Frequently asked questions
Do I need Listed Building Consent for sash work in Kemptown or Brunswick? If the building is listed, yes, for any change inside or outside. Even where the building is unlisted, Article 4 directions across parts of Brunswick and Kemptown catch every window change. Brighton and Hove City Council conservation officers commonly approve slim double-glazed replicas but refuse full 24 mm units on street elevations.
Can I keep the original box and just replace the sashes? Often the box is worth saving. Refurbishing the box, fitting new draught-proofed sashes with slim units and adding modern balances typically runs 30 to 40 per cent cheaper than a full box replacement.
What acoustic performance do slim units deliver on the seafront? Slim units alone cut noise by around 25 dB. For seafront elevations we usually pair slim glazing with a secondary unit to reach 40 dB or higher.
