I worked with Stephen on my order and with his knowledge and guidance I ordered the perfect combination of products for my project. We replaced 2 old bathroom skylights with 46x46 curb mounted skylights and the outcome was outstanding; the bathrooms are now flooded with natural light and look amazing.Further, one unit was damaged on arrival. Stephen had a replacement unit dispatched same day. Superior customer service.When Im ready to install a couple of sun tunnels, Im going back to Stephen.
