About Our Service

Our double-glazed windows are designed to reduce energy bills by improving insulation, keeping your home warm in winter and cool in summer. With over 20 years of experience in Bicester, we provide tailored double-glazing solutions that suit the town’s varied architectural styles. Bicester features a mix of Victorian and Georgian homes, known for their sash windows and period charm, alongside modern eco-friendly developments as part of its Garden Town status.

Given Bicester’s climate—cool, damp winters and mild summers—energy efficiency is vital. Our A-rated double glazing, featuring 28mm argon-filled units with warm-edge spacers, provides superior insulation. We also comply with local building codes to ensure every installation fits seamlessly within Bicester’s heritage or contemporary homes. Whether you live in a historic property or a modern build, our high-quality, eco-friendly windows maintain the aesthetic integrity of your home while helping you cut energy costs.

Crafted from recycled materials, our windows adhere to European environmental standards, ensuring sustainability while preserving the character of your home.
