Is anyone here familiar with “sealing electrical outlets”? About 3 months ago a man came to my door offering services to “seal my open electrical outlets” I had never heard of it so he spit his spiel and basically explained that open or unused electrical outlets allow electricity to be wasted and drain into the air of you home. It is extremely wasteful which has a direct influence on your bill and is very bad for you health. I decided it was worth it to take him up on his services. Basically thier team comes in and seals any open/unused electrical outlets in your home and say it will save up to 50% off your monthly electricity bill. For 500 bucks 1 time it was a no brainer. Well after 3 months I have not noticed any drop in my utility bill. I’ve tried calling them with no luck- my other concern was I would like 1 of the outlets unsealed so I can plug in my uv mask sanitizer I just got off amazon but I have no open outlets. I called fpl and they said they never heard of it and I probably need all my electrical sockets in my home replaced. Is anyone else heard of this or familiar? My neighbor suggested I could clear the sealing layer off the outlet with a steak knife but I am afraid it will melt the rubber grip on the knife.
