When windows become worn or damaged, it affects their energy performance and the security of your home. Replacement windows from Anglian make your home more secure, energy efficient, and are a great way to enhance its visual appeal. When you notice the following signs, contact us to book a visual consultation and free no-obligation quote.

Signs you need to replace your windows

  1. Condensation between the panes

    Condensation between the glass means your double glazing seals have 'blown'. This allows the gas to escape and decreases the thermal efficiency of the window. Left unchecked, the moisture leads to further problems that could also require window replacements.

  2. Mould inside the windows

    When glazing seals degrade, air and moisture cause condensation between the glass, which can lead to mould. Mould damages windows, particularly timber frames, and puts your health at risk over time.

  3. Draughts around the frame

    Feeling a cold draught from your window is a sign the weather seals need replacing. Defective weather seals allow water and draughts to enter your home and heat to escape.

  4. Difficulty opening and closing windows

    Windows that become difficult to open and close are often caused by damaged hinges, handles, or frames. Though they can also be a result of debris obstructing the window from closing.

  5. Damage to hinges, handles and glass

    Over time, window hinges may rust, handles can break or become loose and glass can crack. These problems affect security, lower energy performance and allow weather to damage your home.

Replacement Window FAQ's

How do you know when it's time to replace windows?
There are several clear signs that your windows need replacing, such as feeling an outdoor draught, or having trouble opening, closing or locking your windows. If you notice condensation and moisture gathering between the glass panes, this means that your double glazing is no longer airtight, and indicates you need a window glass replacement.
How often should you replace the windows in your house?
While this depends on the material your windows are made from, properly maintained windows should last upwards of two decades. Anglian window frames are all covered by our 10-year guarantee, while the glass itself is covered by our 15-year sealed glass unit guarantee. Our white uPVC casement and tilt and turn styles hold a BBA accreditation, which means they can last in excess of 35 years.
Should I replace all my windows at once?
If you have the budget to replace all the windows in your home at once, you can significantly increase the energy efficiency of your property, as well as kerb appeal and even property value. This solution might not be affordable, in which case even replacing one faulty window with an Anglian frame can improve the heat retention of your home.
What are the best replacement windows?
The best all-around replacement windows are those made from uPVC. This is because they balance cost with high energy ratings. White uPVC replacement windows from Anglian are BBA rated, which means they can last up to 35 years if well maintained. Find out more about the different materials available in our window material guide.
Can I just replace the glass in my windows?
It’s possible to replace the glass in your windows without changing the frame – this is why we guarantee sealed glass units separately for 15 years, while our window frames are covered by a 10-year guarantee. Anglian can replace the glass in a window frame, presuming it was purchased from them initially and it is still under guarantee.
How long does it take to replace one window?
If your window frame is still in good condition but you’re having problems with the glass, such as condensation between the panes, it’s more cost effective to replace the glass rather than the whole window. Replacing just the glass will still offer benefits, such as reduced heat loss and improved energy efficiency. Anglian replaces glass within the 10-year guarantee if we installed it originally, however we also offer competitive finance options to help customers afford full window replacement.
Is it cheaper to replace glass or whole window?
If your window frame is still in good condition but you’re having problems with the glass, such as condensation between the panes, it’s more cost effective to replace the glass rather than the whole window. Replacing just the glass will still offer benefits, such as reduced heat loss and improved energy efficiency. Anglian replaces glass within the 10-year guarantee if we installed it originally, however we also offer competitive finance options to help customers afford full window replacement.
