Like that neighbor who drops by without warning, mold is an uninvited—and unwelcome—house guest. But mold isn’t just a problem because it can cause structural damage to your home. Mold spores can become airborne and cause respiratory issues and allergies. However, a mold inspection can help homeowners solve the issue before there’s a problem. The average mold inspection costs $650, but it may cost more for testing in harder-to-reach areas and in larger homes.

Maybe you’ve come home from vacation to notice unexpected water damage or a musty smell permeating your basement. Perhaps you’ve been wheezing for months and aren’t sure why. Either way, if your home is showing any signs of mold, it may be time for a mold inspection. 

Testing is actually the affordable part of a mold problem. It’s the mold remediation and removal that tends to cost thousands, but it’s important to take things one step at a time. The earlier you catch a mold problem, the more budget-friendly it will be to fix. 

In 2021, the average homeowner paid a professional mold inspector $650. Depending on the location of the mold growth and the size of your house, a mold inspection can cost as little as $150 or as much as $2,660

How Much Does Mold Inspection Cost Near You?

The cost of a mold inspection varies from state to state, but it generally falls in line with the cost of living. In cities with a higher cost of living, you’ll see prices teeter towards the high end. In areas with a lower cost of living, you’ll find prices on the lower side. 

Here’s a look at a few major cities:

Los Angeles$160 – $2,663
Portland, OR$160 – $1,400
Denver$155 – $2,230
Chicago$150 – $2,660
Providence, RI$150–$3,000

How Much Does It Cost to Do a Mold Inspection Yourself?

A mold testing kit can cost less than $40. You can use one if you notice any underlying reason for mold growth, like leaking pipes, cracked foundations, unsealed windows, or moisture in your home. You can also do an annual visual mold check before you call in a professional to save on costs, but none of this replaces a comprehensive assessment. 

Mold inspections require a professional, typically with knowledge of governmental standards like those set forth by the Environmental Protection Agency (EPA). They can properly analyze samples and determine the type of mold and the best way to treat it. Not to mention, many strains of mold are toxic and dangerous to remove without professional equipment. 

Rather than doing a DIY mold inspection, focus on preventative measures so mold inspection isn’t necessary. 

For example:

  • Good bathroom insulation can prevent rot and mold and costs an average of $1 to $5 per square foot.

  • You can try to divert rainwater away from your property by installing a drainage system, which costs an average of $3,959.

  • You can promptly repair leaks, which typically costs between $175 to $400.

  • You can repair rotted wood, which costs around $5 to $30 per square foot.

In some cases, you can stop a larger problem from developing if you properly clean mold when it shows up on a surface. Sometimes all it takes is some cleaning products and know-how. Even natural mold solutions work well, but always play it safe and call a professional as soon as you start to notice the signs. 

Mold Inspection Cost Breakdown

Though many mold inspection companies charge hourly, some do charge for separate services. Your inspector may specifically itemize an air test prior to a full inspection. This helps determine if your family is breathing in toxic spores and assess the danger of the situation. 

Air Test Cost

Testing your home’s air for toxic mold spores costs between $70 and $150. This is often included in a full inspection.

Inspection Cost

Mold can be easy or difficult to spot. If a mold inspector only checks obvious spots, the inspection can take as little as two hours. If they extensively check inaccessible areas, it can take as much as six hours. This dramatically changes the cost, but you can estimate based on the area.

  • High accessibility and visibility: Bathroom walls, kitchen walls, exposed foundation walls

  • Medium accessibility and visibility: Windows, window sills, fireplaces, chimneys, enclosed attic spaces near the roof.

  • Low accessibility and visibility: Air ducts and vents, crawl spaces, wall cavities (particularly areas between the drywall and foundation).

Commercial vs. Residential

Mold inspections in commercial spaces tend to cost more than those in residential homes, but only because commercial spaces tend to be larger.

What Factors Influence the Cost of a Mold Inspection?

You shouldn’t necessarily shy away from a high-priced inspection. Mold is tricky and hides in dark corners, cracks, and crevices. In the early stages, the problem may not even be visible to the naked eye, but a professional mold inspector will be able to do a meticulous examination. Costs are typically dependent on the number of samples needed, the square footage inspected, and the difficulty of the job.

Size of the House and Property

Since some mold inspection businesses charge by the hour, it will cost more to inspect larger homes and properties. Simply put, the more area a mold inspector has to cover, the higher your bill will rise. Sometimes, only a basement or attic will need to be inspected because of obvious water damage. Other times, an inspector will need to examine the whole home.

Number of Samples Needed

If you have mold in different parts of your home, an inspector will have to take numerous samples. They also do this to differentiate between types (think: white mold vs. black mold, which is notoriously dangerous). Some mold inspection businesses require a minimum number of samples.

Hard-to-Reach Places

Many mold removal businesses charge higher fees for hard-to-reach places. If a mold inspector needs to remove drywall or tile to access the area, there may be additional costs.

Type of Service

Some mold inspection companies charge by the service. For example, they’ll charge separate fees for a visual inspection and an air inspection. Others will charge more if they suspect black mold because it requires more protective equipment and care.

FAQs About Mold Inspection

When do I need a mold inspection?

You may want to get a mold inspection if you’ve had recent water damage or are experiencing the symptoms of a mold allergy. You may also want to get one when you’re purchasing a new home because you don’t know the home’s history.

What areas of my home are at risk for mold?

Mold tends to affect areas where water or moisture accumulates. This includes bathroom and kitchen walls, exposed foundations, windows and window sills, air conditioning and heating vents, fireplaces and chimneys, wall cavities, enclosed attic spaces, and crawl spaces that are hard to reach.

What happens if I have mold?

If it turns out that you do have a mold problem, you’ll need to have professional mold remediation. A mold issue is often deeper than what you see on the surface and does come with health risks. It should always be professionally treated.

How much does mold remediation cost?

If you do have a mold problem, it typically costs $1,120 to 3,330 to remove. This is why catching the issue before it becomes a problem is important.

Where can I find someone to check my house for mold?

Ask your friends and family for referrals or search online for reputable mold inspectors in your area. Be sure to check reviews, their website, online profiles, and social media accounts to see if they have a great reputation and a professional online presence.
