Install insect screens.

Whether you have traditional sash windows, modern uPVC casements, or large bi-fold doors, there is a bespoke screening solution available. High-quality mesh can also offer secondary benefits, such as reducing pollen ingress and providing a slight shade effect during peak sun hours.

What Does the Work Involve?

• Site Survey: Precise measurement of window or door apertures, accounting for handles, stays, and opening clearances.
• Surface Preparation: Cleaning the existing frames to ensure adhesive strips or mechanical fixings bond correctly.
• Frame Assembly: Cutting and joining aluminium or PVC tracks and frames to the exact dimensions of your openings.
• Mesh Tensioning: Fitting the selected mesh (standard, pet-resistant, or pollen-filter) into the frame with a spline tool to ensure it remains taut.
• Installation: Securing the screen using magnetic strips, hinges, or retractable cassettes depending on the chosen model.
• Testing: Ensuring smooth operation of rollers or hinges and verifying that the screen does not interfere with the window's locking mechanism.

Typical Costs

Prices for insect screens vary significantly based on the size of the opening and the complexity of the mechanism. Custom-made retractable or pleated screens are more expensive than fixed frames but offer a much cleaner finish when not in use.

Materials usually include VAT in retail quotes, but always confirm if the labour element includes the 20% tax. Bespoke mesh types, such as "TuffMesh" for households with cats or dogs, typically add 15-20% to the material cost.

How Long Does It Take?

• Survey and Measuring: 30–60 minutes for a standard three-bedroom house.
• Single Window Installation: 45–90 minutes depending on the fixing method.
• Retractable Door Screen: 2–3 hours to ensure the tracks are perfectly level and the tension is set.
• Whole House Install: 1 full day for a professional team to fit 6–10 screens.

DIY or Professional?

Basic "cut-to-size" mesh kits with velcro tape are a viable DIY task for temporary summer use. However, these often peel away in the heat and can look unsightly on premium uPVC or timber frames.

Professional installation is recommended for retractable or pleated systems, as these require perfect levelling to prevent the mesh from jamming. A professional will also ensure that the installation complies with Building Regulations Part B, ensuring the screen can be easily removed or opened in the event of a fire.

Choosing the Right Tradesperson

• Look for installers who specialise in "Blinds and Shutters" or dedicated "Insect Screen" specialists.
• Check if they offer a warranty on both the mesh (against UV degradation) and the mechanical components.
• Questions to ask:
  • Does this screen allow the window to be fully closed and locked without removal?
  • Is the mesh "midge-proof" (essential for Scottish or damp areas)?
  • Can the mesh be easily replaced if it gets damaged in the future?
• Red flags include installers who don't ask about handle protrusions or those who suggest "gluing" frames permanently to your windows.

UK Regulations

• Part B (Fire Safety): Screens must not obstruct designated fire escape windows. They should be easily removable or openable from the inside without a key.
• Listed Buildings: If your home is Grade I or II listed, you may need consent to fix screens to the exterior. Interior-mounted, removable screens are usually preferred by conservation officers.
• Landlord Consent: If renting, you generally need permission to drill into window frames, though magnetic "no-drill" options are available.

Common Problems

• Mesh Sagging: Occurs when DIY kits aren't tensioned correctly or when cheap mesh expands in direct sunlight.
• Handle Interference: If the screen frame depth isn't calculated correctly, you may find you cannot shut your window handle.
• Debris in Tracks: Retractable screens can jam if dust and dead insects accumulate in the bottom channel; regular vacuuming is required.
• Light Reduction: While modern "invisible" mesh is excellent, very fine midge-mesh can reduce light levels by up to 30%.
