Hi all
I had some upvc sliding sash windows installed a few years back and the opening mechanisms on most of them have failed and as such the top sections fall down and the bottom sections wont stay open. I have had several different window repair engineers out but unfortunately none have been able to repair them. The problem I'm having is that none of the engineers were familiar with the type of opening system that the windows are fitted with. They dont have the more standard spring /spiral balances that most upvc sash windows use. The mechanisms as far as I have been able to work out through looking on the internet are known as constant force or coil spring.
Has anyone heard of these or know of any repair engineers who may be able to help? The windows are based in North West London.
many thanks
