If you’ve ever had stucco water damage in your house, you know how frustrating it can be. You might have spent years trying to repair the wall and now find out it won’t hold up. Or perhaps you’ve already removed part of the stucco from the exterior of your home, only to discover some decay inside. And what about mold? Or mildew? There are so many signs that your house could use some help when dealing with stucco water damage—and they’re not always visible! And while the most common reasons are listed below, there are other reasons that this type of damage can occur. For example, stucco can be damaged by fire, flooding, or even by not being adequately maintained.

Stucco water damage?

Stucco is a type of exterior wall covering that can cover the outside of houses. It’s made of sand, cement, lime, and water. Stucco comes in several different styles:

● Smooth (natural) stucco is made from only sand and has a smooth finish that allows it to blend into your surroundings; this type is most often used on older homes or those not being painted regularly because it tends to wear faster than other types of stucco.

● Rough (artificial) stucco uses more cement in its construction than rough natural stuccos but still contains some raw materials such as lime or clay; these types tend to be more affordable than smooth ones because they require less labor time during installation—and since they’re cheaper overall you may find yourself wanting something else instead!

Signs That Your House Is a Walking Stash of Stucco Water Damage.

Window Frame Rot

Window frame rot is the most common type of stucco water damage. The reason for this is simple: windows are the most common place for water to seep in and cause problems. Window frames are made of wood, which can rot over time if exposed to moisture or other elements that cause decay. This can happen even if you don’t have any cracks in your home’s exterior stucco—the wood itself has been damaged by repeated exposure to rainwater, which causes it to crack and absorb moisture from inside its pores (which isn’t good).


Efflorescence is a white, powdery substance that appears on the surface of the stucco. It’s caused by water leaking through the stucco and into the mortar between the bricks. You may notice efflorescence after water damage in your home for a while—it can take up to six months to complete this process. Still, it’s worth checking for any signs of efflorescence when you’re inspecting an area recently damaged by water leakage!

Wood Rot in the Attic

Wood rot is caused by moisture and insects. It can cause structural damage to your house, even if you have good roof and wall systems protecting it from the elements.

Wood rot is typically found in attics that are poorly ventilated or have no way for air to move around inside them, so ventilation should be considered part of any home repair project that involves adding insulation or changing the location of an existing attic hatch. In addition, wood rot often occurs when moisture from outside seeps into an attic through leaks in the walls or roof (or both). The result? Rotting rafters full of molds and mildew—and possibly even structural damage!

Mold and Mildew Growth Inside Your House

Mold and mildew are a sign that your house has been water damaged. Both species of mold can cause health problems, allergies, and asthma. Mold spores can be toxic to pets and children if inhaled or ingested. The spores may also irritate people with allergies or respiratory issues.

Sagging Roof Decking

Sagging roof decking is another warning sign that your house may need to be stuccoed. Roof decks are made of wood, and they usually get wet when it rains or when there is a leak in the roof. When this happens, the moisture causes mold to grow on your decking boards and begin to sag under their weight.

When you have sagging roof decking, it’s time to call an expert who can advise you on how best to fix this problem. You might want to consider having a professional install new boards or replace them altogether so that your home doesn’t suffer any further water damage due to leaky pipes or faulty plumbing systems throughout its interior walls.

Stains on the Interior Walls

Stains on the interior walls are a sign of water damage. Leaks in the roof or plumbing usually cause them, but they can also be caused by condensation on the walls.

If you have stains on your ceiling or wallpaper, it could signify that mold and mildew are growing behind them (and possibly even behind other things in your home).

Buckling Stucco

Buckling stucco is caused by water damage, which can lead to other problems. When buckling occurs, the walls appear to bend inwards or outward. This may make it difficult to see what’s happening behind an interior wall.

Discolored stucco

Discolored stucco signifies that water has seeped into the wall and damaged the plaster. This can occur due to condensation, but algae and mold growth also cause it. If you see discoloration in your stucco, don’t ignore it! It may be time to call a stucco repair expert in Canada,to look at your home before anything else happens—especially if you notice other signs of water damage, such as mold growth or mold spores floating through the air (yes, this does happen).

Cracks and chips

Cracks and chips in your stucco are an indication of water damage. The cracks can cause the house to lose structural integrity, which could lead to more severe problems like a leaky roof or foundation settlement. Water damage is also an issue that may be difficult to repair on your own, so if you see these signs in your home, get help from a professional contractor immediately!

Final Words

If your home’s stucco begins to exhibit any of these signs, the time to act is before the conditions worsen and your home requires major repairs or reconstruction.
