Secondary Glazing FAQs

How much does secondary glazing cost?

Secondary glazing usually starts from around £350 per window supplied and fitted, which is typically less than full window replacement. We confirm your price after a free survey.

Does secondary glazing reduce noise?

Yes — the wider air gap between the existing and secondary pane is very effective at reducing external noise, which is why it is popular near busy roads, railways and flight paths.

Is secondary glazing as good as double glazing?

For noise and added insulation it performs very well, and it has the advantage of keeping your original windows — important for listed and conservation properties where replacement is not permitted.

Can I have secondary glazing on listed buildings?

Usually yes — because it is reversible and does not alter the original window, secondary glazing is often acceptable where replacement double glazing is not, though we always check local requirements first.
