7 signs your façade needs maintenance

1. Visible stains or streaks: algae, mildew or pollution that won't wash off with rain.
2. Cracked or missing sealant: leads to water ingress and structural damage.
3. Loose panels or tiles: a falling hazard for pedestrians.
4. Rust staining: indicates embedded steel corrosion.
5. Efflorescence: white salt deposits on concrete or stone.
6. Window seal failure: condensation between glass panes.
7. Tenant complaints: the most reliable early-warning system.

If you spot two or more of these, schedule a professional inspection within 30 days.
