Mike was very informative of the wet and dry central vacuum system and took plenty of time to explain how it works and also answered all of my questions and worry . His price and workmanship was beyond what I expected from a contractor , he took all the old parts,rusts metal pipes and left me with a super clean garage. I could not have asked more,indeed I thought the total price he charge me was almost half of what others wanted.what a great experience .Thanks Mike at Ladden west vacuum
