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.
Measure the existing screen and show how it sits in the opening. Overall dimensions alone may omit clips, recesses or clearance. A customer-supplied replacement should be checked against the fixing arrangement before purchase, especially where the old screen is missing.
A sound ordinary frame may be worth remeshing; extensive frame damage can make a compatible replacement more practical. Send photographs before purchasing. The service does not promise custom fabrication of any screen system or alteration of the surrounding window assembly.
Fit suitable mesh and spline to an accepted sound frame, or install a compatible ordinary supplied screen and check its fit. Scope limits: Ordinary insect mesh and compatible screen frames only. No security screens, fall-protection claims, specialist glazing or inaccessible high-level work.
