Mold Testing Services

Our certified professionals have many years of experience providing a range of inspection and testing services, which will help you gain information on whether your property has a mold problem or not.

  • Sampling

    When testing for mold in Bethesda, we perform two types of sampling. Mold releases spores into the air, which affects air quality, so the first type is air sampling. We identify a part of your house where there is the possibility of mold growth and take air samples. We also take air samples from outside your property to help in comparing the results.

    The second type of sampling is surface sampling. In this, we identify spots on the walls or floor where we suspect there is mold or mildew growth and we take samples directly from these surfaces. The samples are taken to our certified laboratories for testing. Once the laboratory tests are completed, you will be given detailed results.

  • Mold Inspection

    Our mold inspection service in Bethesda is here for you when you suspect bad air quality in the house, when your family suffers from colds and congestion, or when you have any other reason to suspect black mold growth. Our team of experts is sent to your property and inspects all areas of concern. Depending on your needs and the particular situation, we can collect air samples which are then sent to the laboratory to be checked. A full report is issued to you within days, so you can get started with the mold remediation process as soon as possible. Mold remediation includes removal of affected materials, cleaning, sanitizing, and additional preventative activities.

  • Moisture Detection

    Mold grows and thrives in places where there is moisture. Therefore, we help identify places where there are leaks and water in your home. We use the latest techniques and technologies to identify these areas.

DIY Mold Testing Kit vs Professional Mold Testing

When faced with concerns about mold in your home or property, the decision between using a DIY mold testing kit and seeking professional mold testing services is a critical choice that can impact both the accuracy of results and the effectiveness of subsequent remediation efforts. While DIY kits offer convenience and cost savings, professional mold testing provides expertise and comprehensive analysis. This comparison delves into the nuances of DIY mold testing kits versus the provided offered by professionals, exploring the advantages and limitations of each approach to help individuals make informed decisions when it comes to assessing and addressing mold-related issues in indoor environments.
