Condensation

Start with the question that matches what you see.

Separate indoor-surface condensation from failed glazing seals, then reduce moisture without hiding leaks or damaging ventilation.

Use temperature and relative humidity to estimate dew point and understand why windows, pipes, walls, and garage surfaces get wet.

Locate the wet surface before choosing a humidity fix or window repair.

Distinguish outdoor dew from indoor humidity and water leaking through a window.

Find out whether a covered window has a different moisture pattern from an exposed one.

Compare droplets along a cold pipe with water concentrated at a fitting.
