SW19 FAQs
How much noise reduction can I expect in SW19?
Homes in Wimbledon typically see 42–48 dB reduction across mainline rail spectrum, depending on window size, façade condition and glass specification. We measure before and after with a calibrated sound-level meter as part of every install.
What glass specification is best for Wimbledon?
For the dominant noise here (Wimbledon mainline & tramlink noise), we recommend 12.8mm asymmetric acoustic laminate with 200mm cavity. In listed buildings or conservation areas we use the same acoustic performance in a discreet slimline frame that satisfies planners.
Do I need planning permission in Merton?
Secondary glazing is internal work and is almost never controlled by planning permission — even in conservation areas. Grade II listed buildings need Listed Building Consent, which we handle with drawings and a heritage statement as part of the quote.
How much does a typical SW19 install cost?
London prices in 2026 start at £450 per window for a small sash and rise to £1,600 for large Georgian sashes with premium acoustic glass. A three-bed Wimbledon flat is usually £3,200–£6,500 fully installed.
