Almost every water complaint we receive between June and September could have been prevented in the six weeks before it. Water does not find new paths during the monsoon; it uses the ones that were already open. The rain simply supplies enough volume to make them obvious.
So through May we walk every building we manage, top to bottom, with the same list. It takes half a day per tower. It is the single highest-return exercise in our calendar.
The terrace comes first
We start on the roof because the roof decides the rest. Drain outlets get cleared and then flood-tested with a hose — a clear-looking mouth often sits above a choked downtake. We check that the waterproofing coat has not chalked or lifted at the parapet junction, which is where it almost always fails first. Any overhead tank overflow pipe that discharges onto the slab instead of into a drain gets re-routed, because a slow overflow across a terrace for four months does more damage than a storm.
Then the skin
- External cracks wider than a hairline, particularly around window sills and at slab-to-masonry joints.
- Window sealant — the perimeter bead on aluminium frames has roughly a five-year life in our climate and nobody ever budgets for it.
- Sill slope. A sill that has been tiled flat during a flat renovation will push water inward for the life of the building.
- Rainwater downpipes — joints, clamps, and whether anyone has connected a washing machine outlet into one.
Everything electrical that lives outdoors
Facade lighting, podium lighting, pump starters, gate motors, and the DG changeover panel. We test earthing values rather than assume them, and we replace any junction box whose gasket has gone brittle. A monsoon tripping fault at 2am costs a night of everyone’s sleep and usually a burnt contactor.
The basement
Sump pumps get run under load, not just switched on. Float switches get tested by hand. We confirm there is a second pump and that it is on a different circuit, because the failure mode that floods a basement is not a pump dying — it is both pumps sitting on one tripped breaker.
What we tell owners
The pre-monsoon list is not a maintenance wish list. It is triage. If a building can only fund part of it in a given year, the order is drainage, then waterproofing joints, then facade sealant, then cosmetics. Cosmetic work done before drainage work is money spent twice, and we would rather say so in May than explain it in August.
