Why Condensation Happens
Condensation forms when warm, humid indoor air hits cold surfaces like windows or exterior walls. The moisture turns into liquid water, which can feed mold if it stays wet.
Where Condensation Commonly Appears
- Window glass and frames
- Exterior walls and corners
- Cold water pipes
- Behind furniture on exterior walls
- Basement walls
How to Reduce Condensation
Lower Indoor Humidity
- Run bathroom and kitchen exhaust fans
- Use a dehumidifier in damp rooms
- Avoid drying clothes indoors
- Keep lids on pots while cooking
Warm the Surface
- Improve window insulation or add storm windows
- Open blinds to let warm air reach glass
- Seal air leaks around frames
- Add insulation where possible
When It Becomes a Mold Risk
- Condensation that drips or pools daily
- Water staining or peeling paint around windows
Quick Response Steps
- Wipe up condensation daily
- Dry window sills and frames
