I would HIGHLY recommend going with another supplier. I've had a terrible time with my window installation
having been incorrectly invoiced,
had my emails and request for info ignored for *weeks* at a time -
and encountered a level of administrative incompetence
that truly makes me marvel that they are actually in business.
