Should I Get a Mold Inspection Before Buying an Old House?

A general home inspector looks for visible signs of damage and major system defects. However, mold often grows in concealed areas like inside walls, under flooring, or in attics. Without specific tools like moisture meters and air sampling, these hidden colonies go unnoticed. A mold professional is trained to find these problems using specialized inspection techniques. This focused assessment is a necessary step beyond the basic evaluation provided in a typical home inspection.

Mold inspection costs often range from $300 to $600, depending on the home's size and the inspection's depth. This investment can prevent you from inheriting a significant problem that affects your health and the home's structure. If active mold is found, you can request the seller to remediate it before closing or ask for a price reduction to cover the cost. A professional report gives you concrete evidence for negotiations.

If the inspection report shows mold, you should consult with a mold remediation professional for a scope of work and cost estimate. Discuss the findings with your real estate agent to decide on a negotiation strategy. You may also need to involve a water damage pro to fix the underlying leak or moisture issue before any mold cleanup begins. Addressing the source of water is critical; otherwise, the mold problem is likely to return even after remediation.
