Hidden vs. Visible Leaks — What’s the Difference

Hidden Leaks:

Occur behind walls or underground, making them hard to detect without professional help. These can lead to extensive structural damage if left untreated.

Visible Leaks:

Easier to spot but can escalate quickly. Examples include leaking faucets or showerheads.

Early detection is key to preventing costly repairs and maintaining your home’s integrity.
