My gratitude goes beyond words for Jenni and her team. During this hard time, Jenni was compassionate, caring, listened, asked questions and ultimately her team took care of our situation timely and with excellence. It has been a lot for me and my family at the moment and there was no other company that could have done a better job. They were on time, very communicative, beyond kind and compassionate. Thank you Jenni and your team, you were exactly what we needed. Grateful for you! May God bless you guys.

Mold masters helped my sister Marie tremendously! She was diagnosed with some severe mold allergies and her health was jeopardized. She can’t stop talking about the owner Jenni and how much she helped her out. If I ever need a mold remediation I will be using mold masters.

Mold Masters basically saved my friend's life. My friend Marie got very bad news health wise and she needed this mold remediation ASAP. Jenni and her husband did everything in their power to fix her house. If I ever need to choose a company for mold remediation it will be them. I will always recommend them to everyone that mentions mold.

My wife hired mold masters to complete our mold remediation. My wife was given very bad news about her health and this company worked with us so we could provide a healthy environment for her to live in. They literally saved her life in more ways than one. I will recommend them to everyone I know. You are making the right choice by choosing Jenni and her team. Her and her husband are very compassionate human beings which is hard to find in this world.

UPDATE work has been completed and they are amazing and I cannot find the words to explain how they have worked with me during these tough times. I have never met an owner of a company who was this understanding and compassionate about their work.... I've hired them to do my mold remediation and I will do another review once completed. They have been so helpful and reasonable. Jenni and her husband are super compassionate and care about peoples health and well-being. Juan the inspector was super nice. Their office secretary is so nice and thorough as well.

When Mold Testing Makes Sense

Testing answers specific questions. It is most useful when you smell mold but cannot see it, after a leak or storm when you want to know whether spores are elevated, when someone in the home is sensitive to mold, or after remediation to check the work. If you can already see mold, the first step is usually fixing the moisture and removing the growth, not testing.

Types of mold testing

  • Air sampling: A pump draws a measured amount of air through a collection cassette. Indoor samples are compared with an outdoor sample.
  • Surface sampling: A swab or tape lift collects material from a suspect spot so the lab can confirm whether it is mold and identify the type.
  • Post-remediation verification: Testing after remediation to check whether the area meets the project’s clearance criteria.

Frequently Asked Questions

Mold testing gives you lab data when you need it. These are the questions we hear most from Dunedin homeowners and businesses about air and surface sampling.

Is mold testing necessary?

Not always. If you can already see mold, the first step is usually fixing the moisture and removing the growth. Testing is most useful when you smell mold but cannot see it, after a leak or storm, when someone in the home is sensitive to mold, or after remediation to check the work.

How is mold testing done?

Air samples are collected with a pump that draws a measured amount of air through a collection cassette, with an outdoor sample taken at the same time for comparison. Surface samples are collected with a swab or tape lift from a suspect spot. The samples go to a lab that identifies and counts the spores.

How long do mold test results take?

It depends on the lab. We tell you the expected turnaround when we book your appointment.

Can you test for mold inside walls?

Mold inside walls is usually found first through moisture readings and a careful look at the areas around it. Air sampling can help show whether spore levels point to a hidden source. If confirming growth would require opening a wall, we explain the options before anything is done.

How to Read Your Results

Your lab report lists the spore types and counts found in each sample. There is no single safe number for indoor mold. What matters is how indoor results compare with outdoor results, whether indoor samples show types not found outside, and whether the numbers match what the inspection found. We walk you through every result in plain language. For more, read What Do My Mold Test Results Mean?

Why Home Test Kits Fall Short

Most home kits show that spores are present. Since spores are present in nearly every home, a positive kit tells you very little. Kits usually skip the outdoor comparison and the inspection that gives results meaning. Read Are Home Mold Test Kits Accurate?
