Small Wall Cracks May Not Be So Small – Insights After the April 2025 Earthquake in Thailand

Earthquakes and Building Structures: What You Should Know
Earthquakes are natural phenomena caused by the movement of the earth’s crust. When seismic waves travel through the ground, buildings are subjected to forces that differ from normal vertical loads. Most buildings in Thailand are primarily designed to bear vertical loads, not the horizontal forces produced by earthquakes. As a result, many structures may be vulnerable during such events.

The April 2025 Earthquake and Its Impact on Buildings in Thailand
The earthquake that occurred in Thailand in April 2025 caused widespread concern about the structural integrity of homes and condominiums. Reports indicated that several properties, particularly condominiums, sustained damage ranging from minor wall cracks to serious structural issues.

While Thailand’s building codes do include some earthquake-resistant standards, many buildings constructed before these codes were implemented—or those lacking proper maintenance—remain at higher risk, even during moderate seismic activity.

What Renters and Condo Owners Must Know After the Earthquake

The recent earthquake has sparked questions and anxieties for both renters seeking condos without earthquake damage and property owners evaluating whether repairs are needed. A key concern is the appearance of “small cracks on the wall,” which may seem minor but could signal deeper structural problems.

Visible Cracks vs. Hidden Structural Issues

Cracks on condo walls after an earthquake can be either cosmetic or signs of more serious damage. Renters looking to rent a condo with no earthquake-related cracks should understand that different types of cracks indicate different levels of concern:

Cracks That May Indicate Structural Problems:

Diagonal cracks: Often indicate foundation settlement
Cracks wider than 3 mm: May signal structural damage
Cracks that continue to grow: Suggest the structure is still unstable
Stair-step cracks: Commonly found in load-bearing walls and indicate serious issues

Cracks That May Be Easily Repaired:

Hairline cracks in paint or plaster
Cracks along material joints
Small, non-expanding horizontal cracks

Tips for Renters Seeking a Safe Condo After the Earthquake

If you’re looking to rent a house or condo with no earthquake damage after the April 2025 quake, here’s what to look for:

Request structural inspection reports: Safe condos should be inspected by a licensed structural engineer.
Examine repaired cracks: Ask about the severity of past damage if you see multiple repair marks.
Check door and window frames: Difficulty in opening/closing may indicate structural shifts.
Inquire about repair policies: Understand how the building’s management plans to handle earthquake-related damage.
Review maintenance history: Well-maintained condos typically fare better during natural disasters.

Advice for Property Owners Considering Repairs

If you’re a condo owner unsure about repairing visible cracks post-earthquake, consider the following:

What You Should Do:

Consult professionals: Hire a structural engineer to assess the damage.
Document cracks: Take photos and measure cracks to monitor changes over time.
Evaluate property value: Unrepaired damage could impact resale or rental income.
Check your insurance policy: Earthquake-related cracks may be covered under your plan.

Repairs You Should Not Delay:

Structural cracks: Must be repaired promptly to ensure safety.
Cracks causing potential leaks: Should be sealed to prevent water intrusion.
Growing cracks: Need immediate attention and a professional evaluation.

Conclusion: Safety Comes First

Whether you’re a renter searching for a safe condo with no earthquake cracks or a property owner looking for a company to manage repairs and maintenance, the key priority is safety. Small cracks may seem insignificant, but if left unchecked, they could develop into major problems. Investing in professional inspections and timely repairs protects both lives and long-term property value.

For property owners who lack the time or expertise to handle these concerns, partnering with a reliable property management company can help ensure that your house or condo remains in top condition, including coordinating with repair technicians and overseeing restoration work.

If you’re currently looking to rent a house or condo in Thailand with no damage from the April 2025 earthquake, thorough inspections and clear communication with landlords or agents will help you make confident, informed decisions. Safety should never be compromised—especially when it comes to your home.
