If your house was built before 1977 - it could be toxic....

You already know PCBs are bad - but your house could be crawling with them...

PCBs, or polychlorinated biphenyls, were all the rage in building materials from the 19030s through 1977, when they were finally banned. PCBs were often used in paint, caulk, electrical wiring and fluorescent light fixtures. If you’ve still got the originals in your home those toxic chemicals could be wafting from room to room.

You can have your home tested for the prescense of PCBs for about $500. Most electricians are now trained to check your wiring for PCB material that could be deteriorating and pose a hazard.
