Can you work on Grade I listed buildings?

Yes — we've installed in Grade I, II* and II listed buildings. Our approach prioritises reversibility and minimal intervention, working closely with conservation officers and specialist heritage consultants.

Do you handle stained-glass restoration?

We coordinate stained-glass restoration with specialist conservators, supplying protective external glazing or secondary glazing systems that preserve the original stained glass from impact damage and weather.

How long does listed-building consent take?

Listed-building consent typically takes 8-12 weeks. Secondary glazing is usually permitted without consent because it doesn't alter the external fabric — we confirm this with your conservation officer at survey stage.

Can secondary glazing match the appearance of original sash windows?

Yes — our secondary units are installed internally behind original windows, with slim aluminium frames in matching colours. Almost invisible from the street, fully compliant with conservation requirements.

Heritage & Listed Building Glazing | Churches, Conservation

S&K Glazing has worked with parish churches, cathedrals, mosques, temples, listed manor houses, and conservation-area properties across the UK. Our specialisms include slimline secondary glazing for thermal and acoustic upgrades without altering original windows, stained-glass repair coordination, bespoke timber-window manufacture to match original profiles, and lead-light restoration.
