Mold growth on drywall in wall cavity.
Some mold growth in buildings may be perfectly normal. For example, Ceratosystis and Ophiostoma are two molds that grow on lumber (sometimes referred to as lumber yard mold) and are frequently found growing on two by fours or other structural framing within buildings. These molds grow on the sap of wood and stop growing once the wood has dried. Although they cause black staining on the wood, they do not cause any structural issues. If black staining is found on wood, the mold inspector can take a sample and send it to the mold testing lab for analysis to determine if it is one of these molds.

It is very important (and some would say essential) that the mold inspection look for sources of moisture. Water is essential for mold growth. Without a source of water, you will not have mold growth. Consequently, if there is mold growth, it must be associated with a source of moisture. If this source of moisture is not found and eliminated, the mold growth will return and remediation efforts are of negligible long term value. The importance of looking for sources of moisture cannot be overstated and must be included.

Mold inspections are a subset of investigations called "Indoor Air Quality" (IAQ) investigations. These investigations look at the broader question: "What irritants are present in the air causing discomfort to the occupants?" If you are having a mold inspection because you feel ill when you are in a certain building or room, you might consider whether other irritants may be causing the discomfort and include these in the investigation.

Why Would I Need A Mold Inspection?
Pre and Post Mold remediation verification:  independent verification that potentially harmful mold exist prior to contracting to have mold remediated and independent verification that the contractor removed all existing mold after remediation. 
If you have an allergic reaction such as a runny nose, sneezing, or itchy eyes associated with being in a certain room or building.

To verify that sources of moisture have been successfully stopped and that no residual mold growth has been left after a known water and mold problem has been fixed.

To confirm that there is not an existing moisture or mold problem associated with a new building or home that you plan to rent or purchase.

If a specific water problem resulted in mold growth in a specific area, that doesn't necessarily mean you need a mold inspection. For example, if a roof leak has resulted in moldy ceiling tiles, then simply fixing the roof leak and replacing the ceiling tiles may be all that is necessary.

Common reasons for mold inspections include:
Pre-remediation minimum Initial testing samples: two (2) (one outside and inside air samples)
Post-removal minimum testing samples: three (3) (1 outside and 1 Inside air samples with 1 swab sample)

Note: these samples are immediately air mailed to approved laboratory for analysis and report.
How Much Do Mold Inspections Cost?
Mold inspection costs vary widely depending on the size of the property, extent of the mold inspection, number of mold samples, and other factors. We've heard of price quotes as low as $300 and as high as $3,000. While cost is clearly an important factor for most people, we recommend including other factors besides the mold inspection cost.
Why Do Some Companies Offer Free Mold Inspections?
We can only hypothesize why some companies would do this. Our feeling is they offer free mold inspections because they make $-money primarily from remediating any mold problems that are found. However, this puts them in a conflict of interest. If they make money from mold remediation, they will want to find mold problems during the free mold inspection. Otherwise, they won't make money. It may be best to have the Pre-mold and Post-mold assessment done by an independent inspector/assessor to resolve the potential conflict of interest if remediation is required.
At Sabreezz Home Inspection we only test for mold. We are not mold remediation/removal contractors thus, we have no potential conflict of interest. We only report the laboratory results. If mold is discovered, we can refer you to a remediation contactor.
If you select a mold remediation contractor to test and remove the molded material and remediate the source of the mold, it is prudent to have the post mold inspection/assessment completed by an independent inspector to assure that all of the harmful mold has been removed. .
