Working sash windows and ventilation.
A hot summers night and a sticking sash window are not a good combination. A lot of householders do not realise the top sash should come down, a mirror of the bottom going up. There is a good reason for this – ventilation and air flow. Open you’re lower sash a few inches at the bottom and drop your top sash a few inches from the top. Your notice the difference immediately, especially on those hot summers nights.
If your top sash is stuck as most are then give us a call! We can get it fully operational for you.
