Preparing Your Walls for Summer Heat and Coastal Humidity

May 05, 20253 min read

Summer on the Central Coast, including beautiful areas like San Luis Obispo, Pismo Beach, Grover Beach, and Arroyo Grande, brings warm weather and plenty of sunshine. However, with the heat also comes high humidity, especially in coastal regions. This combination can be tough on your home's drywall, leading to warping, moisture buildup, and even mold growth if not properly managed.

Preparing your walls before summer hits can help maintain the quality of your living spaces and prevent costly repairs. Here are some essential tips for keeping your walls protected throughout the summer months.

Why Summer Heat and Coastal Humidity Affect Drywall

Drywall is a common building material because it’s cost-effective and easy to install. However, it’s also susceptible to moisture and temperature changes. Coastal areas like Pismo Beach and Grover Beach are particularly prone to humidity, which can seep into walls and weaken the drywall’s integrity. When hot air meets cooler indoor surfaces, condensation can form, leading to:

  1. Warped Walls: Humidity can cause drywall to absorb moisture and lose its shape.

  2. Peeling Paint: The combination of moisture and heat can cause paint to crack or bubble.

  3. Mold Growth: Persistent moisture creates a breeding ground for mold and mildew.

  4. Soft Spots: Prolonged exposure to humidity can soften the drywall, making it vulnerable to damage.

Top Tips for Protecting Your Walls from Summer Heat and Humidity

Seal Your Walls Properly

  • Use a high-quality, moisture-resistant paint on your drywall to create a protective barrier against humidity.

  • Apply a sealant to windows and door frames to prevent humid air from seeping inside.

Improve Indoor Ventilation

  • Proper airflow is crucial in coastal areas. Install exhaust fans in bathrooms and kitchens where moisture levels are higher.

  • Open windows during dry mornings to let in fresh air but close them during hot, humid afternoons.

Use Dehumidifiers

  • Dehumidifiers are essential for reducing moisture levels in living spaces. Place them in rooms most affected by humidity, like basements or coastal-facing walls.

Regular Maintenance Checks

  • Inspect your drywall regularly for signs of moisture damage, such as discoloration or soft spots.

  • Schedule routine maintenance before peak summer to ensure any small issues are addressed promptly.

Insulate Your Walls

  • Adding insulation can help regulate indoor temperatures and reduce condensation on walls. Choose moisture-resistant insulation materials when possible.

Keep Outdoor Spaces in Check

  • Coastal gardens and landscaping can increase moisture near your home. Trim plants away from walls and ensure proper drainage to reduce humidity buildup around the foundation.
