The customer service is great. If you call them you may get an AI taking your info but they record your phone number and a real person will call you back and fine tune everything. Their business operation is customer-friendly in that they can do the work without you being home and also provide a 30 day warranty on the work. They won't charge you until the work is done. I chose them because they had great reviews online and so far so good. I will review again once the work is done.
