Bird & Pigeon Problems on Building Facades
The streaking down a building face is not coming from the whole facade. It comes from a handful of horizontal bands — sills, string courses, cornices, sunshades — and the rest of the wall is simply where it lands. Identify the bands and the job gets a great deal smaller.

At a Glance
- Work top down. Birds land on the highest outer line and move inward and downward.
- The streaking you can see usually starts higher than you think — look a floor or two above it.
- Access dominates the cost, so sequencing decides the price more than the product does.
- Do a whole elevation at a time. Treating four floors just concentrates them on the rest.
- The sheltered corners, not the open bands, are where the nesting happens.
A vertical wall is not usable by birds. Everything that projects from it is. On a typical Indian facade that means the window sills, the sunshades above them, the decorative string courses running horizontally between floors, the cornice at the top, and the parapet above that.
Those bands are a small fraction of the facade area and they generate all of the mess. Because they run the full width of the building, though, the running metres add up quickly — and because they are at height, access rather than material usually sets the price.
Do It Top-Down, in One Visit
The sequencing mistake that wastes the whole job
A facade has to be worked from the top down. Protect the second-floor sills first and the birds carry on using the cornice above, which re-fouls everything you just cleaned. Within a season it looks as though the spikes did nothing.
The same applies to phasing by budget. If only part can be afforded, do the top bands — parapet and cornice — not the ones at eye level. Protecting the highest perch pushes the population off the building; protecting the lowest just moves them up.
Access Is the Real Cost
| Access method | Suits | Note |
|---|---|---|
| Ladder | Ground and first floor only | Cheap, and rarely enough |
| Scaffold | Low-rise, or where other work is also happening | Expensive alone; sensible if the building is being painted anyway |
| Suspended cradle | High-rise with existing provision | Uses what the building already has |
| Rope access | High-rise without cradle provision | Usually the practical route on tall buildings |
| From inside each window | Sills and sunshades only | Slow, but needs no external access at all |
Time it with the painting cycle
The single biggest saving available on a facade job is to do it while scaffold or a cradle is already up for painting or repair. The access is the expensive part and it is already paid for. Societies that plan this alongside repainting spend a fraction of what a standalone job costs.
Which Bands Actually Need Protecting
| Band | Priority | Why |
|---|---|---|
| Parapet | Highest | The main roost. Everything below is downstream of it. |
| Cornice | High | Wide, sheltered under the overhang — nesting, not just perching. |
| String courses / horizontal bands | High | Continuous across the whole elevation. Big quantity, big effect. |
| Window sills | Medium | Many small runs. Streaks land on the flat below. |
| Sunshades / chajjas | Medium | Sheltered, so often the nest rather than the perch. |
| Decorative mouldings | Medium | Appearance constraints usually apply here. |
| Column and pilaster tops | Medium | Small flat capital — a favoured single perch. |
| Signage and light housings | Varies | Flat tops right above the entrance. |
| Plain wall | None | Unusable. It only receives. |
Appearance From Street Level
On a commercial or heritage facade this is a real constraint, and it is worth being accurate about it.
- Spikes are seen edge-on from the ground. Fitted on a horizontal band and viewed from below, they read as a thin line rather than as a row of pins.
- The streaking is far more visible than anything fitted to prevent it. Vertical white marks down a painted elevation are what people actually notice.
- Colour matters more than size on a visible facade. Match the base to the band rather than the wall behind it.
- Keep the line continuous. A run that stops and starts looks worse than one that runs the full band, and birds use the gaps anyway.
Working Out the Quantity
A facade is one of the few jobs that can be quantified without going up. Take the elevation drawing, or a straight-on photograph of each face, and measure:
- Building width × the number of horizontal bands = band metres.
- Sill width × the number of windows = sill metres.
- Parapet and cornice perimeter, including returns.
- Band depth for each — anything over roughly 200 mm needs two rows, which doubles those metres.
- Which elevations actually need doing. Faces overlooking open ground or a road are used far more than a face against the neighbouring building.
Send those numbers and the quantity can be worked out before anyone goes up.
Which Product
Bird Spikes
The main product across a facade. Narrow bands, sills, sunshades and mouldings.
Fits: sills, string courses, sunshades, narrow cornices, capitals
Pigeon Spikes
For the wide bands — deep cornices, projecting string courses and broad copings where a narrow row would leave usable footing beside it.
Anti Bird Net
For recesses rather than bands — a deep balcony void, a service shaft opening, a gap behind a facade panel, or a sheltered nesting pocket that cannot be spiked.
Individual Facade Surfaces
- Window sills
- Ledges
- Edges and copings
- Decorative mouldings
- Cornices and beams
- Pelmets
- Pillars and columns
- Parapet at the top
By application: rooftops and windows, which are where most facade work starts and finishes.
Residential, Commercial and Industrial
Residential
Society elevations. Almost always a committee decision, and best planned alongside the repainting cycle when access is already arranged.
Commercial
Offices, hotels and showrooms, where the streaking is a presentation problem and appearance constrains the specification.
Industrial
Admin blocks and office frontages within a plant, usually specified with the sheds behind them.
Why Choose SpikeZone
- Direct manufacturer — on a facade the whole elevation must match, and mixed batches show from the street.
- Multiple coverage widths, because a facade has narrow sills and wide cornices on the same building.
- Quantities from your elevation drawing or straight-on photographs, before anybody arranges access.
- Project and bulk supply, including phased delivery where a society does one elevation at a time.
- Pan-India despatch.

Frequently Asked Questions
Do I have to protect the whole facade?
No. Only the projecting horizontal bands are usable — sills, string courses, sunshades, cornices, parapet. Plain wall cannot be perched on. The area needing protection is a small fraction of the elevation.
Where should I start if I cannot afford all of it?
At the top. Parapet and cornice first. Protecting the lowest bands while the highest are still in use just moves the birds up and re-fouls what you cleaned.
Will spikes spoil the look of the building?
Far less than the streaking does. Fitted on a horizontal band and seen from the ground, they read as a thin line. Matching the base colour to the band matters more than the size.
How is a facade job priced?
Material by running metre, but access usually dominates — scaffold, cradle or rope. Doing it while access is already up for painting is the single biggest saving available.
Can you quote from photographs?
Yes. A straight-on photograph of each elevation, plus the building width and the band depths, is enough to work out the quantity before anyone goes up.
Our building is heritage. Can anything be fitted?
Usually, but the fixing method and appearance both need care, and there may be consents involved. Send photographs of the specific mouldings and we will tell you what suits — see also decorative mouldings.
Do you supply for a whole society elevation?
Yes, including phased supply where the committee is doing one face at a time. Give us the elevation dimensions and band depths.
Streaking Down Your Building?
Send a straight-on photograph of each affected elevation, the building width, and the depth of the main horizontal bands. We will tell you which bands to do, in what order, and the running metres — before you arrange any access.
