Mold in Commercial Buildings: Health and Legal Risks

Last updated October 25, 2026

The short answer

Health Risks of Mold Exposure

Mold in commercial buildings can trigger a range of health problems, especially for people with asthma, allergies, or weakened immune systems. Common symptoms include sneezing, coughing, eye irritation, and skin rashes. Prolonged exposure may lead to more serious respiratory conditions, so it is important to take any signs of mold seriously.

If you or your employees feel unwell and suspect mold is the cause, see a doctor for proper evaluation. Mold spores can spread through air ducts and affect large areas, so early detection and removal are critical. Keep the building well-ventilated and address any water leaks promptly to reduce the chance of mold growth.

  • Respiratory irritation like coughing and wheezing
  • Allergic reactions such as sneezing and watery eyes
  • Skin irritation from direct contact with mold
  • Aggravation of asthma or other lung conditions
  • Headaches and fatigue in some individuals
  • Long-term risk of chronic respiratory problems

Steps to Protect Your Business

The right way to reduce health and legal risks is to prevent mold from growing in the first place. Fix any roof leaks, pipe leaks, or flooding issues as soon as they occur. Keep indoor humidity levels low, ideally between 30 and 50 percent, and ensure adequate ventilation in areas prone to moisture, like restrooms and kitchens.

Regularly inspect your building for signs of water damage, such as stains, peeling paint, or musty odors. If you discover mold, do not disturb it, as that can release spores into the air. Contact a mold professional for testing and removal advice, and document the situation with photos and notes for your records.

When to Call a Professional

If the mold covers a small area, you might be able to clean it yourself with proper safety gear. For larger infestations, or if mold has spread into walls, ceilings, or HVAC systems, professional help is recommended. A mold professional can assess the extent of the problem and recommend safe removal methods.

In Mesquite, where the humid subtropical climate with hot summers and spring hail and thunderstorms can create moisture issues, staying alert to leaks is wise. Local water damage pros can help with water extraction, structural drying, and moisture mapping to find hidden dampness. They can also assist with drywall and flooring repairs after the mold is gone.

Finding the Right Help

When you need professional assistance, look for a service that specializes in commercial water damage and mold remediation. Ask about their approach to mold removal and whether they follow industry guidelines. They should be able to explain the process and provide a clear plan for restoring your building to a safe condition.

You can also consider a water damage inspection to identify the source of moisture and assess the full scope of the problem. Moisture mapping can reveal hidden damp areas that might not be visible. Addressing the root cause is essential to prevent mold from returning after cleanup.

Frequently asked questions

What should I do if I find mold in my commercial building?

First, do not touch or disturb the mold. Document the area with photos and note any water leaks or moisture sources. Then, contact a mold professional for an assessment. In the meantime, improve ventilation and fix any active leaks to slow further growth.

Can I clean mold myself in a commercial setting?

For small patches on non-porous surfaces, you might clean it with detergent and water. Wear gloves, goggles, and a mask. For larger areas or mold in drywall, carpet, or insulation, professional removal is safer and more effective. Always follow safety guidelines.

Will my insurance cover mold damage in my commercial building?

Coverage depends on your policy and the cause of the mold. Some policies exclude mold, while others may cover it if it results from a covered peril like a burst pipe. Policies vary, and your insurer decides what is covered. Review your policy and talk to your agent.
