What Is Sick Building Syndrome and What Causes It?
Last updated October 25, 2026
The short answer
Common Symptoms People Report
People experiencing Sick Building Syndrome often report feeling much better when they leave the building. Symptoms can include headaches, dizziness, fatigue, and irritation of the eyes, nose, or throat. Skin rashes and difficulty concentrating are also common complaints. These symptoms typically lack a single identifiable illness but are clearly linked to time spent in the building.
The pattern of symptoms is key for recognizing the syndrome. They usually appear after entering the building and lessen or disappear after leaving. Multiple occupants in the same building often report similar issues. This distinguishes it from individual allergies or a personal medical condition.
Poor Ventilation and Chemical Contaminants
Inadequate ventilation is a leading cause, as it allows pollutants to build up inside. Modern buildings are often tightly sealed for energy efficiency, which can trap contaminants. Without sufficient fresh air exchange, carbon dioxide and other gases accumulate. This stale air environment directly contributes to occupant discomfort and health symptoms.
Chemical contaminants from indoor sources are another major factor. These can come from adhesives, carpeting, upholstery, cleaning products, or pesticides. Even office equipment like printers and copiers can emit volatile organic compounds. These chemicals can off-gas into the air, creating a mix that irritates the respiratory system over time.
- Adhesives and manufactured wood products
- Paints, varnishes, and solvents
- Cleaning agents and air fresheners
- Pesticides and insect repellents
- Emissions from office machinery
- Combustion byproducts from indoor activities
Biological Contaminants and Water Damage
Biological contaminants are a significant trigger, often stemming from excess moisture. Mold, bacteria, viruses, and pollen can thrive where water has intruded. These microorganisms release spores and metabolic byproducts into the air. Inhaling these particles can cause allergic reactions and respiratory distress, mirroring Sick Building Syndrome symptoms.
Water damage is a primary source for these biological growths. Leaky roofs, plumbing failures, or high humidity can create the damp conditions mold needs. In Melbourne's humid subtropical climate, indoor moisture control is especially important. Unaddressed water damage behind walls or under floors can create an ongoing contamination problem.
How Water Damage Restoration Helps
Addressing hidden water damage is a critical step in resolving Sick Building Syndrome causes. The pros focus on finding and stopping the water source, then thoroughly drying all affected materials. This process removes the moisture that allows biological contaminants to flourish. Proper drying helps prevent the cycle of mold growth and spore release.
The restoration process also involves cleaning and sometimes removing contaminated materials. Porous items like drywall or carpet padding that cannot be fully dried often need removal. This eliminates the reservoir for mold and bacteria. The goal is to return the building to a dry, clean standard so it no longer makes people sick.
Steps to Take If You Suspect It
If you suspect Sick Building Syndrome, start by documenting your symptoms and their timing. Note when they start and stop relative to being in the building. Report your concerns to the building manager or employer. They have a responsibility to provide a safe indoor environment and may initiate an indoor air quality investigation.
A professional inspection is often necessary to identify hidden problems. For issues related to water damage and mold, local water damage pros can perform a detailed inspection. They use moisture meters and thermal imaging to find damp areas you cannot see. Identifying and fixing these underlying moisture issues is essential for long-term relief.

Can Sick Building Syndrome cause long-term health problems?
For most people, symptoms are temporary and resolve after leaving the building. However, prolonged exposure to certain biological contaminants like mold can potentially lead to chronic respiratory conditions or worsen asthma. If you have persistent symptoms, it is important to see a doctor for a proper evaluation.
Who is responsible for fixing a sick building?
Responsibility typically falls on the building owner or employer who controls the property. Tenants should report issues in writing to their landlord. In workplaces, employers have a general duty to provide a safe environment. An investigation by qualified professionals is needed to pinpoint the exact causes.
Does water damage always lead to Sick Building Syndrome?
Not always, but it is a very common contributor. Water damage creates ideal conditions for mold and bacteria, which are frequent biological triggers. If the damage is minor and dried completely within 24 to 48 hours, the risk is lower. Hidden, chronic leaks pose the greatest threat to indoor air quality.
