Sick of your rattly, draughty timber windows?

It might be cheaper to rip out your timber windows and replace them with new plastic or aluminium double-glazing units.  However, you will instantly lose the character of your property and it will never look the same.  

Replacing the whole window frame has also been known to cause major disturbances to the structure around your windows, flowing on to create property damage that only appears after the contractor has gone.

On the other hand, keeping original wooden windows maintains and arguably increases the value of your property.

Your timber windows are made of old-growth timber, that has stood the test of time in most cases. 

And with a little TLC and some new upgrades, they can outperform a new window & the frame could to last another 100 years.
