Premium Window Installation in Stevenage, Hertfordshire

Stevenage's New Town houses from the 1950s-70s typically have aging casement or picture windows that benefit enormously from replacement. Modern uPVC casement windows dramatically improve thermal performance, security, and appearance. We offer a wide range of styles to suit the various house types.

Stevenage Old Town Conservation Area covers the historic High Street area predating the New Town. North Herts/Stevenage Borough Council requires sympathetic window replacements within this zone. The wider New Town areas have standard Building Regulations requirements.

For Stevenage's predominantly post-war housing, uPVC casement windows offer the best value. A full house replacement for a typical three-bedroom house costs £3,000-£6,000. Many properties still have original single-glazed or aging double-glazed windows, making replacement one of the most impactful home improvements.

Window replacement costs in Stevenage typically range from £300-£2,800 per window, depending on style, material, and specifications. Standard uPVC casement windows cost £300-£500, uPVC sash windows £600-£1,200, timber casement £500-£1,500, and timber sash £1,200-£2,800.
