Let us talk about Stucco Inspections. If you own a home in Fontana, you probably have stucco. It is a solid material. Stucco is built to handle our hot summers as well as the heavy rains we get. But "solid" does not mean "perfect". Ignoring your stucco can cause real problems later on. We have seen this happen many times with Stucco Inspections in Fontana.

This is not about getting a fancy, expensive inspection every year. This is about being smart and also being proactive. You can do a lot of the first checks yourself. Knowing what to look for will help you decide when to call in a professional Stucco Contractor like us at Fontana Stucco & Plastering.

Before You Start: Your DIY Prep Work for Stucco Inspections

Before you even think about calling a Stucco Contractor, you should do a basic visual inspection. It is like checking your car tires before a long trip. Grab a notepad as well as a pen as well as your phone for pictures. Walk around your entire house slowly. Look at every wall. Pay attention to areas around windows as well as doors as well as the foundation.

  • Clear the perimeter: Make sure shrubs are not touching your stucco. Plants can trap moisture against the wall. This is not good for your stucco. In addition, it makes it hard to see what is happening.
  • Good lighting is important: Do this Stucco Inspection on a bright day. This helps you see details clearly. Sometimes shadows can hide small cracks or discoloration.
  • Know your home's history: Did you just buy the place? Was there a repair done before you moved in? Have there been any past leaks? This information helps you focus your Stucco Inspection in Fontana.

During Your DIY Visual Stucco Inspection: What to Look For

Now it is time for the actual looking. You are searching for signs that your stucco is not working right. Think of yourself as a detective during this Stucco Inspection.

Cracks: Not All Cracks Are the Same

You will probably see some cracks during your Stucco Inspection. Stucco is stiff. Houses settle over time. Minor hairline cracks are common. This is especially true with our temperature changes here in the Inland Empire. These cracks are usually not a big problem. However, they can let moisture in if they are not fixed.

  • Hairline cracks: These cracks are very thin. They are like a strand of hair. If they are in one spot and not getting bigger, you might be able to seal them yourself. You can use an elastomeric caulk for this type of Stucco Repair.
  • Larger cracks (wider than 1/8 inch): These cracks are a serious sign. We are talking about cracks that you can easily put a credit card into. They often show structural movement. They can also mean foundation issues. In addition, they might point to a problem with the stucco system itself. Look for diagonal cracks around windows as well as doors. That is a classic sign of foundation issues during a Stucco Inspection.
  • Cracks with staining: If a crack has dark streaks or discoloration around it, water is getting in. That is when you need to call a Stucco Contractor for a Stucco Inspection.

Discoloration and Stains: Signs of Moisture

Stains are often a clear sign of moisture problems during a Stucco Inspection.

  • Dark streaks or spots: Look for these especially around windows as well as doors as well as rooflines. Also check at the base of the wall. These signs mean water is getting behind the stucco.
  • White, powdery residue (efflorescence): This is salt that is left behind. It happens when water seeps through the stucco and then evaporates. It is a clear sign of moisture getting in. This is important to note during your Stucco Inspection.
  • Mold or mildew: Any green, black, or fuzzy growth on your stucco points to constant dampness. This needs attention from a Stucco Contractor in Fontana.

Bulging, Soft Spots, and Hollow Sounds: Serious Problems

These signs usually mean there is a problem. The stucco might be detaching from the wall. Or there could be significant water damage behind it. This is a serious finding during a Stucco Inspection.

  • Bulging or blistering: If sections of stucco look like they are puffing out or bubbling, it is often because of trapped moisture. This needs a professional Stucco Inspection.
  • Soft spots: Press firmly on areas that look suspicious or discolored. Healthy stucco should feel very hard. If it feels soft, spongy, or crumbles, you have deterioration. You likely have moisture damage. This needs immediate attention from a Stucco Contractor.
  • Hollow sounds: Tap the stucco gently with a rubber mallet or your knuckles. If you hear a hollow sound instead of a solid thud, it can mean the stucco has separated from the wall underneath. This is a key finding for a Stucco Inspection.

Around Openings and the Foundation during Stucco Inspections

Pay extra attention to where your stucco meets other materials. This is important for a thorough Stucco Inspection.

  • Windows and doors: Check the caulk as well as the flashing around these. Gaps or cracked caulk are places where water can get in.
  • Weep screeds: This is a metal strip at the very bottom of your stucco. It lets any trapped water drain out. Make sure it is not buried by landscaping or dirt. If it is blocked, water cannot escape. This is a common issue for Stucco Inspections.
  • Foundation: Look for any cracks or damage where the stucco meets the foundation. This area is important for a Stucco Inspection in Fontana.

When to Call a Professional Stucco Contractor (That Is Us!)

You have done your visual check. You have found some things that make you nervous. Here is when it is definitely time to get a professional Stucco Contractor involved for a Stucco Inspection:

  • Any large cracks: Call us if they are wider than 1/8 inch. Also call if they are growing or spreading from corners.
  • Persistent staining or discoloration: This is especially true if it keeps coming back after you have cleaned it. This means there is an ongoing moisture issue.
  • Bulging, soft spots, or hollow areas: These are strong signs of underlying damage. You cannot fix these with a simple patch. A professional Stucco Inspection is needed.
  • Mold or mildew that will not go away: This suggests a constant source of moisture. Our Stucco Contractors can help with this.
  • If you are unsure: Honestly, if you are just not sure what you are looking at, call us. It is better to be safe than sorry. We have specialized tools. These include moisture meters. They help us see what is really going on behind the surface. We can do this without tearing your walls apart right away.
  • Before buying or selling: A professional Stucco Inspection is a smart move for your peace of mind. Fontana Stucco & Plastering offers these services.

We are not just looking at the surface during a Stucco Inspection. We are looking at the whole system. This includes flashing as well as drainage as well as how it was installed. Sometimes, what looks like a small crack on the outside can be a much bigger problem on the inside. Improper installation is a common cause of stucco failure. We have seen plenty of that over the years during our Stucco Inspections in Fontana.
