Damage That a Leak Inside a Wall Can Make

Before we delve into the steps of leak detection, let’s first understand the potential havoc it can wreak. A leak inside a wall might seem unnoticeable at first, but if left unchecked, it can lead to extensive water damage. From unpleasant stains on your walls and ceilings to weakened structural integrity, the consequences can be costly and hazardous to your home’s health. 

What Are the Sources of Water Leak Inside a Wall?

Pipe Burst

Water leaking from walls can stem from different sources. It could be from:

  • Burst Pipes: Pipes can burst due to different reasons such as freezing temperatures, corrosion, or excessive water pressure. When a pipe bursts, it can release a significant amount of water into the walls, causing damage and potentially flooding the surrounding area.
  • Leaking Roof: Missing or damaged shingles, deteriorated flashing, or clogged gutters can allow rainwater to seep through the roof and into the walls, especially during heavy rainfall. Over time, this can result in water damage and mold growth inside the walls.
  • Faulty Plumbing: The leaking pipes, fittings, or fixtures may be slow and gradual, making them harder to detect initially. However, over time, they can cause significant damage to the walls and surrounding structures.
  • Condensation Buildup: Condensation occurs when warm, moist air comes into contact with cooler surfaces, leading to water droplets. In areas with poor ventilation, such as bathrooms, kitchens, or basements, condensation can accumulate on walls and eventually seep into the wall cavities, causing mold and mildew growth.

How to Find a Water Leak Inside a Wall: Steps

Leak in the wall

Here are the steps you can take to find a leak inside your wall:

  • Inspect Visually: Start by visually inspecting the walls for any signs of moisture or discoloration. Look for peeling paint or wallpaper, as well as any bulging or warping of the walls.
  • Touch the Area: Run your hand along the wall surface to feel for any dampness or cool spots. Pay close attention to areas near plumbing fixtures or appliances that use water.
  • Listen to the Sounds from the Walls: Sometimes, you can hear the sound of water running or dripping within the walls. Use a stethoscope or simply press your ear against the wall to listen for any telltale noises.
  • Use a Moisture Meter: Invest in a moisture meter to accurately measure the moisture levels within the walls. This tool can pinpoint areas of concern that may not be visible or detectable by touch alone.
  • Check for Mold or Mildew: Keep an eye out for any signs of mold or mildew growth, as these are often indicative of hidden water leaks. Mold thrives in damp environments and can flourish behind walls where moisture is present.
  • Inspect Exterior Walls: Don’t forget to inspect the exterior walls of your home as well. Cracks, gaps, or damaged siding can provide entry points for water, leading to leaks inside the walls.
  • Monitor Water Usage: Keep track of your water usage to help identify any abnormal spikes that could indicate a leak. A sudden increase in your water bill without a corresponding increase in usage is a red flag.

If It Rained, How Can I Find the Leak?

Wondering how to find a water leak inside a wall from rain? If you suspect the water leak is due to rain, you can do several things:

  • Examine the Exterior of Your Home: Begin by inspecting the exterior of your home for any visible signs of damage or deterioration. Walk around the perimeter of your house and carefully examine the walls, siding, and foundation for any cracks, gaps, or other abnormalities.
  • Check the Roof: Next, focus your attention on the roof. Look for missing or damaged shingles, as well as any signs of wear and tear. Pay close attention to areas where different roof planes meet, as these are common spots for leaks to occur.
  • Inspect Flashing: Check the flashing around chimneys, vents, skylights, and other roof penetrations for signs of damage or deterioration. Flashing is designed to prevent water from seeping into the gaps between roofing materials and structural elements, so any damage to it can compromise its effectiveness.
  • Clear Clogged Gutters: Clogged gutters can prevent rainwater from properly draining away from your home, leading to water accumulation and potential leaks. Use a ladder to safely access your gutters and remove any debris, such as leaves, twigs, or dirt, that may be obstructing the flow of water.
