At Building Block Home Inspections, the inspector will conduct a mold inspection especially in areas of the home that have poor air circulation or a potential for water intrusion. The home inspection report may advise you to seek a qualified person in mold remediation if mold is found. Mold spores are everywhere and they are just looking for a place with the right conditions to grow, roofing materials like wood shingles or shakes are prone to perpetuate mold growth on the north and east side of the home because they usually don’t have a chance to dry completely. The mold spores contact the wood shingles, and grow in the wood, then into the sheathing, rafters, joists, then into the walls if not addressed. Any roofing material that allows moisture to the sheathing underneath will allow mold spores to grow. BBHI’s thorough mold inspection uncovers all such instances.
Mold Inspection FAQs
Molds are created due to the breaking down of dead organic matter that deteriorates and provides tiny spores, ie fallen leaves or trees. The spores float through the air and will attach or stick to sources of organic material which are moist like wood or drywall, carpets and carpet padding; these are a good food source for mold.
The conditions that mold can grow: between 32 and 95 °F (0 and 35 °C), available moisture, food for the mold spores (for example, dust or dander), and warmth.
The first step in mold inspection is to non-intrusively determine if mold is present by visually examining the premises. If mold is actively growing and visibly confirmed, sampling for its specific species is unnecessary. Intrusive observation is sometimes needed to assess the mold level. This includes moving furniture, lifting (or removing) carpets, checking behind wallpaper or paneling, checking ventilation ductwork and exposing wall cavities. Detailed visual inspection and the recognition of moldy odors can also be indicators of mold issues. Efforts should focus on areas where there are signs of liquid moisture or water vapor (humidity), or where moisture issues are suspected.
Relative humidity levels above 70 percent appear to be optimal for fungal or mold spore growth. A lower relative humidity level reduces the rate of mold growth as the mold goes dormant but does not stop growth and development entirely. In fact, with at low relative humidity levels, there is increased spore release into the air.
In most cases, it is not practical to test for mold growth in a house unless you are having respiratory effects. There are no standards for “acceptable” levels of mold in a dwelling, and when testing is done, it is usually to compare levels of mold spores inside the house with levels outside the house. Where conditions exist for mold growth it should be monitored on a regular basis.
