UPVC window lock won't open!

Hi all,

I've recently moved in to a house and discovered that one of the upvc windows doesn't open. When I unlock it and lift the handle, the mechanism is only opening one side of the window. Obviously the window is shut so I can't get at the mechanism to do anything about it.

I've called the company who installed the windows and they wanted to charge me £80 to transfer the guarantee to my name. Seems a bit steep to me!

Does anybody out there have any suggestions?

Cheers
Andrew

I've had a couple of problems with my uvpc windows locking mechanism.
One was the handle had no effect whatsoever due to the square spindle moving forward and out of engagement, also unable to open window when handle was effective.
I found it easy to move handle although one of the fixing screws is hidden behind foil.
I found handle moved through 90 degrees only and restricts movement of sliding bar, but to get a bit more I substituted the handle with square rod and spanner.
I also found my opening frame is not perfectly square, mine are hinged at the top, but the bottom had moved across to the right and made the locking buttons deeper in engagement in the locking slots.
You may find you have similar problem and beside opening handle you may have to strain frame a little for it to open.

Take the window handle off, then you should see a square splindle hole which sometime you can twist it round very carefully with another square splindle then check on the back of the window handle splindle for damaged

I'll give that a go later today. Cheers.

Appreciate the help.

and the result was ?
