Are you wondering when to replace the windows in your home? It’s a common question among property owners looking to improve energy efficiency and indoor comfort. While windows can last for many years, their performance and appearance tend to deteriorate over time. That’s why it’s important to recognize the right moment for replacement and understand the benefits it brings.
How often should windows be replaced?
There’s no one-size-fits-all answer to how often windows should be replaced, as it depends on the type of window, the quality of installation, the level of maintenance, and how frequently they’re used.
Generally speaking:
- PVC windows last around 20–30 years
- Aluminium windows can last 40–50 years
Reasons for replacement can include:
- Difficulty opening or closing windows
- Drafts or moisture appearing around the frames
- Visible damage, such as cracked glass
- Poor insulation and energy loss
- Desire for improved thermal and acoustic performance
- Updating the visual appearance to match a new interior style
How to prepare for window replacement?
Proper preparation is key to ensuring the process goes smoothly. Here are a few important steps:
Choose the right type of window. If you’re unsure, consult with a specialist who can recommend the best solution for your home.
Take precise measurements of the window openings.
Prepare the surrounding area. Remove window treatments like curtains, blinds, or rods, and clear the window sills. Move furniture away from the windows and protect the floor and furnishings with dust sheets.
The best time to replace windows is during warmer months — spring, summer, or early autumn — for a faster and more comfortable installation process.
Step-by-step: the window replacement process
Removing the old windows
The process begins with the removal of the old sashes, followed by careful dismantling of the frame. This can take anywhere from several minutes to a few hours depending on window size and structure. MIROX also offers old window disposal services.
Installing the new windows
There are different installation methods: basic installation, warm installation (with sealing tapes), and installation outside the wall face. The warm installation method has become the modern standard, as it helps prevent thermal bridges and improves insulation thanks to special sealing tapes and materials.
Finishing the window recess
Once installed, any gaps or damaged surfaces around the windows are plastered and smoothed out for both functionality and aesthetics.
Adjustment and cleanup
After installation, the fitters adjust the windows to ensure smooth opening and closing. They provide guidance on maintenance and regulation. The team also takes care of cleanup and can remove all debris and old components, leaving the site clean and tidy.
Benefits of new windows
Energy savings
Modern windows reduce heat loss and help lower heating bills, making your home more energy-efficient.
Increased comfort
Better thermal and sound insulation eliminates drafts and outside noise, enhancing the indoor living experience.
Improved security
New windows are often equipped with advanced security features such as reinforced hardware, locking handles, or magnetic sensors to better protect against break-ins.
Higher property value
In addition to visual appeal, replacing windows increases your home’s market value — a great advantage if you plan to sell.
