Stucco Surfaces Can Cause Problems if Not Replaced!


Stucco is a material found in many older buildings and homes, especially in Gladwyne, Villanova, and Berwyn. Because stucco is absorbent, if the material gets too wet or remains wet for a period of time, the flashing can fail and the stucco will have to be repaired. Homeowners can avoid the hassle of stucco remediation following a failure and replace the surface with improved siding products.


Hiring Cordeiro Construction with our expertise and diversity in stucco remediation on the Main Line, guarantees you correct and accurate solutions. Cordeiro Construction is capable of diagnosing the true problems and fixing just where they lie.

Cause: When it rains, the rain water carries with it contaminants that will get absorbed into untreated stucco. Rain water will also wash down contaminants from roof surfaces and windows which will be absorbed into untreated stucco. Every time it rains, the cycle repeats itself, not only accumulating deposits, but actually deteriorating the stucco.



Cause: If cracking is localized to specific areas it can often be linked to underlying damages from sources such as water. If the cracking is more general throughout, the stucco may have been improperly applied and/or done so in adverse weather. Cracking at dissimilar surfaces, such as windows, may be due to missing joint work or stop bead. Some structures may naturally experience movement in certain areas that exceed the strength and flexibility of normal, untreated stucco.



Cause: One of the top horrors of homeownership. If water is trapped behind the stucco, mold has an opportunity to grow.



Cause:Unsealed stucco will naturally age and start to deteriorate overtime. Pressure washing, improper mixing, poor installation, landscaping too close to the wall, heavy concentrations of water and more will expedite the decomposition of stucco.



Cause: Stucco contractors improperly installing stucco. When stucco extends below the grade, it creates two major problems. First, any water contained in the stucco that moves downward has nowhere to drain. Secondly, the stucco will actually pull moisture up out of the ground through capillarity (also known as capillary action, capillary rise, or wicking).



Cause: The natural porosity of stucco allows for excessive water saturation. The Northeast area where we are located experiences extreme weather conditions that can overwhelm stucco. This greatly increases the likelihood of damage and deterioration.



Cause: Efflorescence is a mineral salt deposit. These deposits are most commonly observed as a white-looking deposit on stucco. These water-soluble salts are present in varying degrees in the materials used to mix stucco so sometimes can be considered “normal”. But they also may originate at points where the stucco meets the soil or where heavy concentration of water is against the stucco. As the water gets absorbed into the stucco, it can dissolve some of the salts and these salts get drawn towards the surface. The water evaporates, leaving the salt deposits behind.


Cause: This is often overlooked during the construction phase. The window installer will blame the stucco contractor and vice-versa. Many times we find these areas to be the origin of large problems.


Cause: Staining appears because the high concentration of water is not properly being directed away from these key areas where lower roof lines run into the stucco wall. We continually find these areas to hold the greatest amount of underlying damages
