French Windows cost in Southampton
French windows (outward-opening paired casements to floor level) cost around 50–70% more than a standard casement due to the larger glass area and threshold detail.
| Material | Glazing | Estimated price range |
|---|---|---|
| uPVC | Double | £950 – £2,400 |
| uPVC | Triple | £1,450 – £3,350 |
| Aluminium | Double | £1,750 – £4,200 |
| Timber | Double | £2,300 – £6,700 |
Prices are estimates derived from verified Southampton casement baseline data (source: Checkatrade (Apr 2025) + HomeOwners Alliance) with a french windows-specific multiplier applied. Fully-fitted supply and install including disposal and FENSA/Certass certification.
Southampton note: South-east cost base pushes labour 10-15% above Midlands; port logistics keep material supply steady.
