Opening windows and doors is one of the simplest ways to bring fresh air into a home—but flies, mosquitoes and other insects often arrive with it. A custom fly screen creates a practical barrier while preserving ventilation and much of the view.

The key word is custom. A screen that is accurately made for the opening will look neater, seal more effectively and be easier to use than a one-size-fits-all product.

Begin with the opening type

The way a window or door opens determines which screen system will work best. A fixed screen may suit a window that does not need frequent access, while a removable screen makes seasonal cleaning easier. Hinged, sliding or other purpose-designed systems may be more suitable for doors and frequently used openings.

Consider handles, locks, security fixtures, curtains, blinds and the direction in which each panel moves. The screen must provide clearance for normal operation rather than obstructing the existing system.

Select mesh for your priorities

Mesh is available in different materials, colours and densities. A standard insect mesh may be ideal for general household use, while finer mesh can help with smaller insects but may reduce airflow and visibility slightly.

Homes with energetic pets or children may benefit from a more robust mesh in selected openings. No mesh is indestructible, so the expected use should be discussed honestly when choosing the product.

Dark mesh often appears less noticeable when viewed from inside because the eye looks through it, while lighter mesh may suit certain frame colours or interiors. It is worth comparing samples in the actual light before deciding.

Match the frame to your home

An aluminium frame is durable, slim and easy to maintain. Matching or coordinating the finish with existing windows and doors gives the installation an intentional appearance.

The frame must also be sufficiently rigid for the opening size. Large panels may need different profiles or intermediate support to remain stable and keep the mesh properly tensioned.

Balance airflow, visibility and insect protection

A denser mesh can block smaller insects, but every increase in density affects airflow and light to some degree. Think about which rooms need the most ventilation and which openings face gardens, outdoor lighting, refuse areas or other insect activity.

Bedrooms and kitchens may have different priorities. A good custom solution does not need to use exactly the same configuration at every opening.

Make cleaning and access easy

Dust and pollen collect on mesh over time. Choose a system that allows practical cleaning without damaging the screen. Many screens can be maintained with a soft brush, gentle vacuuming or mild soapy water, depending on the mesh and frame.

Avoid scrubbing, high-pressure water and harsh chemicals. Removable components should be handled by their frames, not pulled by the mesh.

Accurate measurement makes the difference

Even a small gap can allow insects through, while an oversized screen may bow, rattle or interfere with the window. Openings that appear square are not always perfectly square, particularly in older homes.

A professional measure considers the smallest dimensions, frame condition, mounting position, operating clearance and suitable fixing method. This is what turns a simple mesh panel into a neat, effective part of the home.

A practical checklist

Before ordering, decide:

  • Which insects you most want to exclude
  • How often the opening is used
  • Whether the screen should be fixed or removable
  • How much airflow and visibility you want to preserve
  • Whether pets or children may push against the mesh
  • Which frame colour best suits your windows and doors
  • How the screen will be accessed for cleaning
