GREAT COMPANY! GREAT SERVICE!They did a fantastic installation in my old Miami Beach home with poured concrete walls. That was over 22 years ago. When it was time to replace my "old" system they came in with a minimum of stress or mess and were done and out in 2 days not weeks. Everything works perfectly, the price was great and they are a pleasure to work with. They also provide me with expert service and maintenance.This family owned business (since 1974) will not disappoint you!Ask for Ellen or Richie. RHH, Miami Beach
