Konzept Automation was indeed the best value and aside from the reasonable estimate we valued that Anna's husband, Alex, was doing the installation himself. As my own husband, a former self-employed renovator, Alex was touted as being very meticulous. Indeed he is. When estimating as well as installing, he looked and checked for particular details peculiar to our condo. He installed 8 window coverings, the total width of the 30' unit, in just over 2 hours efficiently with the aid of an assistant and leaving the unit free from drywall dust and product debris. I would highly recommend this likeable, hard-working, professional and qualified couple's business, Konzept Automation.
