How long do new uPVC windows last?

uPVC windows can last anywhere from 10 to 35 years. However, the lifespan will vary depending on several factors, including the quality of the materials, the installation standard, and the maintenance level.
uPVC comes in different grades, and cheaper windows may be lower grade and constructed with thinner profiles. Higher-priced windows should have better thermal properties and more robust fittings and will last longer.
The standard of window installation is also important in estimating how long a window will last. Poorly installed windows are more likely to leak, warp or crack. Check that your installer is FENSA registered to ensure the best quality installation.
uPVC windows are known for low maintenance, but that doesn't mean you can ignore them once installed. Regular cleaning will prevent damage over time and ensure your windows last as long as possible.

Quality affects how long uPVC windows last

The quality of the materials used to make uPVC windows will significantly impact their lifespan. uPVC comes in different grades. General grade uPVC is the cheapest and easiest to work with. It is not as fire retardant as higher grades or impact-resistant. High-quality uPVC windows are made from denser plastic, are more durable, more resistant to weathering and damage and have greater resistance to fire.
Of course, the grade of uPVC plastic is just one factor to consider when choosing a window. Other factors to consider include the type of glass used, the window's energy efficiency rating, and the warranty details. You may also consider the standard of hinges, handles and locks. The better the quality, the longer they will last, but you will have to pay more.

Good installation prolongs the lifespan

The quality of the installation is hugely important for the lifespan of uPVC windows. Windows that are installed incorrectly are more likely to leak, warp, or crack. If you're considering replacing your uPVC windows, get quotes from several companies before making a final decision. You should also choose a company such as Select Window Systems that offers a product and service warranty. FENSA is a government-authorised scheme that monitors building regulation compliance for replacement windows and doors. FENSA-approved installers are assessed regularly to ensure high standards are continually maintained. Your window installer should provide you with a FENSA certificate to show it complies with Building Regulations, Is registered with the local council and is backed by an insurance guarantee.

Looking after your uPVC window

UPVC windows will last longer if they are correctly maintained. This includes cleaning the windows regularly and keeping them free of debris. It will help to remove dirt, debris, and pollen, which can damage the window over time. Inspecting your windows regularly for any signs of damage, such as cracks, chips, or leaks, is also a good idea. If you find any damage, have it repaired or replaced as soon as possible.
Check on the weather seal for any cracks or holes. The seal keeps out moisture and air, which can damage your windows. Avoid using harsh chemicals when cleaning. Additives such as bleach or ammonia can damage the finish on your window and reduce its lifespan. Always use mild, soapy water with a soft micro-fibre cloth to keep your windows clean.

When to replace a uPVC window

Some signs will signal when it's time to replace your uPVC windows. If you can feel cold air coming in through your windows or see water dripping down the outside, it's a sign that they're not adequately insulated. This can lead to higher energy bills and uncomfortable living conditions.
If your windows are cracked, chipped, or otherwise damaged, they're not as energy-efficient as they could be. They may also be more likely to break in a storm and need replacement.
UPVC windows typically last 20-30 years, longer if you look after them properly. But if your windows are older than that, they may be starting to show their age. New uPVC windows will almost certainly increase your home's energy efficiency and keep your home warmer in the winter and cooler in the summer. New uPVC windows can give your home a fresh new look. They can also come with various features, such as energy-efficient glass, to improve your home's comfort and value.
