Start with the visible clues
Unexplained moisture, stains, water loss, odors, sounds, or changes in utility usage can all be reasons to investigate. The visible symptom is not always located at the actual source.
What to check
- Note where the symptom first appeared.
- Check whether the problem changes when fixtures or equipment operate.
- Look for moisture, staining, peeling finishes, damp soil, or unexplained water loss.
- Record changes in water or utility usage when relevant.
When professional detection may help
If the source is hidden, inaccessible, underground, beneath a slab, inside a wall, or otherwise difficult to isolate, a suitable professional detection method may help narrow the location before invasive work is considered.
Questions to ask a provider
Ask which method they recommend, what the inspection covers, what equipment may be used, what the expected scope is, and how pricing is determined. Confirm credentials and insurance directly.
