    Frequently Asked

    Secondary Glazing in St John's Wood — Your Questions Answered

    Do I need planning permission for secondary glazing in St John's Wood?+
    In most cases, no. Secondary glazing is installed internally behind your existing windows and is fully reversible, so it typically does not require planning permission or listed building consent — even for St John's Wood properties in conservation areas or Grade II listed buildings. Historic England actively recommends it as a sympathetic upgrade for heritage homes across NW8.
    How much noise reduction can I expect in St John's Wood?+
    Our standard secondary glazing systems reduce external noise by 50–70%. For St John's Wood homes exposed to heavier traffic or urban noise, our 10.8mm acoustic laminate specification delivers up to 80% perceived noise reduction (around 45–50dB), thanks to the wide 100–150mm air cavity between the original window and the new internal pane.
    Will secondary glazing suit a grand victorian detached villas with extensive gardens in St John's Wood?+
    Yes. Every unit is bespoke-manufactured to the exact dimensions of your existing window reveal, with slimline aluminium frames powder-coated in any RAL colour to match original joinery. This makes secondary glazing an ideal fit for grand victorian detached villas with extensive gardens, elegant edwardian mansion flats, properties overlooking regent's park and other typical St John's Wood property styles, preserving sightlines and heritage character.
    How much does secondary glazing cost in St John's Wood?+
    Standard configurations for St John's Wood homes start from around £350–£500 per window. Premium acoustic specifications with 10.8mm laminate glass, heritage detailing, or bespoke finishes typically range from £800–£1,200 per unit. Every quote is prepared after a free on-site survey, so pricing reflects your exact window sizes and specification.
    How long does installation take at a St John's Wood property?+
    After a free survey, manufacturing takes approximately 4–6 weeks. Installation itself is fast and clean — most St John's Wood rooms are completed within a single day, with dust sheets, full site protection, and all waste removed.
