⛈️ The storm has passed—but it’s a good time to give your home a quick check.
After heavy rain, wind and thunderstorms, take a few minutes to look around your home for potential issues:

💧 Check basements, sump pumps and plumbing areas for signs of water or leaks.
⚡ Look for tripped breakers, damaged outdoor outlets or electrical issues—but never approach downed wires.
❄️ Check around your outdoor HVAC equipment for branches, debris or visible damage.
🔌 Pay attention to appliances or electronics acting differently after a power outage or surge.

Sometimes storm damage isn’t immediately obvious. If something doesn’t look, sound or operate normally, give Joseph Frederick & Sons a call.
