When should I replace my double glazing?
Replacing a full house of 8-10 double glazed windows is an investment that will cost several thousand pounds and is a big decision for most people.
We would never recommend for you to replace windows that are in perfectly good condition without any issues. However, it does get to a point when your windows are letting the property down and you would be far better to take the investment rather than making do.
Draughts - the main reason to change windows is that your old ones are letting in considerable draughts and cold which can seriously push up your energy bills.
Double glazing seals can fail so if you can feel cold blowing around the edge of the window it might be time to change them.
Or, your original windows may have been badly fitted with lots of expanding foam around the edges to make up for a poor fit. If this is the case, we would recommend replacing.
Warped frames - older cheap uPVC can warp and discolour leaving windows that look tired and shabby. Warped windows can also cause issues with gaps around the edges letting in cold air.
If your white windows are now the colour of sour cream then it could be time to upgrade.
Condensation - if you have condensation inside the double glazing it indicates the seals on the windows have failed. If you have this problem the only real way to solve it is to replace the windows.
Check with your installer or manufacturer as they might be covered under warranty.
Desiccant - this is where you have bits inside the glass caused by the seals failing.
As with condensation, the only way to solve this permanently is to replace the units with failed seals. Again, check your warranty and guarantee.
