a handle, latch, hinge, track or screen is visibly worn or damaged. Fit suitable mesh and spline to an accepted sound frame, or install a compatible ordinary supplied screen and check its fit.
Signs: the window is stiff, loose or no longer moves through its normal range or the window does not close, catch or sit evenly as it did before. Causes: loose compatible fixings or adjustment points or movement, dirt or damage around the relevant hardware.
Explain how the screen is accessed and whether removal is possible from a safe position. Upper-level or inaccessible screens may fall outside ordinary access. The quote should identify accepted screens rather than assume every window at the property can be reached.
The retaining spline must suit the frame groove and mesh. Reusing a brittle or incorrectly sized spline can leave an uneven result. Keep any accessible product information and show the groove where visible, without damaging the frame to obtain a sample.
Handle the screen by its frame and follow mesh care instructions. An insect screen is not a security barrier or fall-prevention device. Limits: Ordinary insect mesh and compatible screen frames only. No security screens, fall-protection claims, specialist glazing or inaccessible high-level work.
