How Often Should You Get a Mold Inspection?

Mold can grow silently behind walls, under flooring, and in air ducts without showing obvious signs. Because mold can spread quickly and impact indoor air quality, regular mold inspections are essential for detecting hidden mold growth before it becomes a costly problem.

But how often should you have your home or business inspected for mold? The answer depends on your property’s history, environmental conditions, and potential risk factors.

In this guide, we’ll break down when and how often you should schedule a professional mold inspection to keep your home or workplace safe and healthy.

When Should You Schedule a Mold Inspection?

1. After Water Damage or Flooding

Mold can develop within 24 to 48 hours of water exposure. If your home has experienced a flood, burst pipe, roof leak, or high humidity, an inspection is critical to detect hidden mold before it spreads.

✔ Schedule a mold inspection immediately after any water damage, even if everything appears dry.

2. If You Notice Musty Odors

A persistent musty or damp smell is often the first sign of hidden mold. Even if no visible mold is present, airborne mold spores could be spreading throughout your home.

✔ If you detect an unusual odor that won’t go away, a professional mold inspection can confirm the source.

3. If You or Your Family Experience Unexplained Health Symptoms

Mold exposure can cause allergy-like symptoms or worsen respiratory conditions. If you or a household member experience:

• Chronic coughing, sneezing, or sinus congestion

• Itchy eyes, skin rashes, or throat irritation

• Frequent headaches, dizziness, or fatigue

• Worsening asthma or difficulty breathing

It may be due to hidden mold. A mold inspection and air quality test can determine if mold is affecting your home’s environment.

✔ If symptoms persist indoors and improve when outside, mold may be the cause.

4. Before Buying or Selling a Home

A mold inspection should be part of any home sale or purchase. Sellers can avoid legal issues by confirming their property is mold-free, while buyers can prevent unexpected repair costs.

✔ Schedule a mold inspection before closing on a property to ensure no hidden mold issues exist.

5. If Your Home Has High Humidity or Poor Ventilation

Homes with humidity levels above 50% or poor airflow are more likely to develop mold over time. Areas like basements, attics, crawl spaces, and bathrooms are especially vulnerable.

✔ If you live in a humid climate or notice frequent condensation, schedule annual mold inspections to stay ahead of potential problems.

How Often Should You Have a Routine Mold Inspection?

Annual Mold Inspections (Recommended for Most Homes & Businesses)

For most properties, a yearly mold inspection is a proactive way to ensure that hidden mold is not developing behind walls, in ventilation systems, or beneath flooring.

• Best for: Homes with previous water damage, rental properties, and commercial buildings.

• Prevents: Mold-related health risks and expensive remediation costs.

✔ An annual mold inspection helps detect issues early, saving money on long-term repairs.

Bi-Annual Mold Inspections (For High-Risk Properties)

If your property is prone to moisture problems, bi-annual inspections (every 6 months) may be necessary.

• Best for: Homes in humid climates, basements prone to dampness, properties near water sources, or buildings with past mold issues.

• Prevents: Recurring mold problems by catching early warning signs.

✔ For properties with a history of mold, scheduling inspections twice a year can prevent costly damage.
