Expect all these benefits if you work with a certified mold testing specialist. As you get in touch for mold services, let's brief you on all there is to know about mold testing.


How Exactly Is Mold Testing Done?

How an expert executes mold testing depends on the test and preferred strategies. There are several mold tests. Here is a breakdown of how mold testing happens.

Step 1: Visual Mold Inspection

A visual mold inspection gives an overview of the situation. Our team will look for visible signs of mold infestation, like wall discoloration. We will also check specific places like behind the drywall, wallboards, fridge, under sinks and carpets, ventilation ducts, and windows.

Step 2: Air Sampling

This step involves testing the air inside your home or office. We use advanced spore traps to collect organic and inorganic matter in the air, like pollen and mold spores. We will also collect from the air between the walls for mold spores. Air sampling is necessary because mold spores are invisible to the naked eye. The air samples go through lab analysis to determine the mold's presence and the issue's severity.

Step 3: Surface Sampling

This is where our experts take samples directly from suspected or known mold growth areas for testing. Moisture and leak detection is also categorized here. The collected samples are then dispatched to an independent testing lab where a specialist identifies the mold strains and their extent. Air and surface sampling happen together or independently.


How Long Does Mold Testing Take?

Mold testing takes a couple of hours. We will need at least an hour to collect samples and conduct visual inspections around your property. However, the final test results will take a few days, depending on the lab's efficiency and workload. After that, you will get a comprehensive mold report after two business days. That is after sample collection and analysis of the lab report. For quick mold testing, you can never go wrong with our certified mold detection experts.


Professional Mold Testing Cost Range

The average cost for mold testing is not constant. It varies from $250 to $400 for a small to medium-sized house and between $700 to $1000 for larger properties. That tells you the size of your house and the workload involved will influence the mold testing cost. The pricing also differs based on the region and technology employed. For example, the mold inspection cost in one city may not be the same as in other nearby cities.


Main Signs of a Professional Mold Testing Company You Can Rely On

Mold detection can be challenging, especially when the infestation is still in its early stages and there is no visible mold damage. That's where an expert company comes in. Look out for the following signs to have an assurance of outstanding services.

Are Mold Inspection and Testing the Same Things?

Mold inspection involves looking for evidence of mold growth and its source. The inspector may also look for past mold growth evidence to determine the cause of the current mold growth. On the other hand, mold testing is where air and surface samples are used to determine the type of mold present in an area. While these terms are not the same, mold inspection is the first step during mold testing/sampling.


FAQs about Professional Mold Testing

With many homes facing mold infestation issues, a lot needs to be addressed. Here are quick answers to critical questions homeowners ask every day.

Can a mold testing company tell where mold is coming from?

Whenever there is mold growth, it means there is a source of water feeding the mold. It wouldn't be happening otherwise.

By analyzing the mold type and its characteristics after sample collection, we can also tell the specific source of the mold.

Protect yourself from mold testing scams by researching your company of choice. Extensive background research and looking into elements like certification, registration, experience, and testimonials will help you make a wise choice.
