Signs of Water Damage in Walls

From a busted pipe to a heavy rainstorm, there are many ways water can creep into your home. Unwanted water can not only cause extensive damage to your house’s structure, it can also become a breeding ground for mold and endanger the health of your home’s inhabitants. For this reason, its crucial to identify water damage in your home as quickly as possible. 

Signs of Water Damage in Walls

Not all water damage is easy to spot. Water leaks often occur behind walls and other places that are not immediately noticeable even to the home’s residents. Water damage that goes unnoticed can cause extensive structural harm leading to costly repairs. This means that time is of the essence when it comes to identifying water damage and locating its source. 

Wondering how to detect signs of water damage in walls in your home? Here are some things to look for.


Discolored spots on your walls or ceiling can be a clear sign of unwanted moisture in your home. These stains occur when water is absorbed into sheetrock or drywall, so if you notice new or expanding stains on your walls, it’s time to call a professional.  

Peeling Paint

Excess moisture behind your walls can cause paint and wallpaper to peel, flake or bubble. Inspecting your walls for changes in texture can help you identify a buildup of moisture behind them.

Strange Smells

When building materials like wood and drywall absorb water, they become vulnerable to mold growth. Mold emits a distinct odor, so if you begin to detect a musty smell in your home, it could be a sign of mold growth within your walls. 

Visible Mold

Another sure sign of water damage is the appearance of mold. Mold thrives in damp environments and can start to grow in as little as 24 hours. Within a home, mold usually appears in small black, grey, brown or orange blotches. 

Soft or Swollen Drywall

Moisture-damaged drywall will feel soft and spongy to the touch. This is commonly referred to as drywall rot and is an indication that extended water exposure has caused the material to deteriorate.
