Why Campello needs this specifically
Campello’s dense triple-decker lots mean a soil barrier often has to be coordinated around shared foundations and tight side-yard access between buildings.
Older triple-decker foundations bring wood-to-soil contact and shared-wall construction, so subterranean termite activity can spread between adjacent units before anyone notices.
What to know before you call
Professionally applied soil barriers typically protect 5–10+ years — see the soil treatment hub for the full method explainer. See the full termite soil treatment breakdown →
