What sets us apart from other’s
Our expertise lies in the careful restoration of period timber windows, ensuring they retain their original charm while improving functionality and energy efficiency. Unlike many other providers, we handle every aspect of the restoration process in-house, from initial assessment to full repair, reglazing, and a professionally painted finish. This allows us to maintain the highest standards at every stage of the project while ensuring seamless project management and timely completion.
Our meticulous attention to detail, superior quality of work, and dedication to customer satisfaction. We collaborate closely with our clients to understand their specific individual requirements, providing a tailored restoration solution that respects the historical integrity of each project. Whether working on listed buildings, heritage sites, period homes large or small, we pride ourselves on delivering exceptional results that stand the test of time.

Consider this! Whilst we’re working in your home
Most contractors work in homes without any dust extraction systems, air purification, or dust barriers, allowing fine dust to spread freely throughout the space. This dust settles on furniture, floors, and even in ventilation systems, making cleanup a hassle and potentially causing long-term air quality issues. In contrast, we offer a more advanced and considerate approach.
Our use of dust extraction tools helps capture debris at the source, while an optional temporary dust wall barrier prevents it from traveling to other areas of your home.
Additionally, our air purification system actively removes airborne particles, improving indoor air quality and creating a healthier environment—especially beneficial for those with allergies, asthma, or respiratory conditions. These measures not only keep your home cleaner but also ensure a more comfortable and professional restoration experience compared to traditional methods.
Your windows are the eye’s to the world, & we can make them shine again.
