Signs You Need to Replace Your Windows
Replacement windows can make a huge difference to your home, more than you might think. Here are some signs that it may be time to replace those old windows.
-
Condensation Between the Panes
If there is condensation between the glass panes, it means the seals on your double glazing have 'blown'. This lets moisture get between the panes, which damages the window over time. It also makes your windows less energy-efficient.
-
Draughts Around the Frame
Feeling a cold draught from your window is a sign the weather seals have failed. Defective weather seals allow water and draughts to enter your home and heat to escape. Older windows and modern seals are often not compatible, so it’s best to replace the window when your weather seals go.
-
Difficulty Opening and Closing
Windows often become hard to open or close because of a warped or damaged frame, broken mechanisms or damaged hinges. It could be as serious as a broken lintel. With something like damaged frames and mechanisms, a replacement window is the best option.
-
Damage to Hinges and Handles
Hinges may rust, handles can break or become loose, and glass can crack over time. Older damaged hinges and handles often can’t be replaced because technology has moved on. Replacement windows are the best way to make sure your windows work the way they are supposed to.
-
Damage to Glass
Window glass can get damaged as the years go by. On older properties, single glazing is particularly vulnerable. Damaged double glazed units can be swapped out, but if you go with a different company than the original supplier, there is no guarantee of quality or energy efficiency.

Long-Term Cost Savings with Energy-Efficient Windows
Replacing your windows can actually save you money in the long run by helping increase the energy efficiency of your home. Older windows with poor insulation or broken seals can mean your home is losing heat, leading to more use of your central heating or other expensive heating devices.
Modern windows with double or triple glazing are highly energy-efficient, helping to keep your home at a comfortable temperature all through the year. This means less pressure on your central heating and lower energy bills. While window replacement can be a big expenditure, it could save you money over the long term.

If you need help from Anglian, you can ask for a service visit on our website. Our experts will contact you to schedule a convenient time and date.
Common Double Glazing Issues
Problems with double glazing can include the glass fogging up or showing condensation inside. This can mean the air-tight seal has a leak or has ‘blown’. Likewise, a blown seal can also cause draughts.
Water coming through the window can mean a broken weather seal or a blockage that prevents drainage.
Window Repair vs Replacement
In most cases, replacing a window can be a better option for older or damaged windows. Modern window designs have higher levels of security and energy-efficiency to protect against weather damage and other problems.
Repairs are naturally cheaper than a window replacement, but long-term reliability is increased with new window installation. If your windows are within the guarantee, you may choose to replace the glazing or seals.
What to Expect During Installation
When your replacement windows are ready for installation, we’ll arrange a day when you’re at home so we can fit your new windows.
It’s a good idea to make sure the space around windows is as clear as possible and there are no ornaments or clutter around before installation. Our installers will protect the area and carpets with protective sheets while they carry out their work. Once the work is complete they make good around windows before handing over.
Your Anglian installers will show you how to use your new windows and make sure you’re satisfied with the installation.

Your Questions Answered by us
Many people ask us about the cost of replacing windows. The answer is simple: window sizes differ between properties in the UK, so there is no set price. There are many factors to think about. That's why we say that having a consultation with our team, either in person or online, is the best way to get a quote.
If your double glazing is 20 years old or older, it could be worth replacing. This is especially important if the window is damaged or worn out. By replacing your double glazing, you can save up to 25% on your yearly energy bills.
The lifespan of your windows depends on the material. Well-maintained windows can last for over 20 years. Our white uPVC windows have a BBA accreditation, which means they can last for more than 35 years.
If you can, replace all the windows in your home at once. This will make your home more consistently energy efficient and attractive and increase its value. If that's not possible, replacing all the windows on the front or back of your house is a good alternative.
You can replace the glass in your windows without changing the frame. If you bought your windows from Anglian within the last 15 years, and you have condensation between the glass (which means your sealed units have blown), we'll replace the glass in the window frame. It's covered by our 15-year sealed unit guarantee.
Newly fitted windows can last 30 years or more depending on the material. uPVC is the most durable type of window, though wood and aluminium can also last for several decades.
