Why Wall Cracks Shouldn’t Be Ignored
Cracks on your walls may seem like just a cosmetic issue, but in reality, they could be an early warning sign of deeper structural or moisture-related problems. Whether you’re a homeowner dealing with unsightly hairline cracks in your living room, or a business owner noticing structural cracks in your office walls, timely repair is critical to prevent long-term damage.
In Singapore’s humid climate, factors like building settlement, thermal expansion, and water seepage often worsen cracks if left unattended. That’s why 9Reno Pte Ltd specializes in wall crack line repair services, offering solutions tailored to different wall types – from drywall to brick walls, plaster walls, structural columns, door frames, and even window edges.
Common Types of Wall Cracks and What They Mean
Not all cracks are created equal. Here are the most common wall cracks you might encounter:
- Hairline Cracks – Superficial cracks often caused by drying plaster or minor settlement.
- Vertical Cracks – Can indicate structural movement or foundation settlement.
- Horizontal Cracks – Often a sign of serious stress or water pressure.
- Diagonal Cracks – Usually appear around windows and doors, caused by uneven settlement.
- Spiderweb/Map Cracks – Typically surface-level, common in plaster walls.
