Why Balconies Are a Common Bird Problem

Balconies offer birds exactly what they're looking for: shelter, elevation, and a safe ledge. Pigeons in particular are notorious for nesting and roosting on balconies, leaving behind mess, noise, and health hazards. Bird netting is the most reliable long-term solution — and with the right approach, it can be installed neatly without ruining your view.

What You'll Need

  • Bird netting (19mm–50mm mesh, depending on bird species)
  • Stainless steel wire rope or tensioned cable (for the top fixing line)
  • Eye bolts or fixing anchors
  • Zip ties or netting clips
  • Drill and appropriate drill bits
  • Tape measure and marker
  • Wire tensioner / turnbuckles
  • Gloves and safety glasses

Step 1: Measure the Area

Measure the full width and height of the balcony opening, including any gaps at the sides. Add at least 20cm of extra netting on each edge to allow for secure fastening. Write down your measurements and purchase netting that comfortably covers the full perimeter without seams in awkward places.

Step 2: Install the Top Anchor Line

The most common method is to run a tensioned stainless steel wire or cable along the top of the balcony opening:

  1. Drill pilot holes and insert eye bolts at each end of the top edge (into concrete, masonry, or a structural beam)
  2. Thread the stainless steel wire through and pull it taut using turnbuckles
  3. Check that the wire doesn't sag — it should be firm and level

Tip: If drilling into the building is not permitted (e.g., rented property), adhesive anchor pads designed for bird netting are available as an alternative — though they're less robust.

Step 3: Attach the Netting to the Top Wire

Unroll your netting and attach it to the top wire using netting clips or zip ties at regular intervals (every 30–40cm). Make sure the netting hangs straight without bunching.

Step 4: Secure the Sides and Bottom

Work your way down each side, fastening the netting to the balcony railing, wall, or a secondary vertical wire. At the bottom, secure the netting along the base of the railing or floor edge to eliminate any gaps:

  • Use stainless steel staples for wooden surfaces
  • Use clip rings or cable ties for railings
  • Use adhesive fixing strips for tiled or smooth surfaces

Step 5: Check for Gaps

Walk around the perimeter and look for any openings larger than your target mesh size. Birds — especially sparrows — are remarkably good at finding and exploiting small gaps. Pull the netting tight and re-clip anywhere it feels loose.

Step 6: Trim Excess Netting

Use scissors or a Stanley knife to trim any excess netting neatly. Tuck the cut edges behind fixings where possible to prevent fraying and maintain a tidy appearance.

Maintenance Tips

  • Inspect the netting every 3–6 months for wear, especially at fixing points
  • Clear any debris (leaves, twigs) that accumulates in the net to reduce strain
  • Replace corroded fixings promptly to prevent net failure

A well-installed balcony bird net should last several years and require minimal upkeep — giving you a bird-free outdoor space year-round.
