Top 5 Most Common Reasons Stucco Can Fail Badly

Architecture is one of the most defining features of a building, and it shapes how the building functions and the way people live there. The most common material used in architecture is stucco, a plaster that is often applied as an exterior finish of buildings.

Stucco is a popular building material for both residential and commercial structures.

Over the years, stucco has proven to be one of the most durable, low-maintenance, and cost-effective materials used in construction. However, it has limitations, and when used improperly, it can lead to several problems.

This article will discuss some of the top reasons why stucco fails and provide solutions for those looking to avoid the issue. Stay tuned with us!

1. Doors and Window Sills Installed Incorrectly

One of the top reasons why stucco fails is because doors and window sills are installed incorrectly.

If these elements are not properly sealed, they can allow water to enter the home. This can cause the stucco to crack and crumble.

When installing new windows and doors, it is essential to add a layer of water-resistant paper beneath the sill and frame where water can get trapped, causing structural damage and mildew infestation.

Cracking and eventual degradation can be avoided if your stucco finish is effectively protected against moisture.

2. Faulty Sealing of Electric Outlets and Vents

Stucco can also fail due to faulty sealing of electrical outlets and vents. Over time, the sealant around these areas can degrade, allowing water and moisture to enter the underlying structure.

This can cause the wood framing to rot, leading to serious problems with the stucco exterior.

To avoid this problem, regularly checking the sealant around electrical outlets and vents is important. If any cracks or gaps are found, they should be repaired immediately. This will help to keep water and moisture out of the underlying structure and will help to prolong the life of your stucco exterior.

3. Improper Flashing Installation

Flashing is a thin strip of material used to seal the area where two different materials meet. When flashing is not installed properly, water can get behind the stucco and cause it to fail.

Inexperienced stucco contractors could overlook the need to install appropriate flashing around windows and doors to prevent the stucco surface from water damage.

“Kick-out flashing diverters”, which are one-piece molded plastic or metal pieces, are required between vertical walls, roof ends, external corners of chimneys, and fascia boards where gutters will be installed.

To fully protect the stucco finish from moisture, it is the stucco contractor’s responsibility to ensure that this sort of flashing is put in all of these areas and at the lowest inside corner of the structure.

4. Inadequate Deck Installation

Another reason stucco fails is because of inadequate deck installation. When installing decks, it is important to ensure that they are built correctly and are water-resistant.

If the deck is not properly installed, it can cause cracks and other problems with the stucco. The deck should be installed correctly before applying the stucco.

For taller decks, a skilled deck builder would utilize water management techniques like rain screens, barrier membranes, and ledger board drip caps,  flashing to protect the rim joists and anything below (the stucco).

For building a deck, an experienced stucco inspector can help you detect any potential issues and provide tips on keeping your stucco in good shape.

5. Material Transition Issues

When stucco is applied to a surface, it must adhere properly to create a strong bond. If there are any gaps or areas where the stucco does not adhere properly, it can cause the stucco to fail.

A lack of effective sealing of the joints between stucco and different materials like concrete, stone, siding, and brick can lead to cracking and water penetration, which can be exacerbated by the lack of proper sealing of these joints. Stucco may be protected from serious damage by properly flashing these seams, much like you would with windows, doors, and chimneys.

If you are having problems with your stucco, it is important to consult with a professional. They will be able to assess the situation and recommend the best course of action.

Other Minor Reasons Stucco Can Fail

We have discussed the top 5 reasons stucco can fail, however, there are some minor reasons that can result in stucco failure. Mostly homeowners ignore these issues, which leads to stucco damage. Some of the minor causes of stucco fail are:

  • If it is not properly cared for, it can become damaged and deteriorate.
  • Stucco is a mixture of cement, sand, and water. If any of these ingredients are not properly mixed, it can cause the stucco to fail.
  • If the wrong proportions of ingredients are used, it can cause the stucco to crack or crumble. It is important to follow the instructions carefully when mixing stucco.
  • If the application process is not followed correctly, the stucco will not adhere properly to the home and eventually start to come off.
  • Stucco must be applied in multiple thin layers to be effective. If it is applied too thickly, it can crack and fail.
  • Stucco can fail if it is not maintained properly. It must be cleaned and sealed regularly to protect it from the elements. It will eventually degrade and fail if it is not cared for properly.

The best way to avoid this issue is to hire a professional who can come out and inspect the job to ensure that all cracks and gaps are sealed.

FAQs

What’s causing my stucco to crumble?

Your home’s stucco may crumble or fall off due to water damage. Poorly placed or maintained stucco can lead to fractures in the foundation of your house and water infiltration problems.

Fortunately, your stucco exterior’s unsightly cracks and breaks are only the beginning of your problems.

How do you care for a stucco home?

In most cases, water and some elbow grease are all that is required to clean indoor stucco; that’s great news. Clean the discolored stucco with a wet nylon brush and rub the residue away with a damp microfiber towel (or clean cotton rag).

Does leaking occur because of stucco cracks?

Stucco cracks aren’t necessarily a sign of damage, but they are frequently an indication of moisture problems in the stucco.

Due to faulty drainage systems, you may observe water seeping through the stucco walls and dripping down the bottom of the wall.
