Michael did an excellent job of replacing all my hardwired smoke detectors and my dining room chandelier. I provided the chandelier, but just described the smoke detectors I wanted when I set up the appointment and that is what he brought. Michael was polite, friendly, and provided a lot of useful information in response to my questions. Cost was a bit more tan I expected, but I had a $25 coupon that helped. SECCO isn't the cheapest service around, but they are reliable and do quality work.
