What problems you might experience with your VELUX
There are really only two major reasons for why problems might occur – bad installations and age. We’ll make recommendations for repair or replacement, but some of the issues you might be experiencing include…
- Draughts and wind getting into the room where your VELUX windows are placed.
- Large amounts of condensation and moisture forming on the windows.
- Water leaking around the window, damaging the masonry and walls.
- Stiff and clunky gaskets making the window difficult to open.
- Numerous other issues that can prevent the window from opening.
- Bad insulation resulting in energy wastage.
- Flimsy, deteriorated and aged seals which mean that you can’t shut the window fully.
- General stiff mechanisms meaning your windows don’t shut properly.
- Cracks to the window panes.
- General discolouration to areas of the window caused by sun exposure.
