New construction: prevention built in
During construction, treatment happens at the foundation and soil stage, before flooring and walls close off access. This is largely preventive — the goal is to create a chemical barrier between the soil and the structure before termites can establish a colony inside.
Existing buildings: treating an already-closed structure
Once a building is finished and occupied, treatment has to work around finished floors, furniture, and walls. This is why existing buildings rely on drilling (drill-fill-seal) or piping systems — methods designed to reach the soil beneath without demolishing anything.
Cost and disruption differences
Pre-construction treatment is generally cheaper per square foot and causes zero disruption since it happens before anyone moves in. Existing-building treatment costs more due to drilling labour and requires the household to accommodate a work crew for a day or more, though normal activities can usually continue in untreated areas.
Either way, get it inspected properly
Whether you are building new or already living in the property, the starting point is the same: a proper inspection to understand what stage you are at and what treatment actually applies. Doon Earth Solution handles both new construction and existing-building treatment across Dehradun, with a free inspection either way.
