Windows: my advice and more photos
Why we are replaving the windows: 30 years old aluminium window, with condensation, mould and no insulation.
You can clean but it comes back.
We did not realise it was so bad otherwise I would h ave make a lower offer on the house. but what is done is done.
My advice is this:
When you buy a new house, check the windows: if in poor state, mention if when you make your offer and take about £3,000 of asking price for 6 windows.
Secondly, if you have just bought a house and the windows/door need doing, do not wait. You will regret it. Spend the money now. It is worth it. I previoulsy lived in a flat and waited 3 years to change the windows so I was cold in my bathroom for all that time. I did put bubble wrap and cello tape to make sides of sash windows not so drafty.
Someone I know put newspaper around the windows to prevent cold. But dont be cheap, just change the windows, you can see it is not that expensive and will make your home more energy efficient and cosy and healthy.
