Accoya Wood

Why Woodcock Sash Windows?

From your initial consultation to the final installation, we work closely with you to ensure your satisfaction at every stage. Our passion for quality and attention to detail means you can trust us to deliver windows that stand the test of time.

Flawless Finish

Our paint finish is as crucial as the craftsmanship of the window itself, providing both a protective seal and a beautiful, refined look. Using a specialised, factory-applied spray finish designed specifically for windows, the paint allows the timber to breathe naturally throughout the seasons while safeguarding it from the elements. The result is a clean, smooth finish that enhances the elegance and longevity of your windows.

Enhanced Draught Proofing

By carefully sealing key areas, we drastically improve the performance and insulation of your windows, eliminating cold spots and ensuring smooth, effortless operation. Upgrading your windows with this modern draught-proofing not only boosts comfort but also preserves the traditional charm of your home.

Premium Ironmongery

Ironmongery is the finishing touch that completes the look of your windows, often referred to as the “jewellery” of the window. Available in a variety of elegant finishes, our high-quality hardware enhances the overall aesthetic and provides lasting functionality. These small yet essential details elevate the style of your windows and complement the character of your room.

Ben helped us with every step of the design and created a bespoke door and fanlight window that looks absolutely beautiful and does justice to the glass. Would definitely recommend."

"I highly recommend Woodcock Sash Windows. Ben explained what was needed to get our 4M high sash windows opening properly and came up with a plan to get them sorted. The installation by Ben and Matt went smoothly and they went above and beyond by replacing the existing cordage of the windows and even helped fix one of the curtain rails. Our windows now glide open smoothly and we are very happy with the service."
