Mold Testing and Solutions Done Easy

PureLiving – we are China’s mold experts with nearly 100 completed mold testing and remediation projects in homes, schools, and offices.

Mold Testing Services:

1. Mold Inspection (1400-2000 RMB) – this is a walkthrough inspection to look for mold in likely places and also detect water damage and sources of moisture, which is how to control mold. This is best when you know where mold is or where water damage has been, and you want to know whether the water problem has been stopped, identify the source of the moisture, and how to stop the water problem.

  • Gather additional background information to confirm/deny hypotheses on mold source and extent
  • Conduct visual and odor examination of suspected mold
  • Examine property for evidence of water intrusion and damage
  • Measure and document relative humidity and temp throughout rooms and outdoors for comparison purposes
  • Test moisture levels in walls and suspected mold growth areas to assess water damage
  • Survey activities around suspected mold areas that may be drivers of mold growth
  • Generate report of documented findings and action plan, including remediation recommendations

2. Mold Testing (600 RMB per room, minimum of 3 samples; 500 RMB each for 4 or more). This involves taking 100L of air and then counting the mold spores within that sample of air and determining whether there is active mold growth in that area.  This is most useful when you suspect mold in an area but cannot see it, if you need proof to confirm/deny whether mold is growing (to provide a landlord, for instance), or if you want to quantify how bad the problem is. It is especially good when an individual is suffering from symptoms and wants to try to rule out mold as a cause since it provides useful information to provide an allergenist so he/she knows what types of mold exist in your environment.  Finally, formal mold testing is a must when trying to get landlords to acknowledge that there is a problem.

Testing includes analysis, amount of mold growth by type, and a report of the results. Mold testing tells you if there is mold growing, what type it is, but not why or what the source is, for which the inspection is necessary.  We are the only company in China (to our knowledge) capable of doing this and we send our samples to be analyzed by a microbiology lab in the US.

3. Mold Remediation Solutions. If we find mold growing, once we’ve figured out what it is, assuming it’s not a major structural issue (leaking pipes, water intrusion, etc), we will give you a step by step process of how to fix the mold. You can choose to either do it yourself if it is a small project, or we can do it for you. Typically, the various parts of a mold remediation can include:

  • Containment of the area to prevent cross-contamination to other parts of the apartment
  • Cleaning with an industrial HEPA-filtered vacuum to remove spores
  • Physical removal with a mold killing agent
  • Fogging with chlorine dioxide, a fungicide that quickly will dissipate so no harmful byproducts
  • Painting with anti-mold paint
  • Providing N95-rated masks that filter out 95% of all particles smaller than 0.3microns
  • Retesting if you’d like to verify that there are no unhealthy levels of spores remaining

Note, all services have a 400 RMB technician sampling/transportation fee unless conducted as part of a larger testing project.

We also provide solutions for mold remediation such as:

  • Dehumidifiers – key way to remove moisture
  • Anti-mold sachets – hang in a room and inhibits mold and deodorizes in up to a 15m2 space
  • Humidity monitors – inexpensive way to determine how high humidity is in a room
  • HEPA vacuums to safely remove settled mold spores
  • Anti-mold paint and paint additives – use to keep mold from returning
  • HEPA filters – to remove spores from the air
  • N95-masks – stops mold spores and 95% of all particulates 0.3 microns or smaller

Mold Testing and Solutions Done Easy

  1. Jhake Turner says:

    If you’re in doubt of any unpleasant growth in your house, you should simply assume there is a problem whenever you see mold or smell mold odors. Testing should never take the place of visual inspection (which is recommended) and it should never use up resources that are needed to correct moisture problems and remove visible growth.
    People used to think that molds were harmless but it isn’t. The fact is, some molds produce a toxin called aflatoxin (toxic and among the most carcinogenic substances known) that causes illness and death in people.
    Sometimes, mold growth is hidden and difficult or hard to locate and find. In such cases, carefully conducted sampling and visual inspection may help determine the location of contamination. However, mold testing is rarely useful for trying to answer questions or inquiries about health concerns. For more information, see mold testing services

  2. Leland says:

    Awesome tips!!!! thanks for these. people need to be more aware of moisture involved in their everyday lives.. best bet though would be to contact a mold remediation service to help get CUSTOMIZED help.. there are a lot of variables to keep in mind :)

    • Louie Cheng says:

      Moisture is the only variable that we can control in an indoor environment (though we can reduce the amount of “food” sources that we make available to mold), so finding and stopping the moisture is the most important step.

      We actually do remediation as well and have completed over 150 mold inspections and remediations in Shanghai and Beijing, ranging from simple “I smell mold — is it there and how unhealthy” to a major structural repair and mold removal project for the Canadian Consul General.

  3. Wow this is a great guide on mold test. Thank you for being so extensive on your article!
