Secondary glazing from Selectaglaze or City Sound Glazing?

[Margot2017]

I really dislike the look of secondary glazing, but we have just bought a flat with crittal windows that let in every gust of air and don't block any noise. We're refurbishing now and have decided to replace the existing secondary glazing (which looks awful). I'm considering both companies, but any other suggestions are also very welcome. We're in London.

Hi. I am in exactly the same position - which to choose: SelectaGlaze or City Sound? I ended up with these two after extensive research. But which? Can you tell me who you eventually chose, and what your experience was? Thanks!

Can highly recommend cricklewood glass.
