By MoonDance Painting·June 22, 2026·6 min read

Summer is the perfect season for exterior painting in Marin County. Learn the essential preparation steps — from inspection and power washing to priming and paint selection — that ensure a long-lasting, beautiful result.

Summer in Marin County brings beautiful weather, making it the perfect season for exterior home improvements. If you are considering an exterior painting project in San Rafael, Novato, or anywhere in the Bay Area, preparation is the key to a long-lasting and beautiful finish. At MoonDance Painting, we have spent over 20 years perfecting the art of exterior painting, and we know that a flawless result starts long before the first drop of paint is applied.

In this guide, we will walk you through the essential steps to prepare your home for a summer exterior painting project, ensuring that your investment stands the test of time.

Why Summer is Ideal for Exterior Painting in Marin County

The Mediterranean climate of Marin County offers warm, dry summers, which are ideal conditions for exterior painting. Paint needs consistent temperatures and low humidity to cure properly. The sunny days in towns like Mill Valley, Tiburon, and Sausalito provide the perfect window for completing large exterior projects without the unpredictable interruptions of rain or heavy fog.

However, the intense summer sun also means that preparation is more critical than ever. Proper prep work ensures that the premium paints we use, such as Benjamin Moore and Sherwin-Williams, adhere correctly and provide maximum protection against UV rays and coastal moisture.

Essential Preparation Steps Before Painting

Whether you are hiring a professional painting contractor in Marin County or considering a DIY approach, the preparation phase is non-negotiable. Here is what needs to happen before the painting begins.

1. Thorough Inspection and Repair

The first step in any exterior painting project is a comprehensive inspection of your home's exterior surfaces. Look for signs of damage, such as wood rot, peeling paint, cracks in stucco, or mildew. Any rotted wood must be replaced or repaired before painting. Small cracks in stucco or gaps around windows and doors should be filled with a high-quality exterior caulk to prevent water intrusion. Loose or peeling paint must be scraped and sanded to create a smooth, solid surface for the new paint to adhere to.

At MoonDance Painting, our free 60-minute on-site consultation includes a detailed inspection to identify any necessary repairs before we provide your detailed estimate.

2. Deep Cleaning and Power Washing

A clean surface is essential for paint adhesion. Over the years, your home's exterior accumulates dirt, dust, pollen, bird droppings, and mildew. Power washing is the most effective way to remove this buildup. However, it is crucial to use the correct pressure and techniques to avoid damaging the siding or forcing water behind the exterior cladding. For homes in areas like Belvedere or Corte Madera that may experience coastal moisture, a mildewcide treatment may also be necessary to eliminate any fungal growth.

3. Protecting Your Property and Landscaping

Before the scraping, sanding, and painting begin, it is vital to protect your property. Shrubs, flower beds, and trees near the house should be covered with breathable drop cloths to protect them from paint drips and debris. Driveways, walkways, and patios should also be covered to prevent accidental spills. Our crews at MoonDance Painting treat your home with the utmost care, ensuring that your property is fully protected throughout the project.

4. Priming the Surface

Once the surface is clean, repaired, and dry, the next step is priming. Primer acts as a bonding agent between the bare surface and the topcoat of paint. It also helps to seal porous surfaces and block stains. While some modern paints are "paint and primer in one," a dedicated high-quality primer is often necessary for exterior surfaces, especially if you are making a significant color change or painting over bare wood or stucco.

Professional vs. DIY Preparation

While some homeowners may be tempted to tackle exterior painting themselves, the preparation phase is often where DIY projects fall short. Here is a comparison of what you can expect when you hire a professional painting contractor in the Bay Area versus doing it yourself.
