"Just had lightning protection installed on our new house. The folks who did it were tremendous! Total experts in the UL and NFPA codes and recommendations. They are a UL Listed Company and a NFPA member using only UL-listed materials. Went out of their way to conceal the cables from really being seen. Not the cheapest, but really thorough, neat, and professional! I highly recommend them....4th generation family-owned company."
