⚠️ Public Service Announcement from MI Electrician L.L.C. ⚠️
If you’re drilling through a rim joist that’s been sealed with spray foam—always remove the foam first.
We’re seeing more and more cases where wires are hidden behind spray foam, and drilling blindly can easily damage electrical circuits. What looks like a clean spot can actually have live wiring buried just beneath the surface.
This can lead to:
• Power loss to critical appliances
• Fire hazards from damaged conductors
• Costly repairs that could have been avoided
Before you drill, take the extra few minutes to carefully clear the foam and inspect the area. It’s a simple step that can prevent serious damage.
When in doubt—call a professional.
