Termite damage develops silently, often inside wall cavities, under flooring, or within timber door and window frames, and is frequently only discovered once the damage is extensive enough to be structurally or financially significant.
Pre-construction soil treatment, applied to the foundation trench and beneath the slab before concrete is poured, is by far the most cost-effective point in a project to prevent termite infestation — a few thousand rupees spent at this stage can prevent lakhs of rupees in repair costs a decade later.
For existing, occupied buildings, post-construction treatment uses targeted injection around the foundation perimeter, timber fittings and any known entry points, since the soil beneath an existing slab cannot be treated the same way as an open foundation trench.
Termite control should be treated as a maintenance item, not a one-time fix. Chemical treatments have an effective protection period, typically five to eight years, after which reapplication is recommended, particularly in ground-floor properties surrounded by garden beds or timber landscaping features.
If you notice discarded termite wings near windows, hollow-sounding timber, or thin mud tubes along a foundation wall, these are early warning signs worth acting on immediately rather than waiting for visible structural damage.
