    Frequently Asked

    Secondary Glazing in Lewisham — Your Questions Answered

    Do I need planning permission for secondary glazing in Lewisham?+
    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 Lewisham properties in conservation areas or Grade II listed buildings. Historic England actively recommends it as a sympathetic upgrade for heritage homes across SE13, SE6.
    How much noise reduction can I expect in Lewisham?+
    Our standard secondary glazing systems reduce external noise by 50–70%. For Lewisham 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 victorian terraces near lewisham high street in Lewisham?+
    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 victorian terraces near lewisham high street, substantial edwardian properties in ladywell, period homes around hither green and other typical Lewisham property styles, preserving sightlines and heritage character.
    How much does secondary glazing cost in Lewisham?+
    Standard configurations for Lewisham 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 Lewisham property?+
    After a free survey, manufacturing takes approximately 4–6 weeks.
