Ensure Quality of Structure

Causes of Poor Stucco


Many lawsuits have been documented due to wrong or poor application of stucco. Stucco is a porous material that is designed to absorb water. It is usually applied in three coatings known as the scratch, brown and finish coat. Stucco is a very effective material to resist water leakage and preserve your house from any wall cavities but with its poor application it will surely damaged the whole thing.

Most home inspector now is ignorant on the occurring problem of stucco. So the result, buyers are deceived to buy the high priced subdivisions with very poor value material used.

Recently, foam sheathing or OSB (Oriented Strand Board) has been more applied rather than the traditional plywood sheathing. OSB has poor moisture resistant and it easily tends to delaminate when wet. Thus, foam sheathing rots faster than plywood’s do.

Another poor change on stucco application is the use of house wraps such as Tyveck rather than having the felt building paper as water resistive barrier. It is proven that when stucco is applied directly to a house wrap it lessens its resistive capability due to some chemical bond. Thus, it invites water leakage and mold growths

Therefore, if you are planning to buy house stucco make sure to hire a home stucco inspector that knows how to investigate properly on the stucco structure. For additional information, the effective way to diagnose leaks behind stucco is through infrared camera. It sees clearly the wall’s situation.

Bear in mind that a simple crack may mean a big problem or a big cash to spend. So, make sure that you buy a stucco house that is worth its value.
