He Opened the Wall to Find the Source of a Strange Smell and Was Stunned

This is the point where a mysterious household smell can turn into a much bigger discovery.

Opening a wall isn’t something to do casually, though.

Behind drywall could be electrical wiring, plumbing, insulation, structural components, or other materials that can be damaged easily.

Before cutting into a wall, it’s important to consider:

Where electrical wires may be located
Where plumbing lines run
Whether the wall is structural
Whether asbestos or other hazardous materials could be present in an older building
Whether protective equipment is necessary
Whether a professional inspection would be safer

A small inspection opening may reveal the source without requiring major demolition.
