Different mesh products have different handling and fixing requirements. Share the proposed product and the screen dimensions before ordering. This is ordinary insect-screen work; stronger-sounding product labels do not turn an ordinary frame into a certified security or protective screen.
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.
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. Scope limits: Ordinary insect mesh and compatible screen frames only. No security screens, fall-protection claims, specialist glazing or inaccessible high-level work.
