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 a handle, latch, hinge, track or screen is visibly worn or damaged. Causes: movement, dirt or damage around the relevant hardware or loose compatible fixings or adjustment points.
Mesh needs suitable tension without distorting the frame. Corners and long sides should be checked during fitting, following the material requirements. Over-tightening is not a way to strengthen an old frame, and loose mesh may reflect a retaining-channel problem.
Remeshing relies on a usable frame with sound corners and retaining channels. A bent or cracked frame may need replacement instead. Tight new mesh should not be used to pull a distorted frame into shape or disguise damaged attachments.
Fit suitable mesh and spline to an accepted sound frame, or install a compatible ordinary supplied screen and check its fit. Limits: Ordinary insect mesh and compatible screen frames only. No security screens, fall-protection claims, specialist glazing or inaccessible high-level work.
