Frequently Asked Questions
Ceiling cracks are commonly caused by natural building settlement, thermal expansion and contraction, drying plaster, or aged drywall joint tape. More critically, ceiling cracks can result from hidden water leaks originating from upper-floor bathrooms, leaking roofs, or corroded structural concrete reinforcement (spalling concrete).
Hairline surface cracks along plaster or drywall tape seams are generally cosmetic. However, wide cracks (over 3mm), deep cracks accompanied by a sagging ceiling slab, rust spots, or active water drippage are signs of structural concern or concrete spalling. Immediate inspection is recommended for sagging or wide ceiling cracks.
Yes, ceiling cracks in multi-story residential units or HDB flats frequently stem from waterproofing membrane failure in the upper-unit bathroom or kitchen slab. As water seeps through the concrete slab, it expands the ceiling concrete, causing plaster cracks, brownish water spots, and paint peeling.
For moisture-induced ceiling cracks, we utilize high-pressure Polyurethane (PU) grouting injection directly into the ceiling slab to stop water leaks at the source. For cosmetic plaster or drywall cracks, we open the crack, apply fiberglass joint mesh, and seal it with lightweight, high-flexibility ceiling compounds.
If water accumulates above a gypsum board false ceiling due to an unaddressed leak, the material weakens rapidly and can pose a fall hazard. Cracks accompanied by visible bowing or soft spots require immediate professional assessment and repair to ensure household safety.
For concrete spalling (where rebar rust causes concrete chunking and cracks), we remove loose concrete, apply anti-rust primer to the exposed steel reinforcement bar, treat the concrete surface with bonding slurry, and patch it with high-strength structural polymer mortar.
Yes. After structural patching or filling, we smooth-sand the surface to match surrounding ceiling contours. We then apply anti-mould sealer and color-matched topcoat paint to ensure a clean, uniform finish across the entire ceiling.
Standard cosmetic plaster crack repairs usually take 2 to 4 hours. Structural PU grouting or concrete spalling repairs can take around 1 to 2 days, depending on drying intervals for structural mortars and specialized sealing coats.
Repair costs depend on the underlying cause (cosmetic vs. water seepage/spalling), ceiling height, and area size. We provide free initial diagnostic assessments and transparent, itemized quotes before any work begins.
Yes, all our ceiling crack and waterproofing repair solutions include a written warranty covering materials and workmanship. Should any cracking or seepage reoccur within the warranty period, our team will re-inspect and rectify it promptly.
