Simple Steps to Keep Your Veneer Safe

Here are some simple and smart ways to protect them from water damage:

1. Check Your Drainage System

Your gutters and downspouts should direct water away from the home and not let it pool around the walls. Make sure they’re clean, free from blockages, and directing water at least 3 feet from your foundation.

2. Seal It Right

Apply a high-quality water-repellent sealer for added protection. This sealer prevents moisture from penetrating the surface while still allowing the stone to “breathe.”

3. Regular Inspections

Veneers can crack or develop gaps, particularly in areas exposed to frequent sun and rain. That’s why it’s important to inspect them at least once a season. If you notice any damage, contact a masonry expert right away before it worsens.

4. Slope the Ground Away

The soil around your home should slope down and away from your walls. This will prevent the water from pooling near the base, which can weaken the surface and even affect the foundation of your home.

5. Install Flashing

Flashing is a thin barrier installed behind your stone veneer, usually at joints and corners. It helps move water out and away before it can cause harm. Flashing might sound like a job for the pros and it is.

6. Avoid Pressure Washing

It might seem like a good idea to blast away dirt, but high-pressure water can push moisture behind the surface or even loosen stones. Instead, use a soft brush and a gentle hose for cleaning.

What to Do After a Flash Flood

Here’s what to do if a flash flood occurs in your area:

  • Inspect your veneer: Look for loose stones, visible cracks, or areas where water might have moved behind the surface.
  • Dry things out: To reduce the humidity inside your house, use fans and dehumidifiers. It will prevent moisture from affecting indoor walls.
  • Call a pro: Even if things look okay, hidden damage can show up weeks later. A professional inspection from a trusted contractor can save you from future headaches.
