How To Detect Mold Inside Walls
You keep everything you can see in your home clean and sanitized, but have you considered what lurks beyond your line of sight? Your walls can house dangerous black mold growth even if you clean regularly.
Water damage can create a prime environment within walls for mold and mildew to fester.
Learn how to spot this hidden intrusion, keep it away for the long term, and prevent it from coming back.
What Causes Mold To Grow Inside Walls?
There are a few common reasons mold will grow inside walls that even attentive homeowners could miss out on.
A broken water pipe between walls allows water to pool and paves the way for mold growth. Even if you dried all the surface water, porous building materials will soak up the water and create a damp space for fungus.
A window leak also can lead to water exposure in between walls. A small hole will lead to a persistent leak letting water flow down the inside of your wall.
Humidity can creep into every available area of your home and take root. Inadequate ventilation will cause mildew to build up in all areas that are not sufficiently air-conditioned. People who live in hot and wet climates are most at risk of humid air causing mildew growth.
Poor insulation and siding are some of the most common reasons mold can grow within walls. When insulation becomes wet, it stops acting as a barrier and becomes completely porous. This is a typical chain of events: the roof has a small hole that leaks on the insulation, allowing water to pool inside the skeleton of your home, making the ideal conditions for mold.

Is Mold Inside Walls Dangerous?
In as little as 24 hours, mold can begin to grow in damp and dark areas. The dreaded Stachybotrys chartarum, or black mold, feeds off cellulose, which both wood and drywall are made of. Oxygen, water, food, and darkness are all that’s needed to make this take root. It is both easier and faster for mold to grow than you may think.
Black mold can cause hay fever symptoms in healthy people and lead to severe respiratory problems in people with preexisting conditions. Studies have shown black mold can cause sleep apnea, hives, rashes, and other common allergy symptoms.
Along with the sickness this fungus can bring, the structural integrity of your walls is threatened by mildew. Since mold eats cellulose, it slowly takes apart the building blocks of your home and puts it at risk of collapse.
Mold inside walls is very dangerous because it is so hidden. The spores hidden in crevices can be carried away by the air current of an HVAC system to infect all areas of your home.

How To Detect Mold Inside Walls
Keep all of your senses keen to pinpoint the location of the fungus.
Mold produces a unique musty smell that permeates out from its location. Sniff for a deep earthy smell like the forest floor. Get close to outlets and other holes to locate the source precisely.
Water damage and mold growth often go hand in hand. Look for signs of water damage along your walls. Any discoloration from brown to yellow to black is a serious warning sign.
Any slimy or fuzzy growths appearing is a sure-fire sign of a colony within your walls. Any color from yellow to green to purple to red to black is a bad sign.
If you notice condensation on your walls or they feel wet to the touch, immediately get help. Do your best to dry any surface water; you can attempt to clean faster than mildew can grow.
Peeling and cracking
Wallpaper and paint should never peel or crack. Bulges and bubbles are a sign of excess moisture slowly building up over time. If you see your walls warping or twisting, you have water damage and will need to bring in an expert to properly dry and prevent a mold infestation.

How To Remove Mold Behind Walls
The most challenging part of cleaning behind a wall is that you will have to tear it down in order to access the affected areas. It is best to work with professionals to avoid cutting through any electrical wiring or plumbing piping.
Should you manage to access the interior yourself, follow the same steps to remove mold from wood flooring. Create a cleaning solution of bleach and water and work in the mixture until you lift the mold completely and you cannot see any remnants.
Lastly, you must fully dry the area. Start with a cloth to remove surface water, then run a dehumidifier for at least 24 hours so that the site will dry all the way through.
