Meet the team


Sustainability forms the foundation of Sash Window Preservation, shaping our methodology and practices since our inception in 2010. Our primary mission is to minimize our carbon footprint and move towards carbon-neutrality. We prioritize the reuse of existing sashes and, when necessary, we exclusively utilise FSC®️ and Cradle to Cradle Platinum Gold Certified Accoya treated wood. This material boasts a low carbon footprint, is non-toxic, and eliminates any risk of leaching harmful chemicals or synthetic compounds, ensuring safety for humans, pets, and the environment.


In instances where sashes need replacement, our customers are presented with the option to upcycle or reuse them in household projects, or we can responsibly recycle them ourselves. Currently, we achieve a 93% rate of recycling and reusing existing waste, with plans to further increase this figure towards 100%. Our fleet already includes two fully electric vehicles, and we aim to expand this environmentally friendly approach in the years to come. Clearly, sustainability lies at the core of our business, driving us to continually seek innovative ways to advance this commitment.


Below, you will find a list of policies, practices, and procedures that showcase our commitment to sustainability:

  1.  We currently have 15% of our fleet operating with fully electric vehicles, significantly reducing CO2 emissions. As technology advances, we plan to expand our electric fleet to meet the needs of our operations.

  2. Each quotation provided is completely bespoke, taking a holistic approach to conserving materials. We prioritize reusing materials such as timber, considering factors like timber condition, window depth, and molding type. This approach not only reduces CO2 emissions but also minimizes waste and costs for our clients.

  3. All Our timber is sourced sustainably, with all sashes crafted from Accoya Timber, ensuring environmental responsibility in our manufacturing process.

  4. All of our new joinery is produced in Norwich, UK, minimizing transportation emissions by delivering directly from our workshop to your property.

  5. Similarly, 97.5% of our new glazing units are manufactured in Norwich, UK, reducing transportation emissions and promoting local production.

  6. We recycle old sashes, further contributing to our efforts in waste reduction and sustainability.

  7. Half of our office staff work remotely at least once a week, reducing the carbon footprint of our operations.

  8. We are continuously improving our efficiency in order processing and on-site work, impressing customers with our swift and minimal presence on their property.

  9. Video quotes now account for 20% of our quotations, significantly decreasing our car emissions and embracing innovative technology for a more sustainable approach.
