Replacing a window yourself in a garden shed

Ready to replace a window in your garden shed? With our handy guide, you'll tackle the job with ease. We’ll guide you through removing the old window and putting in a new one.

First, check what type of window you have. This guide applies to windows with glazing beads, without sealant. Is your window secured with glazing beads? Then you’re all set to get started!

Use a hammer and chisel to gently loosen the glazing beads. Protect them, as they can be reused. For larger windows, suction cup handles are ideal for safe work. Don’t forget to remove any old sealant residue from the frame.

Accurately measure the old window. Allow 3 mm of clearance for material expansion. Order your custom-sized acrylic or polycarbonate from us using our sheet calculator, for example, 1000 mm x 500 mm. Opt for polycarbonate for extra strength – perfect for a garden shed that has to withstand some heavy weather.

Ensure the frame is clean and free from grease. Place the glazing tape around the frame. This provides a soft foundation and cushioning for the new window. Make sure the glazing tape is 10 mm wide for optimal grip.

Remove the protective film from the new window. Use glazing spacers in the corners to maintain the 3 mm clearance. This ensures the window is securely and precisely positioned.

Apply new glazing tape to the glazing beads and firmly refit them. Stapling or gluing – whichever you find most convenient.

Finally, apply a paintable sealant along the edges for a neat finish and protection against the elements. Don’t forget to clean the window with an anti-static cleaner after sealing. This keeps your new window looking pristine for years.
