Over the summer we built this playhouse for our grandkids and they love it. However, it was missing a key component, vinyl windows so the kids are protected from the elements if they decide to play in it during the fall or winter. We went into Quality Glass Block and they were beyond helpful and knew exactly what we were looking for. Thank you for helping us complete this project for our grandkids. They have enjoyed it this summer and I think they will keep on enjoying it for many more years.
