When should you replace house windows?

It can be tricky to know when your house windows need replacing. However, here is a helpful table to show you what you can do for specific window problems if you don’t want to replace them. If the problems can’t be resolved through these means, you probably need to replace them!

Possible solutions
My window won't open fully or properlyCasement windows: Look into buying replacement parts such as the sash support system or the window operator (handle mechanism). Sometimes the moving parts just need cleaning or lubricating.

Sash windows: If the window has swollen due to heat you can sand or plane the wood panes down to make them slide more easily
My window lets in a chilly draught
Install a draught excluder or replace a faulty one

If you see small cracks, fill them with nail polish
The latches on my window are broken, making me feel unsafe
Buy replacements online and install them yourself or ask a handyman
The glass in my window is foggy
If you are able to remove your window sash, take it to a hardware shop to have the glass or insulated seal replaced
The outside window sill is rotten
The sill can be replaced by itself if the rot has not spread - cut back the rotten wood and replace it with new wood that you can measure from your original cut
One or more panes of glass are broken
You can remove the glass yourself but always wear extensive protective gear and tape the glass to remove it safely

How to install house windows?

Doing home improvement projects DIY style is all the rage these days, and for good reason! You save considerable amounts of money in labor costs and potentially in materials too when you find a good supplier. However there are also significant risks involved with doing home improvement ourselves, and this also applies to windows. They can be easily damaged by a lack of expertise and proper knowledge. While it is possible to install your own house windows, proceed with caution!

For a guide on how you can do this (specifically with relation to uPVC or plastic windows), you can read our article about plastic windows. This short explanation will show you how it’s done, though we recommend doing a lot more research if you’re serious about installing your own windows.

Why is there condensation or fogging on your windows?

Condensation forms when warm damp air meets cooler, drier air. A good example of this is a shower in the bathroom. The difference in temperature makes the warm water in the air condense into liquid on the cold surface. The same thing happens with house windows – if it is warm and humid inside the room, the moisture can condense on a cold window pane.

How can you prevent your house windows from fogging up?

Normally this is avoided by having double glazing, preventing the interior pane of glass from becoming too cold. However with old or damaged windows, the gas between the two panes can leak, allowing cold air in from the outside. This can cause condensation to form (especially in bedrooms at night) on the interior of your window.

Condensation forming on the inside of the window can be avoided by ventilating your room well, avoiding interior humidity. With condensation between the double glazing, you should think of replacing your windows.
