Retro fit trickle vents?

Is this possible? We have upvc windows in all but 1 window, all double glazed, but a lot of issues with mould, so I was hoping to fit some to increase ventilation, without replacing the whole windows as they are only a few years old.

I very much doubt this will be possible. You would need a schematic of the windows to see where everything was or you risk weakening the frame and possible hitting something important while drilling holes. The windows with trickle vents are designed for them.

I wouldn't want to try it as it will probably ruin the window.

It can be done, they would probably need to go on the top of an opening sash now though, and instead of routering a slot you would probably be easier drilling a series of holes not only through the plastic but also through any reinforcingto allow the air to circulate. I've done it many times and i have to say it's one of my least favourite jobs. Would leave this one to someone who knows what their doing , too low and you'll hit the glass, too high and you'll come through the top edge of the sash, maybe easier buying a dehumidifier.

I doubt that a few trickle vents would solve your problem of 'a lot of issues with mould'. It is a very complex problem with so many factors impacting on it. I would think a dehumidifier the better option.

Good luck.

I would get myself a dehumidifier rather than start drilling holes and risk ruining the windows (and voiding the warranty if you still have it) A dehumidifier will be far better than trickle vents anyway.
