Replacement windows in Merstham
Merstham is three places in one parish: the old village round Quality Street, the late-Victorian houses up Rockshaw Road, and the London County Council estate below, finished by the early 1970s.
- Built
- Medieval and later cottages in the village; Rockshaw Road from the 1890s; South Merstham's Victorian and Edwardian terraces; the LCC estate after the war
- Walls
- Merstham stone, brick with burnt headers, render, roughcast, tile-hanging, and timber framing on Quality Street
- Conservation areas
- Merstham Village (1973, extended 1989 and 2009) and Rockshaw Road (1990)
- Article 4
- The 2026 village appraisal records a number of Article 4(1) and 4(2) directions on particular properties; none is proposed for Rockshaw Road

The houses
The stone that built parts of Westminster Abbey and Windsor Castle was quarried here, and you can still see it in the village walls. Quality Street, named after J M Barrie's play, has The Old Forge, a timber-framed listed house with a tile-hung gable, among its cottages. Their windows are small timber casements, and those that are listed need consent for any change.
Rockshaw Road on the hill has Arts and Crafts houses by Paxton Watson from around 1897 to 1905, with leaded casements and Venetian windows. Below the railway, South Merstham's terraces carry sashes, and the post-war estate was built with standard casements. In 2011 the parish had 970 terraced houses, 955 semis, 744 flats and 549 detached.
What gets fitted
On the estate and in South Merstham, chamfered white uPVC casements at £815 to £1,200 for a 1000 x 1200 window are the usual answer. On Rockshaw Road, where there is a conservation area but no Article 4 direction, flush casements suit the Arts and Crafts houses better: £1,100 to £1,950 in uPVC.
In the old village, check whether your house is one of those named in a direction, and whether it is listed, before choosing anything. Where timber is required, a timber flush casement costs £2,000 to £3,800.
