Molds are fungi that can be found both indoors and outdoors, all year round. Although some forms of mold are extremely dangerous or even toxic, most molds are relatively harmless. However, large concentrations of indoor mold can cause odors, health problems[1] and, in some cases, structural damage to wood. An inspection and testing will determine how much mold is present in a home, and where.

Typical costs:

  • Do-it-yourself mold test kits[2] are available online or at home improvement stores for $5-$100. With a kit, you take a sample, place it in growth medium (like a petri dish) and wait 48 hours to see if mold grows. However, to learn exactly what types of mold are present you have to mail the kit to a lab, which adds shipping costs plus testing fees of $30-$150 per sample, depending on the level of identification and the type of report and consultation provided.
  • A professional mold inspection of a typical family home runs $200-$600, although larger homes (5,000-10,000 square feet or more) can be $600-$900 and up. In extreme cases, the inspector may cut open the walls for what's known as an invasive inspection. The total additional cost will depend on the extent of the hidden mold and how much work is required to discover it.

What should be included:
  • Several different types of mold (also called mildew) are almost always present both indoors and out; they usually are benign and only grow large colonies where there's moisture. Because do-it-yourself test kits can become contaminated before use, does NOT recommend the kits it evaluated. And it's usually not necessary to identify the type of mold[3] growing in your home, according to the Centers for Disease Control (CDC); just remove the mold without testing it.
  • Some companies offer both mold inspection and remediation, but most experts recommend using different contractors for these services. A full mold inspection of a typical home takes about 2-5 hours. The inspector will visually evaluate the structure, both
Additional costs:
  • There can be fees for additional paperwork for an insurance claim or other circumstances; if you need specific documentation, be sure to ask if it's included in the quote.
Shopping for mold inspection:
  • There are a number of organizations offering mold "certification" -- some require only a fee or an online course to qualify as a certified expert. Check to be sure that your inspector is certified by a group requiring training, experience and testing. Referrals are available from the American Council for Accredited Certification.

We were very happy with the service tailored to our needs and how expert they were. We liked that they had advanced degrees in Microbiology.
We received a detailed scientific mold analysis report which was easy to understand.

Type of Test:: Mold Inspection with Remediation Plan
I used On-Site Mold Analysis, they came to my house the following day, and took 6 surface samples, and 2 air samples, they did a lot of moisture readings throughout my house and took a ton of pictures, which were used in the report they sent to me, the very following day. It was exactly what I needed for my insurance company, and it gave me a clear "blueprint", of what was wrong in my house, what wasn't invaded by mold, and how the remediation crew should proceed.
I felt like they really knew what they were doing, considering they have there own lab and that the report they emailed me, the very next day was 38 pages long...
All and all they were not the cheapest when I was shopping around, but they were very close to it, and they told me what to look out for, when I continued shopping around. I felt like they're trustworthy, so that's why I went with them.

Type of Test:: whole house
I used a company local to my area and was charged for testing two areas of my home which is about 1600 sq ft. I asked for the whole house to be tested but was told that it would be cheaper just to test the two areas because if it was in the house it was in the whole house. Was informed of excessive amounts of mold in my brand new 2013 home never lived in before order just for us. Currently going through a claim through my contractors insurance company and am hoping they just pay me and don't have to sue them for millions more than I'm asking for but hard headed insurance companies never learn so we'll see.

Type of Test:: Air Sample
I had a feeling that mold was growing in my house but had no proof . There was this smell that I described to a friend, she told me it sounded consistent with her experience of having mold in her basement. She referred me to a company named Eradicator Mold Remediation Services in our state of New Jersey. I gave them a call, scheduled an inspection, the cost was $175.00 The experience was professional and rewarding as the results that I received a few days later from the tests was conclusive of my fears. Best money spent.

Type of Test:: Mold Inspection
I refer my clients a compnay that does a thorough physical inspection for mold, and the cost is usually around $150. They are very thorough and very good. They also offer testing, but most of my clients learn far more from the inspection than they could from test results with no waiting for the results and at a fraction of what testing could cost. Great service:

Type of Test:: Full Testing
I used a company called Asela Cleanup and Restoration, they are certified mold inspectors and they charged me $345 for the test results from the lab and a full report with an analysis. They helped me understand the results because the lab is really confusing. I found that testing can range from $300 to $1200 depending on who you use - I called around. I was told though that there are a lot of people who do testing without certification, so be careful. If you need someone, - they are in California.
