Does Your House Have Mold?

Of course it does! Every house has mold in the air. The air you breath every day, even outdoors, has mold. The concern is if the air in the interior of your home has a higher mold count than the exterior air around your home. Mold testing can let you know if you have a mold issue in your home.

What is Mold?

Mold is a fungi. Spores are the reproductive part of mold and are transferred through the air. Spores are present in the air you breathe, whether indoors or outdoors. In order for mold to grow, there need to be conditions conducive to growth. These conditions are moisture, temperature, and a food source. However, moisture control is the most critical factor for controlling mold. Relative humidity in the home should be kept below 60%. Any water leaks in a home should be cleaned immediately, as mold growth will start in as little as 24 hours.

Why is Mold a Problem?

There is no conclusive data as to the health effects of mold. However, it is suspected that immuno-compromised people, young children, and seniors are more susceptible to health effects caused by mold. The most common health effect is as an allergen. However, mold also produce a substance called mycotoxins, which are suspected of causing adverse health effects in humans. A mold inspector is not qualified to give health advise relative to mold. If you are concerned about potential health issues related to mold, please consult with a qualified medical specialist. For more information on mold, please visit the following:

What is Mold Testing?

Generally, mold testing is air sampling. Two air samples should be taken at the exterior of the home. Additional air samples will be taken on the interior of the home. An air sample is needed for every 1000 square feet and at least one for every level of the home.

If there is visual evidence of moisture damage or mold, then the inspector should take additional samples of the moisture damage or visually suspected mold. This usually happens in the form of a tape sample or a swab sample. A sample should be taken for each visually different color of suspected mold.

These air and surface samples are then shipped to a lab. Lab technicians then evaluate the samples and provide an electronic report within 1-2 business days of receiving the samples.

Why Use Tanque Verde Home Inspections for Mold Testing?

Tanque Verde Home Inspections does not offer remediation services. Therefore, we do not have a conflict of interest. You should not go to a remediation company to have your home tested, as they have an interest in selling remediation services. Additionally, you should have your home tested by an independent third party prior to and after any remediation services.


How Much Does Mold Testing Cost?

Generally, a certain number of mold samples will be included in the base cost. Additional samples will cost extra. Tanque Verde Home Inspections includes up to 5 samples in a mold test. This includes two outdoor air samples (windward and leeward sides of the home), two indoor air samples, and one surface sample (if visually suspected). If the home is greater than 2000 square feet, has multiple levels, or has suspected mold in multiple areas, additional samples at an additional price will be required.
