Ask most new homeowners what they worry about once they've moved in, and window cleaning is rarely near the top of the list. It usually sits below the garden and working out where everything goes in the garage. But your windows are among the hardest-working parts of your home, letting in light, framing the view, and helping your home perform as it was designed to, every single day. A little care goes a long way towards keeping them doing all three.

If you've read the earlier stories in this series, you'll know windows do a lot of heavy lifting in a Carlisle home: shaping how it looks from the street, and how comfortable it feels to live in through the seasons. Looking after them is the final piece of that story. A simple routine, done a handful of times a year, is enough to protect the investment you made when you chose your windows, and to keep them looking and performing exactly as they did on the day you moved in.

A simple cleaning routine keeps your A&L Windows performing, and looking, their best, for years to come.

A few minutes with your frames

Your window frames do a lot of quiet work. They hold everything in place and take the brunt of Melbourne's weather, season after season, without much fuss. Keeping them in good shape is refreshingly simple: warm water and a mild, pH-neutral detergent, applied with a soft cloth, sponge or natural-bristle brush, is all you need. Rinse thoroughly, then dry with a soft cloth to avoid leaving water marks behind.

How often you'll want to do this depends largely on where you live. As a general guide, homes in the city hold up well with a clean at least every six months. In rural areas, every three months is a better habit, and if you're near the coast, aim for once a month. Salt air is quietly abrasive, and it builds up on frames faster than most people expect.

If your home includes sliding windows, it's worth checking that the drainage holes along the bottom track stay clear while you're cleaning. It only takes a moment, but keeping them free of leaves and debris helps your windows continue to open and close smoothly, the way they were designed to.

It's worth avoiding harsh chemicals or abrasive tools on your frames, too.

Caring for your glass

Glass asks even less of you. A mild, multi-surface glass cleaner works well, or if you'd prefer a simpler option, a mix of one part vinegar to ten parts water does the job just as effectively. What matters more than the product is what you avoid: skip ammonia and alcohol-based cleaners, and steer clear of squeegees, razor blades and steel wool, all of which can mark the glass over time.

Technique makes a difference too. Clean from the top down, and try to avoid working on the glass when it's warm from direct sun, since cleaner dries too quickly on hot glass and leaves streaks behind. Stop wiping just before the glass is completely dry, and you'll get a clean, clear finish every time.

A soft cloth, a mild cleaner and the right technique are all your glass needs to stay clear and streak-free.

A small note on glass aftercare

There's one exception worth noting. Some glass, including Low-E coated glass, has a fine coating on its interior surface that improves thermal performance. Avoid using a squeegee on that surface; everything else about the cleaning process remains the same.

Carlisle homes are built using the full range of glazing options available through A&L Windows, with different glass and coating types specified throughout the home depending on orientation and performance. If you'd like to know exactly what's installed at a particular window, your master drawings are the best place to check.

Knowing when to call in the experts

Most window care is simple enough to fold into your regular home-cleaning routine, but it's worth knowing when to stop and call in help. Windows are a precision-engineered part of your home, and a quick professional check is a far better outcome than a DIY adjustment gone wrong.

A small routine, a lasting return

None of this takes long, and that's really the point. The windows you chose were designed to look considered from the street and perform well from the inside out. A little occasional care is what keeps them doing both, for as long as you live in the home. It's a small routine with a genuine payoff, and another example of how the details you got right early keep paying off long after handover.

Carlisle Homes works closely with long-term partner A&L Windows to make sure your windows are built to perform, and just as easy to look after. For more detail on caring for your windows, explore A&L's product care guide.
