Measure the Opening: Measure the width and height of the window opening. Subtract 10-15mm from both dimensions for a proper fit. Check for Level: Ensure the window opening is square and level. Use a level and adjust as necessary with shims.

If Removing an Old Window

Carefully Remove the Old Window: Take out the old window, removing any trim or interior stops. Be cautious of any remaining nails or screws.

Preparing the Window Opening

Clean the Opening: Clear any debris, dust, or old sealant from the window opening to ensure a clean surface for installation.

Dry Fit the Window: Position the uPVC window in the opening to check the fit. Ensure it sits properly and aligns with the opening. Insert Shims: Place shims underneath the window frame to keep it level and plumb. Screw the Window: Using screws, secure the window to the frame. Drill pilot holes if necessary to prevent splitting the frame. Check for Level and Plumb: Use a level to confirm that the window is straight. Adjust with shims as needed. Insulate and Seal: Fill any gaps around the window with foam insulation or sealant. This helps prevent drafts and improves energy efficiency. Install Trim: Reinstall or add new interior and exterior trim around the window to cover gaps and enhance appearance.
