My Advice….

·       Hire a test provider who specializes in Mold Measurements and who is certified by the EPA to do so.

·       To Avoid conflicts of interest do not hire a test provider who also offers remediation services.

·       In our opinion the best measurement method is by way of an air-o-cell (particulate counter) and lab sample that is sent to an EPA certified lab for analysis such as EMLab P&K.

My Preferred Mold Tester is:  
        A Healthy Home


An Excellent question but not so easily answered.  We live every day in a sea of mold spores, there is no escaping them.  Some of those spores if allowed to grow in a home can be toxic and are reported to cause health problems although there are conflicting opinions amoung experts in the severity of the problem.  Some species affect some people all of the time and other people none of the time.   One thing is for sure; if there is mold growth in a home located in Colorado there is most likely an underlying problem associated with water.


Mold testing usually is not performed unless there is ample visual evidence that a problem exists via the General Home Inspection or the potential new owner has a known personal mold allergy.  Mold testing is a subjective decision.  There are no hard core health hazard guidelines given to us by the EPA consequently the health hazard associated with test results are often subjective. The decision is ultimately yours to make but here are some helpful thoughts;

·       If you have medical proof that you are allergic to one or more particular mold species you may want to test for mold but beware testing may not provide you a definitive answer. (See Testing) If you are concern about mold you might also want to think about implementing HEPA filtering, Electrostatic filtering or maybe buying a home with hot water heat; in an effort to minimize the redistribution of air within the home.

·        If you enter a room and it smells of dirt or has a musky odor but you cannot see any indication of mold, you might want to test for mold if the order can not be indentified or located.

·        If you visually see mold growing anywhere within the home then of course there is a mold problem but you still may want to test to determine the type and magnitude of the mold problem.  Mold can and will migrate to areas not visible.  Mildew on the other hand may not warrant mold testing.  Mildew is a common problem on tile around bath-tubs and showers and is easily removed, however if it has migrated to walls outside the shower or tub area there is most likely a bigger problem.


Testing, remediation work and who pays for it are up for negotiation.   Mold testing and remediation work can be expensive relatively speaking.  The presence of mold is usually an indication that there is another problem within the home that is causing mold growth.  Therefore one should seriously think about whether they want to get involved with a home that appears to have a severe mold problem.


Test results should provide evidence that the mold count inside is less than or equal to the mold count outside in type and quantity.  Mold tests are statistically based on a sampling of the air within the home in comparison to an outside sampling taken in the same time frame.  If there is a gross mold problem within the home it usually is easy to identify but if the problem is subtle a quagmire can arise due to an under sampling of the air.  That is to say; sometimes one cannot tell from the raw measured values if inside measured levels match outside levels, in which case you must rely on your test provider to give you an informed professional opinion.
