Most homeowners step into a freshly collected flat and notice the big things — the light, the layout, the view. The items that quietly drain time and money later are usually far more ordinary: a hairline crack above a door frame, a tile that sounds hollow under a knuckle, a faint stain on a ceiling that reappears after every heavy downpour. A structured residential defect check exists to catch exactly these details before renovation starts, while the Defects Liability Period — typically 12 months from key collection — is still open for you to submit a rectification list. Below is what inspectors most often record across walls, floors and wet areas, and why each finding matters to a Singapore homeowner.
Wall and Ceiling Findings: Cracks, Hollow Tiles and the Seepage Story
Walls and ceilings make up the largest visible surface area in any unit, which is why they also collect the largest number of small findings. On painted walls and ceilings, a defect check typically looks for cracks, unevenness, stains, patchiness and inconsistent paint coverage. Some hairline cracks are cosmetic — normal drying and settlement in a new build — while others follow a pattern that suggests movement around a joint, a beam line or a door opening. Either way, each one should be documented with its location and a clear description, because “crack in master bedroom” is not a useful line item when it reaches the contractor.
Water seepage deserves separate attention. Stains near window frames, discolouration on ceilings beneath a wet area, or damp patches in the living room, bedrooms, kitchen and toilets are all red flags in a new unit. Moisture meters and thermal scanners help an inspector confirm whether a stain is an old splash mark or an active leak travelling from somewhere else. That distinction matters: a paint touch-up hides the symptom, while the actual source may sit above your ceiling or behind a wall.
Hollow tiles, lippage and grout lines
On tiled walls — bathrooms, kitchen backsplashes, feature walls — the most common findings are hollow tiles, lippage, chips and cracks, uneven tone or staining, scratches, and inconsistent grouting. Hollow tiles are detected by tapping with a rod; the dull, empty sound tells you the adhesive did not bond fully behind the tile. A hollow tile may look perfect for years, then debond or crack the moment something knocks it. Lippage is the other quiet culprit: one tile edge sitting slightly proud of its neighbour. It catches light, catches fingers, and often chips along the edge later. Uneven grout lines are not just cosmetic — gaps and inconsistent joints give water a path behind the tiling in wet zones. Inspectors also check overall evenness across the wall plane, since a wavy surface becomes obvious once cabinetry or a mirror is installed against it.
Floor Finishes: Tile Lippage, Hollow Spots and Joints That Give Way
Floor findings tend to be physical rather than visual, which is why a quick emotional walkthrough so often misses them. On tiled floors, a defect check covers the same family of issues as walls — hollow tiles, lippage, chips and cracks, uneven tone or stains, scratches, grouting — plus edge pointing and alignment where the floor meets a wall, threshold or door frame. Misaligned edge cuts and ragged pointing are easy to live with until you notice them every day; hollow floor tiles are worse, because the failure usually happens under a heavy item or in a corner nobody inspects until something cracks.
Testing is deliberately low-tech and repeatable. An inspector walks the floor, taps across a grid of tiles, runs a spirit level or straightedge across the surface, and checks the fall at thresholds. Where a laser level is used, it confirms whether a dip is localised or part of a broader slope issue — useful evidence when the contractor disputes that anything is wrong.
Vinyl and engineered-wood flooring
If your unit came with vinyl or engineered-wood flooring, the checklist shifts. Typical findings include cracks, scratches, uneven joints and gaps, and loose pieces that are not sitting flush — often a sign that the substrate was not self-levelled before the boards went down. A loose plank announces itself as a soft spot, a faint click underfoot, or a visible ridge along a joint. These defects are especially easy to overlook in resale units and post-renovation homes where furniture already hides the worst patches, and they are awkward to fix once skirting and built-ins are in.
Because flooring defects are so often buried under the next stage of work, they are worth flagging early. Renovation timelines rarely allow for a floor to be lifted twice, and a documented finding before carpentry begins keeps the conversation simple.
Wet Areas and the Service Yard: Where Small Gaps Turn Into Big Bills
Bathrooms, kitchens, yards and the boundaries around windows are where the consequences of small defects are largest. In toilets, inspectors look at sanitary ware for chips and cracks, check for leaks around joints, test for consistent water flow, listen for odours or gurgling sounds from drains, and confirm that fixtures are securely fastened rather than rocking on their seals. Gaps in silicone and sealant around basins, shower screens and floor-to-wall junctions are recorded individually, since these are the entry points for slow, invisible water damage.
The water ponding test is the simplest and most revealing check in any wet area. Water is poured from the furthest end of the floor so it should flow uninterrupted towards the floor trap; any puddling that remains indicates the floor fall is wrong. Standing water near a threshold, under a vanity or at the shower edge will eventually find its way into the adjacent room or the unit below. This is the kind of detail an independent inspection is built around — a systematic, room-by-room record rather than a walkthrough — and providers such as Defect Check document each item with a description and location so the rectification list is unambiguous when it reaches the developer, main contractor or HDB.
Kitchen, yard plumbing and the service yard
Kitchen and yard plumbing findings tend to be practical: floor-trap and washing-machine outlet chokage, weak tap pressure, and a loose cap on the yard tap. In the service yard, inspectors check the overhead hanger lowering mechanism, rust on the external clothes hanger metal, pipe paint and leaks, ceiling and edge stains, and the bifold door — its lock, smoothness, rubber gasket and any scratches, chips, cracks or rust. Around windows, gasket and seal gaps, stiff or rusty hinges, loose handles and casement stays all feed into the same water-ingress story, because a failed seal lets rain track in behind the frame. Individually these are minor items. Collected together and documented in a report, they give you a clear, defensible list to submit while the defect liability period is still running and before renovation work seals the evidence away.
