Jacqui’s familiarity with NK Windows’ high-performance window and door system from her previous residence influenced her decision to upgrade the windows of her 1999 3-bedroom Rockcote house. The original aluminum single-glazed windows were prone to condensation and draughts, posing security concerns after a break-in. However, since the installation, Jacqui and Glenn have noticed significant improvements in warmth and security, with the house maintaining a consistent temperature throughout. Jacqui’s careful monitoring revealed a 3-4°C increase in temperature, despite setting the heat pump thermostat 2 degrees lower, demonstrating the energy-efficient benefits of uPVC windows and doors.
In January 2015, Annie and Alec embarked on the extensive task of upgrading the windows and doors of their sprawling two-storey early 1900s home. They opted for NK Windows due to its esteemed reputation, local manufacturing, and the assurance of having in-house installers rather than contractors. This decision was reinforced during the second phase of their renovation in August 2016.
The original joinery posed numerous challenges, with draughts and sticking doors requiring considerable effort to close. However, Annie and Alec found that the new windows and doors seamlessly integrated with the house’s aesthetic while providing enhanced functionality, exceptional sealing, and a notable improvement in comfort. They were particularly impressed by NK Windows’ installation team, who consistently displayed politeness and maintained cleanliness—a stark contrast to their experiences with other tradespeople. Additionally, Annie and Alec valued the secure ventilation feature of the German-designed and manufactured Tilt & Turn window hardware, allowing them to leave their windows tilted with confidence even when away from home.
