Our mesh window guards are manufactured to order, with a typical lead time of 4–5 weeks from order confirmation and final specification. This allows each system to be produced to the required size, mesh type, frame design, and finish.

Lead times can vary depending on mesh specification, frame type, and project complexity, particularly for bespoke designs, large quantities, or security-rated systems such as LPS1175 Level 4 mesh window guards.

Where hot-dip galvanising is specified for external installations, additional time should be allowed, which may extend the lead time beyond the standard 4–5 weeks. We will always confirm accurate timescales at quotation stage to ensure alignment with your project programme.

The cost of mesh window guards is generally competitive, offering a strong balance between security, durability, and cost-effectiveness. Pricing will vary depending on mesh type, frame specification, and installation requirements.

Installation Considerations

Mesh window guards often require:

• Installation into masonry or structural openings
• Use of stand-off brackets where windows need to open behind the mesh
• Working at height for upper-level installations
• Coordination with other building elements such as vents or services

Additional Costs to Consider

• Hot-dip galvanising for external installations

• Access equipment (scaffolding, lifts)
• Removal of existing guards or obstructions

Budget Guidance

Typical budgets are:

• Domestic / light commercial: £300 – £700 per window installed
• Commercial / higher risk environments: £600 – £1,500+ per window installed
• High-security applications: £1,000 – £2,500+ per window installed
