Pressurized water lines concealed inside wall framing can develop microscopic pinholes caused by acidic water chemistry or un-reamed pipe burrs. Because water often sprays as a fine vapor mist inside insulation, months can pass before wet drywall appears.
Early Warning Signs Behind Walls
- Faint Hissing or Sizzling Sounds: Hearing high-pitched spray noises near hallway walls when all fixtures are turned off.
- Musty Odors and Humidity Spikes: Persistent moldy smells inside linen closets or under sinks.
- Blistering Paint or Peeling Wallpaper: Moisture migrating through gypsum drywall causes latex paint to bubble and baseboards to detach.
