When Is Testing For Mold Necessary?

Posted on

Testing for mold is a good way to stay ahead of a problem that can damage a house and make it unhealthy for its occupants. When is mold testing necessary, though? Homeowners should consider testing for mold in these six situations. 

After Water Damage

If any kind of water damage has affected a building, testing is prudent. Flooding is a common source of mold problems, especially in humid regions where it can be hard to dry a house out just by opening the doors and windows. Likewise, water leaks can trigger mold problems. If there was a sewer or other drain backup, you should also test for mold issues.

Unexplained Respiratory Problems

Mold testing can also uncover the source of health issues in a house. If someone in your household has been coughing or wheezing for no apparent reason, mold could be the cause.

Notably, there are other potential sources of breathing troubles. Particularly, radon exposure can trigger similar symptoms. You should consider other types of testing in addition to checking for mold if anyone in your house has unexplained and chronic respiratory concerns.

Following Remediation Work

Never assume that a mold remediation project solved all of the problems in a house. After a remediation contractor has wrapped up a job, schedule testing. Use a different company to perform mold testing so you can get an independent opinion. You want to be sure that your investment in fixing the problem has paid off.

Buying a House

Many people schedule home inspections when they buy houses. However, these only address cursory issues. Unless the mold is visible, there's a good chance that a home inspector will miss the problem.

Particularly if you're purchasing a house in a humid part of the country, mold testing is wise. Also, you should consider it if the house has an older HVAC system. Older units frequently struggle to keep up with dehumidification needs. If you're going to have to replace an A/C setup, you want to know that before you pay for a house.

Renting Out or Selling a Home

Folks selling or renting out houses face liability issues if they fail to disclose the presence of mold. Professional mold testing will provide documentation that you made efforts in good faith to prevent such problems.

High Humidity Levels

Especially if you've invested in good insulation and climate control in a house, the humidity levels should be reasonable. If they're not, then testing for mold may help you track down potential sources.
