missing seals.
- Replace damaged weatherstripping and recaulk gaps to prevent drafts and water leaks.
- This simple step can dramatically improve energy efficiency and indoor comfort.
5. Clean and Repair Window Screens
Screens keep insects and debris out, but they, too, require care.
- Remove and gently clean screens with soapy water and a soft brush.
- Let them dry completely before reinstalling.
- If you notice holes or tears, consider patching or replacing the screens to maintain full functionality.
6. Seasonal Checks: Adapting Your Window Maintenance Routine
Different seasons place different demands on your windows. A year-round approach ensures consistent performance.
- Pre-Winter: Check seals, locks, and insulation to keep heat in and cold out.
- Post-Winter: Inspect for condensation, mould, and moisture damage.
- Spring/Summer: Deep clean your windows, inspect insect screens, and ensure ventilation is working properly.

While many maintenance tasks can be done at home, there are times when calling in the experts is the smart move:
