Secondary Glazing cost in Belfast
Secondary glazing fits inside the existing frame rather than replacing it — typically 40–60% cheaper than full replacement and the preferred route in listed buildings.
| Material | Glazing | Estimated price range |
|---|---|---|
| Aluminium | Double | £450 – £1,100 |
Prices are estimates derived from verified Belfast casement baseline data (source: Checkatrade aluminium guide + Origin/Smart tier data) with a secondary glazing-specific multiplier applied. Fully-fitted supply and install including disposal and FENSA/Certass certification.
Belfast note: Northern Ireland labour costs are lower than GB averages; ferry-inflated material costs partially offset savings.
