Leaking Pipe: Causes, Fixes & When to Call a Plumber
A leaking pipe should be addressed within 24 hours. Apply a pipe repair clamp or plumber's tape as a temporary fix, turn off the water supply to the affected section if possible, and call a licensed plumber for a permanent repair.
What Causes Leaking Pipe?
- Corrosion and age weakening pipe walls
- Joint failure from water pressure fluctuations
- Physical damage from drilling, nailing, or freezing
- Tree root pressure on exterior pipes
- Improper pipe installation or incompatible materials

- 2Dry the pipe and apply epoxy putty or pipe repair tape as a temporary fix

Frequently Asked Questions About Leaking Pipe
- Mold can begin growing within 24–48 hours of water exposure. Structural damage to drywall and framing accelerates after 48 hours. Even a slow drip behind a wall can cause significant damage within weeks.
- No — pipe repair tape and epoxy putty are temporary measures only. They will fail under normal water pressure within weeks to months. A proper compression fitting or pipe section replacement is required for a permanent fix.
- Plumbers use acoustic listening devices, thermal imaging cameras, and pressure testing to locate leaks inside walls or under slabs without unnecessary demolition. This non-invasive leak detection typically costs $150–$400 and prevents larger repair costs.
