A commercial building may appear to be in good condition while developing problems that aren't immediately obvious. Regular maintenance is important, but certain warning signs may indicate that a professional structural evaluation is needed.


Recognizing these signs early can help property owners and managers better understand the condition of their building and determine whether additional inspection or engineering services are appropriate.

Here are five warning signs that shouldn't be ignored.


1. New or Worsening Cracks


Cracks can occur in many types of building materials, and not every crack indicates a structural problem. However, new cracks or cracks that appear to be increasing in size or number deserve attention.


Cracking in areas such as concrete slabs, beams, columns, walls, or balconies may warrant professional evaluation, particularly when accompanied by other signs of deterioration.


A qualified professional can evaluate the location, size, pattern, and characteristics of the cracks and determine whether further investigation is recommended.


2. Concrete Deterioration or Spalling


Concrete can deteriorate over time due to moisture exposure, corrosion, environmental conditions, and other factors.


Signs of deterioration may include:


  • Pieces of concrete breaking away
  • Exposed reinforcing steel
  • Rust staining
  • Surface deterioration
  • Cracking around reinforced concrete components


Concrete deterioration should not simply be covered up without understanding what caused it. A professional evaluation can help determine the extent of the affected area and whether repairs or additional investigation may be necessary.


3. Water Intrusion or Persistent Moisture


Water can be particularly damaging when it repeatedly enters areas of a building where it shouldn't.

Leaks, persistent moisture, damaged waterproofing, or drainage problems can contribute to deterioration of building materials over time.


Property managers should pay attention to recurring water stains, damaged surfaces, moisture around balconies, or areas where water continues to enter despite previous repairs.


Finding and addressing the source of moisture early can help reduce the potential for additional deterioration.


4. Damaged or Deteriorating Balconies


Balconies are exposed to weather and moisture and require appropriate maintenance and attention.

Property owners and managers should look for visible cracking, concrete deterioration, rust staining, exposed reinforcing steel, or other changes to balcony components.


Because balconies can include structural components, visible deterioration should be evaluated by a qualified professional rather than assumed to be purely cosmetic.


5. Unusual Movement or Changes in the Building


Changes in a building's condition can sometimes be difficult to notice until they become more pronounced.

Examples may include doors or windows that suddenly become difficult to operate, noticeable changes in floors or surfaces, or other unusual conditions that were not present previously.


These signs do not automatically indicate a structural problem, but they can be reasons to have the condition professionally evaluated.


Why Early Evaluation Matters


Discovering a potential structural concern doesn't necessarily mean that a building has a serious structural problem.


The important step is determining what is actually happening.


A professional inspection or engineering evaluation can help property owners understand the condition, identify potential contributing factors, and determine whether repairs, monitoring, or additional investigation may be appropriate.


Addressing concerns early can also give property owners more time to plan maintenance and repairs rather than reacting after a problem becomes more extensive.


What Should Property Owners Do If They Notice These Signs?


If you notice one or more of these conditions, document what you see and consider having the area evaluated by a qualified professional.


Photographs, previous inspection reports, maintenance records, and information about previous repairs can also be useful when evaluating the property's history.


Most importantly, don't assume that a visible problem is either harmless or severe without having it properly evaluated.
