Visible water can have several possible sources. Use these steps to note what you’re seeing and decide when to contact a professional.

What to do first

Note where the water appears, when you first noticed it, and whether it followed rain or use of a nearby fixture. If water keeps returning or you can’t identify the source, a professional assessment can help.

Possible sources of basement moisture

Water may seep through a foundation wall or floor, come from a plumbing leak, or form as condensation. These are possibilities, not a diagnosis; the location and timing can help a professional assess the source.

When to get professional help

Contact a qualified professional if water is recurring, spreading, or unexplained. If water is near electrical equipment, keep away from the area and seek qualified help rather than inspecting or handling the equipment.

Choose the next service

If you suspect water is entering through the basement walls or floor, go to Waterproofing to reach verified providers. Don’t dismantle equipment or enter an unsafe crawlspace to investigate.
