Homebuyer Resources

The monsoon season in Pune typically arrives in June and extends through September. For residents who have recently moved into a new flat, whether as first-time owners or those shifting from older housing, the first monsoon is often the most instructive. Flats that are well-maintained heading into the season experience significantly fewer issues. Flats that are not often surface problems that could have been avoided: water seepage through poorly sealed windows, bathroom leaks traced to worn-out grouting, or mildew in areas that were never properly ventilated. This checklist is organised by area of the home. Work through it section by section in May or early June, before the rains arrive, and use it again mid-season if you notice anything developing. 1. Windows and Balcony Doors Windows and balcony-facing doors are the most common entry points for water during heavy rain. Even minor gaps in weatherstripping or old sealant can allow water ingress over sustained rainfall. Check before the season: Inspect all window frames for cracks or gaps in the sealant along the outer edge. Test the rubber gasket or weatherstrip on sliding windows. It should compress evenly when the window is closed. If it feels stiff, cracked, or uneven, replace it. Check that all window latches and locks close completely with no visible gap at the top or sides. For balcony sliding doors, inspect the drainage channels at the base of the track. Clear any debris that might block water from draining away from the door frame. If you have louvred or casement windows, check the pivot joints and hinges for corrosion. Hinges that do not close fully will leave a gap. Tip: If you see white mineral deposits (efflorescence) along window edges or on the wall below a window, it is a sign that water has been seeping through. Address the sealant before the monsoon begins. 2. Bathroom and Kitchen: Grouting, Drains, and Sealant Bathrooms are one of the most maintenance-intensive areas during the monsoon, not because of rain directly, but because humidity accelerates the deterioration of surfaces that are already under stress from daily water use. Tile grouting: Run a finger along all tile joints in the bathroom. If the grout feels soft, powdery, or shows cracks, it needs to be re-grouted before the season. Pay particular attention to the area where the wall meets the floor (the cove joint). This is where most bathroom leaks originate. In the kitchen, check grouting behind the sink and along the backsplash, particularly around pipe entry points. Drains: Clear all floor drains in bathrooms, the kitchen, and the balcony. Remove any accumulated soap residue, hair, or debris. Pour water down each drain to confirm it drains freely. A slow drain signals a partial blockage. Address it before the season when drain load increases. Check that the drain cover is properly seated and has no cracks. A missing or broken drain cover allows debris to enter the pipe. Silicone sealant: Inspect the sealant bead around the base of the toilet, around the wash basin pedestal, and along the edges of the shower area. If the sealant is discoloured (yellowing or blackening) or has visible gaps, re-seal using a sanitary-grade silicone sealant before the monsoon. Note: Black mould on sealant is not only cosmetic. It indicates the sealant has been breached and moisture is getting behind the surface. This is worth addressing promptly. 3. Walls and Ceiling: Seepage and Paint In newer flats, internal wall seepage is less common than in older buildings. But it is still worth checking, particularly in flats on upper floors and those with external walls facing the prevailing rain direction (typically west-southwest during Pune’s monsoon). Look carefully at all external-facing walls. Run your palm across the surface. Damp patches or soft spots in the plaster indicate that water is getting through the exterior. Check ceilings in the bathrooms and in rooms below the terrace or roof. Staining, bubbling paint, or soft spots are signs of water accumulation above. Inspect the wall area around AC sleeves and exhaust fan openings, as these are common entry points where sealant may have deteriorated. If any wall shows flaking or bubbling paint on the interior side, this is a sign of moisture migration, not a surface issue. Re-painting over it without fixing the source will not hold. For new flat owners: If your flat is newly handed over and you notice seepage in the first monsoon, this typically falls under the builder’s defect liability period (usually one to two years under MahaRERA guidelines). Document the issue with photos and dates and report it to your building management. 4. Electrical Points and Appliances Water and electricity are the most dangerous combination in any home. A few targeted checks before the monsoon significantly reduce risk. Look at electrical sockets and switches in the kitchen, bathroom, and balcony. These are areas with higher moisture exposure. Check for any yellowing, scorch marks, or looseness in the face plate. Check that all outdoor or semi-outdoor electrical points (balcony light switches, external AC units) have functioning weatherproof covers. If you have a geyser in the bathroom, confirm the power switch is located outside the bathroom. This is standard in modern construction but worth verifying. Test all MCBs (Miniature Circuit Breakers) in your distribution board. Each should trip and reset cleanly. If any feel stiff or do not reset properly, have an electrician inspect them. Check the earthing connection. If your flat is in a new building, this is typically in order, but it is worth confirming with building management that the earthing system is inspected before the season. Important: Never attempt to inspect or repair electrical fittings yourself if you are uncertain. For any switch, socket, or board that shows signs of moisture damage, call a licensed electrician. 5. Waterproofing: Terrace, Balcony, and Utility Area If your flat includes a private terrace or large balcony, waterproofing is the single most important pre-monsoon task. An inadequately waterproofed surface will allow water to pool and eventually seep into the
