Did you have to change the frames as well - double glazed would hardly fit in single glazed frames? Did you do them yourself or did you get somebody to do them? We're thinking of doing them (double to double) and don't know whether to go down the DIY route or not.
I'm a craftsman I can do anything I want put my mind to.
I have 60 year old frames in my house.
I measured the inside of the frames then added an inch to that measurement.
Then removed the old glass, routed the frame (15 x25) to fit the new D/glazed units (14mm gauge) leaving 5mm all around for clearence.
When installing the new frames I put in Alexplus sealer (in a tube) to seal the inside of the frame and all around the D/glazed unit (to keep the linseed putty away from the D/glazed joint this is important).
When this is dry used linseed putty to seal the frame in then paint.
Then when painting is finished (2 weeks to a month later to allow putty to harden) I put masking tape on the inside of the open window, put vasiline on that, closed the window then squirt more Alexplus into that joint, smooth it off.
Let it dry for 12 hours open the window, remove the tape close the window and I have a completely air tight window.
It's best to do this during the winter because the wood has expanded to its fullest, if you do this during the summer then you risk the window not closing during the following winter.
If you are looking for a fast job you'd be faster replacing all the frames and glass.
The type of work I do is mainly for people who are trying to keep their old frames which generally look far better than new ones.
This type of work should not be done by the faint hearted.
