Why now is the time for replacement double glazing

Falcon Installations explains why winter is the ideal time to plan your double glazing upgrades – and how replacing older windows now can make next year’s colder months far more comfortable

It can be very difficult to make your home feel warm during the colder months, and this is often more apparent in the festive season when you’re at home more to assess the cold air, condensation and mould. But winter is the ideal time to plan and action changes to your home, so they can be carried out in spring. 

If you’ve been thinking about upgrading your double glazing, spring is one of the best times to act. Not only does the weather help the installation go smoothly, but it also gives your home a fresh start for the rest of the year. Replacement double glazed windows could be the ideal solution to many of your problems, and there’s no better time to have them installed. Add double glazed windows to your 2026 checklist now, to make your home more comfortable and enjoyable for years to come.

Winter weather: The perfect indicator it’s time to replace your double glazing

Over the last few months, you might have noticed a few draughts creeping into your home, and this could be due to ageing or faulty windows. These draughts are often caused by deteriorating seals around the window frame, which naturally break down over time. This allows cold air to seep in and warm air to escape, creating uncomfortable rooms and forcing your heating system to work harder.

This is also a sign that your windows are no longer as thermally efficient as they once were. If your home feels colder than usual or you’ve noticed your energy bills rising, it might be worth considering new double glazing. Investing in replacement double glazed windows now can help ensure you’re warm and ready to take on whatever next winter has in store.

For those with older installations, upgrading to aluminium double-glazed windows is also an option. Aluminium offers a sleek, modern look with excellent durability, making it a popular choice for homeowners wanting long-term performance as well as improved insulation.

The condensation question

Condensation is another issue that many homeowners find themselves dealing with throughout winter. It is most common first thing in the morning when outdoor temperatures have been significantly lower overnight. When the warm, moist air inside your home meets cold glass, water droplets begin to form.

This might seem like a minor irritation, but left unchecked, it can lead to more serious problems such as water damage to windowsills, frames and surrounding plaster. Excess moisture can also lead to mould and mildew growth, which can impact both your health and the overall condition of your home. Any water that gathers around the mechanisms can also affect how easily your windows open, close and lock.

Upgrading to modern double glazing is one of the most effective solutions for reducing condensation. Newer systems provide better thermal insulation, which means the inner pane of glass stays much warmer compared to older glazing. Because the temperature difference between the pane and indoor air is smaller, condensation is much less likely to form.

The spring season – time to bounce back

If the winter has highlighted issues in your home, now is the ideal time to plan your replacement double glazed windows project. Spring naturally brings a sense of renewal, and many homeowners take this opportunity to freshen things up and improve comfort before the next cold season arrives. The milder weather also makes installation easier, with fewer disruptions from rain or freezing temperatures.

Spring installations are also more comfortable for households, as you avoid the heat loss that can come from replacing windows during the coldest months. Whether you choose uPVC or aluminium double-glazed windows, the process is smoother and more efficient at this time of year.

It’s also worth knowing what to expect when planning any window upgrades. When arranging new double-glazed windows in South Wales, choosing a reliable installer ensures your windows are fitted correctly, perform well and meet the latest energy standards.
