Professional Interior Wall Crack Repair Services in Singapore

Interior wall cracks can occur due to natural structural settling, thermal expansion and contraction, humidity shifts, or poor plaster application during initial construction. In many properties, concealed water seepage from nearby bathrooms or external walls can also weaken internal plaster and drywall joints, causing hairline or deep visible cracks over time.

Cosmetic cracks are usually thin, hairline fissures (less than 1-2mm wide) on plaster, paint layers, or drywall tape joints. Structural cracks are typically wider than 3mm, run diagonally or in a staircase pattern, and may cause door frames to stick or windows to jam. Our technicians conduct thorough non-invasive inspections to accurately diagnose the severity of your wall cracks.

Simply painting over interior cracks is only a temporary cover-up. Without proper crack preparation, joint taping, and flexible high-performance filler, natural building movements will cause the crack to reappear through the new paint within weeks. Professional crack repair ensures a long-lasting, invisible, and seamless finish.

We use a combination of V-groove crack widening, fiber-mesh tape reinforcement, and premium flexible elastomeric compounds or micro-cement fillers depending on the wall material (plaster, drywall, or brickwork). For deep or water-damaged cracks, we apply specialized moisture-resistant primers and polyurethanes to guarantee long-term stability.
