Image of a residential standby generator, demonstrating the importance of using professional soft washing techniques to safely clean a home's exterior. If you live in the Tallahassee area, you know that a whole-house generator has become less of a luxury and more of a necessity. After storms like Hurricane Michael left many of us without power for a week, we’ve seen a huge increase in homeowners installing systems, with Generac being the most common brand we see on the job.

But with this wise investment comes a new question we hear from customers almost daily: “How do you safely clean around the generator’s disconnect panel on the side of my house?”

This is a critical question. Just today, a new customer told us their installation contractor warned them that any water damage from pressure washing would void their warranty. Many of these panels are even marked with a “Do Not Pressure Wash” sticker. With a local realtor telling us the estimated replacement cost is around $3,000-$4,000, the stakes are simply too high to get it wrong.

The Dangers: Why You NEVER Pressure Wash Electrical Panels

The exposed generator isolation switch panel on a home's exterior before being professionally protected for a house wash in Tallahassee, Florida. While exterior electrical panels are designed to be weather-resistant against rain, they are not built to withstand the intense, direct force of a pressure washer. Forcing water past the panel’s seals can lead to catastrophic failure and serious hazards, including:

  • Short Circuits: Water ingress can cause immediate damage to the sensitive electrical components inside, leading to costly repairs.
  • Corrosion: Moisture trapped inside the panel will lead to rust and corrosion on terminals and wiring, compromising the integrity and safety of your system over time.
  • Serious Electrical Hazards: Introducing high-pressure water into an electrical panel creates a significant risk of electric shock.

As official Generac maintenance guidelines and general safety protocols confirm, using a pressure washer on or near these critical components can cause far more harm than good.

Our Professional Process: The Safe Way to Clean

The short answer is: We don’t.

Instead, we follow a strict, multi-step safety protocol that is included with every home wash we perform. Our best practice is to protect your investment, not risk it.

  1. Identify & Protect: The first step is to identify all critical electrical components, including the generator’s disconnect panel. We then completely cover the entire panel using a durable plastic tarp.
  2. Seal: We meticulously seal the edges of the tarp with high-quality, waterproof tape. This creates a watertight barrier that prevents any water or cleaning solution from reaching the panel.
  3. Soft Wash Around: With the panel safely covered, we proceed with our gentle, low-pressure Soft Wash House Washing technique. We carefully clean the siding around the protected area, ensuring a perfect clean without any risk of water intrusion.
  4. Remove & Inspect: Once the washing and rinsing are complete, we carefully remove the protective covering, leaving your panel just as we found it—safe and dry.
